Abstract
The utility model discloses a bearing. The bearing comprises an inner ring and an outer ring, wherein a rolling body is arranged between the inner ring and the outer ring; an annular adjusting ring is arranged in the inner ring and is capable of axially moving; the inner diameter of the adjusting ring is equal to the inner diameter of the inner ring; a thread hole is formed in the inner ring; a plurality of adjusting bolts which are uniformly distributed at equal thread pitches penetrate through the thread hole; one end of each adjusting bolt pushes against the adjusting ring; a screw cap is arranged at the other end of each adjusting bolt; pinions are arranged on the screw caps of the adjusting bolts and integrated with the adjusting bolts; large gears meshed with the pinions are arranged on the bearing inner ring; and the adjusting ring which is capable of axially moving and pushes against a shaft shoulder is arranged for limiting the axial movement of the shaft.
Description
Technical field
The utility model relates to a kind of component of machine, and more particularly, it relates to a kind of bearing.
Background technique
For with bearing fit, general axis all can be provided with a shaft shoulder of conflicting with bearing inner race end face, but need to closely cooperate between bearing and bearing support, move axially comparatively difficulty, or because the size error of axle causes bearing inner race end face and the shaft shoulder to be conflicted, cause the easy axial float of axle, the precision of machine cannot be guaranteed.
Model utility content
For prior art exist deficiency, the purpose of this utility model is to provide a kind of bearing, on this bearing, be provided with one and move axially, and with the shaft shoulder conflict regulating ring, the axial motion of restrictive axes.
For achieving the above object, the utility model provides following technological scheme: a kind of bearing, comprise inner ring, outer ring, described inner ring, between outer ring, be provided with rolling element, described inner ring is provided with axially movable annular regulating ring, the internal diameter of described regulating ring equals inner ring internal diameter, described inner ring is provided with tapped hole, in described tapped hole, be equipped with some being uniformly distributed, and the adjusting screw that pitch is equal, described adjusting screw one end and regulating ring are conflicted, the described adjusting screw the other end is provided with nut, the nut of described adjusting screw is provided with small gear, small gear and adjusting screw are integrated, described bearing inner race is provided with the gearwheel engaging with each small gear.
By adopting technique scheme, by regulating axially movable regulating ring, regulating ring and the shaft shoulder are conflicted, the axial motion of restrictive axes improves accuracy of machines, regulating ring is regulated by some adjusting screw, adjusting screw is provided with small gear, gearwheel and some small gears are intermeshing, when rotation gearwheel, the engagement of drive small gear, make the angle of swing of each adjusting screw identical, because the pitch of each adjusting screw is identical, adjusting screw coordinates with the tapped hole on inner ring, when rotation gearwheel, on regulating ring, the axially movable distance of various piece all equates, thereby regulating ring and the shaft shoulder are conflicted, moving axially of restrictive axes, improve the overall precision of machine.
The utility model is further set to: described gearwheel and each small gear are circumscribed, and the maximum diameter of gearwheel is less than outer ring minimum diameter.
By adopting technique scheme, described gearwheel and each small gear are circumscribed, convenient rotation gearwheel, and the maximum diameter of gearwheel is less than outer ring minimum diameter, avoids regulating ring and bearing outer ring to interfere.
The utility model is further set to: described gearwheel is provided with anti-skidding lines away from the circumferential surface of small gear.
By adopting technique scheme, increase the frictional force between staff and gearwheel, convenient rotation, and without by other instruments.
The utility model is further set to: described adjusting screw is 3.
By adopting technique scheme, adjusting screw is 3, can determine a plane at 3, and regulating ring is supported jointly by 3 adjusting screw, and therefore regulating ring can only move axially.
The utility model is further set to: described gearwheel and small gear engagement place are provided with safety cover.
By adopting technique scheme, gearwheel and small gear engagement place are provided with safety cover, avoid the extraneous thing such as dust, impurity to enter gear engagement place.
