Description

Vertical split bearing seat with bushing

Technical Field

The utility model relates to the mechanical manufacturing industry, in particular to a vertical split bearing seat with a bushing.

Background

At present, the vertical split bearing seat is a relatively mature bearing installation mechanical structure, and the country also has corresponding standards. The bearing seat in this structural form is basically manufactured by machine manufacturing enterprises with reference to the national standard. However, once the bearing outer ring of the bearing is rotated relatively in the inner hole of the bearing seat in the use process of the bearing seat in the structural form, when the inner hole of the bearing seat is worn out to cause the larger size, repairing modes such as overlaying, spraying, cladding, brush plating and the like are generally adopted for repairing, but the repairing methods have high technical requirements and relatively complex operation.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the vertical split bearing seat with the bushing, overcomes the defects of the prior art, and has the characteristics of simple structure and simplicity and convenience in bushing replacement.

The technical problems to be solved by the utility model are realized by the following technical scheme:

the vertical split bearing seat with the bushing comprises a bearing seat, wherein a bearing is arranged in an inner hole of the bearing seat and is matched with a rotating shaft on the inner side, and a bearing bushing is further arranged in the inner hole of the bearing seat; the bushing is cylindrical; the outer circle of the bushing is matched with the inner hole of the bearing seat, and the inner hole of the bushing is matched with the rotating shaft.

Preferably, an anti-rotation pin is arranged between the bushing and the bearing seat.

Preferably, the bearing seat comprises a bearing seat upper cover and a bearing seat lower part; the bushing is symmetrical in two halves, including half on the upper inner side of the bearing seat upper cover and half on the lower inner side of the bearing seat.

Preferably, the anti-rotation pin is located directly above the upper half and directly below the lower half of the bushing.

Preferably, the bearing seat is also provided with a mounting hole for fixing the gland of the outer ring of the bearing.

Preferably, the bushing length L is consistent with the bearing housing bore axial length.

Preferably, the bushing is a carbon steel, stainless steel or alloy steel material structure.

Through the technical scheme, the utility model has the following beneficial effects:

1. the bearing bush is designed in an inner hole of a bearing seat for installing a bearing, the bush is in a cylindrical shape, the outer circle of the bush is matched with the inner hole of the bearing seat, the inner hole of the bush is matched with a rotating shaft, two halves are symmetrical, one half is covered on the upper cover of the bearing seat, and the other half is arranged at the lower part of the bearing seat; in order to prevent the bushing from rotating relative to the bearing seat, an anti-rotation pin is arranged between the bushing and the bearing seat. The utility model has simple structure and convenient operation when the bushing is replaced.

2. When the bearing is in operation, the bearing outer ring and the bearing seat relatively rotate to cause the increase of the abrasion size of the inner hole of the bearing seat, the bush can be directly replaced without more complicated repair of the inner hole of the bearing seat, and the novel bush structure is also easy to process and manufacture.

FIG. 2 is a cross-sectional view of a vertical split bearing housing with bushings

Numbering in the figures: the device comprises a 1-bearing seat upper cover fastening screw, a 2-bearing seat upper cover, a 3-bearing seat lower part, a 4-bearing, a 5-anti-rotation pin, a 6-rotation shaft, a 7-bearing seat lower part foundation bolt hole, an 8-bearing gland fastening bolt hole, a 9-bearing seat and a 10-bushing

Description of the embodiments

The vertical split bearing seat with the bushing shown in fig. 1 and 2 comprises a bearing seat upper cover fastening screw 1, a bearing seat upper cover 2, a bearing seat lower part 3, a bearing 4, an anti-rotation pin 5, a rotating shaft 6, a bearing seat lower foundation bolt hole 7, a bearing gland fastening bolt hole 8, a bearing seat 9, a bushing 10 and a bearing seat 9, wherein the bearing seat upper cover 2 and the bearing seat lower part 3.

By designing a bearing bush 10 in the inner bore of the bearing housing 9 in which the bearing 4 is mounted, the bush 10 is of cylindrical construction. The outer circle of the bushing 10 is matched with the inner hole of the bearing seat 9, and the inner hole of the bushing 10 is matched with the rotating shaft 6. And two symmetrical halves, one half is arranged on the upper cover 2 of the bearing seat and the other half is arranged on the lower part 3 of the bearing seat. In order to prevent the bushing 10 from rotating relative to the bearing housing 9, an anti-rotation pin 5 is provided between the bushing 10 and the bearing housing 9.

The fit tolerance of the outer diameter D1 of the bushing 10 with the bearing housing bore and the fit tolerance of the inner diameter D2 with the spindle perform the national relevant standards. The radial thickness h (i.e., D1-D2) is dependent on the bearing socket size. The bearing has larger bearing capacity, and the thickness dimension of the bearing can be properly increased so as to improve the bearing capacity of the bearing. The length L of the bushing 10 is consistent with the axial length of the inner hole of the bearing seat.

The material selected for the bushing 10 must have good bearing capacity and machining performance, and carbon steel, stainless steel, alloy steel, etc. are preferable.

The anti-rotation pin 5 is designed to be positioned directly above the upper half and directly below the lower half of the bushing 10, and the diameter d is appropriately selected according to the size of the radial thickness h of the bushing, and the larger the diameter is, the stronger the anti-rotation capability is. The material is the same as the material of the universal anti-rotation pin.

When the bushing 10 is worn after a certain period of use, the bushing can be directly replaced by a new bushing, and the anti-rotation pin 5 can be not replaced.

The bearing seat 9 is provided with a mounting hole 8 for mounting a bearing outer ring gland which is a common general component.

In the running process of the bearing, when the bearing outer ring and the bearing seat relatively rotate to cause the increase of the abrasion size of the inner hole of the bearing seat, the bushing can be directly replaced without more complicated repair of the inner hole of the bearing seat, and the inner hole is not repaired by means of overlaying, spraying, cladding, brush plating and the like.
