Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment, as figure 1 As shown, the backlash-adjustable herringbone planetary transmission device is composed of a combined herringbone sun gear, planetary gear, inner ring gear, and planetary carrier. The whole device is input by the sun gear and output by the planetary carrier.

[0022] Such as figure 1 As shown, the combined inner ring gear is composed of a left-handed inner ring gear 1 and a right-handed inner ring gear 2, which are positioned by a conical pin and connected by a hexagon socket head screw 15.

[0023] Such as figure 2 As shown, the combined sun gear is composed of the main sun gear 12 with a shaft and the auxiliary sun gear 14 with a hole. It is positioned by a cylindrical pin B13. The shaft end of the main sun gear 12 is threaded and locked by a stopper nut B11. .

[0024] Such as image 3 As shown, the combined planetary wheel is compo...

Abstract

The invention belongs to the field of gear transmission and provides a combined type herringbone gear planet transmission device with adjustable backlashes. The device comprises an inner gear ring, sun gears, planet gears, planet carriers, planet gear bearings, a planet gear shaft and elastic pieces. According to the combined type herringbone gear planet transmission device with the adjustable backlashes, symmetrical bevel gears are combined to form a herringbone gear, machining with high difficulty of an integrated herringbone gear is brought down into machining with low difficulty of the common bevel gears, a new form of herringbone gear combined installation is provided, machining and assembling are simple, and manufacturing cost is reduced; the axial elastic pieces are installed between a main planet gear and an assistant planet gear, the main planet gear, the assistant planet gear and the elastic pieces are pre-tightened through nuts, meshing backlashes between the planet gears and the sun gears as well as between the planet gears and the inner gear ring are achieved, transmission errors caused by positive and negative rotation of the gears are eliminated, and transmission precision of the planet gears is improved.

Description

technical field [0001] The invention belongs to the field of gear transmission, and relates to a planetary gear device, in particular to a combined herringbone planetary gear device with adjustable backlash. Background technique [0002] Compared with ordinary gear transmission, the most notable feature of planetary gear transmission is that it can split power when transmitting power, so that it can be designed with small volume, small mass and compact structure. Therefore, it is mostly used in aero-engines, lifting equipment, wind power equipment, mining equipment etc. The gears of most planetary gear transmissions are spur gears or helical gears. Spur gear transmission has low coincidence and poor transmission stability, and the load capacity is often met by increasing the volume; helical gear transmission generates a large axial force, which requires high bearings, which weakens its load-bearing advantages; the use of integral herringbone gear ( Patent 201310649094.0, p...
