Abstract

The utility model provides a starter for an air-cooled diesel engine. The starter comprises a chassis (1), a primary wound gear shaft (2), a vortex spring gear shaft sleeve (3), a starting shaft (4), a starting handle (5), a one-way locking block (6), a vortex spring (7), an internal side plate (8), a bottom plate (9), a driving plate (10) and a driven plate (11), wherein the vortex spring gear shaft sleeve (3) and the starting shaft (4) are connected with each other in the form of a spline; and the starting shaft (4) can be pushed in the vortex spring gear shaft sleeve (3) in a reciprocating way. According to the utility model, after the diesel engine is started, the diesel engine is separated from the starter.

Description

A kind of air-cooled diesel engine starter

Technical field

The utility model relates to field of agricultural machinery, relates in particular to a kind of air-cooled diesel engine starter.

Background technique

The microtilling machine power motor of peasant's use at present, having a kind of is the Wind-cooling type diesel engine, its Starting mode is a hand pull starting-up.Along with the expansion of the using scope of microtilling machine, the horsepower of this diesel engine is also improving constantly, the hand pull starting-up more and more difficult that becomes, and original boot disk and start rope are easy to damage and break.

In the existing technology, have a kind of rigidity strong, start starter easily, but this starter is behind diesel engine starting; Can be always along with diesel engine to rotate, general diesel engine meeting continuous firing is more than 4 hours, and starter also can be along with rotating more than 4 hours; It is more to generate heat, and is damaged easily.

Summary of the invention

The purpose of the utility model provides a kind of air-cooled diesel engine starter, can realize starting diesel engine after, diesel engine separates with starter.

In order to solve the problems of the technologies described above, the air-cooled diesel engine starter that the utility model provides is achieved in that

A kind of air-cooled diesel engine starter comprises: casing 1, just around gear shaft 2, whirlpool spring gear bush 3, start axle 4, starting handle 5, unidirectional lock dog 6, whirlpool spring 7, side inner panel 8, base plate 9, driving disc 10 and driven disc 11; Said whirlpool spring gear bush 3 is connected with said startup axle 4 spline forms, and said startup axle 4 can promote in said whirlpool spring gear bush 3 back and forth.

Optional, an end is equipped with handball 12 in the outside of casing 1 for said startup axle 4.

The air-cooled diesel engine starter that the utility model provides, whirlpool spring gear bush is connected with a startup axle spline form, starts axle and in the spring gear bush of whirlpool, can promote back and forth; Skewback behind the diesel engine starting on the driven disc promotes driving disc, starts axially outer motion, and driving disc on the starter and the driven disc on the diesel engine are thrown off, and diesel engine is started working, and starter quits work; With respect to starter of diesel engine of the prior art, the starter of the utility model just separates with diesel engine after diesel engine is started working, and does not rotate with diesel engine, and starter can not turn round for a long time, long service life.

Further, the air-cooled diesel engine starter that the utility model provides, one end is equipped with handball in the outside of casing to start axle, the convenient startup axle that promotes.

Description of drawings

Fig. 1 is the air-cooled diesel engine structural representation that the utility model provides.

Embodiment

For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, a kind of air-cooled diesel engine starter comprises: casing 1, just around gear shaft 2, whirlpool spring gear bush 3, start axle 4, starting handle 5, unidirectional lock dog 6, whirlpool spring 7, side inner panel 8, base plate 9, driving disc 10 and driven disc 11; Whirlpool spring gear bush 3 is connected with casing 1 side inner panel 8 through bearing; Just hinged through bearing and casing 1 around gear shaft 2, unidirectional lock dog 6; Whirlpool spring 7 is connected with whirlpool spring gear bush 3 hook forms, and whirlpool spring 7 is connected with casing 1 side inner panel 8 screws, and side inner panel 8 connects with casing 1 electrical pads; Casing 1 is connected with base plate 9 screws, and whirlpool spring gear bush 3 is connected with startup axle 4 spline forms.Start axle 4 and be connected with driving disc 10 electric welding, driven disc 11 is connected with diesel engine flywheel screw, and base plate 9 is connected with the diesel engine fan guard.Starting axle 4 can promote in whirlpool spring gear bush 3 back and forth.

As shown in Figure 1, an end is equipped with handball 12 in the outside of casing 1 to start axle 4.

During use, pass through just around gear shaft 2 with crank, 3 pairs of whirlpool springs of whirlpool spring gear bush 7 carry out energy storage; Simultaneously unidirectional lock dog 6 pins whirlpool spring gear bush 3 automatically stores whirlpool spring 7 abilities, after energy storage is full, promotes to start the handball 12 of axle 4 outer ends; Make to start driving disc 10 introversive movements and driven disc 11 interlockings that axle 4 reaches and the startup axle welds together, in the time of can not engaging, rotate first around gear shaft 2; Promote to start the handball 12 on the axle 4 simultaneously; Driving disc 10 is engaged with driven disc 11, depress the diesel engine decompression handle behind the joint, throttle is put to enable position.Move starting handle 5, unidirectional lock dog 6 is rotated, auto-lock function is opened; Energy discharges, and starter whirlpool spring 7 releases energy and drives 3 rotations of whirlpool spring gear bush, and whirlpool spring gear bush 3 drives startup axle 4 driving discs 10 and rotates; Driving disc 10 drives driven disc 11 through oblique abaculus and rotates, and driven disc 11 drives the diesel engine flywheel and rotates diesel engine starting work; Skewback behind the diesel engine starting on the driven disc 11 promotes driving disc 10; Start outwards motion of axle 4, driven disc 11 is thrown off with driving disc 10 each other, starts end-of-job.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
