Abstract

The invention relates to a star-wheel speed reducer, which belongs to speed reducer technology field, comprising an input shaft, output shaft, gears, geared ring and a through cover, characterized in that the reducer casing is provided with the input shaft, output shaft, gears, geared ring. The input shaft is equipped with an eccentric sleeve, which is provided with double axial bearings, the eccentric sleeve is provided with two eccentric bearings equipped gears, the two gears are externally connected with tooth rings, the two gears are fixed on an even-carrying plate and the output shaft, the even-carrying plate is provided with a bearing, and a sealing ring is provided between the output shaft excircle and the through cover. The invention is provided with advantages of simple structure, smaller volume, high bearing capacity, low production cost, high transmission accuracy, convenient assemblage and combined application with other types of speed reducers, which can be widely used in speed reducer industry.

Description

technical field [0001] The invention belongs to the technical field of reducers, in particular to a coaxial output star gear reducer. Background technique [0002] At present, most of the products circulating in the reducer market are coaxial, such as cycloidal reducers; parallel shafts, such as ZY series hard tooth surface reducers; vertical shafts, such as worm gear reducers and other type of reducer. [0003] With the development of industrial technology, the mechanical structure design is becoming more and more compact, simple and practical, and the requirements for reducers are getting higher and higher, such as high torque, large transmission ratio and high transmission precision. At the same time, the smaller the volume, the better. [0004] ZY series hard tooth surface reducer meets the requirements of high torque, but its transmission ratio is up to 100, and it is a three-stage transmission. The volume is relatively large, and the input power requirement is large...
