Description

Bearing outer ring structure

Technical Field

The utility model relates to the technical field of bearing outer ring structures, in particular to a bearing outer ring structure.

Background

The end of the motor rotor needs to be supported by a bearing. The whole one section setting that is of current bearing outer wall, the external diameter equals promptly, and the internal diameter also equals, when installing the bearing on the casing, casing extrusion bearing leads to the whole shrink of bearing internal diameter easily, leads to the bearing to hardly install with the axle cooperation.

Therefore, there is a need to provide a new bearing outer ring structure to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a bearing outer ring structure.

The utility model provides a bearing outer ring structure which comprises a ring body, wherein the ring body comprises a thick ring part and a thin ring part, the thick ring part and the thin ring part are of an integrated structure, a first chamfer is arranged at the joint of the outer walls of the thick ring part and the thin ring part, the inner wall of the thick ring part is provided with an arc-shaped mounting hole, and the inner wall of the thin ring part is provided with a matching hole matched with a shaft.

Preferably, the edge of one end of the thick ring part far away from the thin ring part is provided with a second chamfer.

Preferably, the edge of one end of the thin ring part far away from the thick ring part is provided with a third chamfer.

Preferably, the ring body is made of high carbon steel GCr 15.

Preferably, the diameter of each part of the circular arc-shaped mounting hole is larger than that of the matching hole.

Compared with the related art, the bearing outer ring structure provided by the utility model has the following beneficial effects: the big or small segmentation design of bearing outer wall, but thick circle portion and thin circle portion to the fastening after the bearing assembly is ensured to suitable increase thick circle portion position size, and the position of mating holes can effectively be avoided in the big or small segmentation design of bearing outer lane, prevents that the bearing from at the fitting hole shrinkage cavity in the assembling process.

FIG. 1 is a schematic view of the overall structure provided by the present invention;

fig. 2 is a schematic view of a slot structure provided in the present invention.

Reference numbers in the figures: 1. a housing; 11. a thick ring part; 112. a second chamfer; 12. a thin loop part; 121. a mating hole; 122. a third chamfer; 13. and (6) first chamfering.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

Referring to fig. 1-2, the bearing outer ring structure provided by the utility model comprises a ring body 1, wherein the ring body 1 comprises a thick ring part 11 and a thin ring part 12, the thick ring part 11 and the thin ring part 12 are in an integrated structure, a first chamfer 13 is arranged at the joint of the outer walls of the thick ring part 11 and the thin ring part 12, an arc-shaped mounting hole 111 is arranged on the inner wall of the thick ring part 11, and a matching hole 121 matched with a shaft is arranged on the inner wall of the thin ring part 12.

And a second chamfer 112 is arranged at one end edge of the thick ring part 11 far away from the thin ring part 12.

And a third chamfer 122 is arranged at one end edge of the thin ring part 12 far away from the thick ring part 11.

The ring body 1 is made of high-carbon steel GCr15 and has high strength.

The diameters of all parts of the circular arc-shaped mounting hole 111 are larger than the diameter of the matching hole 121, so that when the shaft is mounted, the circular arc-shaped mounting hole 111 is not matched with the shaft, and only the matching hole 121 is matched with the shaft.

The working principle of the bearing outer ring structure provided by the utility model is as follows: the design of bearing outer wall size segmentation, but thick circle portion 11 and thin circle portion 12 to the fastening after the bearing assembly is ensured to suitable 11 position sizes of increase thick circle portion, and the design of bearing outer lane size segmentation can effectively avoid the position of mating holes 121, prevents that the bearing from mating holes 121 shrinkage cavity in the assembling process.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
