Abstract
The invention discloses a speed reducing mechanism for a low-starting current motor. The speed reducing mechanism is a planet speed reducing mechanism and comprises a gear ring, a planet carrier, a planet wheel and a sun wheel, wherein the gear ring is connected with a flange of an end cover of a motor; the planet wheel is respectively engaged with the gear ring and the sun wheel; the sun wheel is connected with a driven wheel of a gravity centrifugal magnetic clutch and the sun wheel is rotatably matched with an output shaft of the motor; the planet carrier is connected with the planet wheel through a planet gear shaft; and the planet carrier is sleeved on the output shaft of the motor to drive the output shaft to rotate. According to the invention, the motor is internally provided with a planet speed reducing mechanism and an inner space of a hollow motor is sufficiently utilized; the sun wheel and the driven wheel are integrally molded and the gear ring is connected with the flange of the end cover; an enough space is remained in a rotor of the motor to reasonably mount the planet speed reducing mechanism, so that the volumes of the motor, a clutching mechanism and a transmission mechanism are reduced, and the unexpected effects of reducing the production cost, saving energy and reducing emission can be realized.
Description
Technical field
The present invention relates to the drive of motor technical field, particularly a kind of reducing gear that is used for the low starting current motor.
Background technology
At present at electromechanical integration motor and transmission field, connect complicated, bulky between motor and the transmission mechanism; The transmission power loss is many, and the electric current when motor starts under rated voltage, rated frequency generally is several times as much as rated current; Starting current is 4 times to 7 times of rated current; Big starting current can cause that the motor feels hot, can cause the fluctuation of network voltage, influences the normal use of power consumption equipment.
Just need a kind of simple in structure, starting current is little, the transmitted power loss is little low starting current motor this moment, use better and energy savings to help people.
The special centrifugal magnetic clutch of gravity that in motor, is provided with; Make electric motor starting at no-load condition, the little nothing overload of starting current possibility, the centrifugal magnetic clutch of gravity comprises driving wheel and the driven pulley that is sealed and matched; When motor speed reaches normal speed; The centrifugal magnetic clutch work of gravity, driving wheel drives driven pulley and rotates, and drives output shaft again and rotates.Final purpose is that motor starts at no-load condition, has reduced the electric motor starting electric current, has guaranteed its useful life, conservation of power.If but the rotation of driven pulley direct drive motor output shaft then can't obtain suitable moment of torsion, generally reducing gear need be set, if reducing gear is too huge, then can take larger volume, increases cost, so the setting of reducing gear is outbalance also.
Summary of the invention
The present invention is directed to the deficiency that exists in the above-mentioned prior art, a kind of saving volume is provided, reduce cost, make output shaft can export the reducing gear of suitable rotating speed, balanced torsion.
Technical scheme of the present invention is achieved in that
A kind of reducing gear that is used for the low starting current motor; Described reducing gear is a planetary gear speed reducing mechanism; It comprises gear ring, planet carrier, planetary gear and sun gear, and said gear ring is connected with the end cap flange of motor, and said planetary gear meshes with gear ring, sun gear respectively; Described sun gear links to each other with the driven pulley of the centrifugal magnetic clutch of gravity; And sun gear and motor output shaft are rotatably assorted, and described planet carrier links to each other through planet pin with planetary gear, and planet carrier is socketed on the motor output shaft and drives output shaft and rotates.
As preferably, described planet carrier links to each other with motor output shaft through spline.
As preferably, the end cap flange interference fit of said gear ring and motor.
Adopted the principle of the present invention and the beneficial effect of technique scheme to be:
Be provided with planetary gear speed reducing mechanism in the motor of the present invention; Make full use of the core motor inner space, sun gear and driven pulley are formed in one, gear ring links to each other with the end cap flange; Enough spaces are left in rotor inside; Planetary gear speed reducing mechanism is rationally installed, reduced the volume of motor and clutch and transmission mechanism, played and reduced production cost and energy savings and reduced the beyond thought effect of discharging.

Embodiment
Embodiment of the present invention is following:
Embodiment: a kind of reducing gear that is used for the low starting current motor of the present invention; Described reducing gear is a planetary gear speed reducing mechanism, and shown in Fig. 1～2, it comprises gear ring 27, planet carrier 23, planetary gear 25 and sun gear 60; Said gear ring 27 is connected with end cap flange 9; Said planetary gear 25 respectively with 60 engagements of gear ring 27, sun gear, described sun gear 60 is one-body molded with the driven pulley 28 of the centrifugal magnetic clutch of gravity, and the output shaft of sun gear 60 and motor 1 is rotatably assorted through bearing; Described planet carrier 23 links to each other through planet pin 24 with planetary gear 25, and planet carrier 23 is connected on the output shaft 1 through spline housing and drives output shaft 1 and rotates.
The moment of torsion that input current produces drives rotor 30 high speed rotating, drives the planetary gear speed reducing mechanism rotation and export through the centrifugal magnetic clutch of gravity to be fit to the equal permanent moment of torsion of rotating speed.
