Effect, avoids the mutual collision between steel ball, is conducive to the extension of steel ball service life；Bearing when in use, utilizes steel ball
Three-point contact type structure enables to the end-play of bearing and radial internal clearance to be controlled, and improves stabilization when bearing working
Property.
The circumferential surface of the outer gear ring offers the annular groove one that cross sectional shape is circular arc type, offers at the inner wall of inner ring
Cross sectional shape is the annular groove two of peach-shaped；The purpose being arranged in this way is: after steel ball is installed in place, may be implemented 3 points of steel ball and connects
The purpose of touching both ensure that the control of bearing end-play to substitute the structure of traditional four point contact ball bearings, can also incite somebody to action
The end-play of bearing controls within limits, to improve stability when bearing working.
The retainer being arranged in inner ring groove is segmentation structure；The purpose being arranged in this way is: can be convenient guarantor
The installment work for holding frame is conducive to retainer and carries out Fast Installation.
The outer radial position of each section of retainer offers equally spaced multiple pocket holes；The purpose being arranged in this way is: pocket
Scope of activities of the hole to limit steel ball guarantees to remain equidistant between two adjacent steel balls, avoids steel-ball collision phenomenon
Generation.
The each section of retainer inner diameter location is equipped with curved opening；The purpose being arranged in this way is: in bearing working, arc
Shape opening forms lubricating oil film with the root of notch position at inner ring outer diameter, to reduce the abrasion of retainer.
The invention has the benefit that the configuration of the present invention is simple, design are rationally, when steel ball can be made to work in bearing,
Three-point contact type structure is formed between inside and outside circle, can axial direction to bearing, radial internal clearance control, reduce friction resistance
Power, and steel ball is accurately guided using the trench structure of retainer, extend the service life of bearing.
