Guideway linier

Sebagai komponen transmisi inti dalam otomatisasi industri dan peralatan presisi, pemilihan panduan linier secara langsung terkait dengan keakuratan, efisiensi, kehidupan, dan stabilitas peralatan. Artikel ini akan memberi para insinyur referensi seleksi sistematis dari aspek prinsip seleksi, parameter utama, langkah dan tindakan pencegahan, dikombinasikan dengan skenario aplikasi aktual.Analisis parameter utama sebelum pemilihan1. Kapasitas dan arah bebanTipe Beban: Perlu untuk mengklarifikasi beban statis (gaya vertikal dan lateral) dan beban dinamis (gaya inersia yang disebabkan oleh akselerasi) yang ditanggung oleh peralatan.Arah beban: Panduan linier biasanya dapat menahan beban empat arah, tetapi tata letak Raceway dan distribusi slider dari pemandu perlu dipilih sesuai dengan arah gaya yang sebenarnya.Keseimbangan Torsi: Pusat posisi gravitasi dan torsi perlu dihitung dalam aplikasi kompleks untuk menghindari deformasi atau masa pakai pemandu yang lebih pendek karena gaya yang tidak merata.2. Tingkat akurasiPilih tingkat biasa (± 50μm), tingkat presisi (± 10μm) atau tingkat presisi ultra-tinggi (± 5μm) sesuai dengan persyaratan aplikasi. Misalnya, peralatan semikonduktor membutuhkan akurasi penentuan posisi tingkat nanometer, dan panduan presisi yang sangat tinggi harus dipilih.3. Jenis dan Bahan PanduanPilihan jenis:Panduan Rolling (Bola/Roller): Gesekan rendah, kecepatan tinggi, cocok untuk pemrosesan berkecepatan tinggi dan posisi presisi.Panduan Sliding: Kapasitas penahan beban yang kuat, cocok untuk skenario beban berat dan berkecepatan rendah.Adaptasi material:Baja karbon: penahan beban tinggi, cocok untuk industri berat;Stainless Steel: tahan korosi, cocok untuk lingkungan yang lembab atau korosif;Paduan Aluminium: Ringan, cocok untuk peralatan medis atau skenario beban ringan.4. Kemampuan beradaptasi lingkungan Lingkungan seperti suhu tinggi, kelembaban, debu atau media korosif memerlukan pelapis tahan suhu tinggi, desain tahan debu yang disegel atau solusi pelumasan khusus.  Langkah Pemilihan Panduan Linier1. Persyaratan yang jelasTentukan kecepatan gerakan, akselerasi, panjang stroke, dan ruang pemasangan peralatan28.2. Hitung beban dan umurHitung kapasitas beban panduan sesuai dengan rumus beban (seperti beban pengenal statis dan beban pengenal dinamis), dan merujuk pada rumus perhitungan masa pakai yang disediakan oleh pabrikan (seperti pengenal umur L10) untuk mengevaluasi siklus pemeliharaan.3. Pilih Spesifikasi PanduanLebar panduan: Semakin lebar lebar, semakin kuat kekakuan dan kapasitas beban. Spesifikasi umum adalah 15mm hingga 45mm.Level preload: Tidak ada preload, preload ringan, preload sedang atau preload berat. Semakin tinggi preload, semakin kuat kekakuannya, tetapi resistensi gesekan meningkat.4. Desain Pelumasan dan PemeliharaanPilih sistem pelumasan atau pelumasan diri yang terpusat, membersihkan debu secara teratur dan tambahkan minyak untuk mengurangi keausan. Skenario aplikasi khas dan kasus seleksi1. Alat mesin CNCPersyaratan: Pengulangan tinggi (± 5μm), kekakuan tinggi.Pilihan: Panduan rol presisi ultra-tinggi, baja karbon, desain preload berat, dengan sistem umpan balik loop tertutup.2. Robot IndustriPersyaratan: Gerakan fleksibel dengan beberapa derajat kebebasan, resistensi terhadap start dan berhenti yang sering.Pilihan: Panduan bola gesekan rendah, stainless steel, struktur penyegelan kedap debu.3. Peralatan semikonduktorPersyaratan: Penentuan posisi tingkat nano, ketahanan terhadap lingkungan kamar yang bersih.Seleksi: Panduan mengambang udara atau panduan suspensi magnetik, tingkat presisi ultra-tinggi, solusi pelumasan bebas debu.Kesalahpahaman umum dan tindakan pencegahan dalam seleksiMengabaikan dampak beban dinamis: Hanya mempertimbangkan beban statis yang dapat menyebabkan panduan gagal karena kelebihan gaya inersia selama gerakan berkecepatan tinggi.Mengejar presisi tinggi yang berlebihan: Menggunakan panduan presisi yang sangat tinggi dalam skenario non-presisi akan meningkatkan biaya, dan nilai biasa dapat memenuhi kebutuhan.Adaptasi lingkungan yang tidak mencukupi: Kegagalan untuk memilih desain pelindung untuk debu atau lingkungan korosif akan sangat memperpendek umur pemandu.Instalasi dan pemeliharaan yang tidak tepat: Penyesuaian preload yang tidak memadai atau kurangnya pelumasan akan secara langsung mempengaruhi akurasi dan stabilitas gerak.RingkasanPemilihan panduan linier perlu secara komprehensif mempertimbangkan beberapa faktor seperti beban, akurasi, lingkungan, biaya, dll., Dan secara fleksibel menyesuaikannya sesuai dengan skenario aplikasi yang sebenarnya. Melalui perhitungan ilmiah, parameter pencocokan yang masuk akal dan pemeliharaan rutin, kinerja pemandu dapat dimaksimalkan dan umur peralatan dapat diperpanjang. Dianjurkan untuk berkomunikasi penuh dengan pemasok dan insinyur di awal pemilihan, dan menggunakan alat profesional (seperti perangkat lunak perhitungan beban) untuk mengoptimalkan solusi untuk memastikan keseimbangan antara efisiensi dan keandalan.Jika Anda perlu mengetahui lebih banyak tentang parameter model tertentu atau kasus aplikasi, Anda dapat merujuk ke manual pemilihan atau dokumen teknis yang disediakan oleh produsen.

