摘要： A mechanical system, comprising a tappet including a body, a support element defining two bores centered on a first axis, a pin comprising two opposite ends each adapted to be fitted in one of the two bores, and a roller element positioned between the two bores along the first axis and movable in rotation relative to the pin around the first axis. The support element is distinct from the body and fixed thereto, and the support element also comprises at least one antirotation device integrally formed thereto. The mechanical system can be integrated into an injection pump and/or a valve actuator.

摘要： A mechanical system forms a cam follower or a rocker arm and includes a support element, a pin extending between two opposite ends along a first axis and supported by the support element, and a roller mounted on the pin, movable in rotation relative to the pin around the first axis and adapted to roll on a cam. The support element includes a first axial abutment feature blocking the translation of a pin assembly including at least the pin, in a first direction parallel to a second axis perpendicular to the first axis. The mechanical system additionally includes an insert inserted in the support element and supporting the pin opposite the first axial abutment feature, wherein the first axial abutment feature protrudes outside a cavity delimited by the support element and receiving the pin.

摘要： A method for manufacturing a roller, adapted to equip a mechanical system forming a cam follower or a rocker arm. The roller is centered on a central axis and comprising: an outer cylindrical surface adapted to roll on a cam, an inner cylindrical bore adapted to receive a pin belonging to the mechanical system, and two lateral faces extending radially to the central axis. The method includes a machining step forming circular grooves that are concentric with each other on at least one of the lateral faces of the roller. The roller can be installed within a mechanical system.

摘要： A mechanical system comprising: a tappet, including a body; an insert mounted in the body; a pin extending along a first axis; and a roller element movable in rotation relative to the pin around the first axis. The insert supports the pin, while the body supports the insert, along at least one first direction parallel to a second axis which is perpendicular to the first axis. The mechanical system can be integrated into an injection pump and/or a valve actuator.
