Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
Referring to shown in Fig. 1 to Fig. 5, in the present embodiment, a kind of arrangement of clutch for motor-operating mechanism includes clutch
Device gear 1, ratchet 2, pull-fork assembly, clutch shaft 3 and manual shaft 4, described clutch gear 1, ratchet 2 and pull-fork assembly assembling
On described clutch shaft 3, described pull-fork assembly includes shift fork gear 5 and two shift forks 6, the described manual shaft being structure as a whole
Being provided with the manual actuation gear 7 being meshed with described shift fork gear 5 on 4, described shift fork gear 5 is arranged at said two shift fork
The side of 5, described shift fork gear 5 is assemblied on described clutch shaft 3 rotationally by bearing 8, and the side of described bearing 8 leads to
Cross shaft block ring and carry out spacing.
Described ratchet 2 is arranged in described clutch gear 1, and it includes that ratchet body 20, described ratchet body 20 pass through
Centre bore 21 uses keyway to be fixed on described clutch shaft 3, and the side of described ratchet body 20 is limited by shaft block ring
Position, and the outer rim of described ratchet body 20 is symmetrically arranged with two secter pats 22, the ratchet of said two secter pat 22 both sides this
Body 20 outer rim all offers wedge surface 23, and described wedge surface 23, the sidewall of secter pat 22 form wedge with the inwall of described clutch gear 1
Groove 24, described wedge groove 24 has four altogether, lays respectively at the both sides of two secter pats 22, is movably disposed in described wedge groove 24
There is needle roller 9, and described needle roller 9 is limited by described wedge groove 24 and cannot roll out wedge groove 24, described needle roller 9 and described secter pat 22
Being provided with spring 10 between sidewall, said two shift fork 6 inserts between described ratchet body 20 and clutch gear 1, and is positioned at
Between two wedge grooves 24 of homonymy, described clutch gear 1 is meshed with driven gear 11, described driven gear 11 and motor shaft
Gear 12 is meshed.
Described ratchet body 20 is circular configuration, and said two shift fork 6 is the circle coordinating described ratchet body 20 to arrange
Arc plate.
The side of described clutch gear 1 is fixed with baffle plate 13 by fixing screw 12, and the center of described baffle plate 13 is opened
Being provided with endoporus, be provided with copper sheathing 14 between described endoporus and described clutch shaft 3, shaft block ring is passed through in the outside of described copper sheathing 14
Carry out spacing.
Time electronic, generator shaft gear 12 drives driven gear 11, driven gear 11 drive clutch gear 1 to rotate, as
When really clutch gear 1 turns clockwise, the two of which needle roller 9 in four needle rollers 9 is just stuck in wedge groove 24, and spring 10 pushes up
Live needle roller 9；If clutch gear 1 rotates counterclockwise, two other two needle rollers 9 are just stuck in wedge groove 24, spring 10
Withstand needle roller 9, in now needle roller 9 is stuck in wedge groove 24 and with the contact internal walls of clutch gear 1, so pass through frictional force clutch
Gear 1 just rotates with ratchet 2, and ratchet 2 and drive clutch shaft 3 rotate, thus lead agency running.
When motor is failure to actuate, starting moving axis 4 by wrench, manual shaft 4 manually drives gear 7 to drive shift fork gear
5 rotate, and shift fork gear 5 is inserted in the middle of ratchet 2 and clutch gear 1, if shift fork 6 rotates clockwise, shift fork 6 withstands on symmetry
On two needle rollers 9, stress spring compression, now needle roller 9 does not contacts with the inwall of clutch gear 1, ratchet 2 and clutch gear
1 separates, and such shift fork gear 5 just can easily drive ratchet 2 to operate, and ratchet 2 and drive clutch shaft 3 rotate, thus drive
Organisation operations；If shift fork 6 rotates counterclockwise, shift fork 6 withstands on the needle roller 9 of two other symmetry, stress spring compression, now
Needle roller 9 does not contacts with the inwall of clutch gear 1, and ratchet 2 and clutch gear 1 separate, and such shift fork gear 5 just can be light
Driving ratchet 2 to operate, ratchet 2 and drive clutch shaft 3 rotate, thus lead agency running.
Above example simply elaborates ultimate principle and the characteristic of the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and change both fall within
In scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
