This is a shaft product designed from the perspective of customer procurement and use pain points. It is not just a transmission part, but a systematic solution to help customers reduce costs and improve efficiency, focusing on the design concept of "making transmission simpler".
1. Cost Reduction: Reduce the purchase of additional parts such as positioning sleeves, retaining rings, and adjusting gaskets, effectively reducing the comprehensive cost of shaft system.
2. Efficiency Improvement: Assembly does not require repeated alignment and adjustment, greatly improving assembly efficiency and shortening the whole machine production cycle.
3. Reliability: Optimized stress distribution reduces shaft breakage risk, integrated sealing reduces oil leakage and dust ingress, effectively reducing equipment failure rate.
4. Worry-free: Standardized process ensures stable mass production with high dimensional consistency, simple later maintenance and replacement, no need for repeated debugging and adaptation.
With mature technology, Double Step Type Motor Shaft is our mature mass-produced shaft type, which is widely recognized by global customers.
Compared with ordinary optical shafts and single-step shafts on the market, our double-step shafts have four irreplaceable design advantages, which solve the inherent defects of traditional shafts from the structure.
1. Precise Step Positioning: The step end face is processed by high-precision surface grinding, parts are positioned accurately when leaning against it, no need to repeatedly adjust gasket thickness, and no need to worry about positioning movement during operation.
2. Scientific Load Distribution: The large diameter section bears torque, and the small diameter section is equipped with seals. Different shaft diameters match corresponding load levels, with uniform stress distribution, effectively improving torsional strength and bending strength, and reducing fatigue fracture risk under long-term high load.
3. Natural Spigot Self-alignment: The spigot formed by the step outer circle and end face makes bearings and end covers automatically coaxial when sleeved in, no need for dial indicator alignment. Even new workers can achieve reliable assembly accuracy, avoiding problems of bore sweeping and abnormal noise caused by misalignment.
4. Integrated Sealing Structure: The sealing groove is directly made at the step, and the sealing ring will not shift against the step side. The sealing effect is more reliable than the sealing groove separately opened on the optical shaft, effectively reducing oil leakage and dust ingress problems, and prolonging bearing service life.
These unique design features make Double Step Type Motor Shaft perform better than traditional shaft products in high-load, high-reliability scenarios.
All parameters come from actual mass production test data, no false marking. Conventional specifications strictly implement the following accuracy standards, and special requirements can be customized:
| Parameter Item | Specification Range | Accuracy Standard |
|---|---|---|
| Single step width | 3~8 mm | Width tolerance ±0.02mm |
| Shaft straightness | - | ≤0.03 mm / 100 mm |
| Journal radial runout | - | ≤0.02 mm |
| Step end face roughness | - | Ra ≤ 1.6~3.2 μm |
| Step transition fillet | R0.5~R2 mm | Customizable |
| Shaft outer diameter range | φ5~φ60 mm | Tolerance up to h6 level |
| Common materials | - | 45# steel, 40Cr, bearing steel, stainless steel |
| Heat treatment hardness | - | HRC25-60 customizable |
Note: All accuracy standards are stably achievable in mass production, not ideal laboratory data. Batch supply can guarantee compliance with the above parameter requirements.
This is the value most feedback by customers after use - no more worrying about shaft problems, worry-free from assembly to later maintenance, solving many pain points for procurement and production.
1. Lower Assembly Threshold: Workers can assemble according to the steps, no need for repeated dial indicator alignment, no need to grind gaskets to adjust clearance, greatly reducing the dependence on experienced workers, and avoiding defective products caused by manual operation errors.
2. Reduce Debugging Time: Parts are automatically positioned by the step structure, the assembly clearance meets requirements after installation, reducing the situation of unable to rotate or abnormal noise requiring disassembly and reassembly, and shortening factory debugging time.
3. Reduce Operation Failures: Reasonable stress distribution makes shaft breakage less likely, reliable sealing makes oil leakage and dust ingress less likely. After-sales repair reports are reduced after equipment is sold, saving after-sales service cost.
4. Convenient Maintenance and Replacement: Standard parts have high consistency. For after-sales shaft replacement, just take one and install it directly, no need for custom manufacturing or secondary processing, and spare parts inventory management is simpler.
5. Simplify Inventory Management: One shaft integrates multiple functions of positioning, sealing and load bearing, reducing the types of spare parts such as positioning sleeves and retaining rings, and reducing inventory capital occupation.
Many customers feedback that after using Double Step Type Motor Shaft, the workshop assembly efficiency is significantly improved, and after-sales problems are reduced. This is the actual value that good products bring to customers.
