Abstract
A power-storage starting apparatus for the diesel engine includes a big gear, a small gear, an overdrive clutch, a ratchet, a spring and an engine base. The big gear is rested on the diesel engine crankshaft via the overdrive clutch. The central end of the spring is fixed on the big gear and the other end is fixed on the engine base. On the engine base is disposed the small gear meshed with the big gear, and on which the ratchet is fixed side by side. The pawls set on the corresponding position to the ratchet are connected with the starting knob.
Description
Technical field
The present invention relates to internal-combustion engine, particularly to the improvement of diesel engine starting device.
Background technique
Small-sized single cylinder diesel engine has a wide range of applications in the agricultural machinery field, and its starting drive has hand mode and electric Starting mode.Hand mode is to rotate the bent axle of diesel engine with shaking the hand, and makes it to start; The electricity Starting mode is to install starting electrical machinery on diesel engine, and starting electrical machinery rotates by the flywheel of gear driven diesel engine during work, makes it to start.Because the cylinder compresses power of diesel engine is big, effort when hand, and easily bounce-back, dangerous; Electric starter cost height is unsuitable for extensive popularization.
Summary of the invention
The diesel engine starting device that the object of the invention is to provide a kind of laborsaving, safety, simple in structure and low in cost uses with convenient.
The solution of the present invention is: a kind of energy-storing starter for diesel engine, comprise big small gear, free wheel device, ratchet, clockwork spring, support, gearwheel is enclosed within on the bent axle of diesel engine by free wheel device, the center-side of clockwork spring is fixed on the gearwheel, the other end is fixed on the support, also is provided with the small gear that meshes with gearwheel on the support, fixes and show ratchet on the small gear, be provided with ratchet in the corresponding position of ratchet, ratchet is connected with the startup knob.
Be shaped on small gear or the ratchet and shake the hole.
Advantage of the present invention is: by shaking the hole rotation pinion, drive gearwheel and rotate during use, make clockwork spring screw energy storage, and by the ratchet locking, loosen ratchet during startup, the elastic force of clockwork spring drives crankshaft of diesel engine and rotates, and starts diesel engine.Owing to drive gearwheel clockwork spring is screwed by small gear, laborsaving during rotation, also have the advantage of safety, simple in structure and low in cost in addition.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a cross-sectional view.
Mark among the figure: 1 diesel engine, 2 gearwheels, 3 clockwork spring position limit cycles, 4 clockwork springs, 5 free wheel devicees, 6 crankshaft of diesel engine, 7 small gears, 8 ratchets, 9 start knob, 10 torsion springs, 11 ratchets, 12 shake the hole, 13 keys, 14 supports, 15 bearings.51 outer rings in free wheel device wherein, 52 needle rollers, 53 inner rings.
Embodiment
In conjunction with Fig. 1 and Fig. 2, embodiment's energy-storing starter for diesel engine, comprise gearwheel 2 and small gear 7, free wheel device 5, ratchet 8, clockwork spring 4, support 14, gearwheel 2 is enclosed within on the bent axle 6 of diesel engine by free wheel device 5, fixedly connected with gearwheel 2 in the outer ring 51 that is free wheel device 5, inner ring 53 is fixedlyed connected with crankshaft of diesel engine 6 by key 13.
The center-side of clockwork spring 4 is fixed on the gearwheel 2, and the other end is fixed on the support 14.
Also be provided with the small gear 7 with gearwheel 2 engagement on the support 14, fixing and show ratchet 8 on the small gear 7, be provided with ratchet 11 in ratchet 8 corresponding positions, ratchet 11 is connected with startup knob 9.
Among the embodiment, small gear 7 arranged side by side and ratchet 8 be ratchet 8 in the outside, the center of ratchet 8 is shaped on shakes hole 12, its shape and existing diesel to shake the hole identical, shake the hand during use and insert wherein, in order to drive small gear 7 and ratchet 8 rotates.
The rotating shaft of ratchet 11 is provided with torsion spring 10.
During use, shake the hand to insert and shake in the hole 12, rotate towards clockwise direction shown in Figure 1, drive small gear 7 and ratchet 8 rotations, small gear 7 drives gearwheels 2 and rotates, and clockwork spring is screwed.Ratchet 11 prevents from ratchet 8 lockings from falling back.At this moment, because free wheel device 5 is in sliding mode, crankshaft of diesel engine 6 can not driven.
During startup, pull and start knob 9, ratchet 11 breaks away from ratchet 8, it is free to rotate that ratchet 8 is removed locking, gearwheel 2 rotates under the elastic force effect of clockwork spring 4 toward the clockwise direction, this moment since the needle roller 52 of free wheel device 5 with outer ring 51, inner ring 53 jam-packeds, free wheel device 5 is in jointing state, gearwheel 2 drives crankshaft of diesel engine 6 and rotates, and diesel engine is activated.Clockwork spring 4 is limited in wherein by clockwork spring position limit cycle 3, prevents to dissipate.
Owing to drive gearwheel 2 by small gear 7 clockwork spring 4 is screwed, it is laborsaving when rotating to shake the hand, and just screw clockwork spring 4 this moment, rebound phenomena in the past can not occur, safe.In addition, compare, also have the advantage of simple in structure and low in cost with electric starter.
