Planetary gear rotation in its inside under sun gear drive is realized, and can be realized in the case where sun gear does not turn to planet tooth
The locking of wheel active rotation, it is to avoid rotation of the planetary gear under output sector gear drive, has thoroughly prevented input and defeated
The drawbacks of going out to hold equidirectional rotation and self-locking cannot be realized.
Described multiple planetary gears are rotatably installed on planet frame plate by planetary gear bearing pin.Multiple planetary gears are used as biography
Dynamic component is rotatably arranged on the inside of output sector gear and retaining mechanism, can simultaneously with output sector gear and lock machine
There is engagement in the inner side of structure, you can realize rotating along inwall in retaining mechanism, output sector gear can be driven again to rotate, to output
End output power, while, moreover it is possible to a, fixed installation movable using output sector gear and retaining mechanism one, and while all
The version being connected with planetary mechanism engagement realizes auto-lock function.
On the described uniform planet carrier plate of multiple planetary gear annulars.
Described planet frame plate is provided with symmetrical two group, and two groups of planet frame plates connect the two of described planetary gear bearing pin respectively
End.
Described meshing gear output mechanism includes floating internal gear and power output shaft, and floating internal gear is by annular
Internal tooth on wall is sleeved on the outside of planetary mechanism, the center connection power output shaft of floating internal gear end face.
The inner face of described floating internal gear is provided with the bearing for rotating connection sun wheel end.
Centered on described retaining mechanism, place is fixedly set in the fixed annulus on input shaft.
Compared with prior art, this utility model is had an advantageous effect in that：
1st, auto-lock function is realized, and auto-lock function is preferably, changes the structure of existing planetary gear reducing mechanism, will be conventional
It is sleeved on the interior tooth engaging conformation outside planetary mechanism and is divided into suspension and fixed two parts, that is, the output sector gear of the installation that suspends
The retaining mechanism being fixedly installed with one end, inside the multiple planetary gears of power intake engagement connection, clutch end engagement connects
Multiple planetary outsides are connect, meanwhile, break-in is realized using the relative rotation between planetary mechanism and sun gear so that output
Steering and input direction conversely, simultaneously as retaining mechanism is fixedly installed and with internal tooth, is meshed with planetary gear, it is right
Planetary gear and planet frame plate are positioned, and can realize planetary gear rotation in its inside under sun gear drive, and energy
Realize the locking in the case where sun gear does not turn to planetary gear active rotation, it is to avoid planetary gear is in output sector gear band
Rotation under dynamic, the drawbacks of thoroughly having prevented input and the equidirectional rotation of outfan and self-locking cannot have been realized.And due to which certainly
The characteristics of body mechanism, experiment is learnt, its auto-lock function is higher than the self-locking degree of worm and gear gear-box and brake device.
2nd, product cost is saved, traditional planetary reducer is with the increasing of fast ratio, it is necessary to be continuously increased gear stage
Number, and this product then needs primary planet wheel, a sun gear, two-stage internal gear just to produce conventional planetary decelerator 3-4 levels gear institute
The speed ratio of generation.
3rd, load capacity is big.
4th, because need to be few with gear, than conventional planetary gear decelerator（Planet-gear speed reducer）More save space, from body
Product is less.
