Boss length in axial direction and equal to blind hole 10-3 depth and thrust pin-and-hole 6-2-8 depth sums, hemispherical head 6-5-5's is straight
Footpath is slightly less than the internal diameter of blind hole 10-3 in remote gear side fixed plate 2-2.
Claw 6-2-1, which is located on the spring positioning table 6-2-5 of side clockwise, is provided with pressure sensor, you can dynamic claw
6-3 sides contact the return spring of side with clutch plate locking groove 6-2-2 groove faces in itself and spring positioning table 6-2-5 contact positions
Pressure sensor is provided with, the change to detect the end spring pressure, i.e., the end at the spring in pressured state in reversion
End is installed by pressure sensor.When axle is inverted, the pressure sensor being connected with spring is capable of the change of detection spring reversion stress
And alarm, it is further processed by staff.
Operation principle：
During normal operation：Multi-diameter shaft 1 rotates, the gear 5 and driving disc spacing pressing 6-1 coordinated with multi-diameter shaft 1 by key connected mode
With rotation, the clutch plate 6-2 coordinated with multi-diameter shaft 1 by the capping 6-6 of bearing fit and gap does not rotate.Driving disc spacing pressing 6-1
Before rotation, i.e., before multi-diameter shaft 1 rotates, the hemispherical head 6-5-5 of thrust pin 6-5 one end is located at the blind hole 10-3 of remote gear cant board 10
In, the hemispherical head 6-5-5 of the thrust pin 6-5 other ends is located at clutch plate 6-2 thrust pin slideway 6-2-9, on thrust pin 6-5
Spring 6-5-2 the hemispherical head 6-5-5 of thrust pin slideway 6-2-9 sides is stretched into by movable claw main part 6- due to thrust pin
The spacing of 3-3 is in compressive state；Movable claw 6-3 and clutch plate locking groove 6-2-2 groove side single-contact.
After multi-diameter shaft 1 rotates a certain angle, the pawl groove 6-1-2 and movable claw 6-3 on driving disc spacing pressing 6-1 progressively connects
Touch, movable claw 6-3 under the pawl groove 6-1-2 of driving disc spacing pressing drive clutch plate 6-2 locking groove 6-2-2 along arc to rotation
Turn.Due to movable claw 6-3 sides and the one-side contact of locking groove 6-2-2 groove faces, so that movable claw 6-3 is in locking groove
Unidirectional during 6-2-2 motion, movable claw 6-3 can not be after by the stop of locking groove 6-2-2 grooves side during counter motion
Reforwarding is moved, and this guarantees the directional rotating function of gear.Due to thrust pin 6-5 circumferentially direction without motion, movable claw
When 6-3 circumferentially rotates, the relative position of the two changes, under original state thrust pin hemispherical head 6-5-5 with it is movable
Claw main part 6-3-3 contact is changed into hemispherical head 6-5-5 and contacted with movable claw 6-3 through hole 6-3-4, and with master
Moving plate 6-1 continuation rotation, thrust pin 6-5 is gradually increased until hemispherical head with the movable claw 6-3 through-hole aperture 6-3-4 contacted
6-5-5 can be stretched into the through hole 6-3-4 of movable claw under spring 6-5-2 promotions.When thrust pin hemispherical head 6-5-2 is stretched into can
During dynamic claw 6-3 through hole 6-3-4, the hemispherical head of the thrust pin 6-5 other end is from the blind hole in fixed remote gear riser 10
Withdrawn from 10-3, now thrust pin 6-5 is fully located at clutch plate 6-2 thrust pin slideway 6-2-9 and two of movable claw are led to
Hole 6-3-4 centre position so that be inserted into fixed remote gear riser 10 to limit movable claw by thrust pin 6-5 originally
6-3 and the state of clutch plate 6-2 rotary motions are broken, and clutch plate 6-2 is changed into the shape that the free degree is 1 by original zero free degree
State, driving disc spacing pressing 6-1 rotary motion will not be hindered by clutch plate 6-2 and movable claw 6-3, and then can deduce and active
The multi-diameter shaft 1 that disk 6-1 is connected by key also can normally rotate.So under specific direction, multi-diameter shaft 1 can be with moving gear 5
Realize free one-directional rotation.
When opposite direction is moved, because thrust pin 6-5 is simultaneously positioned at clutch plate thrust pin slideway 6-2-9 and remote gear cant board
In blind hole 10-3, limitation clutch plate 6-2 can be played and rotated；While movable claw 6-3 and clutch plate locking groove 6-2-4 one side
Face contact design cause movable claw 6-3 can not counter motion enter, this ensure that thrust pin hemispherical head 6-5-5 cannot be introduced into
Movable claw intersecting via 6-3-4 centre position, but contacted all the time with movable claw main part 6-3-3, it is such to set
Meter causes hemispherical head 6-5-5 can not be withdrawn from from remote gear cant board 10, and thrust pin 6-3 can limit clutch plate 6-2 all the time and movable
Claw 6-3 rotation.Clutch plate 6-2 limited in rotation, the driving disc spacing pressing 6-1 rotations coordinated with clutch plate 6-2 by neck also can be by
To limitation, and then limitation driving disc spacing pressing 6-1 rotation is reached, and then limit turning for the multi-diameter shaft 1 being connected with driving disc spacing pressing by key
It is dynamic, realize the function of backward hold.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
