Description
Technical field
The present invention relates to diesel engine starting technical field, especially a kind of shock-resistant air-cooled diesel engine starting dog dish.
Background technique
Along with the development of agricultural economy, Agricultural Mechanization Degree progressively improves, agricultural cultivating & machine is more and more universal, its power source is diesel engine, diesel engine is that burning diesel oil is to obtain exergonic motor, it is large that it has power, the thermal efficiency is high, the advantages such as economic performance is good, diesel engine can must make it enter operating condition by a set of starting mechanism before work, existing starter of diesel engine has employing hand starting and electricity to start two kinds, although electricity start mode is convenient, but complex structure, and it is also inconvenient in maintenance, and adopt traditional hand starting pattern, namely the starting dog of starter can snap onto in diesel engine pawl dish, and then realize hand-operated starter drive diesel engine starting, but find in actual applications, easily there is rigid impact in the starting dog on starter and the starting dog dish contacting point on diesel engine flywheel, namely even there is slight crack in the easy distortion in the place of contacting with each other, and also easily there is fracture due to this rigid impact in the bearing pin supporting pawl, therefore, in practice, often need maintenance because this problem result in starter and change component, working life is not long, and this problem annoyings people always, a kind of i.e. simple but also protecting against shock method of Be very effective is not also found to solve this problem.
Summary of the invention
The technical problem to be solved in the present invention is: the flimsy problem of starting dog dish caused in order to the starting dog and the rigid impact of starting dog dish that overcome starter in prior art, provides a kind of shock-resistant air-cooled diesel engine starting dog dish.
The technical solution adopted for the present invention to solve the technical problems 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 to the annular portion of the large end in bowl portion, described pawl coil buckle is connected to annular 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 and starting dog head top surface are plane contact.The side face of traditional starting dog dish has multiple hole, this some holes is used to contact with starting dog, be not difficult to know, after starting dog throws away, starting dog stretches in hole, due to be at a high speed get rid of into, therefore the sidepiece of starting dog and hole have very large shock, all can bring huge injury to starting dog and starting dog dish, the present invention changes traditional structure, change pawl groove structure into, the same rotation direction that is distributed as of pawl groove distributes, the rotation direction of pawl groove is the direction thrown away with starting dog is consistent, when entering 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, namely face contacts with the complete of face, therefore, the effect that such design brings is exactly be no longer go to drive starting dog dish with the sidepiece of starting dog, but directly adopt the head top surface of starting dog as stress surface, its ability to bear will improve greatly, shock-resistant ability improves thereupon.
If because pawl coil and starter panel consider cast inblock in technique, be limited to its structure cannot cast, therefore split type method is adopted, pawl coil buckle is connected to starter panel inwall, can have with under type, first kind of way, described annular portion inwall has the first groove that at least one is outwards recessed, described first groove, for being uniformly distributed in annular portion inwall, described pawl coil outer wall has first projection corresponding with the first groove, and described first projection coordinates with the first groove setting-in.
The second way, described annular portion inwall has at least one protruding to second of convex, described second projection, for being uniformly distributed in annular portion inwall, described pawl coil outer wall has corresponding second groove protruding with second, and described second projection coordinates with the second groove setting-in.
The mode that buckle connects is not limited to two kinds of above-mentioned citing, and the connection of every snap is all in protection scope of the present invention.
Further, the conical surface in described bowl portion has multiple equally distributed through hole, and the bottom surface in bowl portion has axis hole.
The invention has the beneficial effects as follows, the present invention, by changing the structure of starting dog dish, improves the shock-resistant ability of starting dog dish, the working life of starting dog dish is added, provides cost savings.
