Description

Technical Field

[0001] The present application relates to the field of overhaul and emergency repair operations, and in particular to a connection structure for quickly repairing a gear coupling after teeth are broken. Background Art

[0002] There are many gear couplings distributed in the production lines of the cold rolling operation department: mainly high-speed shaft couplings connecting the motor and the reducer, low-speed shaft couplings connecting the reducer and the actuator, unwinding machines, rolling mills, tension rollers and other equipment are all covered. In the more than 10 years since the cold rolling department was put into production, there have been many accidents of gear couplings breaking due to lubrication and alignment problems. Since the actuator or reducer needs to be removed as a whole, and there is a large interference fit between the inner gear sleeve and the shaft of the coupling, it takes a long time to disassemble and assemble the gear head during the processing process. Generally, the entire accident takes about 10-12 hours, which has an extremely bad impact and seriously restricts the production rhythm of the production line. Therefore, we proposed a connection structure for quick repair of gear couplings after breaking. Utility Model Content

[0024] like Figure 1 As shown, the embodiment of the present application provides a connection structure for quickly repairing a gear coupling after teeth are punched, comprising:

[0025] An outer gear ring 2, wherein the outer side of the outer gear ring 2 is symmetrically provided with a first through groove 3, and the first through groove 3 is provided on the outer side of the inner gear sleeve 5;

[0026] The positioning block 4 is placed inside the first through groove 3 , and a second through groove 6 is provided in the middle of the positioning block 4 . The end surface of the positioning block 4 close to the inner gear sleeve 5 is welded to the outer side of the inner gear sleeve 5 .

[0027] like Figure 1 As shown, the second through groove 6 is a welding opening, and the inner side of the second through groove 6 is welded to the outer side of the inner gear sleeve 5 .

[0028] The second through slot 6 can be formed in any shape.

[0029] Specifically, the inner wall of the second through groove 6 is welded to the outer side of the inner gear sleeve 5 .

[0030] like Figure 1 As shown, a reinforcing block 7 is welded in the middle of the second through groove 6 , and the end surface of the reinforcing block 7 close to the inner gear sleeve 5 is welded to the outer side of the inner gear sleeve 5 .

[0031] Specifically, the reinforcing block 7 is used to strengthen the welding strength between the positioning block 4 and the inner gear sleeve 5 .

[0032] like Figure 1 As shown: the shape of the first through groove 3 can be opened into any shape.

[0033] Specifically, the first through groove 3 can be circular, rectangular, polygonal, etc.

[0034] like Figure 1 As shown, the positioning block 4 is set to a corresponding shape according to the shape of the first through slot 3 , and the outer shape of the positioning block 4 is the same as the shape of the first through slot 3 .

[0035] Specifically, the positioning block 4 plays the role of transmitting torque, and usually adopts a large nut structure, because nuts are very common in factories, and the round hole in the middle does not need to be processed separately, so it is very convenient to obtain materials.

[0036] like Figure 1 As shown: the inner gear sleeve 5 is provided for meshing inside the outer gear ring 2.

[0037] The outer gear ring 2 and the inner gear sleeve 5 form a transmission structure of the gear coupling 1 .

[0038] Specifically, under normal conditions, the outer gear ring 2 and the inner gear sleeve 5 transmit torque through gear transmission.

[0039] When the equipment is being repaired, the inner gear sleeve 5 and the outer gear ring 2 of the gear coupling cannot transmit torque after being toothed. Since the actuator or reducer needs to be removed as a whole, and there is a large interference fit between the inner gear sleeve 5 of the coupling and the shaft, it takes a long time to disassemble and assemble the gear head during the treatment process. Generally, the entire accident takes about 10-12 hours. Without disassembling the inner gear sleeve 5, prepare two positioning blocks 4 of appropriate size, use gas cutting to cut two first through grooves 3 (slightly larger than the size of the positioning blocks 4) at the relative position of the outer gear ring 2, put the two positioning blocks 4 into the first through grooves 3, and weld the inner surface of the second through groove 6 in the middle of the positioning block 4 to the inner gear sleeve 5. In this way, the inner gear sleeve 5 and the outer gear ring 2 of the coupling can be connected together to transmit torque, and this method only takes 1-2 hours to complete;

[0040] In order to enhance the welding strength between the positioning block 4 and the inner gear sleeve 5 , a reinforcing block 7 may be welded inside the second through groove 6 , and then the end surface of the reinforcing block 7 close to the outer side of the inner gear sleeve 5 may be welded to the outer side of the inner gear sleeve 5 .

[0041] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
