    • The invention proposes a mechanical roller tappet (1a, 1b) comprising a tappet housing (2a, 2b) shaped out of sheet metal, a drive roller (3) actuable by a cam (9) and an axle (5a, 5b) on which the drive roller (3) is mounted, end portions (24) of the axle (5a, 5b) being supported in axle eyes (23) of the tappet housing (2a, 2b), said tappet housing (2a, 2b) comprising a tappet skirt (10a, 10b) and a tappet bottom (16) possessing a contact surface (21) for an adjacent engine component on a power take-off side. At an end of the tappet skirt facing the cam, the tappet bottom is connected to the tappet skirt and is shaped into the interior of the tappet skirt while forming a pocket for receiving the drive roller, the axle eyes being arranged in first sections (18) of the tappet bottom while being spaced from an inner peripheral surface (19) of the tappet skirt and extending substantially parallel to the longitudinal direction of the tappet skirt, the contact surface being arranged on a second section (20) of the tappet bottom connecting the first sections to each other.
    • 本发明提出了一种机械辊挺杆(1a,1b),其包括由金属板形成的挺杆壳体(2a,2b),由凸轮(9)和轴(5a,5b)致动的驱动辊(3) 安装驱动辊(3),轴(5a,5b)的端部(24)被支撑在挺杆壳体(2a,2b)的轴眼(23)中,所述挺杆壳体(2a,2b)包括 挺杆裙部(10a,10b)和挺杆底部(16),其具有用于在动力输出侧的相邻发动机部件的接触表面(21)。 在挺杆裙部朝向凸轮的端部,挺杆底部连接到挺杆裙部,并形成在挺杆裙部的内部,同时形成用于接收驱动辊的凹口,轴眼布置在第一部分(18 ),其与所述挺杆裙部的内周表面(19)间隔开并且基本上平行于所述挺杆裙部的纵向方向延伸,所述接触表面布置在所述挺杆底部连接的第二部分(20)上, 第一部分彼此。
