Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, 2 and 3, a bearing structure convenient for bearing disassembly includes a pump shaft 8, an angular contact ball bearing 6, a bearing body 2, a shaft sleeve 12, an upper bearing gland 3 and a lower bearing gland 7, wherein the lower bearing gland 7 is sleeved on the pump shaft 8, the shaft sleeve 12 is arranged between the lower bearing gland and the pump shaft and sleeved on the pump shaft, a plurality of first through holes are arranged on the end surface of the lower bearing gland 7, a plurality of first threaded holes corresponding to the first through holes are arranged on the bearing body 2, and a plurality of first screws 9 are inserted into the corresponding first threaded holes through the first through holes to fixedly connect the lower bearing gland 7 with the bearing body 2.
A plurality of limiting gaskets 11 are fixed on the end face of the bearing body 2 on one side of the lower bearing gland 7 through a plurality of second screws 10, all the limiting gaskets 11 are evenly distributed on the end face of the bearing body along the circumference, the plane where each limiting gasket is located is parallel to the end face of the bearing body, one end of each limiting gasket is inserted into the overlapped part of the bearing body and the lower bearing gland to separate the bearing body from the lower bearing gland, and all the second screws are located on the outer side of the circumference of the lower bearing gland.
The end face of the inner side of the lower bearing gland 7 is provided with a sleeve, the inner diameter of the sleeve is equal to the diameter of a round hole of the lower bearing gland, and the outer diameter of the sleeve is smaller than or equal to the outer diameter of the bearing inner ring; one end of the sleeve is fixedly connected with the lower bearing gland, the inner wall of the sleeve is correspondingly connected with the circular hole wall of the lower bearing gland, and the other end of the sleeve faces towards the inner ring of the angular contact ball bearing 6 and is away from the inner ring of the angular contact ball bearing 6 by a certain distance; the sleeve and the lower bearing gland are integrally formed, so that the sleeve and the lower bearing gland are convenient to process and meet the requirement on mechanical strength in the using process. Simultaneously, not only can utilize sleeve structure to dismantle the operation to the bearing at the dismantlement in-process, increased the cooperation length of bearing gland and axle sleeve down moreover, effectively reduce the revealing of lubricating grease.
The thickness of the limiting gasket and the distance from the top end of the first screw to the bottom of the first threaded hole are slightly larger than the distance from the other end of the sleeve to the inner ring of the angular contact ball bearing. The arrangement is that in the pump disassembling process, after the limiting gasket is rotated, in the process of screwing the first screw, the first screw can be further inserted into the first threaded hole, so that the sleeve on the lower bearing gland can prop against the inner ring of the angular contact ball bearing.
Therefore, when the pump runs, the bearing body and the lower bearing gland are separated by the limiting gasket, and meanwhile, the lower bearing gland is not contacted with the angular contact ball bearing; when the pump is disassembled, the position of the limiting gasket is rotated, so that the lower bearing gland is contacted with the angular contact ball bearing, meanwhile, the lower bearing gland props against the inner ring of the angular contact ball bearing, the bearing body, the angular contact ball bearing and the lower bearing gland are just a whole, the angular contact ball bearing can be safely and reliably disassembled from the pump shaft by disassembling the bearing body, and the angular contact ball bearing and the pump shaft cannot be damaged.
The limiting gaskets are four, a second through hole is formed in the center of each limiting gasket, a second threaded hole corresponding to the second through hole is formed in the bearing body, and a second screw penetrates through the second through hole and the corresponding second threaded hole to fixedly connect the limiting gaskets with the bearing body.
The bearing part dismantle step specifically as follows:
1. firstly, removing the upper bearing gland 3 and the fastener thereof;
2. then the round nut 4 and the stop washer 5 are removed, then the first screw 9 and the second screw 10 are unscrewed but not removed, then the limit gasket 11 is moved from the position (shown in figure 2) where the pump runs to the position (shown in figure 3) where the pump is removed, then the first screw 9 is screwed down, so that the lower bearing gland 7 is abutted against the inner ring of the angular contact ball bearing 6 (at this time, the lower bearing gland, the bearing body and the angular contact ball bearing are integrated), and meanwhile, the second screw is screwed down, so that the limit gasket 11 is fixed above the bearing body 2 for next installation;
3. removing a fastening piece between the bearing body 2 and a supporting piece thereof, inserting the jackscrew 1 into an original jackscrew hole on the bearing body 2, and pulling the jackscrew 1 by using a wrench so as to eject the lower bearing gland, the bearing body and the angular contact ball bearing from bottom to top, namely detaching the angular contact ball bearing 6 from the pump shaft 8;
4. finally, the bearing gland 7 is detached, and then the angular contact ball bearing 6 is pushed out of the bearing body 2 by the outer ring of the angular contact ball bearing 6.
The whole disassembly process effectively avoids damage to the bearing and the pump shaft, and the disassembly principle of the bearing is met.
The lower bearing gland of the utility model adopts radial seal, and when the pump operates normally, the lower bearing gland is not contacted with the bearing; when the bearing is disassembled, the installation position of the lower bearing gland arranged on the bearing body is adjusted, so that the lower bearing gland is in contact with the bearing inner ring, the bearing is disassembled from the pump shaft safely and reliably by disassembling the bearing body, and the bearing and the pump shaft are effectively prevented from being damaged.
Finally, it should be noted that the above-mentioned embodiments of the present invention are only examples for illustrating the present invention, and are not limitations to the embodiments of the present invention. Variations and modifications in other variations will occur to those skilled in the art upon reading the foregoing description. Not all embodiments are exhaustive. All obvious changes or variations which are introduced by the technical solution of the present invention are still within the scope of the present invention.
