Abstract

The invention relates to a split herringbone gear and a planetary transmission device thereof and belongs to the technical field of mechanical transmission. The split herringbone gear comprises a radial segmented split-mounting herringbone-tooth internal gear, an axial separate herringbone-tooth external gear, herringbone-tooth planetary gears with a uniform loading effect and a planetary carrier,wherein the herringbone-tooth planetary gears are arranged on the radial segmented split-mounting herringbone-tooth internal gear, the different herringbone-tooth planetary gears are connected through the same planetary carrier, and the axial separate herringbone-tooth external gear is connected with the herringbone-tooth planetary gears in a meshing mode. Through mutual cooperation of the phase-adjustable herringbone-tooth external gear, herringbone-tooth internal gear and herringbone-tooth planetary gears, the herringbone gear planetary transmission device with controllable rigidity fluctuation and a good uniform loading condition of the planetary gears is obtained, the problems of high machining difficulty, difficult mounting and large rigidity fluctuation of an existing herringbone-tooth gear are solved, and an effective transmission structural form is provided for high-power application occasions of mines, ships and aviation.

Description

Technical field [0001] The invention relates to a split herringbone gear and a planetary transmission device thereof, belonging to the technical field of mechanical transmission. Background technique [0002] Since the herringbone gear transmission can work under a large load capacity without axial thrust, it is widely used in the transmission system of heavy machinery, especially in the application of high-power reducers for mining, ships and aviation. The current herringbone gears generally have an integral structure, and their structural feature is that half of the tooth width of the cylindrical gear is set as right-handed teeth and the other half of the tooth width is set as left-handed teeth. The main problems with this symmetrical structure of the gear teeth are: 1. It is particularly difficult to process, especially the herringbone internal gear with a larger size; 2. It is difficult to install, especially in the herringbone planetary gear train, There are difficulties in...
