Ball screw is a commonly used mechanical transmission element, which is widely used in aerospace, military industry, automobile, robot and other fields. In practical application, the wear resistance of ball screw is very important.
1. Material selection: the material selection of ball screw has an important influence on its wear resistance. Generally speaking, materials with high hardness and good wear resistance can improve the wear resistance of ball screws. Commonly used materials are chrome steel, stainless steel, high speed steel, etc.
2. Lubrication mode and lubricant: the choice of lubrication mode and lubricant will also affect the wear resistance of the ball screw. Generally speaking, the lubrication mode and lubricant should be selected according to the use environment and requirements of ball screw. For example, under the conditions of high temperature and high speed, oil-gas lubrication is often used, and high temperature and high speed lubricating oil is selected.
3. Working environment: the working environment of the ball screw also has an important influence on its wear resistance. For example, in harsh environments such as high temperature, high pressure and corrosion, its wear resistance will be affected.
In addition, the wear resistance of ball screw is also closely related to its application field. For example, in high-speed mechanical equipment, the wear resistance of ball screw is required to be higher, because high-speed operation will aggravate the wear between ball and raceway. In high-load mechanical equipment, the wear resistance of ball screw is also very important, because high load will increase the contact stress between ball and raceway and accelerate wear.
