Abstract

The utility model provides an insert bearing with a concentric sleeve. The insert bearing comprises an outer ring, an inner ring, a ball and a handling frame, wherein the inner ring is fixedly connected with a shaft, one end of the inner ring is a small-diameter part and is provided with a plurality of open through grooves, and the small-diameter part is clamped with the concentric sleeve and locked by using a locking screw. According to the insert bearing with the concentric sleeve, the inner ring is arranged on the shaft, the small-diameter part of the inner ring is provided with the axial open through grooves, the concentric sleeve is sleeved on the outer periphery of the inner ring, the concentric sleeve is provided with the locking screw, and the inner diameter of the small-diameter part is reduced with the locking of the locking screw, so that the inner ring is fixed and locked on the shaft; because the small-diameter part is equivalently reduced, the concentricity of the inner ring and the shaft can be ensured, and the surface of the shaft can not be damaged; the outer ring is provided with a stop pin, so that the outer ring can be prevented from rotating; after an oil injection hole is arranged, oil can be conveniently added for lubrication; a sealing ring and a check ring are arranged outside the inner ring and the outer ring, so that the leakage of lubricating oil can be prevented, the long-time lubrication of the bearing can be ensured, and the service life of the bearing can be prolonged.

Description

Band concentric locking collar roller bearing units
Technical field
The utility model relates to bearing manufacturing technology field, is a kind of band concentric locking collar roller bearing units specifically.
Background technique
Along with the fast development of China's industry, machinery increasing, also more industry is higher for the complexity of machinery, correspondingly to connecting the bearing of each mechanism, require also more and more higher.Roller bearing units is a kind of modification of deep groove ball bearing, feature is that its outer ring external diameter surface is sphere, can allocate the effect of playing aligning in the corresponding concave spherical surface of bearing support into, but current roller bearing units is due to defect and the installation question of design, concentricity is difficult to guarantee.
Model utility content
The purpose of this utility model is to provide a kind of band concentric locking collar roller bearing units, to overcome the roller bearing units concentricity of prior art, is difficult to the defect guaranteeing.
The purpose of this utility model realizes by the following technical solutions:
A kind of band concentric locking collar roller bearing units, comprise the ball between outer ring, inner ring and Internal and external cycle and manage frame, described inner ring is fixedly connected with axle, described inner ring one end is minor diameter part, the excircle of described minor diameter part arranges a plurality of opening grooves vertically, symmetrical, on described minor diameter part excircle, is installed with concentric locking collar, described concentric locking collar is the ring set that is provided with opening, at opening, is provided with for locking the lock screw of concentric locking collar.
As the improvement to technique scheme, between described inner ring, outer ring, be provided with seal ring, be positioned at the both sides of retainer and ball.
As the improvement to technique scheme, described seal ring is comprised of steel sheet skeleton and the nitrile rubber being coated on steel sheet skeleton.
As the improvement to technique scheme, between described inner ring, outer ring, be provided with back-up ring, be positioned at the outside of seal ring, be stuck on the excircle of inner ring, with outer ring Spielpassung.
As the improvement to technique scheme, on described outer ring, be provided with stop pin.
As the improvement to technique scheme, the oil groove around outer ring circumference is set on described outer ring, in oil groove, be provided with oilhole, communicate with the cavity between inner ring with outer ring, realize lubricating ball and retainer.
The utility model has the advantage of: band concentric locking collar roller bearing units of the present utility model, inner ring is arranged on axle, the minor diameter part of inner ring is offered axially open groove, is set with concentric locking collar on excircle, has lock screw on concentric locking collar, locking along with lock screw, the internal diameter of the minor diameter part of inner ring diminishes thereupon, thereby inner ring is locked on axle, because diminishing of minor diameter part is that equivalent diminishes, therefore the concentricity of inner ring and axle can be guaranteed, and axle surface can not be destroyed.On outer ring, be provided with stop pin, can prevent outer ring rotation, arrange after oil hole, can be oily easily, seal ring and back-up ring are set outside inner ring, outer ring, can prevent the leakage of lubricant oil, guarantee the long-time lubricated of bearing, extend the working life of bearing.
