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

[0016] Below in conjunction with accompanying drawing and embodiment

[0017] The present invention is described further:

[0018] Such as figure 1 As shown, a gear transmission device includes a housing 60, which is provided with several heat dissipation ports; a soundproof room, a motor 30, a gear set 40 and a planetary gear set assembly 50A are arranged in the housing 60;

[0019] 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 .

[0020] The gear set 40 includes a second gear 43, a transmission shaft 61, a third gear 42 and an output shaft 421;

[0021] The first gear 41 meshes with the second gear 43 , the second gear 43 is sheathed on the transmission shaft 61 , and the transmi...

Abstract

The invention discloses a gear transmission device. The gear transmission device comprises a shell. The shell is provided with a plurality of heat dissipation ports. A sound isolation chamber, a motor, a gear set and a planet gear set assembly are arranged in the shell. The motor is arranged in the sound isolation chamber and provided with a motor output shaft, and the motor output shaft extends out of the sound isolation 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. The first gear is meshed with the second gear. The second gear is arranged on the transmission shaft in a sleeving manner. The transmission shaft is fixed to the shell through a bearing block. On one hand, designing and manufacturing are facilitated, and on the other hand, the gear transmission device has the beneficial effects of achieving damping and noise reducing.

Description

technical field [0001] The invention relates to a transmission device, in particular to a gear 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 in th...
