Abstract

The invention discloses a small-tooth-difference planetary gear transfer transmission device, and relates to the field of mechanical transmission. The transmission device is single-input and double-output, the output is divided into two paths, three-stage speed reduction is realized by each path, two-stage speed reduction is realized by one small-tooth-difference gear transmission part, primary speed reduction is realized by a fixed-axis gear transmission part, the advantage of large transmission ratio of small-tooth-difference gear transmission are combined with the advantage that motion of fixed-axis gear transmission is stable, and compared with an existing transfer transmission device, the transmission device has the advantages that the structure is more compact and occupied space is smaller on the premise that the same transmission ratio is realized. According to the transfer transmission device, only two external gears are required for two-stage speed reduction through the small-tooth-difference gear transmission part of each path, three external gears are required for two-path transmission in total, and the three external gears are in dynamic balance arrangement, so that theoccupied space of the transmission device is further reduced; and the two ends of pins are connected with the two external gears through ball hinges, the installation is simple, and the stress performance is good.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a planetary gear transfer transmission device with small tooth difference. Background technique [0002] Most of the existing split transmissions adopt the form of fixed-axis gear transmission. However, the transmission ratio of the fixed-axis gear transmission is relatively small. In order to increase the transmission ratio, multi-stage gear transmission is required, resulting in a complex and large transmission device. Or the existing one-stage less-tooth-difference transmission needs two external gears with a phase shift of 180 degrees to be installed on the eccentric sleeve in order to meet the dynamic balance requirements. If the two-stage deceleration is realized, the output shaft of the first stage is the input shaft of the second stage. Four external gears are required, and the phases of two external gears in each stage are staggered by 180 degrees to achieve dynami...
