Abstract
The utility model discloses a planetary gear speed reduction electric motor, comprising an electric motor and a planetary gear speed reducer. The utility model is characterized in that the driving cap of the electric motor is directly connected with the internal gear of the speed reducer, an input-gear fixed to the output shaft of the electric motor is engaged with the planetary gear of the speed reducer, and the planetary gear is engaged with the internal gear. The intermediate connection cap of the speed reducer is removed by the utility model, the electric motor is in a direct connection with the speed reducer, with a compact conformation, and the electric motor and the speed reduction part are integrated. The axial length of the speed reducer is reduced, the positioning accuracy of the electric motor and the speed reducer are improved, and the noise of the product is reduced, with the improvement of the performance of the product. The connection cap is removed, the components are decreased, and the volume is reduced, with the reduction of the cost.
Description
Technical field
The utility model relates to a kind of decelerator.
Background technology
The decelerator of prior art is that existing planetary reducer is connected with motor, and connected mode is by middle connection cover the internal gear of motor and decelerator to be coupled together.Because other decelerators are longer relatively for the axial length of planetary reducer, thereby the positioning accuracy that is connected with motor is relatively low, noise is big.
Summary of the invention
The Planetary Gear head Motor that technical problem to be solved in the utility model provides, the positioning accuracy height, noise is low.
Planetary Gear head Motor of the present utility model, comprise motor and planetary reducer, it is characterized in that the driving lid of motor and the internal gear of decelerator directly are connected, the output shaft of motor is provided with the input gear, the planetary gear engagement of input gear and decelerator, planetary gear and internal gear engagement.
The utility model removes the middle connection cover of decelerator, and motor and decelerator are direct-connected, compact conformation, motor and deceleration part be one each other, and the axial length of decelerator reduces, and has improved the positioning accuracy of motor and decelerator, reduce the product noise, improved properties of product.Remove connection cover, part has been reduced, volume has alleviated, and has also reduced cost.
Other structures, especially planetary reducer that the utility model does not change motor and decelerator have just removed its middle connection cover (end cap), and its internal structure is as prior art.The utility model is by motor and the direct-connected Planetary Gear head Motor that forms of decelerator, power be by the input gear (with motor shaft be one) pass to planetary gear, planetary gear passes to output shaft, realizes transmission of power.Deceleration part is made up of input gear, planetary gear, stepped gear (during multistage transmission with), internal gear and output shaft.Internal gear is that the shell of decelerator maintains static.
Advantage of the present utility model:
Designs simplification, volume reduces, and has reduced cost; The positioning accuracy height, noise reduces, and has improved properties of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 motor, 2 steady pins, 3 motor-driven are covered 4 motor output shafts and input gear 5 planetary gears 6 oiliness bearings 7 rivets 8 internal gears 9 bearings 10 forward flanges 11 holes back-up ring 12 shaft block rings 13 output shafts
Embodiment
Motor output shaft is provided with the input gear, and input gear and motor output shaft are fixed as one.Motor-driven lid 3 directly is connected (can fix by bearing pin, not shown) with the internal gear 8 of decelerator part.The structure of decelerator is a known structure, and planetary gear can be made up of one or more levels.The input gear 4 of motor (with the motor output shaft one) meshes with the planetary gear 5 of decelerator, planetary gear 5 and internal gear 8 engagements, and internal gear 8 maintains static for the shell of decelerator.
Power of the present utility model is to give planetary gear by the input gear transmission, and planetary gear passes to output shaft 13, realizes transmission of power.Deceleration part is made up of input gear 4, planetary gear 5, internal gear 8 and output shaft 13.
