High-precision rotary splines ensure precise, smooth transmission, which improves equipment performance and efficiency. In the need for high-precision transmission, such as machine tools, aerospace and other fields, precision has become the key factor that determines success or failure, so what are the factors that affect the accuracy of rotary splines?
1. Manufacturing accuracy: Errors generated in the manufacturing process, such as heat treatment deformation, grinding burns, etc., may lead to the reduction of the accuracy of the spline;In addition, factors such as abrasion, corrosion, and improper assembly during use may also affect the accuracy of the spline.
2. Materials: material properties such as hardness, wear resistance, and fatigue strength will affect the service life and accuracy retention ability of splines, for example, materials with high hardness have better wear resistance and corrosion resistance, but they may also be more prone to cracking;Therefore, choosing the right material is an important factor to improve the accuracy of rotary splines.
3. Heat treatment process: The heat treatment process can change the internal structure of the material, thereby improving the mechanical properties of the material, and the correct heat treatment process can significantly improve the accuracy and service life of the rotary spline.
4. Errors in the process of processing and assembly: vibration and tool wear in the cutting process may lead to the reduction of the accuracy of the spline, and in the assembly process, if the shaft and the hole are not properly matched, it may also affect the service life and transmission accuracy of the spline.
5. Use environment: high temperature, low temperature, humidity, corrosion and other harsh environmental factors may lead to the decline of the material performance of the spline, thereby affecting its accuracy and service life.
To sum up, in order to improve the accuracy and service life of the rotary spline, it is necessary to comprehensively consider the above factors, and take corresponding measures to reduce the error and protect the rotary spline to ensure the service life and efficient production
