Abstract

The invention discloses an adjustable precise planetary gear deceleration machine. A planetary gear group is mounted in a deceleration machine; a second bearing and a first bearing are correspondinglyarranged at the left and right ends of a planetary bracket of the planetary gear group in a sleeving mode; a limiting ring at the left end of the planetary bracket is attached to the left end face ofthe second bearing; adjusting nuts are in thread connection with an output shaft of the planetary bracket, and are attached to the right end face of the first bearing. When extrusion force to the first bearing by the adjusting nus is adjusted, inner rings of the first and second bearings are subjected to relative small displacement, so that output shaft axial movement caused by axial backlash ofthe first and second bearings can be reduced, the aims of improving transmission accuracy and meeting application requirements are achieved, and great consumption of manpower and material resources caused by improving production and machining accuracy is avoided.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an adjustable planetary gear reducer. Background technique [0002] Planetary gear reducers are generally used in conjunction with servo motors. A certain power private server motor is equipped with planetary gear reducers with different reduction ratios to reduce the speed of the motor and increase the torque to meet various needs. In recent years, especially because of the advantages of compact structure, small size, large carrying capacity, high efficiency, and high transmission precision, precision planetary gear reducers have been widely used in machine tools, packaging, printing machinery and robotics industries. In particular, the precision planetary gear reducer is required to have high transmission accuracy, that is, the backlash is required to be small, and generally the backlash is required to be less than 5 arc minutes, or even 3 arc minutes. The backlash is also ca...
