Embodiment 1

[0022] The present invention provides a gear meshing gap adjustment mechanism, which is used to adjust the meshing gap between the large gear 1 and the pinion 2 of the mutual meshing transmission, and its structure is as follows figure 1 and figure 2 shown. The gear meshing gap adjustment mechanism includes a column 3 and a motor 4, an eccentric disc 5 is rotatably mounted on the column 3, the motor 4 is eccentrically arranged on the eccentric disc 5, and is fixedly installed on the eccentric disc 5 On one side, the output shaft of the motor 4 passes through the eccentric disc 5 and is coaxially fixedly connected with the pinion 2; the gear mesh adjustment mechanism also includes an eccentric adjustment mechanism for adjusting the Eccentricity.

[0023] Specifically, please refer to figure 2 , the eccentric adjustment mechanism includes several arc-shaped slots 50 and several positioning bolts 51, and several arc-shaped slots 50 are opened on the eccentric disk 5 along th...

Abstract

The invention discloses a gear engagement clearance adjusting mechanism, and belongs to the technical field of gear transmission. The gear engagement clearance adjusting mechanism comprises a stand column and a motor, wherein an eccentric disc is rotationally installed on the stand column, the motor is eccentrically arranged on the eccentric disc and fixedly installed on one side of the eccentricdisc, an output shaft of the motor penetrates through the eccentric disc and is coaxially and fixedly connected with a small gear, and the gear engagement clearance adjusting mechanism further comprises an eccentric adjusting mechanism used for adjusting the eccentricity of the eccentric disc. According to the gear engagement clearance adjusting mechanism, eccentric adjustment is adopted, a traditional bolt direct-ejection adjusting mode is replaced, quantitative adjustment of the gear engagement clearance is changed into progressive adjustment, and adjustment of the clearance amount can be accurately controlled; and meanwhile, the eccentric disc can be positioned through positioning bolts and adjusting bolts, it can be avoided that when the positioning bolts or the adjusting bolts are loosened, the gear engagement clearance loses precision greatly, and the double-insurance function is achieved.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a gear meshing gap adjustment mechanism. Background technique [0002] At present, the adjustment of the gear meshing gap used in the equipment on the market mainly adopts the bolt straightening adjustment method, and the gap adjustment and locking are realized by the nut locking after the bolt is straightened. However, it is difficult to control the adjustment amount of the bolt straight top clearance, which leads to a sharp drop in gear transmission accuracy, transmission efficiency and transmission torque. Contents of the invention [0003] The purpose of the present invention is to provide a gear meshing gap adjustment mechanism to solve the problem that the gear meshing adjustment used in the current market equipment mainly adopts the bolt straight top adjustment method, and the gap adjustment is difficult to control, resulting in gear transmission accuracy, tran...