Para insinyur merekomendasikan material berdasarkan kelembapan sekitar dan jenis cairan kontak!

【Linear guides】can be categorized into ball linear guides, roller linear guides, and wheel linear guides. They are used to support and guide moving parts, enabling them to perform reciprocating linear motion in a given direction. Based on the nature of friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides.   1. Definition: Linear guides, also known as linear rails, slide rails, or linear guides, are used in linear reciprocating motion applications and can withstand a certain amount of torque, achieving high-precision linear motion under high loads.   2. Function: The function of linear guides is to support and guide moving parts, enabling them to perform reciprocating linear motion in a given direction. Linear bearings are mainly used in automated machinery, such as German-imported machine tools, bending machines, and laser welding machines. Of course, linear bearings and linear shafts are used in conjunction. Linear guides are mainly used in mechanical structures with high precision requirements. The moving and stationary elements of a linear guide do not require an intermediate medium; instead, rolling steel balls are used.   3. Working Principle: It can be understood as a rolling guide, where steel balls endlessly roll and circulate between the slider and the guide rail, allowing the load platform to move easily and linearly along the guide rail with high precision. This reduces the coefficient of friction to one-fiftieth of that of traditional sliding guides, easily achieving very high positioning accuracy. The end-unit design between the slider and the guide rail allows the linear guide rail to simultaneously bear loads in all directions (up, down, left, and right). The patented recirculation system and simplified structural design make HIWIN's linear guide rails have smoother and lower noise movement. The slider transforms the motion from a curve to a straight line. Like planar guide rails, linear guide rails have two basic components: a fixed component that acts as a guide, and a moving component. Since linear guide rails are standard components, for machine tool manufacturers, the only task is to machine a mounting plane and adjust the parallelism of the guide rail. The guide rail, acting as a guide, is made of hardened steel and is precision ground before being placed on the mounting plane. For example, a guide rail system that withstands both linear forces and overturning moments is significantly different in design from a guide rail that only withstands linear forces. Over time, the steel balls begin to wear, weakening the preload acting on them and reducing the motion accuracy of the machine tool's working parts. To maintain initial accuracy, the guide rail support, or even the guide rail itself, must be replaced. If the guide rail system already has a preload, and system accuracy has been lost, the only solution is to replace the rolling elements. The guide rail system is designed to maximize the contact area between the fixed and moving elements. This not only improves the system's load-bearing capacity but also allows it to withstand the impact forces generated by intermittent or heavy cutting, widely distributing the force and expanding the load-bearing area. To achieve this, guide rail systems use various groove shapes, with two representative types: Gothic (pointed arch) grooves, which are extensions of a semicircle with the contact point at the apex; and arc-shaped grooves, which serve the same purpose. Regardless of the structural form, the goal is the same: to maximize the contact radius of the rolling steel balls with the guide rail (fixed element). The key factor determining the system's performance characteristics is how the rolling elements contact the guide rail.   