Abstract

The utility model relates to a ball bearing with an internally-arranged shaft end. The ball bearing comprises a bearing inner ring and a bearing outer ring, wherein a steel ball is arranged between the bearing inner ring and the bearing outer ring; the width central line of the bearing inner ring is not overlapped with the width central line of the bearing outer ring; one end face of the bearing inner ring is overlapped with one end face of the bearing outer ring; the other end face of the bearing inner ring is at least retracted by 3mm relative to the other end face of the bearing outer ring; a spring chuck for fixing a workpiece is arranged on the end face of one end, which is retracted into the bearing outer ring, of the bearing inner ring; the spring chuck is detachably arranged. According to the ball bearing, the outer diameter of the bearing outer ring is enlarged so that the inner ring and the outer ring are asymmetrically arranged; the spring chuck is fixedly connected with the workpiece so that the ball bearing is convenient to mount in various occasions.

Description

The built-in ball bearing of axle head

Technical field

The utility model relates to a kind of bearing, the built-in ball bearing of especially a kind of off-gauge axle head.

Background technique

The inner ring of existing bearing is identical with the diameter of outer ring, while being therefore mated use with shaft assembly, must piercing into and pass from the other end from one end of bearing; More inapplicable for the stricter occasion of installation conditions at some like this.

Model utility content

The technical problems to be solved in the utility model is: a kind of built-in ball bearing of axle head that can be applicable to various occasions is provided.

The utility model solves the technological scheme that its technical problem adopts: the built-in ball bearing of a kind of axle head, comprise bearing inner race and bearing outer ring, between described bearing inner race and bearing outer ring, be provided with steel ball, the width centreline of described bearing inner race does not overlap with the width centreline of bearing outer ring; An end face of described bearing inner race overlaps with an end face of bearing outer ring; At least 3 millimeters of indentations of another end face of the relative bearing outer ring of another end face of bearing inner race; On the end face of one end of described bearing inner race indentation bearing outer ring, be provided with the spring chuck of fixation workpiece; The detachable setting of described spring chuck.

Further, to enter bearing in order holding with blocks dust, between bearing inner race described in the utility model and bearing outer ring, to be provided with sealing cover, described sealing cover bottom has three contact lips; Three described contact lips all equate with bearing inner race close contact and closeness of contact; Described sealing cover is made up of rubber parts and skeleton, and described rubber parts and skeleton bond together.

Further say, bearing inner race described in the utility model is connected with workpiece by spring chuck; Described spring chuck is U-shaped.

The beneficial effects of the utility model are, have solved the defect existing in background technique, have strengthened the external diameter of bearing outer ring, make the asymmetric setting of inside and outside circle, fix by spring chuck and workpiece, are convenient to the installation of various occasions.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of preferred embodiment of the present utility model;

In figure: 1, bearing outer ring; 2, bearing inner race; 3, steel ball; 4, sealing cover; 41, rubber parts; 42, skeleton; 5, contact lip; 6, spring chuck; 7, workpiece.

Embodiment

With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

The built-in ball bearing of a kind of axle head as shown in Figure 1, comprises bearing inner race 2 and bearing outer ring 1, between bearing inner race 2 and bearing outer ring 1, is provided with steel ball 3, between bearing inner race 2 and bearing outer ring 1, is provided with sealing cover 4, and sealing cover 4 bottoms have three contact lips 5; Three contact lips 5 all equate with bearing inner race 2 close contacts and closeness of contact; Sealing cover 4 is made up of rubber parts 41 and skeleton 42, and rubber parts 41 and skeleton 42 bond together.

The width centreline of bearing inner race 2 does not overlap with the width centreline of bearing outer ring 1; An end face of bearing inner race 2 overlaps with an end face of bearing outer ring 1; At least 3 millimeters of indentations of another end face of the relative bearing outer ring 1 of another end face of bearing inner race 2; On the end face of one end of bearing inner race indentation bearing outer ring, be provided with the spring chuck 6 of fixation workpiece; The detachable setting of spring chuck; Bearing inner race is connected with workpiece 7 by spring chuck; Described spring chuck is U-shaped.

The utility model is nonstandard bearing, and when work, one end of workpiece must have the bayonet socket matching with spring chuck, and bearing is placed on workpiece, by bayonet socket and dop clamping with fixation workpiece.

What in above specification, describe is embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field read after specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence and the scope of model utility.
