What factors affect the motion stability and precision of a ball screw?
Supporting structure: A ball screw requires a supporting structure that is suitable for its diameter and length to ensure stability and precision of motion. The supporting structure should have sufficient rigidity and stability to prevent the ball screw from twisting or vibrating during motion.

How to choose a suitable supporting structure for a ball screw?
Firstly, it is necessary to determine the load that the ball screw needs to bear to choose a suitable supporting structure. The load size is influenced by the application scenario and needs to be chosen according to the actual situation.
What is the close relationship between preloading and accuracy of ball screws
The preload is the pressure applied between the ball screw and the ball to stabilize the ball's movement on the guide rail during assembly.
Detailed explanation of the main reasons for the temperature rise of the ball screw
The temperature rise of the ball screw refers to the phenomenon that the temperature of the ball screw increases during operation due to factors such as friction and rolling between the ball and the guide rail, mechanical vibration, etc.
How to improve the environmental conditions of the ball screw
Improving the environmental conditions for the ball screw can help to reduce its temperature rise and improve its performance.
The difference between planetary roller screw and ball screw
Different structure: The ball screw uses the rolling of balls and guides to transmit force, while the planetary roller screw uses the rolling of planetary rollers and thread nuts to transmit force.
In addition to the accuracy level, what other indicators can be used to evaluate the performance of the ball screw
Load capacity: The load capacity of a ball screw refers to the maximum load it can bear. When selecting a ball screw, it is necessary to choose a suitable specification and model according to the actual load requirements.
How to calculate the critical speed of the ball screw
The critical speed of a ball screw refers to the speed at which it will experience spiral vibration or resonance under a certain load when its speed exceeds the critical speed.
What factors can affect the critical speed constant K in the formula?
Ball screw structure: The structure of the ball screw, such as the number and arrangement of the ball bearings, can affect the critical speed constant.
