Sectional rolling body type ringless bearing structure

Abstract

The invention discloses a sectional rolling body type ringless bearing structure, which comprises a retainer and a rolling body, wherein multiple continuous rolling needle grooves are formed in the retainer, the rolling body is arranged in the rolling needle grooves and composed of multiple connected rolling structures. Compared with the prior art, a rolling needle body in the ringless bearing is arranged in a sectional manner; through the structure, the pressure can be effectively shared by multiple small rolling needles; clearances among the small rolling needles can be used for containing dust in the mechanical structure to prevent the dust from polluting other devices.

Description

technical field [0001] The invention relates to a rolling element structure without inner and outer ring bearings, in particular to a segmented rolling element type ringless bearing structure. Background technique [0002] The use of ringless bearings is often more precise. Ringless bearings are a kind of movable bearings without outer rings and inner rings. They often directly contact other mechanical parts, wear more, and are easier to damage. They often rotate under greater pressure. This kind of bearing only uses the cage in the ordinary bearing as a bracket to fix the needle roller. Therefore, the needle roller is exposed and directly in contact with other mechanical parts. During long-term work, it will be contaminated with sundries and dust in many equipment. , causing wear and damage to mechanical parts. [0003] In the past, the long-term work of this kind of bearing in this environment will increase the wear and tear, and scratches or bad pits will appear on...

[0002] The use of ringless bearings is often more precise. Ringless bearings are a kind of movable bearings without outer rings and inner rings. They often directly contact other mechanical parts, wear more, and are easier to damage. They often rotate under greater pressure. This kind of bearing only uses the cage in the ordinary bearing as a bracket to fix the needle roller. Therefore, the needle roller is exposed and directly in contact with other mechanical parts. During long-term work, it will be contaminated with sundries and dust in many equipment. , causing wear and damage to mechanical parts

[0003] In the past, the long-term work of this kind of bearing in this environment will increase the wear and tear, and scratches or bad pits will appear on the surface of the outer wall of the needle roller. These scratches or bad pits are more likely to be mixed with sundries. Stuck or even wears out other mechanical parts
