Abstract

The invention is a variable-tooth thickness involute planetary reducer, comprising input eccentric shaft, left end cover, right end cover and output shaft, where the left and right end covers are fixed with each other to form a working cavity, in which a reducing mechanism is arranged; and it is characterized in that: the reducing mechanism comprises variable tooth thickness involute planetary gear, and variable tooth thickness involute inner gear, where the variable tooth thickness involute planetary gear is installed by bearing on the eccentric section of the input eccentric shaft and forms power connection with the output shaft, and the variable tooth thickness involute inner gear is fixed on the inner wall of the left end cover to form small tooth difference planetary engaging auxiliary, and the input eccentric shaft is equipped with compensating mechanism and spring adjusting mechanism. And it has advantages of precision transmission and simple mechaning, able to eliminate the gap and automatically keep no-side gap engaging with the variable tooth thickness involute inner gear and automatically compensate after abrasion.

Description

technical field [0001] The invention belongs to an involute planetary reducer with few tooth differences in the field of mechanical engineering. Background technique [0002] Planetary transmission with small tooth difference is a widely used transmission mode. With the development of precision transmission, new requirements are put forward for transmission accuracy and backlash. A kind of invention patent disclosed in Chinese patent CN1482380A is called "conical cycloidal planetary transmission device", which proposes to use a conical cycloidal planetary transmission with variable tooth thickness to reduce and control backlash. The US patent ADJUSTABLE CYCLOIDAL SPEED REDUCER (Patent No. 5,145,468) also proposes a conical cycloid planetary gear reducer. However, since the above-mentioned patents use cycloidal pinwheel transmission, and the processing of cycloidal pinwheels requires advanced special equipment, the process system is complicated, and the cycloidal pinwheels a...
