Abstract
The utility model discloses a wearing-resistant swing-arm for an engine, relating to a gasoline engine and a diesel engine of an automobile and a motorcycle. Preformed wear-resistant circular arc plates (1) with different materials and hardness are fixed on a working surface of an ordinary material rocking arm body (2) by different technological processes. The wearability of the rocking arm is not only effectively raised, but also the arthralgia o fshort long lifetime can be overcome. An optimum rubbing pair is formed for selecting the material and hardness similar to the cam (wobble shaft), and conditions are provided for obtaining the optimal wear-resistant value. The wearing-resistant swing-arm for the engine has the advantages of simple manufacturing process and low cost.
Description
The utility model is a kind of wear-resisting rocking arm that is used for motor.It is applicable to the gasoline and the diesel engine of automobile, motorcycle.
Rocking arm and cam (camshaft) are the major parts of motor.The working surface of the two constitutes a pair of friction and pays by mill.Realize intake and exhaust once, cam just circles, thereby its frequency of okperation height, quick abrasion.Particularly the wearing and tearing of the working surface of rocking arm are even more serious, because the friction working surface girth of cam is more than the octuple of rocking arm friction face length.Past is for improving the wear resistance of rocking arm working surface, generally be steel such as employing 20Cr, by carburizing and quenching, the hardness of working surface is reached more than the HRC55, but its quench-hardened case only have 0.3～0.5mm, worn out soon, make the surface spot occur, and then it is bad that the working surface of cam is also gnawed thereupon, force and change cam and rocking arm, more shake these two not only time-consuming, and economic value is also higher.If the broken foam of metal that grinds off enters in the cylinder with oil, just cause the damage of a series of component, its loss is just bigger.
The existing patent No. 95238262.8 " wear-resisting cam of motorcycle engine and rocking arm " is to adorn a VT5 or VT15 hard alloy blocks respectively on the cam of motorcycle engine and rocking arm working surface.Though it can improve the part wear resistance, pay for friction, still with material with firmly hard grind being wiped of hardness, rocking arm is wearing and tearing earlier still.And be a hard alloy blocks that is difficult for grinding to be fixed on go up grinding machine again after the working surface and form, not only increased grinding man-hour, improved cost, and easily generation surface checking in grinding and the using process.
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of both materials and hardness optional, and fixing means is random, and is simple, and cost is lower, improves the wear-resisting rocking arm of motor in working life again to greatest extent.Pay for forming best friction, try to achieve best wear-resisting value condition is provided.
The purpose of this utility model is achieved in that the wear-resisting rocking arm of a kind of motor, is to give the ceramic or various abrasion resistance alloys of the Tungsten carbite that makes or the metal part that hardens, and adopts technologies such as pressure, weldering, subsides and casting, is fixed on the rocking arm body.
Below in conjunction with wear-resisting arc plate position view, an embodiment of the present utility model is described: on relevant work face position,, mill out the flat-bottom slot of fixing wear-resisting arc plate (1) with the axis hole location through the common material rocking arm of fine finishing (2).Thickness 1mm, material is 38CrMoAe, and via nitride is handled the wear-resisting arc plate (1) of back hardness HV 〉=1000, pastes in the groove with inorganic binder, gets final product with buffing then.
Claims (3)
1. the wear-resisting rocking arm of motor is characterized in that: give the wear-resisting garden arc sheet (1) that makes, be fixed on the working surface position of common material rocking arm body (2);
2. the wear-resisting rocking arm of a kind of motor according to claim 1 is characterized in that wear-resisting garden arc sheet (1) is to select for use various high-abrasive materials to make, such as Tungsten carbite, pottery, various abrasion resistance alloy and the metal part that hardens;
3. the wear-resisting rocking arm of a kind of motor according to claim 1 is characterized in that wear-resisting garden arc sheet (1) is by technologies such as pressure, weldering, subsides and castings, is fixed on the working surface position of rocking arm body (2).
