Problems solved by technology

On the whole, the structure of this case is complicated, there are many small parts and it is not easy to assemble, and because of the design of the parts, it is necessary to load the rolling parts of a steel ball and a steel ball holder between the screw shaft and the fixed seat one by one, so the production man-hour The high cost is not conducive to the reduction of product manufacturing costs, and it is also prone to failures due to the large number of parts
[0004] In addition, in the case of Japanese Patent Laid-Open No. 2001-99257, a plurality of steel balls and a steel ball holder are also provided, and most plastic spacers on the steel ball holder are provided with connecti

Abstract

The invention relates to a ball screw high-speed mute structure which comprises a fixing base, a screw axle, at least two opposite ball ring, a sealing sheet, and an annular sheath. Wherein, said fixing base has a through inner hole in the center; the inner hole has a screw groove; at least a couple of hollow grooves are arranged at the fixing base; the ball ring along the hollow groove is arranged into the inner hole to make the ball rings cover the outer surface of screw axle with full circumference; the ball ring in ellipse shape to avoid jam of ball to realize the mute function in high speed rotation of screw axle.

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 ...
