Ball screw is a key transmission components that converts rotating motion into straight line motion. It is widely used in CNC machine tools, automation equipment, robots, semiconductor equipment, precision measuring instruments and so on. Correct choice of ball screw not only affects the operation accuracy of the equipment, but also directly affects the service life, stability and maintenance cost of the equipment.
1.Defining Load Requirements
Before selecting the ball screw, determine the load the device will bear during use.
Parameters to consider:
Axial load magnitude
Maximum workload
Impact load conditions
Frequency of Load variation frequency
In general, the ball screw with a rated dynamic load higher than the actual working load should be selected to ensure adequate safety and service life.
2.Determine Lead Parameters
Lead refers to the distance the nut moves during a single rotation of the screw.
Large Lead Characteristics:
Running fast
High transmission efficiency
Suitable for high-speed equipment.
Small Lead Characteristics:
High positioning accuracy
Bigger thrust
Suitable for heavy duty, precision control
