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 the accompanying drawings and embodiments

[0019] The present invention is further described:

[0020] like figure 1 As shown, a gear structure includes a housing 60, which is provided with several heat dissipation ports; the radius of the heat dissipation port is 5 cm; a soundproof room, a motor 30, a gear set 40 and a planetary gear are arranged in the housing 60 Group assembly 50A;

[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 o...

Abstract

The invention discloses a gear structure. The gear structure comprises a shell, and a plurality of radiating openings are formed in the shell; a sound-proof room, a motor, a gear set and a planetary gear set assembly are arranged in the shell; the motor is arranged in the sound-proof room, and a motor output shaft is arranged on the motor and extends out of the sound-proof room; 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 meshed with the second gear, the second gear is arranged on the transmission shaft in a sleeving manner, and the transmission shaft is fixed to the shell through a bearing base. By means of the gear structure, on one hand, convenience is brought to design and manufacturing; and on the other hand, the damping and noise reduction effects of the 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...
