Abstract
The utility model discloses a low-speed motor. The low-speed motor includes a motor body and a speed-reducing device; the top surface of the motor body is fixedly provided with an annular gear ring which surrounds a motor output shaft of the motor body; the motor output shaft is fixedly provided with a sun wheel; the speed-reducing device comprises an upper cover and a transmission shaft; the bottom surface of the transmission shaft is circumferentially provided with a plurality of pin shafts; each pin shaft is rotatingly provided with a planet wheel respectively; the planet wheels are respectively engaged with the sun wheel and the annular gear ring; the top surface of the transmission shaft is provided with a step shaft which is small at an upper portion and is big at a lower portion; the upper end of the transmission shaft extends upwards and passes through the upper cover; the large-diameter portion of the step shaft is provided with a first bearing; and a small-diameter portion of the step shaft is provided with a second bearing. According to the low-speed motor of the utility model, high-speed rotation outputted by the motor body is subjected to speed changing of a planet device formed by the sun wheel, the planet wheels and the annular gear ring, and thereafter, is outputted by the transmission shaft supported by the first bearing and the second bearing, and therefore, the output rotation speed of the transmission shaft is low and stable.
Description
Technical field
The utility model relates to motor, is specifically related to slowspeed machine.
Background technology
Be widely used slowspeed machine on the small household appliances such as electric squeezer, its objective is the stationarity of acquisition electric machine rotation output and larger squeeze force.Yet, the problem that slowspeed machine ubiquity transmission in the market is not steadily, noise is large.
The utility model content
Technical problem to be solved in the utility model is the problem that the slowspeed machine transmission is steady, noise is large.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of slowspeed machine, comprise motor body and deceleration device, motor output shaft around described motor body on the end face of described motor body is fixed with an annular gear ring, be fixed with a sun gear on described motor output shaft, described deceleration device comprises upper cover and power transmission shaft, on the bottom surface of described power transmission shaft, edge circumferentially is laid with many bearing pins, rotate and be provided with a planetary gear respectively on every described bearing pin, described planetary gear meshes with described sun gear and described annular gear ring respectively, the end face of described power transmission shaft is provided with a up-small and down-big Step Shaft, the upper end of described power transmission shaft upwards passes described upper cover, and the major diameter section of described Step Shaft is provided with clutch shaft bearing, and minor diameter is provided with the second bearing.
In such scheme, the upper end of described the second bearing is by jump ring axial restraint on the minor diameter of described Step Shaft.
In such scheme, described upper cover has up-small and down-big stepped hole, the major diameter section of described stepped hole and the outer ring of described clutch shaft bearing are suitable, the outer ring of the minor diameter of described stepped hole and described the second bearing is suitable, and the step surface of described stepped hole and the upper surface of described clutch shaft bearing offset, make described clutch shaft bearing axial restraint.
In such scheme, the quantity of described bearing pin is three.
In such scheme, the external diameter of described annular gear ring is less than the external diameter of described motor body, and described upper cover is bolted on described motor body by many, and described bolt is around the uniform setting of the outer circumference surface of described annular gear ring.
The utility model, the high speed rotating of motor body output, after the planet device speed change formed by sun gear, planetary gear and annular gear ring, then by the power transmission shaft output of first, second bearings, thereby make the output speed low speed of power transmission shaft, steadily.
The accompanying drawing explanation
Fig. 1 is profile schematic diagram of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is profile of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, Figure 2 and Figure 3, the slowspeed machine that the utility model provides, comprise motor body 10 and deceleration device 20.
The utility model, install two bearings additional and jump ring has carried out good location with fixing by rotation axis at the upper cover of original motor, solved when power transmission shaft rotates axially and circular runout, solved the slowspeed machine transmission not steadily, the problem such as noise is large.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
