Exchange, sliding is adopted on the basis of cylinder gear speed reducer, connect the forms such as gear to realize speed change, the change used by automobile
Fast device its complex structure is only suitable for automotive field, and in the very big planetary reduction gear of mechanical transmission fields accounting only at present
There is a kind of speed ratio, so need this decelerator of the occasion of conversion speed and moment of torsion just to receive restriction at some.The present invention exists
On the basis of this new invention it is a kind of can the step speed change planetary reduction gear of commutation instants speed and moment of torsion only solve on market
Planetary reduction gear this difficult problem of single transmission ratio.
The content of the invention
It is an object of the invention to provide a kind of step speed change planetary reduction gear.
In order to achieve the above object, the technical solution used in the present invention is：
It is fixed by screws on shell body including input flange end cap and is connected with electric magnet, electric magnet endoporus is provided with circle
Post helical spring, armature are connected with one-level ring gear by screw, and one-level ring gear is engaged with primary planet pinion, is sleeved on master
One-level sun wheel drive primary planet pinion on axle is equipped with two grades of sun so as to drive primary planet carrier, primary planet carrier end
Wheel, secondary solar gear are engaged with secondary planet wheel, and secondary planet wheel drives secondary planet frame, secondary planet frame end portion that three-level is housed
Sun gear, three-level sun gear are engaged with third-level planetary wheel, and third-level planetary wheel drives third-level planetary frame, output shaft and third-level planetary frame
Connection, is provided with support of the seam back-up ring by output flange inner bearing on output shaft, bearing outer ring is pushed down by bearing gland,
Key is installed on output shaft.Variable moderator main shaft input end is sealed by sealing ring, and output shaft is sealed by sealing ring.
