Abstract

The invention relates to a differential planet gear, in particular to a dual-input micro integrated differential planet gear. In order to solve the problems that planet gears in the prior art are limited by the gear number and the modulus, most planet gears are large in size and of a scattered structure, and the plant gears in the prior art cannot be directly used for differential transmission easily, the micro integrated differential planet gear comprises an input shaft end bearing, an input shaft sleeve, an input shaft gear, an input shaft, a planet gear assembly, an output shaft connection rod, an output shaft end sliding bearing, a gear frame gear, an output shaft, an input shaft middle bearing and an output shaft middle bearing; the input shaft end bearing, the input shaft sleeve and the input shaft gear are sequentially arranged on the input shaft in a sleeving manner from the input end of the input shaft to the output end of the input shaft; the output end of the input shaft penetrates the input shaft middle bearing to be inserted in the planet gear assembly; the output shaft end sliding bearing and the output shaft connection rod are arranged on the output shaft in a sleeving manner; the input end of the output shaft penetrates the output shaft middle bearing to be fixedly inserted in the planet gear assembly; and a gear rack gear is fixedly installed on the planet gear assembly. The invention belongs to the field of machines.

Description

technical field [0001] The invention relates to a differential planetary gear, in particular to a double-input miniature integrated differential planetary gear. Background technique [0002] In many mechanical fields, especially underactuated prosthetic hands, differential mechanisms are often used. The differential mechanism is divided into single-input multiple-output differential and multiple-input single-output differential. Specific to the mechanical structure, including differential pulley, differential screw connecting rod, differential planetary gear, differential rack and pinion, etc. The principle of the pulley system is simple but the structure is complex. When it is reversed, it needs to be recovered by elastic elements, and the problem of preload will bring great troubles in practical applications. The structure of the differential screw link is simple, but it is difficult to achieve a specific transmission ratio. The ratio of the differential gear and rack i...
