Problems solved by technology

This leads to serious failure of the bearing
[0014] U.S. Patent No. 6,352,367 illustrates the disadvantages discussed above by disclosing a spacer between adjacent rolling elements, which spacer is so constructed that if the distance between the balls exceeds the outer dimensions of the spacer, the balls are very Easy to get out of the ball track, which leads to the consequences discussed above

Embodiment Construction

[0034] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, obvious functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail. Throughout the drawings, like elements are provided to be equivalent in structure and function.

[0035] refer to Figure 1-8 , the segmented ball / roller guide according to the invention is generally identified by the reference numeral 10 .

[0036] Figure 1-5Illustrated is a segmented ball / roller guide assembly 100 housing a ball bearing therein. The segmented ball / roller guide 10 of the present invention includes at least one first spacer assembly 12 . Many inventive modifications of the support / guide 10 also include a second spacer 14, although the first spacer assembly 12 can wholly or partially surround rolling elements, such as ball bearings 20, as will be described below. Spacers 12 and 14 are spa...

Abstract

A guide ( 10 ) associated with a linear motion and screw system is configured to at least partially surround one of a plurality of rolling elements ( 20 ) so as to prevent ball-to-ball contact between the one rolling element and adjacent rolling elements during displacement of the rolling element along a circulation ball track.

Description

[0001] Cross-references to related applications [0002] This application is based on US Provisional Application No. 60 / 360,155, filed February 27, 2002, which is hereby fully incorporated by reference. technical field [0003] The present invention relates generally to anti-friction linear motion bearing devices. In particular, the present invention relates to an arrangement utilizing a segmented ball / roller guide for eliminating vibrations caused by ball-ball contact in linear motion bearings. Background technique [0004] It is well known that linear bearings or ball screws play an important role in reducing dynamic and static friction under load compared to sliding bearings or lead screws. Currently, the market offers different types of linear bearings and ball screws. However, they all have a common focus, which is to provide smooth linear or rotary motion by properly controlling the repeated circulation of the ball. [0005] A typical linear rolling bearing assembly...
