Abstract

The present invention provides a main decelerate device which includes a planet gear load-uniformed mechanism, a driver gear and a initiative bevel gear driven by the device, a driven bevel gear engaged with the initiative bevel gear and a speed differientiator connected to the driven bevel gear. It is characterized in that one of the sun gear in the planet gear load-uniformed mechanism is connected to the initiative bevel gear, another sun gear is connected to one of two engaged intermediate drive gears by an axle sleeve, another intermediate drive gear is connected to a secondary initiative bevel gear, the initiative bevel gear and the secondary initiative bevel gear are both connected to a driven bevel gear with double cog. The device divides the power into two parallel path powers with reverse rotate direction and equal torsion, and then combines the two powers into one power by making the main, secondary initiative bevel gears engage with the driven bevel gear with double cog, and passes the power to the speed differientiator by the driven bevel gear and output the power by an axle shaft gear, thereby complete the power output between interleaving shafts, conquers the axial direction offset of the driven bevel gear and increases the drive ability by times.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a main deceleration device, which belongs to the technical field of design and manufacture of mechanical transmission devices. Background technique [0002] The bevel gear single-stage reduction hypoid gear main reducer is an important part of the vehicle drive train. To ensure that the vehicle has sufficient ground clearance, the structure limits the diameter of the driven bevel gear of the reducer, so that the main reducer The service life and reliability of the transmission system become the most vulnerable link in the transmission system. The traditional solution is to increase the offset distance of the driving bevel gear. Although this method can increase the coincidence degree of the meshing teeth of the final reducer and improve the bending strength of the gear, but with the increase of the offset distance, the helical The angle is also increased accordingly, so that the equivale...
