Description

M398728 December 10, 099, is a new type of description: [New technical field] [0001] This creation is about a reduction gear set wheel compared to a motor, especially a type that allows the inner rotor group to input the speed through the sun. The gear ratio of the gear, the planetary gear and the ring gear is gradually reduced, so that the wheel finally assembled with the carrier produces a low speed and high torque output. [Prior Art] According to the press, the motor is widely used as a main power source for various products, especially for devices with high speed or power demand. The principle of motor operation mainly uses electric energy to generate electromagnetic fields for the stator coated with coils. , and then push the rotor with magnetic rotation.:. For example, electric vehicles such as scooters are mainly used by elderly people and people with disabilities who are inconvenient for mobility. Therefore, in order to ride safely, it is not necessary to drive too fast, but to pass smoothly on the road. When the pit is uneven and does not overturn when climbing, it requires a higher torque. Therefore, the motor of the scooter is usually equipped with a speed reduction mechanism to achieve a low speed and high torque. Refer to the "Wheel Motor Structure with Reduction Gear Set" of the National Publication No. 126143, which is designed to fit the assembly of the speed reduction mechanism on the motor. It is mainly composed of a motor, a carrier and a reduction gear set; The stator is assembled with the motor casing, the rotor is fixed by the mandrel, and the first end of the mandrel is sleeved on the one end side of the motor casing, and the mandrel is disposed. The other end is passed through the middle bearing of the other side motor casing, and is fixed to the mandrel with an output gear, so that the motor can output the rotational force through the wheel-out gear. The frame number of the gear frame is Α0101. / Total 22 pages M3,98728 December 10, 099: The replacement page is set on the side of the motor casing, and the reduction gear set is set on the pivot of the carrier; the reduction gear set is at one end of the mandrel.
