When moving and rotating counterclockwise, lubrication groove 7 and 8 movement interference of outer ring are not resulted in.
As shown in figure 3, in embodiment one and embodiment two, as lubrication groove 7, turning collar 6 and outer ring 8 are same successively
The heart is arranged, so need spring bearing 22 is installed between lubrication groove 7 and turning collar 6, between turning collar 6 and outer ring 8, for supporting
Therebetween；This is designed to radial-play between guarantee lubrication groove 7 and turning collar 6, between turning collar 6 and outer ring 8,
And the rotation between the rotation between without prejudice to lubrication groove 7 and turning collar 6 and turning collar 6 and outer ring 8.
As shown in figure 4, in embodiment three, the first unidirectional joint portion 4 includes first be arranged on the periphery of lubrication groove 7
Wedge-shaped indentation, first roll post 16 and the first spring spindle 17, and the first wedge-shaped indentation is internally formed one first with turning collar 6
Wedge gap 15, one end space of the first wedge gap 15 is larger and other end space is less, and first to roll post 16 axially arranged
In the first wedge gap 15, the first spring spindle 17 has the elastic force of the axial direction of very little, and which is arranged in the first wedge-shaped indentation,
One end is connected with lubrication groove 7 and the other end is contradicted and rolled on post 16 first, and the first rolling post 16 is pushed up to the first wedge gap
The less one end of 15 voids；The second wedge-shaped indentation that second unidirectional joint portion 5 includes being arranged on the periphery of turning collar 6,
Second rolls post 19 and second spring push rod 20, and the second wedge-shaped indentation is internally formed the second wedge gap 18 with turning collar 6, the
One end space of two wedge gaps 18 is larger and other end space is less, and the second rolling post 19 is axially disposed within the second wedge gap
In 18, second spring push rod 20 has the elastic force of the axial direction of very little, and which is arranged in the second wedge-shaped indentation, and one end is connected with lubrication groove 7
Connect and the other end is contradicted and rolled on post 19 second, and the second rolling post 19 is pushed up less to 18 void of the second wedge gap
One end.
It is positive movement in a counterclockwise direction, clockwise for during adverse movement；When power unit drives turning collar 6,
And when turning collar 6 is rotated in the counterclockwise direction, first rolls the frictional force and first that post 16 is subject to the inner headed face of turning collar 6
Under the elastic force effect of spring spindle 17, roll to the less one end of 15 void of the first wedge gap, and be stuck in the inside, so as to logical
Cross frictional force turning collar 6 is stuck with lubrication groove 7, lubrication groove 7 is rotated counterclockwise with turning collar 6, second rolls post 19
By the frictional force effect of the inner headed face of outer ring 8, overcome the elastic force of second spring push rod 20, and roll in the second wedge gap 18
The larger one end in space, and also as the inner headed face rolling of outer ring 8, now outer ring 8 is separated with turning collar 6；When power unit drives
Dynamic turning collar 6, and when being rotated in the clockwise direction turning collar 6, second rolls the frictional force that post 19 is subject to the inner headed face of outer ring 8
And under the elastic force effect of second spring push rod 20, roll to the less one end of 18 void of the second wedge gap, and in being stuck in
Turning collar 6 is stuck with outer ring 8 by face so as to pass through frictional force, outer ring 8 is rotated clockwise with turning collar 6, and first
The frictional force effect that post 16 is subject to the inner headed face of turning collar 6 is rolled, the elastic force of the first spring spindle 17 is overcome, and is rolled to first wedge
The larger one end of 15 void of shape gap, and also as the inner headed face rolling of turning collar 6, now lubrication groove 7 is separated with turning collar 6；
This is designed to make turning collar 6 drive lubrication groove 7 to rotate when rotating counterclockwise, and drives outer ring 8 to rotate when rotating clockwise, and nothing
During by rotating clockwise and rotate counterclockwise, lubrication groove 7 and 8 movement interference of outer ring are not resulted in.
Presently preferred embodiments of the present invention is the foregoing is only, is merely illustrative for the purpose of the present invention, and it is non-limiting
