The invention relates to the technical field of speed reducers, in particular to a two-speed reducer. When power is input through a high-speed motor, a high-speed brake releases braking, a low-speed motor is not started, a low-speed brake is in a braking state, and the external teeth of a differential planet gear reducer component with external teeth are braked; the power is sequentially transferred to a low-speed external gear reducer component through the differential planet gear reducer component with the external teeth and pinions and transferred to a low-speed output shaft, and thus the high speed is obtained. When the power is input through the low-speed motor, the low-speed brake releases braking, the high-speed motor is not started, and the high-speed brake is in the braking state; the power is transferred to the low-speed external gear reducer component through the differential planet gear reducer component with the external teeth and transferred to the low-speed output shaft, and thus the low speed is output. When the high-speed motor is not started, the high-speed brake releases braking, the high-speed motor is not started, the low-speed brake is in the braking state, the low-speed output shaft is in an unconstrained and non-braking state.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular to the structural composition of a two-speed reducer. Background technique [0002] The existing reducers are gear transmission reducers, planetary reducers, connecting rod reducers, three-ring reducers, etc. At present, these reducers can transmit torque and play the role of deceleration, but when the machine needs two speeds, the existing various types of reducers cannot meet the needs of modern technology. Contents of the invention [0003] The purpose of the present invention is to design and manufacture a speed reducer with two speeds and one neutral position, so as to make up for the deficiency of the existing reducer. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] On the box body 1, a differential planetary gear reducer with external teeth component 3 is installed, and the differential planetary gear reducer ...
