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
The present invention relates to a kind of transmission device, particularly relate to a kind of gear transmission device.
Background technique
Existing known planetary pinion is normally composed in series by several planetary gear set, when serial number is more, the difficulty of assembling also improves thereupon, and the concentricity of each planetary gear set cannot be ensured, easily cause the situation operating and have some setbacks, thus produce larger noise, time serious, even cannot start, in addition planetary pinion and motor output shaft must must be that concentric type is connected by existing power plant, therefore in the middle of the application of finite length, just integral power transmission device must be done the correction of length and reduction speed ratio, difficulty on design and manufacture will be caused thus, the effect of damping and noise reduction is not possessed on the other hand yet.
Therefore those skilled in the art are devoted to develop a kind of actuating unit increasing assembling convenience.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of actuating unit increasing assembling convenience.
For achieving the above object, the invention provides a kind of gear transmission device, comprise housing, in housing, be provided with motor, gear train and planetary gear set assembly;
Motor is provided with motor output shaft, motor output shaft is arranged with the first gear;
Gear train comprises the 3rd gear and output shaft;
First gear and the 3rd gears meshing, the 3rd geared sleeve is located on output shaft, and the output terminal of output shaft is connected with central shaft, and the output terminal of central shaft is connected with planetary pinion output shaft;
Planetary gear set assembly comprises several planetary gear set be connected in series, driving gear and internal gears;
Planetary pinion comprises driving arm, several planetary pinions and planet axis;
Each planetary pinion engages with internal gear and driving gear simultaneously, and driving gear is set on the output terminal of output shaft;
Planetary pinion is set in planet axis, and planet axis is connected with driving arm, and driving arm serial connection on center shaft; Planet axis and driving arm Spielpassung.
In order to motor vibrations operationally can be effectively reduced, motor is arranged with shock absorbing sleeve.
The invention has the beneficial effects as follows: one aspect of the present invention is convenient on design and manufacture on the other hand, possessed the effect of gear drive damping and noise reduction.
