Waist type single nut ball screw is a commonly used transmission device with the following advantages:
1. High-efficiency transmission: The waist-shaped single-nut ball screw adopts the ball rolling transmission principle and has higher transmission efficiency than the traditional thread pair. The balls have fewer rolling contact points and less friction, which can reduce energy loss and improve transmission efficiency, thereby achieving higher motion accuracy and speed.
2. High rigidity: During the rolling process, the balls of the ball screw are transmitted through the contact between the raceway and the thread. Compared with the sliding friction of the thread pair, it has higher rigidity. This enables waist-type single-nut ball screws to withstand larger axial loads and higher rigidity requirements, making them suitable for applications requiring high-load movements and precise positioning.
3. High precision: The waist-type single-nut ball screw has small return error and clearance, and can achieve high motion accuracy. There are few contact points between the balls and threads of the ball screw, and the balls roll smoothly, which can reduce friction and wear and improve the accuracy and repeatability of transmission.
4. Long life: Since the ball screw adopts the rolling transmission principle, during the movement, there is only rolling contact between the balls and the raceway. Compared with the sliding friction of the thread pair, it can reduce wear and damage and extend the service life.
To sum up, the waist-type single nut ball screw has the advantages of efficient transmission, high rigidity, high precision and long life, and is widely used in machinery manufacturing, automation equipment, CNC machine tools, industrial robots and other fields.
