Description

Technical Field

[0001] The utility model relates to the technical field of bearing and coupling disassembly tools, in particular to a bearing and coupling disassembly combined tool. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. They are an important component in contemporary mechanical equipment. Their main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during transmission. During the installation process, bearings require interference fit with the shaft they match, but bearings need to be removed and replaced with new bearings after a certain period of use.

[0003] The coupling is used to connect two shafts in different mechanisms so that they rotate together to transmit torque. After the coupling is assembled on the shaft and used for a period of time, a tight fit between the coupling and the shaft is likely to occur, making it impossible to remove the coupling from the shaft normally.

[0004] In the existing bearing disassembly technology, large bearings or couplings are usually disassembled by using the following methods: Figure 3 The bearing removal combination tool shown is used in combination with a jack, but this method has the following disadvantages in many cases:

[0005] 1. Due to the influence of the limit working stroke of jacks of different tonnages, the distance between the top bull and the shaft end is relatively long, so the method of adding a support rod is often used;

[0006] 2. When the maintenance personnel operate the jack, they are very close to the support rod. When pulling the jack, the support rod is easily ejected due to the force, which poses a great safety hazard. Utility Model Content

[0007] In view of the above technical problems, the utility model provides a bearing and coupling disassembly combination tool.

[0008] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0009] A bearing and coupling disassembly combined tool, comprising:

[0010] A plurality of groups of positioning grooves are sequentially arranged in the bearing fixing frame from front to back;

[0011] The tooling baffle is vertically arranged in the bearing fixing frame, and its two ends are inserted into any set of positioning grooves;

[0012] The bearing or coupling is clamped in the semicircular notch at the bottom of the front end of the bearing fixing frame, the jack is arranged in the bearing fixing frame, the base and the tooling baffle are pressed against each other, and the telescopic end corresponds to the bearing or coupling.

[0013] The positioning groove is a U-shaped structure.

[0014] A rib plate is arranged on the outer side wall of the positioning groove.

[0015] A lifting lug is arranged on the top of the bearing fixing frame.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model can be adjusted with the structure of jacks of different tonnages through the tooling baffle to ensure that the tool is applicable under the extreme working stroke of the jack, and the bearing and coupling can be disassembled through the telescopic end of the jack to prevent the bearing and coupling from being damaged during the disassembly process.

[0018] 2. The utility model provides a positioning groove on the inner wall of the bearing fixing frame to adjust the distance of the tooling baffle, and the tooling baffle is inserted into the positioning groove according to the actual on-site maintenance situation.

[0019] 3. The utility model can quickly dismantle and replace the bearing without damaging the rotating shaft, and has the characteristics of convenient use, strong practicality and high safety. BRIEF DESCRIPTION OF THE DRAWINGS
