Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motors, namely a coupling and a brake wheel disassembly device, which is used for disassembling the coupling when repairing or replacing the motor. Background Art
[0002] In the prior art, when the motor needs to be overhauled or replaced, the motor or reducer used needs to be replaced due to maintenance or repair. When the coupling is disassembled, the coupling and the brake wheel are connected by multiple connecting bolts arranged along the circumference (see Figure 2 ), that is, the coupling and the brake wheel are connected by reamed hole bolts, the coupling screw hole and the bolt are in transitional fit, the coupling and the bolt fit tightly, and the reamed hole bolts cannot be removed because they are fixed on the brake wheel, which makes it difficult to disassemble the coupling and the brake wheel. After removing the nut, the coupling and the brake wheel are also difficult to disengage, and need to be disassembled by knocking with a hand hammer and a flat shovel, which is not only time-consuming and laborious, but sometimes also causes deformation and damage to the coupling. Utility Model Content
[0003] The purpose of the utility model is to provide a coupling and brake wheel disassembly device with reasonable structure and convenient disassembly in view of the above-mentioned shortcomings.
[0004] The technical solution of the utility model is: a coupling and brake wheel disassembly device, which is characterized in that it includes two semicircular disassembly steel hoops, each of which has warped edges at both ends, and has connecting holes for inserting bolts; a nut is vertically welded in the middle part of each semicircular disassembly steel hoop, and a top screw is horizontally installed on the nut.
[0005] The advantages of the utility model are: it adopts steel hoop for fixing, and realizes the separation of the coupling from the brake wheel through the top screw, and finally completes the disassembly of the coupling; it has reasonable and simple structure, simple operation, safety and reliability, and can replace the use of hand hammer and flat shovel to knock and disassemble the coupling; it can be operated by one person, and is an ideal maintenance tool.
[0006] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a simplified structural diagram of the utility model.
[0008] Figure 2 It is a simplified structural diagram of the utility model in use state. DETAILED DESCRIPTION
[0009] See also Figure 1 , 2The names of the parts are as follows: semicircular disassembly steel hoop 1, warped edge 2, connecting hole 3, bolt 4, nut 5, top screw 6, shaft 7, coupling 8, brake wheel 9, connecting bolt 10, connecting hole 11.
[0010] See also Figure 2 Taking the disassembly of a φ220mm coupling as an example, there is a coupling 8 installed on a shaft 7, and the coupling 8 is connected to the brake wheel 9 through a plurality of connecting bolts 10 arranged along the circumference.
[0011] See also Figure 1 , use 3mm thick steel plate to make two semicircular disassembly steel hoops 1 with a width of 20mm and a diameter of 210mm as shown in the figure. Each semicircular disassembly steel hoop 1 has warped edges 2 at both ends (the warped edges are at right angles to the steel hoop body for easy docking connection), and there are connecting holes 3 for inserting bolts 4 on the warped edges 2. M12mm nuts 5 are welded to the middle parts of the two semicircular disassembly steel hoops 1 to install top screws 6 (which can also be bolts). Use 12 bolts 4 to fix the two semicircular disassembly steel hoops 1 on the coupling 8 to be disassembled. By rotating the two top screws 6, the coupling 8 is withdrawn and separated from the brake wheel 9, so that the coupling 8 can be disassembled.
[0012] Usage: Make a φ220mm coupling and brake wheel disassembly device according to the use requirements. Fix the made φ220mm coupling and brake wheel disassembly device to the φ220mm coupling 8 with nuts 5 through bolts 4, and rotate the two top screws 6 of the φ220mm coupling and brake wheel disassembly device. When the top screws 6 rotate clockwise, the top screws 6 gradually press against the brake wheel 9 on the motor or reducer to disassemble the coupling 8, so that the coupling 8 and the brake wheel 9 are separated.
[0013] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
