Abstract
The utility model relates to a starting jaw of an impact-resistant air-cooled diesel engine. The starting jaw comprises a starting board and a jaw ring, wherein the starting board comprises a frustum-shaped bowl part and an annular part which is connected with the large end of the bowl part; the jaw ring is buckled with the inner wall of the annular part; a plurality of jaw grooves with same rotation direction are uniformly distributed on the inner wall of the jaw ring; each jaw groove is formed by connecting an arc surface with a groove bottom surface in a smooth transition manner; and the groove bottom surfaces and the top surface of the head part of the starting jaw are in surface-to-surface contact with each other. The structure of the starting jaw is changed, so that the starting jaw has an impact-resistant capability, the service life of the starting jaw is prolonged, and the cost is saved.
Description
Technical field
The utility model relates to the diesel engine starting technical field, especially a kind of shock-resistant air-cooled diesel engine starting dog dish.
Background technique
Development along with agricultural economy, the farm mechanization degree progressively improves, agricultural cultivated machine is more and more universal, its power source is diesel engine, diesel engine is that burning diesel oil obtains exergonic motor, it is big that it has power, thermal efficiency height, advantages such as economic performance is good, diesel engine must can make it enter operating condition by a cover starting mechanism before work, existing diesel engine starting device has the hand starting of employing and electricity to start two kinds, though the electricity start mode is convenient, but complex structure, and also inconvenience aspect maintenance, and adopt traditional hand starting pattern, the starting dog that is starter can snap onto in the diesel engine pawl dish, and then realize that hand-operated starter drives diesel engine starting, but find in actual applications, rigid impact appears in starting dog dish contacting point on the starting dog on the starter and the diesel engine flywheel easily, the i.e. place's of being in contact with one another easy deformation even slight crack occurs, and support the bearing pin of starting dog because fracture also appears in this rigid impact easily, therefore, in practice, because this problem has caused starter often need overhaul and change component, working life is not long, and this problem is perplexing people always, also do not find a kind of namely simply again obvious results protecting against shock method solve this problem.
The model utility content
The technical problems to be solved in the utility model is: the flimsy problem of starting dog dish for the starting dog that overcomes starter in the prior art and the rigid impact of starting dog dish cause provides a kind of shock-resistant air-cooled diesel engine starting dog dish.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of shock-resistant air-cooled diesel engine starting dog dish, comprise starter panel and pawl coil, described starter panel comprises the bowl portion of taper type and is connected in the annulus portion of bowl big end of portion, described pawl coil buckle is connected in annulus portion inwall, described pawl coil inwall has multiple tracks with the uniform pawl groove of rotation direction, described pawl groove is formed by connecting by arc surface and groove bottom rounding off, and described groove bottom contacts for the face face with the starting dog head top surface.Have a plurality of holes on the side face of traditional starting dog dish, these holes are used for contacting with starting dog, be not difficult to know, after starting dog throws away, starting dog stretches in the hole, since be at a high speed get rid of into, therefore sidepiece and the hole of starting dog have very big bump, be all can bring huge injury to starting dog and starting dog dish, the utility model changes traditional structure, changes pawl groove structure into, and being distributed as with rotation direction of pawl groove distributes, the direction that the rotation direction of pawl groove is with starting dog throws away is consistent, when entering the pawl groove after starting dog throws away, arc surface can play the buffer function to starting dog, and the end face of groove bottom and starting dog just in time can be fitted, be that face contacts with the complete of face, therefore, the effect brought of design is exactly no longer to be that sidepiece with starting dog removes to drive the starting dog dish like this, but the head top surface that directly adopts starting dog is as stress surface, its ability to bear will improve greatly, and shock-resistant ability improves thereupon.
Because if pawl coil and starter panel are considered cast inblock on technology, being limited to its structure can't cast, therefore adopt split type method, pawl coil buckle is connected in the starter panel inwall, and following mode can be arranged, first kind of mode, have at least one outwards first recessed groove on the described annulus portion inwall, described first groove has first projection corresponding with first groove for being uniformly distributed in annulus portion inwall on the described pawl coil outer wall, and described first projection cooperates with the first groove setting-in.
The second way, has at least one to second projection of convex on the described annulus portion inwall, described second projection has second groove corresponding with second projection for being uniformly distributed in annulus portion inwall on the described pawl coil outer wall, described second projection cooperates with the second groove setting-in.
The buckle ways of connecting is not limited to above-mentioned two kinds of giving an example, and the connection of every buckle mode is all at protection domain of the present utility model.
Further, have a plurality of equally distributed through holes on the conical surface of described bowl portion, the bottom surface of bowl portion has axis hole.
The beneficial effects of the utility model are that the utility model has improved the shock-resistant ability of starting dog dish by changing the structure of starting dog dish, makes increase the working life of starting dog dish, provides cost savings.
