Description

Rolling worm gear power machine

Technical Field

The invention relates to the field of mechanical transmission, in particular to a device for transmitting rotary power sources such as a motor and an engine to pure electric drives such as a pure electric vehicle, a pure electric ship, a pure electric aircraft and a pure electric generator.

Background

In pure electric vehicles, pure electric ships, pure electric aircrafts, pure electric generators and other power equipment, the requirements for energy conservation and emission reduction of efficient power transmission exist, for example, pure electric vehicles, pure electric ships, pure electric aircrafts, pure electric generators and other pure electric equipment, the endurance mileage of one-time charging is very limited, and along with the increase of the use time of the pure electric vehicles, the pure electric ships, the pure electric aircrafts, the pure electric generators and other pure electric equipment, the increase of the charging times and the gradual decline of the endurance capacity, therefore, under the condition of equal power input, how to improve the performance of the pure electric equipment, the reduction of the energy consumption and the reduction of the pollution are problems to be solved urgently in the field.

According to the mechanical characteristics of the Archimedes screw, the cylindrical screw transmission can generate larger linear thrust by inputting smaller torque. The application of the screw to the transmission system will therefore have a positive effect on the power output.

Although the worm and worm wheel is widely applied to the field of mechanical transmission at present, the traditional worm and worm wheel transmission has certain defects, low transmission efficiency, easy abrasion and difficult high speed. The invention solves the defects of low transmission efficiency, easy abrasion and difficult high speed of the traditional worm and worm gear.
