Abstract

The utility model provides a single pearl bearing relates to the ball bearing field. This single pearl bearing, including L shape bearing inner race, the 2nd L shape bearing inner race and bearing inner race, L shape bearing inner race's an one end fixedly connected with nylon cushion piece, one side and bearing inner race contact of L shape bearing inner race are kept away from to a nylon cushion piece, the 2nd L shape bearing inner race's the 2nd nylon cushion piece of one end fixedly connected with, one side and bearing inner race contact of the 2nd L shape bearing inner race are kept away from to the 2nd nylon cushion piece, the one end that the 2nd L shape bearing inner race kept away from the 2nd nylon cushion piece extends to L shape bearing inner race's inside and L shape bearing inner race's inner wall contact, the L bearing inner race that appears, the cooperation forms the seal groove between the 2nd L shape bearing inner race and the bearing inner race, the ball groove has been seted up and correspond the position of seal groove in the bearing inner race surface. This single pearl bearing has reduced the processing degree of difficulty, improves the production efficiency of bearing.

Description

A kind of single pearl bearing

Technical field

This utility model is related to ball bearing technical field, specially a kind of single pearl bearing.

Background technology

At present, universal ball bearing construction is by the bearing inner race interference fit close-fitting of fixed component and ball bearing, The bearing outer ring of the ball bearing then axis hole interference fit close-fitting with rotatable parts, such as various wheels, the advantage rolling form is Stabilized structure, pivoting friction resistance is little, long service life, and shortcoming is that ball bearing difficulty of processing is high, and assembling is complicated.

Content of the invention

For the deficiencies in the prior art, this utility model provides a kind of single pearl bearing, solves ball bearing difficult processing Degree is high, assembles challenge.

For realizing object above, this utility model is achieved by the following technical programs: a kind of single pearl bearing, including One l shape bearing outer ring, the 2nd l shape bearing outer ring and bearing inner race, one end of a described l shape bearing outer ring is fixedly connected with One nylon spacer, described first nylon spacer is contacted with bearing inner race away from the side of a l shape bearing outer ring, described 2nd l One end of shape bearing outer ring is fixedly connected with the second nylon spacer, and described second nylon spacer is away from the 2nd l shape bearing outer ring Side is contacted with bearing inner race, and described 2nd l shape bearing outer ring extends to a l shape bearing away from one end of the second nylon spacer The inside of outer ring and the contact internal walls of a l shape bearing outer ring, a described l shape bearing outer ring, the 2nd l shape bearing outer ring and axle Hold and between inner ring, cooperatively form seal groove, the position of described bearing inner race surface and corresponding seal groove offers ball grooves, institute State the ball that is internally provided with of ball grooves, at the axis of described bearing inner race, offer through hole.

Preferably, what a described l shape bearing outer ring, the 2nd l shape bearing outer ring were combined with bearing inner race is a diameter of 20.2mm.

Preferably, the height of described bearing inner race is 9.7mm, and the width of bearing inner race is 12mm, the diameter of described through hole For 6.1mm.

Preferably, a diameter of 4.7mm that a described l shape bearing outer ring is combined with the 2nd l shape bearing outer ring.

This utility model provides a kind of single pearl bearing, and the beneficial effect possessing is: this single pearl bearing, is keeping traditional axle Hold under the situation of advantage, by a l shape bearing outer ring and the 2nd l shape bearing outer ring punching press assembling, instead of traditional outer ring and add This complex assembling processing mode of dust cap, thus reducing difficulty of processing, improves the production efficiency of bearing.

Brief description

Fig. 1 is this utility model structure sectional view；

Fig. 2 is this utility model structure upward view.

In figure: 1 the oneth l shape bearing outer ring, 2 the 2nd l shape bearing outer rings, 3 bearing inner races, 4 first nylon spacers, 5 second Nylon spacer, 6 seal grooves, 7 ball grooves, 8 balls, 9 through holes.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The every other embodiment being obtained, broadly falls into the scope of this utility model protection.

This utility model embodiment provides a kind of single pearl bearing, as shown in Figure 1-2, including a l shape bearing outer ring 1, the Two l shape bearing outer rings 2 and bearing inner race 3, a l shape bearing 1 and the 2nd l shape bearing outer ring 2 are through being stamped and formed out a bearing The entirety of outer ring, a diameter of 20.2mm that a l shape bearing outer ring 1, the 2nd l shape bearing outer ring 2 are combined with bearing inner race 3, the A diameter of 4.7mm that one l shape bearing outer ring 1 is combined with the 2nd l shape bearing outer ring 2, one end of a l shape bearing outer ring 1 is fixed It is connected with the first nylon spacer 4, the size of the first nylon spacer 4 is the end face size of a l shape bearing outer ring 1, the first nylon Pad 4 is contacted with bearing inner race 3 away from the side of a l shape bearing outer ring 1, and one end of the 2nd l shape bearing outer ring 2 is fixedly connected Have the second nylon spacer 5, the size of the second nylon spacer 5 is the size of the 2nd l shape bearing outer ring 2, the second nylon spacer 5 away from The side of the 2nd l shape bearing outer ring 2 is contacted with bearing inner race 3, and the 2nd l shape bearing outer ring 2 is away from one end of the second nylon spacer 5 Extend to the inside of a l shape bearing outer ring 1 and the contact internal walls of a l shape bearing outer ring 1, a l shape bearing outer ring 1, Seal groove 6 is cooperatively formed, seal groove 6 is by a l shape bearing 1 and the 2nd l shape between two l shape bearing outer rings 2 and bearing inner race 3 By be stamped and formed out, the position of bearing inner race 3 surface and corresponding seal groove 6 offers ball grooves 7, ball to bearing outer ring 2 Groove 7 be internally provided with ball 8, ball 8 can roll freely in ball grooves 7, offers through hole at the axis of bearing inner race 3 9, the height of bearing inner race 3 is 9.7mm, and the width of bearing inner race 3 is 12mm, a diameter of 6.1mm of through hole 9.

In sum, this single pearl bearing, under the situation keeping traditional bearing advantage, by a l shape bearing outer ring 1 with 2nd l shape bearing outer ring 2 punching press assembles, and instead of traditional outer ring and adds this complex assembling processing mode of dust cap, from And reduce difficulty of processing, improve the production efficiency of bearing.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
