Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Internal-combustion engine Manual starting device as shown in Figure 1, 2, 3, comprising: outer cover 1, is formed for holding the space of the parts of this starting drive in this outer cover 1.
In described outer cover 1, be provided with bearing support block 9, described startup axle 2 is supported on respectively on described outer cover 1 and bearing support block 9 inner sides by the bearing 11 at two ends.
Start the outside that engaging mechanism 8 is assemblied on described startup axle 2 and is positioned at bearing support block 9, this starts engaging mechanism 8 for starting the torque output of axle.
On described startup axle 2, be provided with wind spring fixed plate 10, hold the both sides that power wind spring 3 and reset wind spring 4-1 lay respectively at described wind spring fixed plate 10.
Holding power wind spring 3 is sleeved on described startup axle 2, and be contained in 9 of described wind spring fixed plate 10 and bearing support blocks, the inner of the described power of holding wind spring 3 is fixing with startup axle 2, outer end and wind spring fixed plate 10 are fixing, hold power wind spring 3 for storing the torque of stay cord reel, and when drive plate 5 is released, stored torque is delivered on startup engaging mechanism through starting axle.
Stay cord reel 4 is supported on described startup axle 2 rotationally, and stay cord 4-2 is wrapped in the grooving in the periphery of stay cord reel, is provided with stay cord handle 4-4 in the outer end of stay cord.One side end face of stay cord reel is provided with annular groove, reset wind spring 4-1 is contained between the annular groove and wind spring fixed plate of described stay cord reel, the inner of reset wind spring 4-1 and stay cord reel 4 are fixing, outer end and described wind spring fixed plate 10 are fixing, this reset wind spring 4-1 can make described stay cord reel 4 revolutions, with the described stay cord 4-2 that unrolls.
Referring to Fig. 5, drive plate 5 is assemblied on described startup axle 2 by spline, and this drive plate is provided with raceway boss 5-1, and the periphery of drive plate is provided with gear teeth 5-2.
Referring to Fig. 4, one-way clutch seat 6 is sleeved on the raceway boss 5-1 of described drive plate 5, at described one-way clutch seat, along axis, offers three mounting hole 6-1, with screw, by described mounting hole, described one-way clutch seat 6 is fixedly connected with the end face of stay cord reel 4.On described one-way clutch seat, be provided with three grooves, make to form three slot rolling 6-2 between the outer circumferential face of three grooves of described one-way clutch seat and the raceway boss of drive plate, in each slot rolling, be provided with roller 6-3 and the elastic component that acts on roller, form one-way clutch structure, described elastic component consists of the stage clip 6-5 that pushes up a 6-4 and be located in the cylinder of top, and top cylinder 6-4 pushes up and is pressed on roller 6-3 under stage clip 6-5 effect.
Locking release component 7 is installed in rotation on outer cover 1 and is provided with return spring 7-3, one end of locking release component be provided with one with described drive plate on the detent projection 7-1 of gear teeth 5-2 engagement, and the self-locking arm 7-2 coordinating with described outer cover 1 outer wall, at the other end of locking release component, be provided with the handle 7-4 of convenient operation.Described locking release component can only be towards a side turn-off, and its rotation to opposite side is by the conflict institute locking of described self-locking arm and outer cover, with keep or discharge described in hold the coiled state of power wind spring.
When drive plate 5 rotates with the opposite direction (being also the forward direction of stay cord reel 4) of internal combustion engine start direction, as arrow institute distance pole direction in Fig. 3, the detent projection 7-1 of described locking release component 7 is driven by the gear teeth 5-2 of drive plate, thereby drive locking release component to turn an angle to the right, allow drive plate 5 with the counter-rotation of internal combustion engine start direction.When drive plate stops the rotation of this direction, locking release component 7 under the effect of return spring 7-3, is turned back to lock position again.When described locking release component 7 is during in lock position, because the rotation to the left of locking release component is limited by the conflict of self-locking arm and outer cover, therefore make the rotation with internal combustion engine start direction of drive plate 5 locked by this locking release component, only have when operator are by locking release component to the right after turn-off, the drive plate that obtains discharging could freely rotate with internal combustion engine start direction.
Said apparatus in use, operator pull out stay cord handle 4-4, by stay cord 4-2, drive stay cord reel 4 forwards, now described stay cord reel 4 drives one-way clutch seat 6 to rotate, again by the effect of roller and elastic component, drive described drive plate 5 to rotate, thereby the startup axle 2 of drive and its spline fitted is with the counter-rotation of internal combustion engine start direction, holds 3 coilings of power wind spring described in making.When operator unclamp stay cord handle 4-4, stay cord reel 4 turns round under the effect of reset wind spring 4-1, stay cord 4-2 is regained, due to the one-way clutch principle of one-way clutch seat 6 with drive plate 5, now rotating stay cord reel 4 is separated with drive plate 5, and the drive plate 5 starting on axle 2 keeps motionless under the locking of locking release component 7, thereby keep holding the coiled state of power wind spring 3.In like manner, operator repeatedly pull stay cord 4-2 again, and further pretension holds power wind spring, to increase, holds the stored rotating force of power wind spring.When holding power wind spring 3 coiling enough tightly time, operator just pull the handle 7-4 of locking release component 7, make its rotating opening, the locking of disengagement to drive plate 5, make to start axle 2 and holding under the driving of power wind spring 3, with internal combustion engine start direction quick rotation, the startup pawl 8-1 in described startup engaging mechanism 8 stretches out under the effect of centrifugal force, thereby be combined with I. C. engine crankshaft, reach the object of starting apparatus combustion engine.
