Description
Technical field
Field of bearings is the utility model is related to, more particularly to a kind of bicycle middle shaft special bearing.
Background technology
Bearing will be used in bicycle connection wheel, the performance of this bearing determines the performance of bicycle, now
Bicycle bearings mostly be conventional deep groove ball bearing, bearing interior space is inadequate, bearing install when can not be to bearing
Axially mounted position is positioned, in-convenience in use.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of bicycle middle shaft special bearing, simple in construction, adopts
Designed with inclined ditch, add the inner space of bearing, there are countersunk head groove, convenient installation positioning in one end of inner ring, and inner ring designs
There is sealing ring, prevent from releasing when bearing from installing.
Technical scheme is used by the utility model solves its technical problem：A kind of bicycle middle shaft special axis is provided
Hold, including outer ring and inner ring, bias is evenly equipped with several balls, the side peace of described ball between described outer ring and inner ring
Equipped with unilateral retainer, the position between described outer ring and inner ring with unilateral retainer homonymy is provided with dust cap, and this is dust-proof
The upper end pointed nose of lid is embedded into the groove on the inside of outer ring, and the lower end outside of described dust cap is disposed with annular groove, institute
Location arrangements of the lateral surface for the inner ring stated close to edge have a circle positioning convex, cross out and stretch on the inside of the positioning convex
An intersegmental gap is left in annular groove and between annular groove, is embedded in side by side on described inner ring madial wall and axial direction is installed
Sealing ring, the endoporus of described inner ring are disposed with a circle countersunk head groove close to one end bead of dust cap.
Preferably, the inside of described dust cap is provided with supporting plate.
Beneficial effect：A kind of bicycle middle shaft special bearing is the utility model is related to, it is simple in construction, designed using inclined ditch,
The inner space of bearing is added, there are countersunk head groove, convenient installation positioning in one end of inner ring, and inner ring is designed with sealing ring, prevents
Released when only bearing is installed.
