An energy-saving and environment-friendly planetary wheel type two-stage electromagnetic transmission

Abstract

The invention discloses an energy-saving and environment-friendly planetary gear type two-stage electromagnetic transmission. The transmission comprises a transmission enclosure, an input main shaft, a clutch module, a brake module, a planetary gear system module and an output shaft, wherein the input main shaft, the clutch module, the brake module, the planetary gear system module and the output shaft are arranged in the transmission enclosure. The clutch module, the brake module and the planetary gear system module are sequentially connected in series through the input main shaft, and the output shaft is connected with the planetary gear system module. When the transmission is powered on, the clutch module works, the brake module is in a loosening state, and the input main shaft achieves constant speed output by driving the output shaft through the planetary gear system module. When the transmission is powered off, the clutch module does not work, a brake is in a braking state, and the input main shaft achieves variable speed output by driving the output shaft through the planetary gear system module. In the speed changing process of the transmission, the clutch module and the brake module do not need to be powered on, and therefore the clutch module and the brake module do not generate heat in the long-time working process, electric energy is not consumed, either, the environment-friendly and energy-saving requirements are met, and the transmission has the advantages of being safe and reliable in long-time use.

Description

technical field [0001] The invention relates to a planetary gear type two-stage electromagnetic transmission, specifically a transmission based on a planetary gear reducer, which realizes two-stage switching output through an electromagnetic and braking mechanism, and belongs to the field of electromechanical transmission devices. Background technique [0002] Among various mechanical devices, the speed output of the motor with reducer cannot meet the actual needs of the normal operation of the machine. The transmission is a commonly used mechanical device; If the sliding gear is used to achieve the purpose of speed change, the control is more complicated. In some small equipment, the mechanical weight will greatly increase the operating load of the machine. Such equipment has very strict control requirements for the size and weight of mechanical parts. The existing transmission can no longer meet these requirements. [0003] At present, in order to realize the demand for a...

Problems solved by technology

When the planetary two-stage electromagnetic transmission of this patent is working at a high speed output state, the electromagnetic coil is energized, that is, this type of electromagnetic transmission needs to be energized to achieve a long-term shifting working state, so the electromagnetic coil is easy to heat, so it needs to be installed on the shell of the electromagnetic transmission. Considering the heat dissipation structure design, resulting in high cost

Moreover, this type of electromagnetic transmission is not energy-efficient.
