Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bearing disassembly, and particularly relates to a convenient device for quickly disassembling a bearing. Background Technique
[0002] During the overhaul process, when disassembling the bearings of a fan or a motor, under the condition that the protective measures are in place, the knocking method, the pushing method or the hot disassembly method is usually adopted to disassemble the bearing from the bearing seat. These traditional disassembly methods not only have problems such as long operation cycle, high risk coefficient and large cost investment, but also have the situations of high labor intensity of maintenance personnel, low work efficiency, inflexible operation and being very uneconomical and inconvenient, which do not meet the requirements of modern efficient and rapid operation. Content of the Utility Model
[0003] The purpose of the utility model is to provide a convenient device for quickly disassembling a bearing, so as to solve the problems of long operation cycle and low work efficiency existing in the traditional bearing disassembly method.
[0004] The technical solution of the utility model is: a convenient device for quickly disassembling a bearing, which includes a top cover and a positioning member. A through hole is provided on the top cover. A jack is sleeved below the top cover. Positioning columns are symmetrically arranged on both sides of the top cover. The positioning member is in an inverted L shape. The straight sections of the two positioning members face each other inward. The jack push end passes through the through hole and is between the two positioning members. An arc-shaped groove is provided at the end of the straight section of the positioning member. A connecting block is connected to the vertical section of the positioning member. The connecting block is slidably sleeved on the positioning column. Limit nuts are provided on both sides of the connecting block.
[0005] As a further improvement of the utility model, a base is connected below the top cover through a plurality of connecting rods. The plurality of connecting rods are distributed at a certain gap. The jack is arranged inside the connecting rods. The bottom of the jack abuts against the upper surface of the base.
[0006] As a further improvement of the utility model, wear-resistant pads are respectively provided on the inner wall of the groove and the end surface of the jack push end.
[0007] The beneficial effects of the utility model are as follows: Aiming at the inconvenient operation, high risk and long cycle in the traditional method of disassembling bearings, the utility model provides a bearing disassembly device with simple structure, convenient operation, high work efficiency, low labor intensity and high safety level. By using the utility model, safety hazards such as mechanical injuries and fires at the overhaul site can be avoided. At the same time, it is not necessary to consume a large amount of manpower, material resources and financial resources. Only two or even one worker can complete the work of bearing disassembly in a short time. It is practical, convenient, economical and efficient.
[0008] The utility model has a simple and ingenious structure, is easy to adjust, practical, convenient, economic and efficient; the operation time is short and the work efficiency is high; it does not require too many maintenance personnel to operate, with less cost investment and low labor intensity of personnel; it does not use the traditional hot disassembly method, avoids hot work operations, reduces the operation safety risk, and effectively improves the work efficiency of bearing disassembly.

Detailed Description of the Preferred Embodiment
[0012] The following further details the present utility model in conjunction with the accompanying drawings and specific embodiments.
[0013] As Figure 1 shown, a convenient device for quickly disassembling a bearing includes a top cover 1 and a positioning member 2. A through hole 11 is provided on the top cover 1. A jack 3 is sleeved below the top cover 1. Positioning columns 12 are symmetrically arranged on both sides of the top cover 1. The positioning member 2 is in an inverted L shape, and the straight sections of the two positioning members 2 face each other inward. The pushing end of the jack 3 passes through the through hole 11 and is between the two positioning members 2. An arc-shaped groove 22 is provided at the end of the straight section of the positioning member 2. A connecting block 21 is connected to the vertical section of the positioning member 2. The connecting block 21 is slidably sleeved on the positioning column 12, and limit nuts 13 are provided on both sides of the connecting block 21.
[0014] A base 15 is connected below the top cover 1 through a plurality of connecting rods 14. The plurality of connecting rods 14 are distributed at a certain gap. The jack 3 is arranged inside the connecting rods 14, and the bottom of the jack 3 abuts against the upper surface of the base 15; wear-resistant pads 23 are respectively provided on the inner wall of the groove 22 and the end surface of the pushing end of the jack 3.
[0015] As Figure 2As shown, the jack 3 is placed in a fixed bracket composed of a top cover 1, a connecting rod 14 and a base 15. The gap between the connecting rods 14 facilitates the operation of the jack 3, effectively improving the stability and convenience of use; two inverted L-shaped positioning members 2 arranged inwardly and opposite to each other form a puller structure, and the limiting nut 13 is loosened to move the positioning member 2 toward the outside of the positioning column 12, so that the bearing 4 is placed between the two positioning members 2, and then the positioning member 2 is moved toward the inside of the positioning column 12, so that the groove 22 fits with the outer wall of the bearing 4, and then the limiting nut 13 is tightened. The limiting nut 13 improves the stability of the positioning member 2 and prevents the positioning member 2 from slipping off the positioning column 12, thereby increasing reliability.
[0016] By pressing the jack 3, the pushing end of the jack 3 is pushed out from the through hole 11, and then the end of the bearing 4 is pushed forward. The circumferential size of the pushing end of the jack 3 is smaller than the circumferential size of the bearing 4, so that the bearing 4 can be continuously pushed out of the bearing seat 5, thereby achieving the purpose of quickly disassembling the bearing 4. The wear-resistant pad 23 at the pushing end of the jack 3 and the inner wall of the groove 22 can avoid wear of the bearing 4 during use, thereby protecting the service life of the components.
