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

[0017] Below in conjunction with the drawings and embodiments

[0018] To further explain the present invention:

[0019] Such as figure 1 As shown, a gear power transmission device with noise reduction function includes a housing 60 with a number of heat dissipation ports; a soundproof chamber, a motor 30, a gear set 40 and planetary gears are provided in the housing 60 Group assembly 50A;

[0020] The motor 30 is arranged in a soundproof room, and a motor output shaft 31 is arranged on the motor 30, and the motor output shaft 31 extends out of the soundproof room (not shown in the figure); in order to improve the sound insulation effect, the soundproof room is composed of six asbestos soundproof boards. A first gear 41 is sleeved on the motor output shaft 31.

[0021] The gear set 40 includes a second gear 43, a transmission shaft 61, a third gear 42, and an output shaft 421;

[0022] The first gear 41 meshes with the second gear 43, the second gear 43 is sleeved on the transmissio...

Abstract

The invention discloses a gear power transmission device with a noise reduction function, which comprises a housing on which several heat dissipation ports are opened; a soundproof room, a motor, a gear set and a planetary gear set assembly are arranged in the housing; the motor It is installed in the soundproof room, the motor is provided with a motor output shaft, and the motor output shaft extends out of the soundproof room; the first gear is set on the motor output shaft; the gear set includes the second gear, the transmission shaft, the third gear and the output shaft; A gear meshes with a second gear, the second gear is sleeved on the transmission shaft, and the transmission shaft is fixed on the casing through a bearing seat. On the one hand, the present invention is convenient for design and manufacture, and on the other hand, it has the effects of shock absorption and noise reduction of the gear transmission.

Description

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