摘要： In an aspect, a tensioner for tensioning an endless drive member on an engine, is provided, comprising a base that mounts to the engine, a tensioner arm that is pivotally connected to the base for pivotal movement about a tensioner arm axis, a pulley rotatably mounted to the tensioner arm for rotation about a pulley axis that is spaced from the tensioner arm axis, a tensioner spring and a damping member. The tensioner spring is positioned to urge the tensioner arm into an endless drive member. The spring has a first helical end and a second helical end. The first helical end is positioned to transfer force with a first spring end force transfer surface on the base and the second helical end is positioned to transfer force with a second spring end force transfer surface on the tensioner arm. The damping member is positioned in a surrounding relationship with the tensioner spring. The damping member includes a spring force adjustment member having a first end face and a second end face spaced from the first end face by a selected angular spacing. The damping member includes a first portion that contains the spring force adjustment member and that is generally rigid, and at least one second portion that is adjacent the first member and that is flexibly joined to the first member. The spring force adjustment member is positioned between one of the spring ends and one of the spring end force transfer surfaces on one of the base and the tensioner arm. The damping member is frictionally engaged with the other of the base and the tensioner arm during pivotal movement of the tensioner arm relative to the base.

摘要： A chain tensioning device includes a main body, a chain guide and a rotary fluid damper unit. The chain guide is pivotally coupled to the main body to rotate around a rotational axis with respect to the main body. The rotary fluid damper unit is operatively connected between the main body and the chain guide to provide rotational resistance to the chain guide around the rotational axis. The rotary fluid damper unit includes at least one primary flow limiting valve and at least one support member. The primary flexible valve portion of the at least one primary flow limiting valve is configured to flex and contact the at least one support member to form a primary flow path between a free end of the primary flexible valve portion of the at least one primary flow limiting valve and the other of the first and second members.

摘要： The tension roller device provides a support shaft, a securing plate that is fixed on the support shaft, an eccentric hub that is free to rotate relative to the shaft, and a spring that is arranged axially between the eccentric hub and the securing plate. The support shaft includes a stop surface, against which the securing plate is axially supported, and which is delimited radially on the outer side by a circular outer edge. At least one opening is formed in the securing plate, in order to delimit a tongue for radial centering of the spring. The opening is situated radially on the outer side relative to the circular outer edge of the stop surface of the support shaft.
