Abstract

The invention discloses a double-arc gapped meshing few tooth difference planet transmission device. A box and an eccentric shaft arranged in the box are included. A first eccentric part and a secondeccentric part of the eccentric shaft are provided with two outer gears correspondingly. The box inner walls corresponding to the outer gears are provided with inner gears, and the inner gears and theouter gears are matched for meshing. A plurality of drive pins are further arranged between the two outer gears. The two ends of the multiple drive pins are connected and matched with two end discs,a planet carrier structure is formed, and power is output. Tooth profiles of the inner gears and tooth profiles of the outer gears are arcs. Initial meshing gaps exist in the inner gears and the outergears. The double-arc gapped meshing few tooth difference planet transmission device solves the problems about complex curve high-precision machining and tooth profile shape correcting, and a good precision running effect is kept.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a planetary transmission device with double circular arc gap meshing and less tooth difference Background technique [0002] Due to the advantages of large transmission ratio, compact structure, large load capacity and high transmission efficiency, planetary transmission with small tooth difference has been widely used in power transmission fields such as metallurgy, mining and chemical industry. Due to the large number of meshing teeth and the obvious error averaging effect, this transmission has attracted more and more attention in the fields of precision transmission such as robotics, aerospace and CNC machine tools in recent years. [0003] The existing implementation schemes include cycloid planetary transmission with small tooth difference, involute planetary transmission with small tooth difference, etc. [0004] The tooth profiles of the conjugate gears of the ...
