Problems solved by technology

[0007] The above two methods have their own characteristics, but there are also obvious shortcomings.
The disadvantage of method 1 is that the tooth backlash cannot be automatically compensated after the gear is worn out, and the gear tooth thickness and pitch tolerance are strictly required during processing, which will affect the flexibility of the transmission
The disadvantage of method 2 is that the adjustment and assembly process is more complicated, the transmission stiffness is low, and it is not suitable for transmission of large torque

Abstract

The invention proposes a device and a method for eliminating a gear side gap, a control system and a control method. The device for eliminating the gear side gap comprises a first motor shaft, a second motor shaft and an output shaft arranged in parallel, a first small gear fixedly connected to the first motor shaft, a second small gear fixedly connected to the second motor shaft, and a large gear fixedly connected to the output shaft; the first small gear and the second small gear are respectively engaged with the large gear; and in the gear rotating process, the first small gear is always engaged with one side gear surface of the large gear, and the second small gear is always engaged with other side gear surface of the large gear. The device and the method for eliminating the gear side gap, the control system and the control method can effectively eliminate the side gap in a gear transmission pair to improve the gear transmission precision and the equipment positioning precision.

Description

technical field [0001] The invention belongs to the technical field of backlash-free gear transmission, and in particular relates to a device, method, control system and control method for eliminating backlash of gears. Background technique [0002] Mechatronic equipment, such as servo turntables, often use gear pair transmission. And above-mentioned equipment is owing to often being in reversing rotation state in the course of work, if there is backlash in gear transmission pair in transmission chain, will make gear motion lag behind command system when reverse rotation. It affects the system accuracy of the transmission chain, thus greatly affecting the positioning accuracy and stability of the equipment. Therefore, necessary measures must be taken to eliminate the backlash in the gear transmission pair to improve the accuracy of gear transmission and the positioning accuracy of the equipment. The commonly used methods to eliminate the backlash of spur gears are as follo...
