Abstract

The invention relates to an eccentric planet axis mechanism with tunable centre-to-centre distance and its regulation means. The eccentric planet axis mechanism includes a planet frame, an eccentric planet axis, a bearing, a planet wheel and pins. Concentric axis are provided at both dies of the eccentric planet axis, and an eccentric spindle is provided in center; a pair of semi-circle pin holes are provided at the peak and lowest point of inner ring at any one end of the planet frame; at least a pair of symmetrical semi-circle pin holes are provided at the outer ring of the planet axis; the two semi-circle pin holes align the rear formed pin holes; the pins are mounted in the pin holes, and the planet frame is in positioning fixation with the eccentric planet axis. The invention is beneficial for generalization, large-scale and standardization of the production of the eccentric planet axis mechanism.

Description

technical field [0001] The invention relates to a deceleration technology of mechanical transmission, in particular to an eccentric planetary shaft mechanism with adjustable center distance and an adjustment method thereof. Background technique [0002] As we all know, planetary gear transmission has many unique advantages compared with ordinary gear transmission. Its most notable feature is that it can perform power splitting when transmitting power; at the same time, its input shaft and output shaft are coaxial, that is, the output shaft and input shaft can be set on the same main axis. Therefore, planetary gear transmission has been used to replace ordinary gear transmission, and as a reducer, speed increaser and speed change mechanism in various mechanical transmission systems. Especially for the gear transmission mechanisms of aero-engines, lifting transportation, petrochemical and weapons that require small size, small mass, compact structure and high transmission eff...
