ROLLER TAPPET DEVICE AND METHOD FOR PRODUCING A ROLLER TAPPET DEVICE

摘要

The invention relates to a roller tappet device (1) for a pump, comprising a tappet (3) with a longitudinal axis (L), a tappet housing (5) with an inner lateral surface (26), a bearing shell (7) with an outer lateral surface (16), and a roller (9) with a rotational axis (D). The bearing shell (7) has a bearing shell recess (19) in which the roller (9) is rotatably mounted, and the bearing shell (7) has a pin (11) on a face facing away from the bearing shell recess (19), said pin being received in a housing bearing (21) of the tappet housing (5). The bearing shell (7) is coupled to the tappet housing (5) in a fixed manner via an outer lateral surface (12) of the pin (11) and an inner lateral surface (22) of the housing bearing (21), and the roller (9) is supported on a drive device of the pump and is designed to transmit a force from the drive device to the tappet (3) via the bearing shell (7) along the longitudinal axis (L) during the operation of the pump.
