摘要： Disclosed is a tensioner for use in an engine. The tensioner comprises a fixed structure that fixes to the engine. A movable structure is mounted for movement relative to the fixed structure in a belt tensioning and opposite directions. A pulley member has a belt engaging surface that engages with the belt. One of the fixed and movable structures has an interior surface defining a fluid chamber containing fluid and the other includes a chamber dividing structure. The chamber dividing structure defines first and second chamber portions on opposing sides thereof. A biasing element biases the movable structure in the tensioning direction to tension the belt. Relative movement of the movable structure in the tensioning direction displaces fluid from the first to the second chamber portion and increases fluid pressure in the first chamber portion and decreases fluid pressure in the second chamber portion, and the reverse occurs during movement of the movable structure in the opposite direction. The chamber dividing structure allows the fluid to flow between the chamber portions in a restricted manner so as to yieldingly resist the relative movement of the movable structure and thereby dampen such movement. The chamber dividing structure is constructed such that the fluid flow restriction is greater when the movable structure moves in the opposite direction than in the tensioning direction, thereby providing the movable structure with greater resistance to movement in the opposite direction than in the tensioning direction.

摘要： A belt tensioner for a motor vehicle engine comprises a pivot shaft and an eccentric pivoted structure mounted for pivoted movement on the pivot shaft. The belt tensioner has a rotatable pulley member mounted for rotation on the eccentric pivoted structure. A spring is constructed and arranged to bias the eccentric pivoted structure in a direction tending to force the rotatable pulley member into tensioning engagement with a belt trained about the pulley member. A mounting bolt is constructed and arranged to mount the belt tensioner on the motor vehicle engine, said pivot shaft being movable relative to said mounting bolt and towards said belt during a belt tensioner installation procedure. A linear guiding structure provides surfaces of interengagement between said belt tensioner and said motor vehicle engine to limit movement of the pivot shaft to linear movement toward the belt during the installation procedure. The present invention also relates to a method of installing a belt tensioner in which the pivot shaft moves in a substantially exactly linear fashion as the tensioner is moved into tensioning engagement with the belt. In a preferred embodiment, when the belt tensioner is moved into tensioning engagement with the belt, an external force is applied to the tensioner to balance any belt load forces tending to tilt the tensioner during installation. The present invention also discloses a tensioner that has contact portions that oppose the tilting force applied by the belt during installation, and a portion that extends beyond the contact portions to facilitate installation.

摘要： A tensioner includes a plunger slidably inserted in a housing and biased by spring means. The spring means include sequentially operable first and second portions in which the first portion has a relatively larger pitch and large spring modulus and the second portion has a relatively small pitch and small spring modulus. When the spring means is depressed a certain degree, the coils of the second spring portion 16 will move into close contact with each other to vary the spring modulus. Thus, the amount of backward movement and jutting out speed of the plunger will be decreased, thereby a required tensile force will be given to a belt, or the like, without delay.

A tension adjusting spring is coupled to an eccentrically pivotable pulley support member. A damper for damping the pivoting speed of the support member is provided between the support member and the fixed member. The fixed member is provided with a cam surface abutting a piston of the damper. The cam surface is tapered downwards in a direction in which the support member pivots in a direction to increase the belt tension.

摘要： An auto-tensioner has a fixed portion fixed portion fixed to a base, a displaceable device displaceable with respect to the fixed portion and contacting a belt, a tensioning device for urging the displaceable device so as to impart a tension to the belt while absorbing a portion of any fluctuation in the tension, and a vibration absorbing device disposed between the fixed portion and the displaceable device and capable of absorbing a portion of the fluctuation in the tension. The vibration absorption device includes a multi-disk fluid viscosity vibration damper having a least one fixed disk member fixed in relation to the fixed portion, at least one displaceable disk member displaceable together with the displaceable device, and a fluid which produces a viscosity resistance against the displacement of the displaceable disk member with respect to the fixed disk member.
