It achieves the conversion of different speeds and torques through the internal gear transmission system. Gearboxes are widely used in industrial and mechanical applications to meet the speed and torque requirements of different mechanical equipment. In engineering applications, gearboxes usually need to be connected between the driving device (such as an electric motor) and the driven device (such as mechanical equipment). This connection needs to take into account factors such as axial alignment, axial expansion and contraction, and torque transmission between the gearbox and other equipment to ensure the reliability and efficiency of the system.

However, when the shaft is fixed to the coupling, bolts and screws are mostly used to limit the shaft, so that the shaft can stably drive the coupling. However, in the actual use process, the tools required to disassemble the shaft are too cumbersome, which increases time and labor costs. Therefore, a coupling for a reducer is proposed to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The outer wall of the connecting shell 1 is provided with a plurality of pads 8, and the outside of each two fixed rods 4 and the movable rod 6 are movably connected with a plurality of connecting plates 9, and the connecting plates 9 can move slightly along the movable rod 6 to provide a flexible connection, and the external thread of the fixed rod 4 is connected with a nut 5, and the fixed rod 4 is limited by the nut 5, and the outer walls of the plurality of pads 8 are respectively fitted with the inner walls of the nut 1 5 and the nut 2 7, and the pads 8 can make the nut 1 5 and the nut 2 7 be installed more tightly, and another connecting shell 1 is provided with a plurality of slot holes 10 on the outside, and one end of the movable rod 6 is movably connected to the inner wall of the slot hole 10.

[0033] refer to Figure 2 and Figure 4 A sliding rod 11 is slidably connected to the top of the connecting shell 1. The outer side of the sliding rod 11 is engaged with the through hole of the rotating shaft 2. The sliding rod 11 limits the rotating shaft 2 to prevent the rotating shaft 2 from sliding out. The adjacent sides of the two sliding rods 11 are rotatably connected to a rotating rod 12. The movement of the sliding rod 11 can drive the rotating rod 12 to rotate. The other end of the rotating rod 12 is rotatably connected to a sliding block 13, which can push the sliding block 13 to move when the rotating rod 12 rotates.

[0034] The outside of the sliding block 13 is slidably connected to the inner wall of the connecting shell 1, and the inner wall of the connecting shell 1 is fixedly connected with a limiting rod 14. The through hole of the sliding block 13 is slidably connected to the outside of the limiting rod 14, so that the sliding block 13 can be more stable when sliding. The outside of the limiting rod 14 is sleeved with a spring 15, and one end of the limiting rod 14 is fixedly connected to a limiting block 16. One end of the spring 15 is fixedly connected to an inner wall of one side of the connecting shell 1, and the other end of the spring 15 is fixedly connected to one side of the sliding block 13.

The outside of the rotating shaft 2 is fixedly connected with a snap plate 17, and the outside of the snap plate 17 is slidably connected to the inner wall of the connecting shell 1, so that the rotating shaft 2 will be snapped with the connecting shell 1 through the snap plate 17 to prevent the rotating shaft 2 from moving the connecting shell 1 during rotation.

[0035] Working principle: In daily use, the sliding rod 11 engages the rotating shaft 2, so that the rotating shaft 2 can be positioned to prevent the rotating shaft 2 from slipping off the inner wall of the connecting shell 1, and during use, the fixing rod 4 will move the inner wall of the movable slot 10, so that when encountering an impact, it can drive the connecting plate 9 to move, so that it can automatically adapt, provide flexible support, and better adapt to the device. When it is necessary to disassemble the rotating shaft 2, the sliding rod 11 is pulled, and the rotating rod 12 can be driven to rotate under the pulling of the sliding rod 11. The rotation of the rotating rod 12 can drive the sliding block 13 to slide on the outside of the limiting rod 14, thereby squeezing the spring 15 so that the spring 15 is deformed to generate elastic potential energy. At this time, the sliding rod 11 can withdraw from the through hole of the rotating shaft 2, so that the rotating shaft 2 can be slid out from the side of the connecting shell 1 to complete the disassembly. When installation is required, the rotating shaft 2 is inserted into the side of the connecting shell 1, and then the sliding rod 11 is inserted into the through hole of the rotating shaft 2, thereby limiting the rotating shaft 2 and preventing the rotating shaft 2 from slipping out to complete the installation.
