Description

technical field

[0001] The present invention relates to a high-speed silent structure of a ball screw, especially to a ball screw designed to install and assemble its rolling steel balls, so that when the screw shaft rotates, especially under high-speed rotation, the rolling steel balls will not generate friction and impact The noise makes the assembly convenience and quietness greatly improved. Background technique

[0002] According to the structure design of the ball screw, in order to prevent the metal steel balls from colliding with each other when the steel balls made of metal roll in the spiral groove on the screw shaft, in the known technology, it is filled between the two metal steel balls There are plastic spacers to avoid the sound of metal impact.

[0003] Therefore, in the case of Japanese Patent Laid-Open No. 2000-355278, the designer invented a device for the ball screw to avoid noise. In the design of this case, a steel ball retainer is provided. The sheet ...
