Through setting up first strengthening rib to make second boss and first boss link together, so that the power that the output shaft received can be better through first bearing, first boss, second boss in order to transmit to the mount on, with the amplitude of rocking and the noise that further reduces the reducing gear box.

Preferably, the height of the end, close to the second boss, of the first reinforcing rib is greater than the height of the end, close to the first boss, of the first reinforcing rib, and the reinforcing rib is of a trapezoidal structure or a triangular structure. The height of the joint of the first reinforcing rib and the second boss is larger than that of the joint of the first boss, so that the second boss is not easy to damage and crack, and the reduction gearbox is more stably connected and fixed with the fixing frame.

As preferred, the speed reduction unit includes input gear, linkage gear and output gear, the input gear cover establish fix on the input shaft and with linkage gear engagement, linkage gear and linkage shaft are fixed and with output gear engagement, the output gear cover is established on being fixed in the output shaft, be equipped with the second bearing room that is used for fixed second bearing in the box, the bottom of second bearing room forms the third boss to the outside protrusion of box, the linkage shaft front end passes through second bearing rotation support in the second bearing room, be equipped with the third bearing room that is used for fixed third bearing in the case lid, the bottom of third bearing room forms the fourth boss to the outside protrusion of case lid, the linkage shaft rear end passes through third bearing rotation support in the third bearing room, the second boss is higher than the fourth boss.

Wherein, a part of second bearing room is located the third boss to make box inner space littleer, a part of third bearing room is located the fourth boss, so that the reducing gear box volume is littleer, under the condition of adding equivalent lubricating oil, enables the utility model discloses the lubricated effect of speed reduction subassembly in the reducing gear box is better, in order further to reduce the utility model discloses noise when the reducing gear box uses.

Preferably, a plurality of second reinforcing ribs are connected between the side wall of the fourth boss and the end face of the box cover, and the second reinforcing ribs are arranged at equal intervals in an annular mode with the axis of the fourth boss as the center. Through setting up the second strengthening rib to make the fixed intensity of fourth boss and case lid higher, the power that the output shaft bore simultaneously can be transmitted for the case lid through output gear, linkage gear, universal driving shaft, and then transmits for the mount, in order to further reduce the reducing gear box range of rocking.

The utility model has the advantages of it is more stable to enable gear motor is fixed to noise and increase of service life when reducing the use.
