Description
Technical field
The utility model belongs to motor device technical field, is related to a kind of outer rotor DC motor, more particularly to a kind of outer
Rotor electric machine motorized pulleys.
Background technology
What the country uses at present direct current drive roller was selected is that internal rotor, high rotating speed, large speed ratio planetary gear multistage subtract
Speed can be only achieved roller output and use rotating speed, and what is brought is manufacturing cost height, and it is scarce that motorized pulleys service life is short, noise is big etc.
Point.
In view of this, nowadays there is an urgent need to design a kind of new motorized pulleys, to overcome existing for existing motorized pulleys
Drawbacks described above.
Utility model content
Technical problem to be solved in the utility model is：A kind of external rotor electric machine motorized pulleys are provided, outer turn can be used
Sub- direct current generator, roller service life can be extended, reduce manufacturing cost.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of external rotor electric machine motorized pulleys, the motorized pulleys include：Barrel, external rotor electric machine, planetary gear reduction
Fast machine, drum shaft；
The planet-gear speed reducer includes：Primary planet carrier, gear ring, secondary planet frame, transition gear, one-level sun tooth
Wheel, secondary sun gear, shaft coupling；The planet-gear speed reducer is exported using gear ring, and secondary planet frame is fixed with drum shaft；
External rotor electric machine and planet-gear speed reducer are provided with the barrel, external rotor electric machine support shaft is interted with gear ring
In bearing, one-level central gear one end is interspersed in external rotor electric machine axis hole, and secondary sun gear one end is interspersed in one-level row
In carrier, secondary planet frame is set in that roller shaft end is antitorque, and secondary sun gear engages with transition gear, transition gear and gear ring
Engagement produces gear ring rotation and drives barrel to rotate.
As a kind of preferred scheme of the present utility model, one-level central gear one end turret head is interspersed in external rotor electric
In crankshaft bore hexagonal, secondary sun gear one end turret head is interspersed in primary planet carrier, and secondary planet frame is set in drum shaft
Hold antitorque on turret head.
The beneficial effects of the utility model are：The utility model proposes external rotor electric machine motorized pulleys, can use outer