4. Application Areas: ① Linear guides are mainly used in automated machinery, such as German-imported machine tools, bending machines, laser welding machines, etc. Linear guides and linear shafts are used in conjunction. ② Linear guides are primarily used in mechanical structures with high precision requirements. The moving and fixed components of a linear guide do not use an intermediate medium but rather rolling steel balls. This is because rolling steel balls are suitable for high-speed motion, have a low coefficient of friction, and high sensitivity, meeting the working requirements of moving parts, such as tool holders and slides in machine tools. If the force acting on the steel balls is too large, or the preload time is too long, it will increase the resistance of the support movement.   5. Precautions for Use: Prevent Rusting: When handling linear guides directly by hand, thoroughly wash away sweat and apply high-quality mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer. Keep the Environment Clean: Keep the linear guides and their surrounding environment clean. Even tiny dust particles invisible to the naked eye entering the guides will increase wear, vibration, and noise. Installation requires careful attention. Linear guides must be installed with utmost care. Forceful impacts, direct hammering, and pressure transmission through rolling elements are strictly prohibited. Appropriate installation tools are essential. Use specialized tools whenever possible, avoiding the use of cloths or short-fiber materials.   6. Cleaning the Guides: As core components of the equipment, guides and linear shafts function as guides and supports. To ensure high machining accuracy, the guides and linear shafts must possess high guiding precision and good motion stability. During operation, the workpiece generates significant amounts of corrosive dust and fumes. Long-term accumulation of these dust and fumes on the guide and linear shaft surfaces significantly impacts machining accuracy and can form pitting, shortening the equipment's lifespan. To ensure stable machine operation and product quality, regular maintenance of the guides and linear shafts is crucial. Note: For cleaning guides, prepare a dry cotton cloth and lubricating oil. Engraving machine guides are divided into linear guides and roller guides. Cleaning the linear guide rail: First, move the laser head to the far right (or left) to locate the linear guide rail. Wipe it with a dry cotton cloth until it is shiny and dust-free. Add a small amount of lubricant (sewing machine oil is acceptable; do not use machine oil). Slowly move the laser head left and right a few times to distribute the lubricant evenly. Cleaning the roller guide rail: Move the crossbeam to the inside, open the end covers on both sides of the machine, locate the guide rail, and wipe the contact areas between the guide rail and the roller with a dry cotton cloth. Then move the crossbeam and clean the remaining areas.   7. Development Prospects: With the continuous expansion of industries such as power, data communication, urban rail transit, automobiles, and shipbuilding, the demand for linear guide rails will grow rapidly. The linear guide rail industry has huge development potential in the future.   【Slide Block】The slide block material itself has appropriate hardness and wear resistance, sufficient to withstand the friction of movement. The hardness of the cavity or core part on the slide block should be the same level as other parts of the mold cavity and core. 1. Industrial Process Equipment: Molds are crucial process equipment for producing various industrial products. With the rapid development of the plastics industry and the widespread application of plastic products in aerospace, electronics, machinery, shipbuilding, and automotive industries, the requirements for molds are becoming increasingly stringent. Traditional mold design methods are no longer adequate. Compared to traditional mold design, Computer-Aided Engineering (CAE) technology offers significant advantages in improving productivity, ensuring product quality, reducing costs, and alleviating labor intensity.   2. Applications: Widely used in spraying equipment, CNC machine tools, machining centers, electronics, automated machinery, textile machinery, automotive, medical devices, printing machinery, packaging machinery, woodworking machinery, mold making, and many other fields.   If you have any questions in this regard, our product experts are happy to answer them!

