Description

TECHNICAL FIELD

[0001] The utility model relates to motor technical field, especially a locking mechanism of reduction gearbox turntable. BACKGROUND

[0002] As an important power equipment, motors are widely used in industry, home and transportation fields. Its efficient and reliable characteristics make it a core component in modern mechanical systems. However, with the increasing requirements for motor performance and safety, the existing motor design still has some deficiencies in some aspects, especially in the braking capacity.

[0003] In the application process of the motor, especially in the automation and control system, it is an important technical requirement to quickly stop the rotation of the motor. Most of the current motors continue to run by inertia after power off, which leads to a long time required for stopping. This not only affects the efficiency of the equipment, but also may cause safety hazards in emergency situations. For example, in some application scenarios that require fast response (such as elevators, cranes, etc.), slow stopping of the motor may lead to equipment out of control or personnel injury.

[0004] The existing motor usually lacks effective auxiliary braking structure, which causes the rotating part to continue to rotate for a period of time after the motor is powered off. This is due to the inertia and the limitation of the motor design itself, some motors cannot immediately generate braking force to stop rotation when powered off. This situation is particularly evident in high-speed motors, because their rotational inertia is large, and the brake effect is not obvious, causing delay in stopping time, thus there is a certain safety hazard. SUMMARY

The motor is provided with a locking device installed at the tail of the motor body. The locking shaft assembly in the locking device can quickly reduce the speed of the connected shaft turntable to stop rotation by holding it tightly when the motor body is stopped. Therefore, when the load object on the turntable appears abnormal and needs to be quickly reduced and stopped, the locking device can quickly reduce and brake the output shaft of the motor body, thereby greatly reducing the time from high-speed rotation of the load object to the stopped state, and improving the safety of the motor application.

[0051] Based on this, the reset spring 7041 can always provide a pulling force to the clamping tile 7043, and the pulling force makes the clamping tile 7043 have a movement trend of moving away from the shaft connecting disc 703, so that the clamping tile 7043 is not in contact with the shaft connecting disc 703 in the case of not needing to brake and decelerate, when it is needed to brake and decelerate the shaft connecting disc 703, the driving mechanism controls the clamping tile 7043 to move along the radial direction of the shaft connecting disc 703, so that the clamping groove 7044 of the clamping tile 7043 gradually clamps and brakes the shaft connecting disc 703, when the braking stops, the driving mechanism resets, and the clamping tile 7043 resets to be separated from the shaft connecting disc 703 under the elastic force of the reset spring 7041, and the braking ends.

[0065] Embodiment 3

[0066] This embodiment gives a speed reducer load turntable structure, as shown in Figures 1-5 As shown in the figure, in order to improve the braking effect of the turntable 3, in this embodiment, the edge of the turntable 3 is provided with a brake friction piece 305, which is detachably installed. The brake friction piece 305 protrudes from the edge of the turntable 3, and the two ends of the brake friction piece 305 are transitioned with a circular arc. Such a structure makes the turntable brake device 4 generate friction with the brake friction piece 305 when the turntable brake device 4 brakes the turntable 3, thereby avoiding direct contact with the turntable 3, so that the braking effect of the device is better and the turntable 3 is not worn out, thereby prolonging the service life of the turntable 3. At the same time, since the brake friction piece 305 adopts a detachable installation structure, when the brake friction piece 305 is worn out, it can be replaced independently.

[0067] Specifically, as shown in the figure Figures 1-5 In order to realize the detachable installation of the brake friction piece 305, in this embodiment, the side surface of the turntable 3 is provided with a side cavity 307, and the brake friction piece 305 is inserted and assembled in the side cavity 307. The upper surface of the turntable 3 is provided with an embedding groove 309 at the side cavity 307, and a clamping plate 304 is fixedly installed in the embedding groove 309 by inserting a bolt. The bottom of the clamping plate 304 is inserted into the brake friction piece 305 through a shaft 3040, thereby fixing the brake friction piece 305. When the clamping plate 304 is disassembled, the brake friction piece 305 can be taken out from the side cavity 307, thereby realizing the disassembly and replacement of the brake friction piece 305.

