Gear reduction unit

Abstract

The present invention relates to a gear reduction unit. The gear reduction unit comprises a rotating body not having an output rotating shaft, a gear input mechanism arranged at the eccentric position of the rotating body and used for obtaining the rotation kinetic energy at the eccentric position of the rotating body, and a gear output mechanism connected with the gear input mechanism and used for carrying out deceleration processing on the rotation kinetic energy obtained by the gear input mechanism and then outputting outwards. According to the present invention, the output rotating shaft on a motor rotor is canceled, so that the gear reduction unit of the present invention has the technical effects of compact structure and small occupied space.

Description

technical field [0001] The invention relates to a power source with a gear reduction device, in particular to a gear reduction device with a gear reduction device. Background technique [0002] The motor has many advantages such as high energy conversion efficiency, energy saving, and environmental protection, so it has been widely used in industrial production and life. In equipment such as electric vehicles, electric tricycles, electric vehicles, washing machines, etc., motors are indispensable. less equipment. Ordinary motors have a high speed. In order to obtain a suitable output speed, the motor needs to be decelerated in practical applications. At present, the commonly used method is to transmit the motor to the reducer and decelerate through the first-stage pulley, and set a first-stage pulley in the reducer. Or multi-stage gear reduction device to complete the deceleration of a certain speed ratio. This structure is not only complicated, but also takes up a lot of ...

Problems solved by technology

Although this structure further reduces the occupied space to a certain extent, because its principle is to use the inner circumferential space of the stator of the outer rotor motor to install the transmission device in the inner diameter space of the stator through the installation parts, it cannot be installed in the inner rotor without inner space. The application on the motor has certain limitations. At the same time, the motor body directly drives the shaft, and then decelerates the drive shaft through the transmission device installed in the inner diameter space of the motor, so it only reduces the occupied space to a certain extent, but the structure It is still not compact enough. Furthermore, when the volume of the transmission device needs to be increased in order to obtain a larger transmission ratio, the outer rotor motor must also increase the volume of the inner diameter to realize this invention. Obviously, this does not solve the substantive technical problem
