Abstract

Rollenstössel mit einem zylindrischen Führungskörper, der oben zwei Lagerpartien zum Halten einer Achse aufweist, auf der eine Rolle drehbar gelagert ist. Roller tappet with a cylindrical guide body, which has two bearing sections at the top for holding an axle, on which a roller is rotatably mounted.

Zur Gewichtsverminderung sind die Lagerpartien ver­ kürzt und weisen nur zwei nach oben offene Lagermulden auf, in die die Achsenden eingelegt und z.B. durch Verstem­ men befestigt werden. The bearing parts are ver to reduce weight shortens and only have two storage troughs open at the top in which the axle ends are inserted and e.g. by ampl men are attached.

Ferner weist der Führungskörper unter der Rolle einen im Querschnitt rechteckigen Hohlraum auf, in den die Rolle eingreift und der sich bis kurz über den Boden des Führungs­ körpers erstreckt. Furthermore, the guide body has one under the roller in cross-section rectangular cavity in which the role engages and which extends up to just above the bottom of the guide body stretches.
