Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] This example adopts the flexible part of the compression spring to guide the reversing of the steel ball, thereby forming a flexible steel ball reversing circulation device.

[0028] The structure of the flexible steel ball reversing circulation device mainly includes a steel ball guide spring, a transition block and a positioning ring. The ball reversing cycle enters and exits the hole, and the other end is matched and positioned by the positioning ring, and the transition block is connected with the steel ball guide spring in a circular arc at one end.

[0029] When the flexible steel ball reversing circulation device cooperates with the ball screw, it can ensure that the rotating steel ball smoothly passes through the transition block ...

Abstract

The invention discloses a flexible steel ball reversing circulation device, which includes a steel ball guide spring, a transition block and a positioning ring. The steel ball guide spring is arranged on the spiral spherical groove on the surface of the screw shaft, and one end of the steel ball guide spring is connected to the screw shaft on the screw shaft. The steel ball reversing cycle enters and exits the hole, and the other end is matched and positioned by the positioning ring, and the transition block is connected with one end of the steel ball guide spring in an arc transition. The solution of the present invention innovatively adopts a flexible solution such as a compression spring to guide the reversing of the steel ball, which effectively reduces the impact and noise generated by the steel ball in the high-speed rotation and reversing cycle, thereby effectively solving the problem of the high-speed rotating steel ball in the reversing cycle process. Impact and wear on related parts.

Description

technical field [0001] The invention relates to a ball screw driven worm gear reducer, in particular to a steel ball reversing circulation device in the ball screw driven worm gear reducer. Background technique [0002] With the rapid development of modern automatic industrialization, numerical control devices are more and more widely used in all walks of life. In addition to the electrical control unit, the numerical control device must also be composed of mechanical functional components such as servo motors, ball screws, linear guides, and reducers. [0003] Especially in the field of high-speed and high-precision intelligent numerical control, high-precision, high-torque, and low-cost reducers have become one of the key research and development topics of multinational companies and colleges and universities in the world. Among them, the ball screw driven worm gear reducer developed by China itself has also come out, which subverts the traditional sliding friction struct...
