When circle is installed in outer ring, snap ring has good elastic deformability because of its hatch frame, it is simple to it is installed in outer ring, with
Time, when snap ring arrives outer ring raceway annular groove position, open due to elastic force effect and fall groove location, complete bearing assembling.
As further setting of the present utility model, two ends, described interior raceway bottom surface offer the groove caved in respectively, should
Groove one end is tangent with interior raceway medial wall to be connected, and the groove other end is connected with interior raceway bottom surface by bevel phase.
In said structure, groove structure is offered at two ends, interior raceway bottom surface, can store a part of lubricating oil or grease, for
Rolling element rotates the lubrication providing abundance.
As further setting of the present utility model, one end of described inner ring inner hole wall is prolonged by the transition outwardly of curved arc section
Stretching, the other end of inner ring inner hole wall is chamfering structure.
In said structure, the structure at these inner ring inner hole wall two ends, bearing of being more convenient for is assembled on power transmission shaft.
Using such scheme, outer ring and gear structure are designed to overall structure by this utility model, decrease retainer knot
Structure, substantially reduces the volume of bearing and gear, is effectively improved the utilization rate of gear-box inner space, furthermore, snap ring is again
Well bearing can be played axial limiting effect, solve the axial float problem that bearing occurs at work, and this bearing
Compact conformation, volume are little, be easy to processing and manufacturing.
