As a professional manufacturer of high-precision shaft products in China, Guanshuo relies on more than ten years of precision hardware processing experience and 11 patent technology accumulations to provide customers worldwide with high-performance Rectangular Spline Motor Shaft products. We implement whole-process quality control from raw material selection to finished product delivery, equipped with advanced CNC processing equipment and complete inspection systems. Our products have passed ISO9001 quality system certification, widely used in new energy vehicles, industrial automation, heavy machinery and other fields, and have become the core supplier for many leading enterprises in the industry.
This product adopts an innovative multi-tooth structure design, with multiple teeth sharing the load together, achieving smoother torque transmission effect. Compared with traditional single-key, double-key and multi-keyway products, it has more outstanding performance in impact resistance and eccentric load resistance, and can stably adapt to various complex and harsh working environments.
1. Stronger load capacity: The multi-tooth uniform force design effectively disperses working load, increasing load capacity by more than 40% compared with ordinary flat key connections, and can withstand larger torque output.
2. Higher centering accuracy: The spline structure naturally has good guidance and centering performance, ensuring high-precision fitting between shaft and hub, reducing eccentric vibration during operation.
3. Excellent guidance performance: The tooth side fitting clearance is precisely adjusted, realizing smooth axial sliding of parts on the shaft, meeting complex transmission requirements such as speed change and direction change.
4. Longer service life: The overall force is uniform, avoiding the stress concentration problem of single-key connection, effectively reducing the risk of tooth fracture and wear failure.
Under heavy load impact working conditions, the multi-tooth cooperative structure of Rectangular Spline Motor Shaft can effectively absorb instantaneous impact load, avoid component damage caused by excessive local stress, greatly reduce equipment downtime and maintenance probability, and provide reliable guarantee for customers' continuous production.
In the production process, we adopt professional processes such as gear hobbing and form grinding, strictly control tooth profile accuracy and indexing accuracy, precisely adjust fitting clearance, ensure stable transmission and lower noise during equipment operation, and comprehensively improve end users' experience. Raw materials are selected from high-quality alloy steel and carbon steel, processed through precision heat treatment technology, achieving the perfect combination of high hardness on tooth surface and high toughness in core part, with excellent anti-fatigue, wear resistance and fracture resistance properties, significantly extending product service life.
1. Precision gear hobbing process: Processed by professional high-precision hobbing machines, ensuring tooth profile error controlled at micron level with good tooth direction consistency.
2. Form grinding processing: Precision grinding by CNC cylindrical grinders, surface roughness reaching mirror level of Ra ≤ 0.8μm.
3. Professional heat treatment: Through carburizing quenching, tempering and other heat treatment processes, core part maintains good toughness.
4. Full inspection quality control: Every product undergoes full-item inspection through gear testing center, cylindricity measuring instrument, two-dimensional projector and other equipment, unqualified products will never leave the factory.
The shaft has extremely strong adaptability. It can be produced according to national standards, also can customize tooth number, pressure angle, tooth width and positioning method according to customer requirements. We also can provide various surface treatments such as blackening, zinc plating, nickel plating to enhance product corrosion resistance and assembly smoothness.
We organize production strictly in accordance with international standards and industry norms, all key dimensional accuracies are strictly inspected to ensure product interchangeability and transmission reliability. The following are the core accuracy parameters of the product, all indicators meet or exceed industry general standards:
| Parameter Item | Accuracy Index |
|---|---|
| Spline equalization error | ≤ 0.02 mm |
| Spline symmetry | ≤ 0.02 mm |
| The coaxiality of the spline alignment axis | ≤ 0.02~0.03 mm |
| Minor diameter d surface roughness | Ra ≤ 0.8 μm |
| Major diameter D surface roughness | Ra ≤ 3.2~6.3 μm |
In addition to the above standard parameters, we also can customize special specification products according to customer drawing requirements. From module, tooth number to total length and fitting tolerance, personalized customization can be realized to meet special assembly requirements of different equipment. Each batch of products is accompanied by complete material report and accuracy inspection report, making customers purchase with confidence and use with peace of mind.
This product has excellent versatility, not only suitable for medium and low speed heavy equipment, but also applicable to medium and high speed precision transmission scenarios. It can meet transmission requirements of various equipment without additional adaptation adjustment, and has been widely used in many industries.