[0068] Specifically, as shown in the figure Figures 2-5 In order to realize the installation of the turntable 3, in this embodiment, the upper surface of the turntable 3 is arrayed with a plurality of fixing screw holes 301, and the positions of the fixing screw holes 301 correspond to the positions of the screw holes on the mounting flange 200 one by one. By inserting a bolt into the fixing screw hole 301, the turntable 3 and the mounting flange 200 can be fixedly connected.

[0069] Specifically, as shown in the figure Figures 2-5 In order to install the load object, in this embodiment, the upper surface of the turntable 3 is also arrayed with a plurality of mounting screw holes 302 corresponding to the load object.

[0070] Specifically, as shown in the figure Figures 3-5As shown in the figure, in order to improve the stability of the fixed load object, the upper surface of the rotating disc 3 is provided with a pressing groove 306, and a pressing ring 303 is movably assembled on the inner wall of the pressing groove 306. A compression spring 3031 is installed between the pressing ring 303 and the bottom surface of the pressing groove 306. The compression spring 3031 can apply an outward pressure to the pressing ring 303. Therefore, when the load object is installed, as the distance between the load object and the rotating disc 3 decreases, the pressing ring 303 can gradually press the load object, so that the entire load object has an outward pressure. This can reduce the loosening of the load object during long-term rotation. It should be noted that the bolt for installing the load object may be loose over time, and the provision of the pressing ring 303 can provide an outward thrust to the load object. Therefore, even if the bolt is slightly loose, the load object can still remain stable.

[0071] Specifically, as shown in the figure, Figures 3-5 In order to prevent the pressing ring 303 from "derailing", the inner side of the pressing ring 303 is provided with a limiting piece 3030, and the inner wall of the pressing groove 306 is provided with a limiting opening 308 at the position of the limiting piece 3030. The limiting piece 3030 is movably clamped in the limiting opening 308. Therefore, no matter how the pressing ring 303 moves, it will not be separated from the pressing groove 306.

[0073] The embodiment provides a detachable reduction gearbox mounting structure, as shown in the figure, Figures 9-11 In order to reduce the maintenance cost of the motor, the reduction gearbox 2 is detachably connected with the motor body 1 through the connecting device 5. When the reduction gearbox 2 or the motor body 1 is abnormally damaged, the reduction gearbox 2 or the motor body 1 can be detached, and then the damaged part can be replaced, without the need to replace the entire motor body 1 and the reduction gearbox 2, thereby reducing the maintenance cost of the motor.

The socket 5000 is provided with a clamping hook 503 capable of clamping the plug-in part 502.

[0075] Specifically, as shown in the figure, Figures 9-11As shown, in order to realize the locking of the plug-in part 502, in the embodiment, a C-shaped groove 5020 is arranged on the side surface of the plug-in part 502, and a tightening spring 504 capable of pushing the clamping hook 503 to move and be clamped in the C-shaped groove 5020 is arranged inside the socket 5000. Such a structure arrangement makes the clamping hook 503 be clamped in the C-shaped groove 5020 under the elastic force of the tightening spring 504 when the plug-in part 502 is inserted into the socket 5000, thereby realizing the locking of the plug-in part 502.

[0076] Specifically, as shown in Figures 9-11 , in order to realize the activity control of the clamping hook 503, thereby facilitating the disassembly of the speed reducer 2, in the embodiment, a dismounting ring 501 is rotatably installed outside the connecting sleeve 500, and one end of the clamping hook 503 is fixedly installed on the inner wall of the dismounting ring 501. Therefore, when the dismounting ring 501 is rotated outside, the position of the clamping hook 503 changes, and when the clamping hook 503 is completely moved out of the inside of the C-shaped groove 5020, the plug-in part 502 can be pulled out and taken off from the socket 5000, that is, the disassembly of the speed reducer 2 can be realized.

[0077] Specifically, as shown in Figures 9-11 , in order to ensure the stable connection of the speed reducer 2 and the motor body 1, in the embodiment, a plurality of plug-in parts 502 are arranged, and the plurality of plug-in parts 502 are arranged in a ring array with the center of the speed reducer 2 as an axis, and the socket 5000 and the clamping hook 503 are one-to-one corresponding to the plug-in part 502.
