Abstract

The invention relates to a split-type herringbone gear and a planetary transmission device thereof, which belong to the technical field of mechanical transmission; it includes a radially segmented and assembled herringbone internal gear, an axially separated herringbone external gear, and a gear with a load equalizing effect. Herringbone planetary gear and planet carrier; herringbone planetary gears are arranged on the radially segmented herringbone inner gear, and different herringbone planetary gears are connected through a planet carrier; axially separated herringbone outer gear Mesh connection with herringbone planetary gear. The present invention realizes a herringbone planetary transmission device with controllable stiffness fluctuation and good planetary gear load balance through the mutual cooperation between the phase-adjustable herringbone external gear, the herringbone internal gear and the herringbone planetary gear , which solves the problems of difficult machining, difficult installation and large fluctuations in stiffness of herringbone gears, and provides an effective transmission structure for mining, marine and aviation high-power applications.

Description

technical field [0001] The invention relates to a split type herringbone gear and a planetary transmission device thereof, belonging to the technical field of mechanical transmission. Background technique [0002] Herringbone gear transmission is widely used in the transmission system of heavy machinery because it can work under large load capacity without axial thrust, especially in high-power reducers for mining, marine and aviation. The current herringbone gear is generally of integral structure, and its 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 current main problems of this symmetrical structure of gear teeth are: 1. It is particularly difficult to process, especially the large herringbone internal gear; 2. It is difficult to install, especially in the herringbone planetary gear train. It is difficult or even impossible to install the sun...
