Background technology
At present, its deceleration part of motor of the planetary reduction gear high pulling torque adopted in fields such as known household electrical appliances adopts the structures such as metal ring gear, gear mostly.Tradition is applied to the planetary reducing motor in this field, because its metal internal teeth ring adopted, there is the requirement that simultaneously cannot take into account precision and cost and noise, can not meet the specific requirement of market to household electrical appliance aspect very well.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model to reduce noise and cost in conventional art.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of reducing motor, comprises the plastics internal gear that output shaft, metal collar, planetary gear pivoted arm, end cap, motor body, planetary gear and inner headed face are tooth; The two ends up and down of described metal collar connect motor body and end cap respectively and form an inner chamber, and described plastics internal gear, planetary gear pivoted arm and planetary gear are all arranged in inner chamber; Described plastics internal gear is fitted on the inwall of metal collar, and described output shaft to be plugged on end cap and rotatable, and its one end and planetary gear tumbler shaft are to being connected, and described planetary gear is plugged on the bearing pin of planetary gear pivoted arm, and engage each other with plastics internal gear.
Also comprise screw; Described metal collar is fixedly connected with by screw with end cap.
The end face of described plastics internal gear and the bottom surface of end cap all include several annular is uniform determines projection; Determine to be provided with interval between projection for adjacent two of described end cap bottom surface, the projection of determining of described plastics internal gear end face is positioned at interval.
The axial two ends of described planetary gear all include the uniform groove of several annulars.
The bottom of described motor body is provided with cooling wind blade.
The material of described plastics internal gear is nylon.
(3) beneficial effect
The utility model is compared to prior art, there is following beneficial effect: the internal gear being used as planetary reducing motor by the plastics internal gear arranging a metal collar, because the characteristic of plastic material can reduce the noise engaged between internal gear with planetary gear, and compare the cost that metal material again reduces entirety, can reduce costs when meeting instructions for use and easily produce in enormous quantities.Metal collar plays simultaneously and corrects the object that plastics internal gear loses circle, connection input/output terminal in addition.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
A kind of reducing motor as Figure 1-Figure 4, comprises the plastics internal gear 7 that output shaft 1, metal collar 2, planetary gear pivoted arm 3, end cap 4, motor body 5, planetary gear 6 and inner headed face are tooth; The two ends up and down of described metal collar 2 connect end cap 4 and motor body 5 respectively and form an inner chamber 8, and wherein the upper end of metal collar 2 adopts screw 9 to be fixedly connected with end cap 4, and described plastics internal gear 7, planetary gear pivoted arm 3 and planetary gear 6 are all arranged in inner chamber 8; Described plastics internal gear 7 is fitted on the inwall of metal collar 2, described output shaft 1 to be plugged on end cap 4 and rotatable, its one end is axially connected with planetary gear pivoted arm 3, and described planetary gear 6 is plugged on the bearing pin of planetary gear pivoted arm 3, and engages each other with plastics internal gear 7.The plastics internal gear that the utility model have employed a metal collar is used as the internal gear of planetary reducing motor, concrete plastics can be nylon high-abrasive material, because the characteristic of plastic material can reduce the noise engaged between internal gear 7 with planetary gear 6, and compare the cost that metal material again reduces entirety, can reduce costs when meeting instructions for use and easily produce in enormous quantities.Metal collar plays simultaneously and corrects the object that plastics internal gear loses circle, connection input/output terminal in addition.
The end face of described plastics internal gear 7 and the bottom surface of end cap 4 all include several annulars uniform fixed protruding 10; Determine between projection, to be provided with interval 11 for adjacent two of described end cap bottom surface, fixed protruding 10 of described plastics internal gear 7 end face is positioned at interval 11, because metal collar 2 and end cap 4 are fixedly linked to adopt screw 9, so when fixed protruding 10 are positioned at interval 11, described plastics internal gear 7 would not by planetary gear 6 driven rotary, so can not impact deceleration
As shown in Figure 2, the axial two ends of planetary gear 6 described in figure all include the uniform groove 12 of several annulars, and this structure can save material, thus reduces the cost of manufacture of planetary gear 6.
The bottom of described motor body 5 is provided with cooling wind blade 13, is convenient to motor body 5 and dispels the heat.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
