Detailed description of the invention
The invention will be further described for embodiment shown in below in conjunction with the accompanying drawings.
Embodiment one: see shown in accompanying drawing 1 and accompanying drawing 2.A kind of for realize power shaft and output shaft in the same direction or counter-rotational bidirectional ratchet 4 mechanism, including axle sleeve 1, upper ratchet 2, lower ratchet 3, there is the ratchet shaft 5 of ratchet 4, commutation slide block 6 and outer housing 7.Wherein, axle sleeve 1 is the power shaft of bidirectional ratchet 4 mechanism, and ratchet shaft 5 is the output shaft of bidirectional ratchet 4 mechanism.
Axle sleeve 1 is sheathed on the outside of part comprising ratchet 4 on ratchet shaft 5, it has fluting, upper ratchet 2 and lower ratchet 3 and is relatively arranged in the fluting on axle sleeve 1 and is positioned at the both sides of ratchet 4.Upper ratchet 2 or lower ratchet 3 include the pawl point near ratchet 4, the pawl tail away from ratchet 4 and the middle part between pawl point and pawl tail respectively, upper ratchet 2 or lower ratchet 3 and axle sleeve 1 contact be partially located in portion.Upper ratchet 2 and lower ratchet 3 are being meshed with ratchet 4 by rightabout, it is assumed that lower ratchet 3 can engage when ratchet 4 rotates clockwise, and upper ratchet 2 can engage when ratchet 4 rotates counterclockwise.
Commutation slide block 6 is slidingly arranged between ratchet 2 and lower ratchet 3 and is against on ratchet 2 and lower ratchet 3.Outside outer housing 7 is sheathed on axle sleeve 1 and make commutation slide block 6 between itself and upper ratchet 2 and lower ratchet 3, axial one end of outer housing 7 is closed by the flange on axle sleeve 1, the other end of outer housing 7 is closed by lock nut 8, ratchet shaft 5 through lock nut 8 by extending to outer housing 7 outside outer housing 7 within.Offering reversing groove on outer housing 7, the local of commutation slide block 6 is exposed by reversing groove.Concrete, commutation slide block 6 be included between outer housing 7 and axle sleeve 1 slide slider bar, be positioned at two inside slider bar and corresponding be respectively butted on ratchet 2 and the shell fragment of lower ratchet 3 mutually, be positioned at outside slider bar and by the operating block exposed in the reversing groove on outer housing 7.The shell fragment of commutation slide block 6 is able to the middle part with upper ratchet 2 or pawl tail, the pawl tail of lower ratchet 3 or middle part and offsets.
Being further fixedly arranged on the backing pin 9 axially positioned ratchet shaft 5 in axle sleeve 1, backing pin 9 is against on the side wheel face of ratchet 4.
The operation principle of this bidirectional ratchet 4 mechanism is:
(1) ratchet shaft 5 dallies counterclockwise with axle sleeve 1 synchronous axial system clockwise and axle sleeve 1:
Operating block on operation commutation slide block 6 makes it to the direction sliding to upper ratchet 2, one shell fragment of commutation slide block 6 is pushed down the pawl tail of ratchet 2 and the pawl point of ratchet 2 is tilted, and the another shell fragment of commutation slide block 6 is pushed down the middle part of lower ratchet 3 and the pawl point of lower ratchet 3 is crushed in the tooth of the ratchet 4 on ratchet shaft 5.When axle sleeve 1 rotates clockwise, lower ratchet 3 is driven to drive ratchet shaft 5 to rotate clockwise；And when axle sleeve 1 rotates counterclockwise, owing to the pawl point of upper ratchet 2 cannot block the tooth of the ratchet 4 on ratchet shaft 5, therefore ratchet shaft 5 is static, axle sleeve 1 dallies counterclockwise.
(2) ratchet shaft 5 dallies clockwise with axle sleeve 1 synchronous axial system counterclockwise and axle sleeve 1:
Operating block on operation commutation slide block 6 makes it to the direction sliding to lower ratchet 3, one shell fragment of commutation slide block 6 is pushed down the pawl tail of lower ratchet 3 and the pawl point of lower ratchet 3 is tilted, and the another shell fragment of commutation slide block 6 is pushed down the middle part of ratchet 2 and the pawl point of ratchet 2 is crushed in the tooth of the ratchet 4 on ratchet shaft 5.When axle sleeve 1 rotates counterclockwise, in driving, ratchet 2 drives ratchet shaft 5 to rotate counterclockwise；And when axle sleeve 1 rotates clockwise, owing to the pawl point of lower ratchet 3 cannot block the tooth of the ratchet 4 on ratchet shaft 5, therefore ratchet shaft 5 is static, axle sleeve 1 dallies clockwise.
(3) ratchet shaft 5 both with axle sleeve 1 synchronous axial system clockwise, also with axle sleeve 1 synchronous axial system counterclockwise:
Commutation slide block 6 is pushed into the centre position of reversing groove, and two shell fragments of commutation slide block 6 push down ratchet 2 and the middle part of lower ratchet 3 respectively so that the pawl point of the sharp and lower ratchet 3 of pawl of upper ratchet 2 is all crushed in the tooth of the ratchet 4 on ratchet shaft 5.When axle sleeve 1 rotates clockwise, drive ratchet shaft 5 to rotate clockwise by lower ratchet 3, when axle sleeve 1 rotates counterclockwise, drive ratchet shaft 5 to rotate counterclockwise by upper ratchet 2.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
