Description

technical field

[0001] The invention relates to a mechanical transmission technology, more specifically to a transmission device of a screw and nut mechanism for mechanical transmission. Background technique

[0002] The ball screw pair is the key component of the key function of precision mechanical transmission. In recent years, with the higher and higher requirements for the accuracy of machine tool functions, the requirements for the ball screw pair are also getting higher and higher. The existing ball screw pair mainly includes a screw, a nut, and balls. The balls roll in the cavity formed between the screw raceway and the nut internal thread raceway, so that the linear motion is converted into rotary motion, or the rotary motion is converted into Linear motion, due to the certain error between the screw raceway and the nut internal thread raceway during processing, the ball is in point contact or line contact with the screw raceway and the nut internal thread raceway d...
