Background technology
Roller is one of consumable accessory in injection pump, is strength member wherein.What injection pump was generally used is cylindrical roller, and along with injection pump is continually strengthened, barrel-type roller begins to be used.Because the pump end pressure constantly increases the also corresponding increasing of the contact stress of roller and cam.The increase of stress often causes the aggravation of camshaft and rolling wheel wear, makes fuel feeding anterior angle and each oil supply cylinder angular interval change the diesel engine performance variation.For reducing this contact stress, roller widths continues to increase in the strengthening process of some oil pumps, but simple increase width can only be obtained the part effect, because contact stress can not evenly distribute owing to width increases the back.When roller contacted work with cam, the pressure at two ends maximum was called the edge stress effect.Adopt barrel-type roller, the roller outer surface is cydariform, can make edge stress reduce to more low-level.Facts have proved adopt barrel-type roller can reduce effectively roller and cam this to the contact stress between the friction pair, can prolong the service life of roller and cam like this, have more economic worth than the prolongation roller life-span service life that wherein prolongs cam.
