Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, and more specifically, the utility model relates to a gear locking mechanism for the input shaft of a speed reducer which is convenient to operate. Background Art

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine.

[0003] Power is transmitted into a speed reducer from an input shaft on one side to the inside of the speed reducer housing, and after decelerating it, it is transmitted out through an output shaft. When it is necessary to stop the speed reducer from working, we need to limit the input shaft of the speed reducer. By locking the gear connected to one end of the input shaft, the input shaft can be limited, so as to stop the speed reducer from working. However, the existing gear locking mechanism for the input shaft is relatively inconvenient to operate. For this reason, we propose a gear locking mechanism for the input shaft of a speed reducer which is convenient to operate. Summary of the Utility Model

One end of the input shaft 2 extends outward, and the other end of the input shaft 2 is inserted into the housing 1 and fixed with a bevel gear 7. A rotating shaft 10 is arranged on one side inside the housing 1. Both ends of the rotating shaft 10 are rotatably connected to the side wall of the housing 1 through side bearings. A side bevel gear 11 is fixed on one side of the rotating shaft 10, and the side bevel gear 11 and the bevel gear 7 are cooperatively arranged. An annular bevel gear 14 is slidably sleeved on the rotating shaft 10 on the other side of the rotating shaft 10. An annular plate 15 is slidably sleeved outside the rotating shaft 10 on one side of the annular bevel gear 14. A moving mechanism is connected above the annular plate 15. Telescopic mechanisms 9 are connected to the circumferences of the annular plate 15 and the annular bevel gear 14. The moving mechanism can drive the annular plate 15 to move. When the annular plate 15 moves, it can drive the annular bevel gear 14 to slide outside the rotating shaft 10. When the annular bevel gear 14 meshes with the bevel gear 7, the bevel gear 7 can be locked.

[0021] Upper bearings are fixed on both side walls of the housing 1. An output shaft 3 is connected inside one of the upper bearings. One end of the output shaft 3 passes through the upper bearing and extends outward. A side gear 13 is fixed on the output shaft 3. A gear 12 is fixed on one side of the rotating shaft 10. The side gear 13 and the gear 12 are arranged in cooperation with each other. The diameter of the side gear 13 is larger than that of the gear 12. When the input shaft 2 rotates, it can drive the bevel gear 7 to rotate. When the bevel gear 7 rotates, it can drive the side bevel gear 11 to rotate. When the side bevel gear 11 rotates, it can drive the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, it can drive the gear 12 to rotate. When the gear 12 rotates, it can drive the side gear 13 to rotate. When the side gear 13 rotates, it can drive the output shaft 3 to rotate. Since the diameter of the side gear 13 is larger than that of the gear 12, a speed reduction effect can be achieved in this way.

[0022] Wherein, mounting plates 5 are fixed at the four corners of the bottom of the housing 1, and plate holes 6 are provided in the mounting plates 5. The housing 1 can be conveniently mounted through the mounting plates 5.

[0023] Wherein, mounting holes 4 are provided on one side of the input shaft 2 and the output shaft 3. The input shaft 2 and the output shaft 3 can be conveniently connected to the transmission shaft through the mounting holes 4.

The motor 19 is fixed on one side of the outer wall of the housing 1. The sliding plate 17 is fixed above the annular plate 15. The sliding plate 17 is slidably arranged in the groove plate 16. The two upper bearings 18 are respectively embedded in the side wall of the groove plate 16 and the side wall of the housing 1. A threaded rod 20 is connected inside one of the upper bearings 18. One end of the threaded rod 20 passes through the sliding plate 17 and the other upper bearing 18 and is connected to the motor 19. The threaded rod 20 is threadedly connected to the sliding plate 17. Starting the motor 19 can drive the threaded rod 20 to rotate. When the threaded rod 20 rotates, it can drive the sliding plate 17 to slide in the groove plate 16. When the sliding plate 17 moves, it can drive the annular bevel gear 14 to move on the rotating shaft 10.

[0025] Wherein, the telescopic mechanism 9 includes a side sliding hole 91 and a sliding rod 92. The side sliding hole 91 is provided around the annular plate 15. One end of the sliding rod 92 is fixed around the side wall of the annular bevel gear 14. The other end of the sliding rod 92 passes through the side sliding hole 91 and is fixed with a rod limiting plate 93. A spring 94 is sleeved on the sliding rod 92. One end of the spring 94 is fixed on the side wall of the annular bevel gear 14. The other end of the spring 94 is fixed on the side wall of the annular plate 15. Through the telescopic mechanism 9, the annular bevel gear 14 can be better meshed with the bevel gear 7.

[0026] Working principle and usage process of the present utility model: When it is necessary to lock the bevel gear 7, only need to start the motor 19. Starting the motor 19 can drive the threaded rod 20 to rotate, thereby driving the annular plate 15 to move. The movement of the annular plate 15 can drive the annular bevel gear 14 to slide outside the rotating shaft 10. When the annular bevel gear 14 meshes with the bevel gear 7, the bevel gear 7 can be locked, and thus the reducer can be stopped from working.
