A combined electromagnetic coupling type deceleration device

Abstract

The invention relates to a combined electromagnetic coupling type reduction gear, which comprises an output shaft, a plurality of driving components and a controller. A driven electromagnetic wheel is sleeved on the output shaft, and the driving component includes a driving motor and a driving electromagnetic wheel. The rotating magnetic field of the concave permanent magnet generates electromagnetic torque on the electromagnetic coupling of the driven electromagnetic wheel to realize energy transfer. There is no mechanical contact, no wear, and no mechanical noise during operation, and there is no need for oil lubrication between the driving electromagnetic wheel and the driven electromagnetic wheel. , the flexible transfer of energy between the two is beneficial to the flexible distribution of the power of each drive motor. The rotating concave permanent magnet drives a strong magnetoresistance effect on the driven electromagnetic wheel of the salient pole structure, forming an electromagnetic torque, which is beneficial to improve the system efficiency. Multiple drive components run in parallel, and multiple drive electromagnetic wheels with concave permanent magnets generate synthetic drag torque for the same driven electromagnetic wheel at multiple points. The system has high efficiency, good fault tolerance and tolerance, high assembly integration, and volume. Small, easy to install and maintain.

Description

technical field [0001] The invention relates to the technical field of electromagnetic coupling, in particular to a combined electromagnetic coupling type deceleration device. Background technique [0002] Generally speaking, the traditional mechanical reducer is manufactured based on the principle that the gear coupling of the main and driven wheels transmits energy, and the ratio of the number of teeth of the driving gear to the number of teeth of the driven gear is less than 1. The master and slave gears transmit energy in direct contact, and noise is generated during the working process. There is tooth wear, energy consumption of the teeth, and the master and slave gears heat up. Oil lubrication is required to reduce wear and energy consumption and reduce the temperature of the master and slave gears. Mechanical reduction device system Usually, a motor that can match the load power is used to drive the reducer through the shaft connector. The mechanical reduction device ...
