Abstract

The invention discloses a combined-tooth reducer with adjustable clearance, which adopts a structure in which movable teeth and fixed teeth are combined with the same reduction ratio. The movable tooth transmission effectively improves the transmission accuracy and the bearing capacity of the reducer. Through the structure of combined teeth, the invention reduces the difficulty of processing and increases the scope of application; through the gap adjustment structure, the side gap of the fixed-tooth gear transmission is eliminated, the stepless preloading of the mechanism is realized, and the transmission mechanism is more suitable for The field of precision transmission; the invention has the advantages of adjusting the side clearance, high transmission precision, large bearing capacity, wide transmission ratio range, etc., and is suitable for wide application.

Description

technical field [0001] The invention relates to a movable tooth transmission device, in particular to a combined tooth reducer with adjustable clearance. Background technique [0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The movable tooth transmission can meet the requirements of compact structure, high transmission efficiency, wide transmission ratio range and large bearing capacity. The corresponding movable tooth transmission theory and technology are becoming more and more mature. [0003] Among them, the fixed-tooth transmission technology is the most mature and widely used, but the backlash problem of the fixed-tooth transmission cannot be effectively solved. The existence of backlash reduces the transmission accuracy of the fixed-tooth transmission. For this reason, it is necessary to develop a reducer that eliminates the backlash, so that it can be applied to the development ...
