Specific embodiment
Embodiment one (buffer stopper is arranged on the sidepiece outer wall of single retarded device barrel cover)
As shown in figure 1, a kind of unidirectional planetary reduction gear with buffer unit of starter, including non-return device, deceleration
Device and an extra shell 7, described deceleration device is planetary reducer, including planetary reduction gear ring gear 1, is characterized in：
Also include buffer unit, described buffer unit includes 9, buffer stopper 4 of chuck in No. of an extra shell 7 inwall end
And it is arranged on an extra chuck 8 on single retarded device case 5 outer wall, a described single retarded device case 5
In an extra shell 7, as depicted in figs. 1 and 2, a hole 10 on a described buffer stopper 4 is enclosed within an extra chuck 8,
And in being located at two No. one between chuck 9；
Described non-return device includes a single retarded device case 5 and friction stopping device；A described single retarded
Device case 5 is in tubbiness, and its inwall is provided with flexible roller groove 6, and its outer wall is provided with an extra chuck 8；Described No. one unidirectional
Deceleration device housing 5 is enclosed within planetary reduction gear ring gear 1；Described friction stopping device is included in flexible roller groove 6
Spring 2 and the outer wall of roller 3 and planetary reduction gear ring gear 1；Described spring 2 one end is against on flexible roller groove 6 side wall, another
End withstands roller 3 by spring base or directly；Ramped shaped is made in the bottom of flexible roller groove 6, and it is with planetary reduction gear internal tooth
Enclose the distance between 1 outer wall and form gradual change gap.
Embodiment two (buffer stopper is arranged in the bottom outer wall of single retarded device barrel cover)
As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of unidirectional planetary reduction gear with buffer unit of starter, including
Non-return device and deceleration device, described deceleration device is planetary reducer, including planetary reduction gear ring gear 1, its feature
It is：Also include buffer unit, described buffer unit include chuck 9-1 in No. two of inwall in the middle part of two extra shell 7-1, No. two
Buffer stopper 4-1 and two extra chuck 8-1 being located at No. two single retarded device case 5-1 bottom outer wall, described No. two unidirectional to subtract

Operation principle with embodiment one：
During utility model works, work as power on, when motor rotary shaft drives starter driving shaft to rotate, No. one unidirectional
Deceleration device housing 5 is subject to an impulsive force, and this power acts on a buffer stopper 4, make a single retarded device case 5 with
One extra shell 7 avoids rigid contact, substantially reduces the harm that impact brings, extends the service life of starter；
When planetary reduction gear ring gear 1 counterclockwise rotates, a single retarded device case 5 is motionless, and roller 3 is rubbing
In the presence of wiping power, extrusion spring 2 rolls in the wide gap of flexible roller groove 6 (more than the diametrical position of roller 3), and now, planet subtracts
The braking of fast device ring gear 1 is released from, and with planetary gear rotation, is in clutch state, will not transmit torque to motor.
When planetary reduction gear ring gear 1 is rotated clockwise, a single retarded device case 5 is motionless, and roller 3 is in bullet
It is squeezed in the narrow gap of flexible roller groove 6 (less than the diametrical position of roller 3) planetary reduction gear in the presence of spring 2 auxiliary and frictional force
Device ring gear 1 is by the stuck braking of roller 3.Now, the torque of one-way transmission motor.
