Abstract

The invention provides a diaphragm type lead screw flexible connecting device. The device comprises a lead screw, and an elastic buffer seat sleeving the middle of the lead screw. The elastic buffer seat comprises a shaft sleeve sleeving the outer side of the lead screw, an inner lantern ring sleeving the outer side of the shaft sleeve, and a mounting base sleeving the outer side of the inner lantern ring. An upper elastic sheet group, a lower elastic sheet group and a front elastic sheet group are fixed to the upper, lower and front end surfaces of the mounting base correspondingly. The upperand lower ends of the inner lantern ring are fixedly connected with the upper elastic sheet group and the lower elastic sheet group correspondingly. The front end of the inner lantern ring is fixedlyconnected with the front elastic sheet group. According to the diaphragm type lead screw flexible connecting device, the stability of the lead screw can be improved, a deviation phenomenon occurringin the operating process is corrected, the transmission precision is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of screw rods, in particular to a diaphragm type screw rod flexible coupling device. Background technique [0002] The screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, and vice versa, while being high-precision and reversible. With the characteristics of high performance and high efficiency, screw rods are widely used in various industrial equipment and precision instruments. [0003] The traditional screw is mainly composed of a screw and a nut. Through the tight fit of the screw and the nut, the transmission is stable and the precision is high. However, when the length of the screw is large, the middle part of the screw will move downward The downward bending causes the middle part of the lead screw to shake when it follows the rotation of the moto...
