Description
Technical field
The utility model is related to engine valve actuating mechanism technical fields, and in particular to a kind of idler wheel with anti-rotation device is endured
Bar.
Background technology
The hydraulic tappet of engine valve clearance adjust automatically is assembled by 3 parts:1. roller bearing, 2. tappet
Ontology, 3. stop pin, 1. roller bearing：Roller bearing is installed in tappet body, and contact cam in surface is compressed by high-pressure oil pump
On cam.2. tappet body：The tappet body cylinder very high for required precision, when the engine runs, tappet body
It moves up and down with the shape of cam.Machine oil is constantly accumulated in operation for it, can increase the energy loss of tappet weight formation.
3. stop pin：Stop pin is arranged on tappet body, to ensure that tappet roller bearing is parallel with camshaft surface.Cam
With the sliding friction of tappet, larger energy loss and accessory loss are caused, influences engine life.
Invention content
It to be endured in order to solve the above technical problems, the purpose of this utility model is to provide a kind of idler wheels with anti-rotation device
Bar by improving the andfrictional conditions of roller lifter and cam, reduces energy loss during engine operating.
To achieve the above object, a kind of roller lifter with anti-rotation device of the utility model, it includes tappet body, institute
It states tappet body and includes integrated setting in the roller groove, two support columns and the lower body for being located at lower end of upper end, two supports
Column is parallel to be located in the middle part of the roller groove and lower body, the roller groove and lower body for hollow design and the roller groove and under
Ontology forms two oilholes with the support column, and roller bearing is equipped in the roller groove, and the roller bearing rolling is connected with
Quad wheel, the lower body side wall is interior to be equipped with an anti-rotation device, and the tappet body is outer convex by anti-rotation device socket one
Wheel shaft, the lower body bottom are equipped with cam, and the cam contact is connected with high-pressure oil pump, a column is equipped in the high-pressure oil pump
Plug holds out against the contact cam.
Further, an axis pin is equipped in the roller groove, the roller bearing rotation is placed on the axis pin.
Further, the anti-rotation device is stop pin.
Compared with prior art, advantage is the utility model：Anti-rotation device ensures tappet roller bearing and cam
Axis surface it is parallel, installed in engine it is corresponding in stop pin guide groove, when being omited in roller lifter movement around Pivot Point Center
There is rotation, the interaction of stop pin and anti-rotation cotter way can promote roller lifter to return with the interaction of cam and roller bearing
Correct position.Even if the angle of a very little, this automatic capturing effect can all occur.Plunger on high-pressure oil pump is pressed on
On cam, energy loss and accessory loss are reduced by the form of rolling, can effectively extend the service life of engine.
