Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 As shown, a radially balanced reducer with less tooth difference for the driving wheel of a truck includes a housing 1, an input shaft 11, an output shaft 3, and a gear assembly that drives and connects the two shafts. The input shaft 11 and the output shaft 3 rotate It is connected to the housing 1 and the axes of the two coincide. The gear assembly is arranged in the housing 1. The gear set includes a transmission gear 301, a double gear 2 and a ring gear 107. The transmission gear 301, the double gear 2 It is nested in the same radial plane as the ring gear 107 from inside to outside. The double gear 2 is eccentrically mounted on the input shaft 11 and the two are connected in rotation. The matching eccentric shaft section 1101, the double gear 2 is provided with the outer ring gear 201 meshing with the ring gear 107 an...

Abstract

The invention relates to the field of speed reducers, in particular to a radial equilibrium small-tooth-difference speed reducer for a carrier driving wheel. In order to overcome the defects of complex structure, large axial length, high gear load intensity, short service life and the like of an existing driving wheel speed reducer, the radial equilibrium small-tooth-difference speed reducer for the carrier driving wheel is provided; an input shaft is provided with an eccentric shaft segment and rotatably connected with a dual gear, the dual gear is meshed with a fixed gear ring and a transmission gear fixedly connected with an output shaft at the same time, radial transmission is performed on a working plane, the eccentric shaft segment and a corresponding rotating connection portion areequally stressed, radial equilibrium is achieved without additional equilibrium weights, bending or failure fracture of the eccentric shaft segment will not occur, the axial length of the whole speedreducer is reduced, the structure of the speed reducer is more compact, the power output structure is simple, the gear load intensity is low, and the service life is long.

Description

technical field [0001] The invention relates to the field of speed reducers, in particular to a radially balanced speed reducer with less tooth difference for driving wheels of a transport vehicle. Background technique [0002] The reducer is an important transmission device on the driving wheel of the truck, which is used to connect the driving motor and the wheel. The input and output of the reducer used for the driving wheel of the existing truck are set coaxially, and the multiple transmission gears inside the reducer are driven along the axial direction. The reducer adopts a low power density design, with complex structure, large axial length, and high gear load strength , short life; further, it is inconvenient to disassemble and maintain the reducer. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to solve the defects of existing drive wheel reducers such as complex structure, large ...
