Description

Technical Field

[0001] The utility model belongs to the technical field of speed reducer disassembly tooling, and in particular relates to a vertical pressing and disassembly tooling for disassembling a speed reducer shaft. Background Art

[0002] The reducer is an independent component composed of a rigid housing, gear transmission, worm transmission and other components. It is often used as a reduction transmission device between the prime mover and the working machine, and plays the role of matching the speed and transmitting torque between the prime mover and the working machine. When the reducer fails or needs maintenance, it needs to be disassembled for repair and maintenance.

[0003] Some reducer structures are made into two halves for easy installation and disassembly, so that they are easy to disassemble and install without damaging the reducer housing. However, some reducer housings are fully enclosed integral structures, and the shaft inside them needs to be pressed out by pressure. Now, the reducer is generally placed on a platform to directly apply pressure to the shaft. This method of reducing the shaft disassembly easily applies pressure directly to the reducer housing, causing the reducer housing to be crushed and cracked. The reducer housing is expensive, which causes great losses. Therefore, a tooling that can facilitate the removal of the reducer shaft and is not easy to damage the reducer housing is needed to solve this problem. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a vertical pressing and disassembling tool for the reducer shaft. The utility model aims to realize the fast and convenient disassembly of the reducer shaft. The pressure during the shaft disassembly will not be directly pressed on the reducer housing, thereby avoiding the problem of the reducer housing being crushed and fractured.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The vertical pressing and disassembly tool for disassembling the reducer shaft comprises a base, the middle part of the base is hollow, and columns are vertically arranged on the left and right sides of the upper part of the base. A platform for placing the disassembled reducer is supported on the upper part of the base and between the left and right columns. The platform is provided with an axis pressing-out hole that is opposite to the axis on the reducer. A crossbeam is fixedly supported on the upper part of the two columns, and a hydraulic cylinder is fixed on the lower part of the crossbeam. The axis of the hydraulic cylinder is vertically arranged. When disassembling the reducer shaft, the axis pressing-out hole on the platform is coaxial with the hydraulic cylinder and the disassembled shaft on the reducer.

[0007] To further define the above scheme, the base includes a bottom plate, and vertical plates are vertically provided on the left and right sides of the upper part of the bottom plate. Upper flat plates are horizontally fixed on the upper parts of the two vertical plates respectively. The upper surfaces of the two upper flat plates are flush to form a supporting surface for supporting the platform. A space is formed between the vertical plates on both sides and the upper flat plates to accommodate the pressed reducer shaft. The vertical plates are reinforced and connected to the bottom plate and the upper flat plate by reinforcing plate I.

[0008] To further define the above solution, the platform is horizontally placed on the upper part of the two upper plates, the lower part of the platform is supported on both sides by the upper plates, and the platform can be longitudinally moved forward and backward on the upper plates to adjust its position.

[0009] As a further limitation of the above solution, two shaft pressing holes are provided in the middle of the platform.

[0010] To further limit the above solution, the upper part of the hydraulic cylinder is fixedly connected to the crossbeam through a hydraulic cylinder base, and a pressure head is sleeved on the end of the piston rod of the lower part of the hydraulic cylinder.

[0011] As a further limitation of the above solution, the pressure head is made of rubber material.

[0012] As a further limitation of the above solution, the lower part of the column is fixedly connected to the base via a reinforcing plate II, and the upper part of the column is fixedly connected to the base via a reinforcing plate III.

[0013] The advantages of this utility model compared with the prior art:

[0014] 1. This scheme designs a tool for disassembling the reducer shaft of a fully enclosed integral structure. A base is set, the middle of the base is hollow and a space for shaft disassembly is reserved. A platform for placing the reducer is set on the upper part of the base. A hydraulic cylinder is also set on the upper part of the base. When disassembling the reducer shaft, the reducer is placed on the platform so that the shaft pressing hole on the platform is coaxial with the hydraulic cylinder and the shaft to be disassembled on the reducer. The hydraulic cylinder piston rod extends downward to press the reducer shaft downward through the shaft pressing hole to the lower part of the platform. This structure realizes the quick and convenient disassembly of the reducer shaft. The pressure during shaft disassembly will not be directly pressed on the reducer housing, thereby avoiding the problem of the reducer housing being crushed or fractured.

[0015] 2. In this solution, a pressure head is sleeved on the end of the piston rod at the lower part of the hydraulic cylinder, and the pressure head is made of rubber material. During the working process, the pressure head contacts the reducer shaft to avoid wear on the shaft end surface;

[0016] 3. In this solution, the platform is horizontally placed on the upper part of the two bases. The platform can be moved longitudinally and adjusted on the base. Two shaft pressing holes are provided in the middle of the platform. For the reducer with two shafts, the two shafts can correspond to the two shaft pressing holes on the platform. Then, by adjusting the position of the platform, the two shafts can be made to correspond to the hydraulic cylinders respectively, and the shafts can be pressed out in turn to avoid the back and forth movement of the reducer and prevent damage to the reducer caused by multiple movements.
