Problems solved by technology

[0002] The existing known planetary gears are usually composed of several planetary gear sets in series. When the number of series is more, the difficulty of assembly will also increase, and the concentricity of each planetary gear set cannot be guaranteed, which may easily cause unsmooth operation. As a result, a large noise is generated, and in serious cases, it cannot even be started. In addition, the existing power device must connect the planetary gear and the output shaft of the motor concentrically. Therefore, in applications with limited length, the overall power transmission device must be used as a The correction of length and reduction ratio will cause difficulties in design and manufacture, and on the other hand, it will not have the effect of shock absorption and noise reduction

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment

[0019] The present invention is described further:

[0020] like figure 1 As shown, a gear power transmission device includes a housing 60 on which several heat dissipation ports are opened; a soundproof room, a motor 30, a gear set 40 and a planetary gear set assembly 50A are arranged in the housing 60;

[0021] Motor 30 is arranged in soundproof chamber, and motor 30 is provided with motor output shaft 31, and motor output shaft 31 extends out of soundproof chamber (not shown in the figure); In order to improve soundproof effect, soundproof chamber is made up of six asbestos soundproof boards. A first gear 41 is sleeved on the motor output shaft 31 .

[0022] The gear set 40 includes a second gear 43, a transmission shaft 61, a third gear 42 and an output shaft 421;

[0023] The first gear 41 meshes with the second gear 43 , the second gear 43 is sheathed on the transmission shaft 61 , and the transmis...

Abstract

The invention discloses a gear power transfer device which comprises a shell, and the shell is provided with a plurality of heat dissipation openings; the shell is internally provided with a sound insulation chamber, a motor, a gear set and a planetary gear set assembly; the motor is arranged in the sound insulation chamber, the motor is provided with a motor output shaft, and the motor output shaft extends out of the sound insulation chamber; the motor output shaft is sleeved with a first gear; the gear set comprises a second gear, a transmission shaft, a third gear and an output shaft; and the first gear is engaged with the second gear, the second gear sleeves the transmission shaft, and the transmission shaft is fixed to the shell through a bearing seat. By means of the gear power transfer device, on one hand, design and manufacturing are facilitated; and on the other hand, the vibration reduction and noise lowering effects of a gear transmission device are achieved.

Description

technical field [0001] The invention relates to a transmission device, in particular to a gear power transmission device. Background technique [0002] Existing known planetary gears are usually composed of several planetary gear sets in series. When the number of series is more, the difficulty of assembly will also increase, and the concentricity of each planetary gear set cannot be guaranteed, which may easily cause unsmooth operation. As a result, a large noise is generated, and in serious cases, it cannot even be started. In addition, the existing power device must connect the planetary gear and the output shaft of the motor concentrically. Therefore, in applications with limited length, the overall power transmission device must be used as a The modification of the length and the reduction ratio will cause difficulties in design and manufacture, and on the other hand, it will not have the effect of shock absorption and noise reduction. [0003] Therefore, those skilled...
