Abstract

The invention discloses a gear backlash adjusting structure and an adjusting method thereof, and belongs to the technical field of gear backlash adjusting structures and adjusting methods thereof. Thetechnical problem to be solved is to provide the improvement of the gear backlash adjusting structure. According to the technical scheme adopted for solving the technical problem, the gear backlash adjusting structure comprises a platform, a slewing bearing mounting hole and an adjusting flange mounting hole are formed in the platform, a slewing bearing is fixedly connected to the slewing bearingmounting hole, an adjusting flange is fixedly connected to the adjusting flange mounting hole, a transition flange is arranged between the slewing bearing and the platform, a motor and a speed reducer are fixedly connected to the lower portion of the adjusting flange, a pinion is arranged on the adjusting flange, the center of the pinion does not coincide with the center of the adjusting flange,the pinion is engaged with the slewing bearing, a spline of the pinion is fixed to the shaft end of the speed reducer, and a notch is formed in the adjusting flange. The gear backlash adjusting structure and the adjusting method thereof are applied to gear backlash adjustment of engineering vehicles.

Description

technical field [0001] The invention discloses a gear backlash quick adjustment structure and its adjustment method, and belongs to the technical field of gear backlash quick adjustment structure and its adjustment method. Background technique [0002] At present, the hydraulic motor pinion meshes with the slewing bearing to drive its rotation, which is a common structural form of many special devices for engineering vehicles. Too large or too small gear backlash will have disadvantages for use: too much backlash will cause backstroke error, impact, and large noise, while too small backlash will cause no oil storage space, poor lubrication, and gear seizure. [0003] The reasons why the gear backlash cannot meet the requirements are as follows: 1) gear machining error; 2) platform center hole distance machining error; 3) installation and coordination error of each component. [0004] Theoretically, there are two main methods for gear backlash adjustment: 1) base tooth thick...
