The Reasons for The Heating of Ball Screws And How To Solve The Heating Problem?

1. Causes of heat generation in ball screws

During high-speed operation, ball screws are prone to heat generation due to factors such as friction, resistance, and external forces. The specific reasons are as follows:

1.1. Poor lubrication: When the lubrication of the ball screw is poor, the friction between the ball screw and the nut will increase, thus generating heat.

1.2. Severe wear: When the ball screw and nut are severely worn, friction increases, causing the ball screw to heat up.

1.3. Bearing wear: If the ball screw bearing wears out, it will increase internal resistance and also easily cause the ball screw to heat up.

1.4. The working environment temperature is high: When operating in a high-temperature environment, the temperature of the ball screw is prone to increase.

2. How to solve the problem of heat generation in ball screws?

2.1. Proper selection of lubricant: When using ball screws, it is crucial to choose the right lubricant. Select an appropriate lubricant based on the working environment and load conditions to reduce friction and heat generation in the ball screws.

2.2. Regularly replace lubricant: The lubricant of the ball screw needs to be replaced regularly to ensure the lubrication effect.

2.3. Improving Bearing Precision: Improving bearing precision can make the operation of ball screws smoother, reducing friction and heat generation.

2.4. Reduce load: Appropriately reducing the load can decrease the operating resistance of the ball screw, thereby reducing the heating phenomenon.

2.5. Adjust the working environment temperature: In high-temperature environments, adding heat sinks or reducing the working environment temperature can effectively lower the temperature of the ball screw.

In summary, to address the problem of heat generation in ball screws, we need to solve it through various measures such as correctly selecting lubricating grease, regularly replacing lubricating grease, improving bearing accuracy, reducing load, and adjusting the working environment temperature.
