The utility model provides a rocker arm. The first swing end of the rocker arm is provided with an adjustment screw mounting hole for installing the valve clearance adjustment screw. The rocker arm is provided with a main oil passage connecting the adjustment screw mounting hole, and the side wall of the adjustment screw mounting hole and an oil storage tank connected with the main oil passage. The first swing end of the rocker arm is equipped with a valve clearance adjustment screw, which is installed in the adjustment screw installation hole. The valve clearance is adjusted by adjusting the axial position of the valve clearance adjustment screw in the adjustment screw installation hole. By setting an oil storage groove connected with the main oil passage in the adjustment screw installation hole, the oil outlet of the main oil passage along the axis of the adjustment screw installation hole can be enlarged so as to make the oil outlet of the main oil passage wider along the axis of the adjustment screw installation hole. After the displacement between the annular oil tank and the main oil channel occurs, oil can still be supplied to the annular oil tank through the oil storage tank, so that the valve adjustment screw can supply oil smoothly, and solve the problem that the adjustment screw can not supply oil smoothly due to the adjustment of valve clearance. The utility model also provides a diesel engine.

摇臂及柴油发动机
本技术涉及柴油机
,更具体地说,涉及一种摇臂及柴油发动机。
技术介绍
摇臂是将推杆运动转变为气门运动的零件。发动机在运转过程中,摇臂内部油道有机油通过,机油流动方向有两种:一种是机油经机体上的主油道,依次经过挺柱、推杆(凹头)、气门间隙调整螺钉、摇臂油孔,然后到达摇臂与摇臂轴摩擦副;一种是机油经机体、缸盖、摇臂座、摇臂油孔、气门间隙调整螺钉内部油孔、垫块,然后到垫块与气门桥摩擦副。垫块与气门桥摩擦副是柴油机中最为重要的摩擦副之一,一旦润滑不良,该摩擦副的异常磨损可能会造成气门升程失控,甚至气门无法打开,柴油机无法运行等严重故障。气门间隙调整螺钉上有环形油槽,当环形油槽与摇臂孔对中时,机油才能顺利到达垫块与气门桥摩擦副之间,起到润滑作用。然而由于气门或座圈磨损等问题,会导致气门间隙变小,重新调整气门间隙调整螺钉后,尤其是多次调整后,很容易导致环形油槽和摇臂孔不对中,从而使得调整螺钉供油不畅,导致垫块与气门桥摩擦副产生润滑不良问题。因此,如何解决由于气门间隙调整造成调整螺钉供油不畅的问题,是目前本领域技术人员亟待解决的问题。
技术实现思路
