Description

Technical Field

[0001] This utility model belongs to the field of gearbox technology, specifically relating to a gearbox eccentric adjustment clearance reduction transmission mechanism. Background Technology

[0002] In machining processes, rotary tables are used. A drive motor, in conjunction with a speed reducer, rotates the rotary table. The speed reducer's transmission structure, such as gears or worm gears, slows down the input shaft's speed, thus lowering the output shaft's speed. By reducing the speed, the speed reducer increases the output torque. This is crucial for equipment requiring high torque. By adjusting the balance between speed and torque, the speed reducer can optimize the drive system's efficiency and reduce energy loss.

[0003] However, in actual use, the gear clearance in the gearbox cannot be adjusted, which leads to low machining accuracy. Therefore, we propose an eccentric gearbox clearance adjustment reduction transmission mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a gearbox eccentric clearance adjustment reduction transmission mechanism to solve the problem mentioned in the background art that the clearance of the gears in the gearbox cannot be adjusted during actual use, and the inability to adjust the clearance leads to low machining accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gearbox eccentric adjustment clearance reduction transmission mechanism, including a turntable base, a gearbox fixedly mounted on the side of the turntable base, a drive motor and a reducer fixedly mounted on the surface of the gearbox, the output shaft of the drive motor being fixedly connected to the input shaft of the reducer, a turntable plate rotatably mounted on the turntable base, a transmission component one and a transmission component two being provided on the gearbox, the output shaft of the reducer driving the turntable plate to rotate through the transmission component one and the transmission component two, and an eccentric sleeve and an eccentric shaft cooperating with the transmission component one being provided inside the gearbox.

[0006] By adopting the above scheme, through the use of transmission component one and transmission component two, and the use of eccentric shaft and eccentric sleeve, it is possible to achieve simple and efficient adjustment of the backlash, thereby achieving higher mechanical precision. The overall structure is simple and easy to operate. The gap between transmission gear three and transmission gear four is achieved by adjusting the eccentric shaft.

[0007] In a preferred embodiment, the transmission assembly includes a first transmission gear, a second transmission gear, a third transmission gear, and a fourth transmission gear. The eccentric sleeve is used in conjunction with the second transmission gear, and the eccentric shaft is used in conjunction with the third transmission gear. The first transmission gear is fixedly mounted on the outer surface of the output shaft of the reducer. The second and third transmission gears are rotatably mounted on the inner wall of the gearbox. The first and second transmission gears, the second and third transmission gears, and the third and fourth transmission gears mesh with each other.

[0008] By using the above scheme, the transmission gear 1, transmission gear 2, transmission gear 3 and transmission gear 4 are used in combination, so that when the drive motor starts and drives the reducer to work, it will drive the transmission component 2 to move through the transmission component 1, and the eccentric clearance can be adjusted by cooperating with the eccentric sleeve and eccentric shaft.

[0009] In a preferred embodiment, the transmission assembly two includes a worm gear fixedly mounted on the surface of the turntable plate and a worm rotatably mounted on the surface of the turntable base. The worm and the worm gear mesh with each other, and the transmission gear four is fixedly mounted on the outer surface of the worm.

[0010] The above scheme utilizes the meshing transmission of a worm gear and a worm, so that the rotation of the worm drives the worm wheel to rotate, which in turn drives the rotary table to rotate, thereby achieving rotary machining.

[0011] In a preferred embodiment, the gearbox has openings on both its left and right opposite sides.

[0012] Using the above method, the opening allows for the inspection and maintenance of the gearbox's interior.

[0013] In a preferred embodiment, the drive motor is specifically a servo motor.

[0014] Using the above method, precise angle control can be achieved.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This gearbox eccentric clearance adjustment reduction transmission mechanism uses transmission component one and transmission component two in cooperation, and eccentric shaft and eccentric sleeve in cooperation. By adjusting the eccentric shaft, the clearance between transmission gear three and transmission gear four can be adjusted, which can achieve simple and efficient adjustment of the reverse clearance, thereby achieving higher mechanical precision. The overall structure is simple and easy to operate. Attached Figure Description

The overall structure is simple and easy to operate.

[0022] Transmission assembly one includes transmission gear one 7, transmission gear two 8, transmission gear three 9, and transmission gear four 10. Eccentric sleeve 11 is used in conjunction with transmission gear two 8, and eccentric shaft 12 is used in conjunction with transmission gear three 9. Transmission gear one 7 is fixedly installed on the outer surface of the output shaft of reducer 6. Transmission gear two 8 and transmission gear three 9 are rotatably installed on the inner wall of gearbox 4. Transmission gear one 7 and transmission gear two 8, transmission gear two 8 and transmission gear three 9, and transmission gear three 9 and transmission gear four 10 mesh with each other. Transmission gear two 8 and transmission gear three 9 pass through the openings on the left and right sides of gearbox 4, respectively. By using transmission gear one 7, transmission gear two 8, transmission gear three 9, and transmission gear four 10 in conjunction, when drive motor 3 starts and drives reducer 6 to work, it will drive transmission assembly two to move through transmission assembly one, and achieve eccentric adjustment clearance in conjunction with eccentric sleeve 11 and eccentric shaft 12.

[0024] The gearbox 4 has openings on its left and right opposite sides and surface, which allow for inspection of the inside of the turntable plate 5.

[0025] The drive motor 3 is specifically a servo motor, which can achieve precise angle control.

[0026] In use, the CNC system issues commands to control the drive motor 3 to drive the reducer 6, which in turn drives the transmission gear 7 to rotate. The meshing action of the transmission gears 7, 8, and 9 drives the worm gear 13 to rotate. The meshing action of the worm gear 13 and the worm wheel 2 drives the worm wheel 2 to drive the turntable plate 5 to rotate, thus realizing rotary machining. The eccentric shaft 12 and the eccentric sleeve 11 can be used together to achieve simple and efficient adjustment of the backlash, thereby achieving higher mechanical precision. The overall structure is simple and easy to operate.
