An eight-cone gear less tooth difference reducer

Abstract

The invention discloses an eight-bevel gear few tooth difference speed reducer. A bevel gear set is arranged on an input shaft; bevel gears Z1, Z2, Z3 and Z4 surround a rectangle to form a first-grade differential, and bevel gears Z5, Z6, Z7 and Z8 surround a rectangle to form a second-grade differential, wherein the bevel gears Z1 and Z7 are connected with the input shaft through flat keys; the bevel gears Z3 and Z5 are connected to fix the two grades of differentials without contacting with the input shaft; the whole bevel gear set is respectively connected with a base through bearings B1, B2, B4 and B6; the bevel gears Z6 and Z8 are connected with a rotor through bearings B3 and B5; the outer cylindrical surface of the rotor, the base and an upper cover form a slide pair; the torque on the bevel gear set is firstly transferred to the rotor, so that the rotor rotates; and one end of the rotor is connected with an output shaft, so that the torque on the rotor can be transferred to the output shaft. Compared with a traditional speed reducer, the eight-bevel gear few tooth difference speed reducer has no eccentric mechanism on a high-speed shaft and no flexible wheel mechanism, has the characteristics of simple structure, small size, light mass and high output torque, and can obtain higher transmission ratio.

Description

technical field [0001] The invention relates to a reducer with a large transmission ratio, in particular to a reducer with eight bevel gears and few teeth differences. Background technique [0002] At present, the general-purpose reducers include traditional reducers such as bevel gear reducers and worm gear reducers. Among them, the bevel gear reducer mainly refers to the bevel gearbox reducer. Its transmission efficiency can generally reach more than 90%, long service life and stable performance. It is the most widely used reducer in engineering, but the bevel gearbox reducer The transmission ratio of the device is small, the transmission efficiency is low during multi-stage deceleration, and the size of the whole machine is large. The single-stage worm gear reducer can obtain a large reduction ratio and has the ability of reverse self-locking, but the wear between the teeth is severe, the heat is large, and the transmission efficiency usually does not exceed 50%. When th...

Problems solved by technology

Because the harmonic reducer contains flexible splines, its starting torque is large, its heat dissipation is poor, and its service life is short
