Problems solved by technology

Others, such as the difference in the number of teeth between the stationary ring gear and the driving ringgear, and the optimal combination of the number of planetary gears are not clearly taught, and even the influence of the number of planetary gears on the reduction ratio is ignored. These need to be improved and clarified

Embodiment Construction

[0041] First, please refer to Figure 1 to Figure 6 , To disclose the configuration details of a preferred embodiment of the present invention, and explain the motor-combined deceleration device, or motor deceleration device, provided by the present invention. Its structure includes a housing 10, a support shaft 16, and a reducer 20. And a hollow motor 50.

[0042] by figure 1 and Figure 4 It can be seen that the casing 10 includes a first casing 11 and a second casing 12. A plurality of through holes 11a are formed on the peripheral edge of the first shell cover 11, and a corresponding number of screw holes 12a are formed on the peripheral edge of the second shell cover 12. The first shell cover 11 is connected to the first shell cover 11 with a corresponding number of screws 10b. The second shell cover 12 is assembled relative to the screw assembly to form a housing 10. Both ends of the casing 10 are formed with a closed end surface 15 and an open hole 14 respectively; wherei...

Abstract

The invention provides a speed reduction device combined with a motor. The speed reduction device comprises a machine shell with a center supporting shaft, and the machine shell is internally providedwith a speed reducer and a hollow motor. The hollow motor surrounds the periphery of a first-order planet gear train, and the speed reducer is composed of multiple orders of planet gear trains. Eachorder of planet gear train comprises a fixed inner gear ring, a movable inner gear ring, a planet gear set and a bearing base, the bearing bases and the movable inner gear rings between the adjacent orders of the planet gear trains have the character of integrated fixed connection and power transmission, then, the motor power is output to the outside of the machine shell in an extension manner, and the problems that a traditional motor speed reducer can only output the limited speed reduction ratio, and effective reduction of the integral arrangement space size is difficult are solved.

Description

Technical field [0001] The present invention relates to the combined technology of a motor and a gear reduction mechanism, and particularly relates to a motor reduction device in which a fixed support shaft is provided at a fixed end and is pivotally connected to a multi-stage planetary gear system without a sun gear. Background technique [0002] A motorized speed reducer, or geared motor, is an integrated power drive device that combines an electric motor and a gear reduction mechanism, or a non-gear reducer. Generally, under the same driving voltage, if the motor needs to have low speed and high torque output, the volume is usually relatively large, and the production cost is also high. If it is high speed and low torque output, the volume is usually relatively small, and the production cost is also high. The motor reducer allows the motor to generate high speed and low torque through the reducer to convert into low speed and high torque, providing a huge torque output in a re...