The linear guide slider achieves efficient continuous operation 24 hours a day without jamming. The core reason lies in the synergistic effect of its structural design, lubrication system, and material manufacturing process, while the accompanying installation and maintenance specifications also play a crucial role. Specifically, this can be divided into the following aspects: High-precision rolling friction structure, replacing sliding friction The core of the linear guide is the rolling contact between the balls/rollers inside the slider and the guide rail. Compared to the surface contact of traditional sliding guides, the coefficient of friction in rolling contact is extremely low. This structure significantly reduces resistance and heat generation during operation. Even during long-term continuous operation, excessive frictional heat will not cause component expansion and jamming. Simultaneously, the circulating design of the balls/rollers ensures that the slider receives uniform force throughout its movement, without any jamming or interruption points. A stable and reliable lubrication system ensures long-term operation. Lubrication is a core element in preventing jamming. Linear guides are typically equipped with a long-lasting lubrication structure: The slider has a built-in oil reservoir and grease holder to store sufficient grease, continuously supplying oil to the ball/guide contact surfaces during operation, forming an oil film and reducing wear and resistance from direct metal-to-metal contact. Some industrial-grade guides also support automatic lubrication systems, which can replenish lubricant at regular intervals and in measured amounts to meet the lubrication needs of 24-hour uninterrupted operation. High-quality grease possesses high-temperature resistance, anti-aging properties, and load-bearing capacity, and will not be lost or fail due to temperature increases during prolonged operation. High-rigidity, wear-resistant materials and surface treatment processes The core components of the guide rails and sliders are generally made of high-carbon chromium bearing steel. After quenching, the hardness can reach HRC58~62, possessing extremely strong wear resistance and fatigue resistance. They are not prone to wear or deformation during long-term operation, avoiding jamming caused by component deformation. The guide rail surface undergoes precision grinding, achieving a roughness of Ra0.1~0.2μm. Combined with high-precision grinding of the ball bearings, this ensures smooth movement. Some products also undergo chrome plating, nitriding, and other surface treatments to further enhance wear resistance and rust prevention, preventing jamming caused by corrosion. Sealed and dustproof design to isolate external impurities Impurities (such as dust and iron filings) entering the slider are a common cause of jamming. Therefore, linear guides are equipped with professional seals: Dustproof sealing rings are installed at both ends of the slider, and a scraper plate is also provided on the outside to remove dust and debris from the guide surface, preventing them from entering the ball circulation channel; In harsh working conditions, dust covers, bellows, and other accessories can be added to completely isolate external contaminants, ensuring the cleanliness of internal moving parts and maintaining long-term smooth operation. Proper installation and load matching In practical applications, correct installation accuracy and load selection are also prerequisites for 24-hour jam-free operation: During installation, ensure the parallelism and straightness of the guide rail to avoid uneven force on the slider, uneven wear, and jamming due to installation deviations; During selection, choose a guide rail of appropriate specifications according to the actual load to ensure that the load is within the rated range and prevent overload from causing ball deformation or jamming.
