Background

In the motor industry, the bearing is widely used, most of the cases are that the bearing is in interference fit with a bearing platform, and the bearing is in clearance fit with a bearing seat, so that the problem in the case is basically that the bearing is detached from the bearing platform; however, in the use environment of the coal mine motor, the outer ring of the bearing is also in a stressed state, all the outer circles and the bearing chamber are also in interference fit, and two problems of disassembling the outer ring and the inner ring of the bearing need to be faced at the moment.

Since the bearing is an important part for providing rotation of the motor, it is important to attach and detach the bearing of the motor. From the structural point of view of the current motor design, the space for bearing disassembly is not available, so that each disassembly is basically destructive, and the integrity of the whole bearing device is seriously affected.

The bearing device is characterized in that a bearing is required to be replaced or repaired by heating when a bearing table of a bearing chamber is required to be removed, the bearing is synchronously heated when the bearing in a built-in bearing sleeve is removed by heating, the bearing can not be removed frequently and the bearing can be removed destructively, the bearing or a bearing seat can be damaged by the method, more cost is required to be additionally added to make up the defect, and the bearing device structure which is convenient to disassemble and assemble is provided according to the defects in the technology.

Disclosure of Invention

The utility model aims at the not enough of above-mentioned prior art, provide a bearing device, on bearing device original basis, increase the position that makes things convenient for the bearing to dismantle, the fail safe nature of spare part when optimizing the bearing and dismantling.

For solving the above technical problem, the utility model discloses a technical scheme is:

the bearing device comprises a bearing seat, a bearing and a main shaft installed by the bearing, wherein open grooves distributed at intervals in the circumferential direction are formed in the inner wall of the bearing seat, and a limiting platform lower than a bearing shoulder is arranged on the main shaft installed by the bearing.

The open grooves are uniformly distributed at intervals along the circumferential direction.

The limiting platforms are uniformly distributed at intervals along the circumferential direction.

The limiting platform is an annular surface with the outer diameter smaller than the bearing retaining shoulder, and a plurality of plane grooves are uniformly arranged on the annular surface at intervals.

The open slot is provided with an arc-shaped slot.

2 to 6 open slots are arranged.

Preferably, the number of the open grooves is 4.

2 to 6 planar grooves are arranged.

Preferably, there are 4 planar slots.

The utility model has the advantages that:

according to the bearing device, on the basis of the original bearing device, an open slot convenient to disassemble and a limiting platform lower than a bearing blocking shoulder are added, so that the bearing is convenient to disassemble, can be added on a shaft and also can be added in a bearing seat, or the bearing and the bearing seat are combined, the bearing is protected from being damaged due to violent disassembly, parts matched with the bearing are protected to be intact, the cost input of the parts is reduced, and the labor intensity of workers is reduced; the scheme is verified to be capable of being put into use in a large scale.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

The utility model provides a bearing device, as shown in figure 1 to figure 6.

Example 1

The bearing device comprises a bearing seat 1, a bearing 3 and a main shaft 4 for mounting the bearing, wherein open grooves 2 which are distributed at intervals in the circumferential direction are formed in the inner wall of the bearing seat.

The open slots 2 are uniformly distributed at intervals along the circumferential direction, the open slots 2 are arc-shaped slots, and preferably, 2 to 6 open slots are arranged.

When the bearing 3 is in the bearing seat 1 and needs to be taken out, as shown in fig. 2 and 3, the bearing disassembling tool 7 is clamped on the bearing 3 through the open slot 2 on the bearing seat, so as to drive the bearing 3 to move out of the bearing seat 1 stably, and ensure that the bearing seat 1 and the bearing are intact. When the bearing is a cylindrical bearing, the bearing inner ring 34 needs to be taken out first, and the bearing outer ring 33 is pulled out by using the clamping jaws 71 of the bearing disassembling tool 7 through the open grooves 2 on the bearing seat.

Example 2

On the basis of embodiment 1, a main shaft for mounting a bearing is provided with limiting platforms 6 lower than a bearing shoulder, and the limiting platforms 6 are also uniformly distributed at intervals along the circumferential direction, in this embodiment, the limiting platforms 6 are annular surfaces with outer diameters smaller than the bearing shoulder, and a plurality of plane grooves are uniformly arranged on the annular surfaces at intervals, preferably, 2 to 6 plane grooves are arranged. In this embodiment, there are 4 open slots and 4 planar slots.

When a fault occurs and the bearing on the shaft needs to be disassembled, as shown in fig. 4 and 5, the bearing disassembling tool 7 is clamped on the limiting platform 6 of the bearing retaining shoulder, the bearing disassembling tool 7 carries the bearing 3, and the bearing is pulled out from the main shaft 4 mounted on the bearing, so that the bearing can be prevented from being damaged and the main shaft can be prevented from being scratched.

The bearing device is additionally provided with the open slot 2 convenient to disassemble and the limit platform 6 lower than the bearing retaining shoulder on the basis of the original bearing device, so that the bearing can be conveniently disassembled, can be added on the main shaft 4 and also can be added in the bearing seat 1, or the two are both convenient to disassemble and can protect the bearing from being damaged due to violent dismantling, parts matched with the bearing are protected to be intact, the cost investment of the parts is reduced, and the labor intensity of workers is reduced; the scheme is verified to be capable of being put into use in a large scale.
