Description

Technical Field

[0001] The utility model relates to the field of couplings, in particular to a coupling installation and disassembly tool. Background Art

[0002] Couplings, also known as couplings, are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they rotate together to transmit torque. They play the role of connection, buffering, vibration reduction and improving the dynamic performance of the shaft system. There are many types of couplings. According to the relative position of the two connected shafts and the change of their position, they can be divided into:

[0003] ① Fixed coupling: Mainly used in places where two shafts require strict alignment and no relative displacement occurs during operation. The structure is generally simple and easy to manufacture, and the instantaneous speed of the two shafts is the same. There are mainly flange couplings, sleeve couplings, and clamp couplings.

[0004] ② Removable coupling: Mainly used in places where there is deflection between two shafts or relative displacement during work. According to the method of compensating displacement, it can be divided into rigid removable coupling and elastic removable coupling.

[0005] Rigid movable couplings use the dynamic connection between the working parts of the coupling to compensate for the mobility in one or several directions, such as tooth couplings (allowing axial displacement), cross groove couplings (used to connect two shafts with very small parallel displacement or angular displacement), universal couplings (used where the two shafts have a large deflection angle or a large angular displacement during operation), gear couplings (allowing comprehensive displacement), chain couplings (allowing radial displacement), etc. Elastic movable couplings (referred to as elastic couplings) use the elastic deformation of elastic elements to compensate for the deflection and displacement of the two shafts. At the same time, elastic elements also have buffering and vibration reduction properties, such as serpentine spring couplings, radial multi-layer leaf spring couplings, elastic ring pin couplings, nylon pin couplings, rubber sleeve couplings, etc. Some couplings have been standardized. When choosing, you should first select the appropriate type according to the work requirements, then calculate the torque and speed according to the diameter of the shaft, then find the applicable model from the relevant manual, and finally make necessary verification calculations for certain key parts.

[0006] The coupling is too standardized, the disassembly steps of the coupling are complicated and difficult to install, and the disassembly and assembly methods of the hydraulic cylinder are complicated and have poor practicality.

[0029] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0030] First embodiment

[0031] Please refer to Figure 1 ,in, Figure 1 This is a schematic structural diagram of a first embodiment of a coupling installation and disassembly tool provided by the present invention. A coupling installation and disassembly tool comprises: an internal gear sleeve assembly 1;

[0032] A long threaded rod 2, wherein the long threaded rod 2 is threadedly engaged with the internal gear sleeve assembly 1;

[0033] A drum-shaped gear sleeve 3, which is arranged on the surface of the inner gear sleeve assembly 1;

[0034] a notched plate 9, the notched plate 9 being sleeved on the long threaded rod 2 and fixedly mounted on the surface of the drum-shaped gear sleeve 3;

[0035] A hollow sleeve 4 is sleeved on one side of the outer surface of the long threaded rod 2. A hollow jacking pipe 5 is sleeved on one side of the outer surface of the long threaded rod 2 and located on the left side of the outer surface of the hollow sleeve 4. A hollow hydraulic cylinder 6 is sleeved on one side of the outer surface of the long threaded rod 2 and located on the left side of the hollow jacking pipe 5. An anti-movement plate 7 is sleeved on the left side of the outer surface of the long threaded rod 2. The long threaded rod 2 is threadedly engaged with the left side of the outer surface of the long threaded rod 2 and is located on the left side of the anti-movement plate 7.

[0036] The anti-loosening bolt 8 is threadedly engaged with the left side of the outer surface of the long threaded rod 2 and is located on the left side of the surface of the anti-loosening plate 7.

[0037] A top plate 13 is fixedly mounted on one side of the outer surface of the hollow sleeve 4 .

[0038] The working principle of the coupling installation and disassembly tool provided by the utility model is as follows:

[0039] During operation, first rotate the threaded end of the long threaded rod 2 and insert it into the shaft of the motor, then install the notched plate 9, hollow sleeve 4, hollow top pipe 5, hollow hydraulic cylinder 6 and anti-movement plate 7 in sequence on the surface of the long threaded rod 2, and thread the anti-loosening bolt 8 into engagement with the surface of the long threaded rod 2 and fit the left side of the outer surface of the hollow hydraulic cylinder 6, so that the anti-movement plate 7 and the top plate 13 are against the hollow hydraulic cylinder 6.

[0040] The annular hydraulic rod of the hollow hydraulic cylinder 6 extends out to push the hollow sleeve 4, the hollow top pipe 5, the notched plate 9 and the drum-shaped gear sleeve 3. Since the long threaded rod 2 and the shaft of the motor are fixed, the drum-shaped gear sleeve 3 is pushed to the designated installation position by the action of the hydraulic cylinder to achieve an interference fit. Oiling is required during the installation process.

[0041] The hollow hydraulic cylinder 6 does not work, and hydraulic oil is injected through the oil filling pipeline to release the internal fit and the drum-shaped gear sleeve 3 is ejected. At this time, due to the assembly effect of the hollow hydraulic cylinder 6 and the long threaded rod 2, the drum-shaped gear sleeve 3 can only be disengaged and will not fly out. A small gap is left between the drum-shaped gear sleeve 3 and the notched plate 9 to provide a buffer for the drum-shaped gear sleeve 3 to pop out.

[0042] Compared with the related art, the coupling installation and disassembly tool provided by the present invention has the following beneficial effects:

The device has a simple structure, strong practicality, and a convenient and simple disassembly and assembly method, thereby improving the convenience and flexibility of the device.
