Description

Technical Field

[0001] The utility model belongs to the technical field of couplings, and in particular relates to a coupling for engaging a direct-drive torque motor with a reducer. Background Art

[0002] A reducer is an independent component composed of a gear transmission, worm transmission, gears, and worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. A coupling is provided between the transmission shaft of the reducer and the rotating shaft of the motor to connect the two shafts with each other along the axial direction to achieve the purpose of synchronous and smooth rotation of the two shafts.

[0003] After a long period of use, the plum blossom elastic element will wear out, resulting in a gap between the cam and the elastic element, which reduces its buffering performance. At this time, the elastic element needs to be replaced, and the existing coupling is integrally formed during manufacturing. When replacing and repairing, the coupling needs to be dismantled and replaced as a whole, which is inefficient and costly. In addition, when installing the existing coupling, it is necessary to fix the angle of the plum blossom disk and then fit the half couplings on both sides with the plum blossom elastic element, which requires multiple workers to operate simultaneously. For this reason, we propose a coupling for fitting a direct-drive torque motor with a reducer. Utility Model Content

The fixing bolt 34 is fixedly connected to one end of the connecting disk 31 with an insert block 35, and a slot 36 is provided at the other end of the connecting disk 31 opposite to the insert block 35. The modular design of the plum blossom-shaped elastic disk 3 cooperates with its various parts to be fixed by plugging, threading, etc., so that the coupling does not need to be removed as a whole but a single component can be disassembled and replaced, which makes it more efficient. A limit column 14 is provided, and multiple groups of connecting disks 31 are spliced ​​together by the insert blocks 35 and the slots 36 at both ends. After the insert block 35 is inserted into the slot 36, a certain amount of space is still left in the slot 36. The slot 36 can be matched with the limit column 14 to fix the plum blossom-shaped elastic disk 3 on the surface of the motor connection end 1. At this time, the cam 13 and the cam 23 are engaged to complete the installation, thereby reducing the waste of manpower during installation.

[0024] Furthermore, the inner walls of the sleeve 11 and the fixed plate 12 are provided with positioning grooves, and the coupling is connected to the motor output end and the reducer input end through the positioning grooves.

[0025] Furthermore, four groups of protruding claws 13 are evenly arranged around the center of the sleeve 11, and four groups of protruding claws 23 that can engage with the protruding claws 13 are evenly arranged around the center of the sleeve 21. The protruding claws 13 and the protruding claws 23 engage with each other to fix the plum blossom-shaped elastic element 33 therein.

[0026] Furthermore, a groove 1 is provided on the surface of the connecting plate 31 close to the plum blossom-shaped elastic element 33, and the block 32 can be inserted into the groove 1.

[0027] Furthermore, the sum of the lengths of the insert block 35 and the limiting column 14 is equal to the length of the slot 36 , and the size and shape of the limiting column 14 are the same as those of the insert block 35 and the slot 36 .

Power is transmitted by extrusion between the cam and the plum blossom-shaped elastic element 33.

At this time, the cam 13 and the cam 23 are engaged to connect the motor connection end 1 and the reducer connection end 2, and then the reducer connection end 2 is connected to the output end of the reducer through the positioning groove to complete the installation. When the internal components of the plum blossom-shaped elastic disk 3 are worn out due to long-term use and need to be replaced, only the parts that need to be replaced need to be removed without disassembling the entire coupling.
