Description
Technical field
The present invention relates to a kind of actuating device, particularly relate to a kind of gear-box sound arrester.
Background technology
Existing known planetary gear is usually composed in series by several planetary gearsets, when serial number is more many, the difficulty assembled also improves therewith, and the concentricity of each planetary gearsets cannot be ensured, easily cause the situation that operating has some setbacks, thus producing bigger noise, time serious, even cannot start, in addition planetary gear and motor output shaft must must be that concentric type is connected by existing power set, therefore in the middle of the application scenario of finite length, it is necessary for making integral power actuating device the correction of length and speed reducing ratio, difficulty on will result in design thus and manufacturing, do not possess the effect of damping and noise reduction on the other hand yet.
Therefore those skilled in the art are devoted to develop a kind of actuating unit increasing and assembling convenience.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of actuating unit increasing and assembling convenience.
For achieving the above object, the invention provides a kind of gear-box sound arrester, including housing, in described housing, be provided with soundproof room, motor, gear train and planetary gearsets assembly；
Described motor is arranged in described soundproof room, and described motor is provided with motor output shaft, and described motor output shaft extends described soundproof room；Described motor output shaft is arranged with the first gear；
Gear train includes the 3rd gear and output shaft；
First gear and the engagement of the 3rd gear, the 3rd geared sleeve is located on output shaft, and the outfan of output shaft is connected to central shaft, and the outfan of central shaft is connected to planetary gear output shaft；
Planetary gearsets assembly includes the planetary gearsets of several concatenations, travelling gear and internal gear；
Planetary gear includes driving arm, several planetary gears and planet axis；
Each planetary gear is simultaneously engaged with internal gear and travelling gear, and travelling gear is set on the outfan of output shaft；
Planetary gear is set in planet axis, and planet axis is connected with driving arm, drives arm to concatenate on center shaft；Planet axis and driving arm matched in clearance.
In order to effectively reduce motor vibrations operationally, motor is arranged with shock-absorbing sleeve.
In order to improve soundproof effect, described soundproof room is made up of six pieces of asbestos baffles.
The invention has the beneficial effects as follows: on one aspect of the present invention is easy to design and is manufactured, on the other hand, possessed the effect of gear drive damping and noise reduction.
Accompanying drawing explanation
