Abstract

The invention discloses a single-eccentric short transmission chain speed reducer. The single-eccentric short transmission chain speed reducer comprises a fixed main body, a bearing sleeve, a power input shaft, a power output shaft and a duplicate gear; the power input shaft comprises positive axis parts at the two ends and an off-axis part in the middle, the axes of the positive axis parts and the off-axis part do not coincide, the duplicate gear is arranged on the off-axis part of the power input shaft in a sleeving mode through a third bearing, and the duplicate gear comprises a first external gear and a second external gear; a first inner gear ring is arranged on the portion, corresponding to the first external gear, of the fixed main body, a second inner gear ring is arranged on the portion, corresponding to the second external gear, of the power output shaft, the first external gear and the first inner gear ring are in internal meshed transmission, and the second external gear and the second inner gear ring are in internal meshed transmission. The single-eccentric short transmission chain speed reducer has the advantages of being simple in structure, short in transmission chain, high in transmission efficiency, stable in transmission, large in transmission moment, wide in speed reducing ratio range and the like.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery and relates to a speed reducer, in particular to a single eccentric short transmission chain speed reducer. Background technique [0002] The reducer is a relatively precise machine, the purpose of using it is to reduce the speed and increase the torque. It has a wide variety, different models, and different types have different uses. According to the transmission type, it can be divided into gear reducer, worm reducer and planetary gear reducer; according to the number of transmission stages, it can be divided into single-stage and multi-stage reducer; according to the gear shape, it can be divided into cylindrical gear reducer and bevel gear reducer And conical-cylindrical gear reducer; according to the layout of the transmission, it can be divided into expansion type, shunt type and coaxial type reducer. [0003] As an important part of mechanical transmission, the reducer is wi...
