The ball screw is a key component commonly used in mechanical transmission systems, which can transform rotary motion into linear motion and has the characteristics of high precision, high rigidity and high efficiency. However, in the long-term working process, some common faults may occur in the ball screw, which may affect its performance and life. This paper will analyze the common faults of ball screw in detail and provide corresponding solutions to help readers better understand and deal with these problems.
Ball screw is difficult to rotate
1. Failure: The ball screw is difficult to rotate, and it needs a large force to rotate.
2. Possible causes and solutions
-The environment around the ball screw is dirty: clean the outer surface of the ball screw and the surrounding environment.
-Poor or excessive lubrication of ball screw: check the lubrication of ball screw and add proper amount of lubricant as required.
-The ball screw is overloaded: check whether the load exceeds the bearing capacity of the ball screw and reduce the load appropriately.
Excessive vibration or noise of ball screw
1. Malfunction: The ball screw produces obvious vibration or noise during operation.
2. Possible causes and solutions
-Instability of ball screw installation: re-adjust the installation position and fixing method of ball screw to ensure its stability.
-Excessive wear of ball screw: Check the wear of ball screw and replace worn parts if necessary.
-Poor lubrication of ball screw: check the lubrication of ball screw, re-lubricate or replace lubricant.
Ball screw wandering or stuck
1. Malfunction: The ball screw is wandering or stuck during operation, which affects the working accuracy and stability.
2. Possible causes and solutions
-Uneven load of ball screw: check the load distribution and adjust the load appropriately to make it evenly distributed on the ball screw.
-Insufficient support rigidity of ball screw: check the support structure and support rigidity of ball screw and reinforce it if necessary.
-Wear or damage of ball screw: check the wear of ball screw parts, and replace the worn parts in time if necessary.
Ball screw leaks oil or leaks oil
1. Fault manifestations: Oil stains or oil drops appear on the surface of the ball screw, indicating that there is oil leakage or oil leakage.
2. Possible causes and solutions
-Poor sealing of the ball screw: check the sealing condition of the ball screw to ensure that the seal is intact.
-Excessive lubricant for ball screw: check the lubricant supply in the lubrication system and add lubricant in an appropriate amount.
-Damage of ball screw parts: Check the wear of ball screw parts, and replace the damaged parts in time if necessary.
Excessive axial clearance of ball screw
1. Malfunction: There is obvious axial clearance during the operation of the ball screw, which affects the working accuracy.
2. Possible causes and solutions
-Insufficient preload of ball screw: Adjust the preload of ball screw to ensure proper axial clearance.
-Damage of ball screw parts: Check the wear of ball screw parts and replace the damaged parts if necessary.
