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

[0033] First, please incorporate the Figure 1 to Figure 6 , discloses the configuration details of a preferred embodiment of the present invention, and illustrates that the reduction gear combined with the motor provided by the present invention, or called the motor reduction gear, its structural composition includes a casing 10, a support shaft 16, and a speed reducer 20 And a hollow motor 50.

[0034] Depend on figure 1 and Figure 4 It can be seen that the casing 10 includes a first shell 11 and a second shell 12 . A plurality of through holes 11a are formed on the peripheral edge of the first shell 11, and a corresponding number of screw holes 12a are formed on the peripheral edge of the second shell 12, and the first shell 11 is connected with the corresponding number of screws 10b. The second casing 12 is combined with the screws to form a casing 10 . The two ends of the casing 10 are respectively formed with a closed end face 15 and an open hole 14; wherein, the cl...

Abstract

The invention provides a deceleration device combining with a motor, and the device comprises a speed reducer and a hollow motor which are configured in a motor case with a central supporting shaft. The hollow motor is arranged around the periphery of a first-order planetary gear system, and the speed reducer comprises a multi-order planetary gear system. The planetary gear system at each order comprises one fixed inner gear ring, one movable inner gear ring, one planetary gear group and one bearing seat. The bearing seats and the movable inner gear rings of the planetary gear system at the adjacent orders are enabled to have the characteristic of integrated fixed connection for power transmission, thereby achieving the extended outputting of motor power to the outside of the motor case soas to solves a problem that a conventional motor speed reducer just can output a limited speed reduction ratio and a problem that the overall configuration space (volume) is difficult to reduce.

Description

technical field [0001] The invention relates to the combination technology of a motor and a gear reduction mechanism, in particular to a motor reduction device with a multi-stage sun gearless planetary gear train pivoted to a fixed support shaft provided by a fixed end. 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 a motor has 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. Low, while the motor reducer allows the motor to generate high speed and low torque through the reducer to convert it into low speed and high torque through the reducer, providing huge torque output in a relatively small volume, s...
