摘要： A belt tensioner having a tensioner base and a tensioning arm axially aligned about a pivot shaft defining a pivot axis, the tensioning arm pivotal in relation to the tensioner base about the pivot axis. The tensioner has a bearing positioned around and sealed against the pivot shaft, with the tensioning arm positioned around the bearing. The bearing forms a radial seal between the bearing and the tensioning arm and between the bearing and the pivot shaft. A torsion spring is positioned externally around a portion of the tensioning arm.

摘要： In an aspect, a tensioner is provided for maintaining tension in an endless drive member in a belt-in-oil drive system. The tensioner includes a base that is mountable to a stationary structure and that has a circumferential wall that defines an arm pivot axis, an arm having a radially inner arm surface, and an endless drive member engagement surface that is engageable with an endless drive member, a bushing positioned between the radially inner arm surface and the circumferential wall of the base cup, and a tensioning spring. The arm is supported on the base cup via the bushing. The tensioning spring is positioned to bias the arm in a first direction about the arm pivot axis.

摘要： A pivot joint for a single blade spring tensioner or double blade spring tensioner generates a biased friction loss at a pivot joint. The friction torque generated in one direction of joint rotation is greater than the friction torque generated in the opposite direction of rotation. In one embodiment, the direction of torque bias at the joints is used to make the damping of the blade spring greater in compression than in extension. High damping in compression and low damping in extension is a desirable characteristic for a tensioner in most applications. The device may be designed to act as a one-way clutch or as a two-way clutch. The device may also be designed to apply large friction torques only when the joint undergoes large amplitude motions (loss of control).

摘要翻译：用于单个叶片弹簧张紧器或双叶片弹簧张紧器的枢转接头在枢转接头处产生偏置的摩擦损失。在一个关节旋转方向上产生的摩擦转矩大于在相反旋转方向产生的摩擦转矩。在一个实施例中，接头处的扭矩偏置的方向用于使得叶片弹簧的阻尼在压缩中比在延伸中更大。在大多数应用中，张紧器的拉伸中的高阻尼和延伸中的低阻尼是期望的特征。该装置可以被设计成用作单向离合器或双向离合器。该装置还可以被设计成仅在接头经受大幅度运动（失去控制）时施加大的摩擦转矩。

摘要： A blade tensioner system for a chain that imparts tension to a chain that drivingly connects to a driven shaft to a drive shaft in an engine. The blade tensioner comprises a blade shoe and mating block. The blade shoe has an arcuately curved chain sliding face, a proximal end portion, and a distal end portion having a pair of tapered sides joined by a bottom and at an angle. The mating block has a channel with a pair of tapered sides joined by a bottom and at a second angle for receiving the distal end portion. When load on the chain increases, the tapered sides of the distal end portion and the bottom contact and wedge with the tapered sides of the channel of the mating block, damping chain vibration.

摘要： A tensioner that includes a blade shoe (106), at least one blade spring (112), a ramp 122), and a brake (132). The blade shoe has a curved chain sliding face, an underside, opposite the chain sliding face, a proximal end pivotally attached to ground and a distal end. The ramp is fixed to ground and has a ramp surface (122a) for contacting the chain sliding face or the underside of the blade shoe. The brake is self-energizing, pivotally fixed to ground and has a friction contact surface (132a) for contacting the distal end portion (106c) of the chain sliding face, the blade spring, or the underside of the blade shoe for restricting movement of the distal end of the blade shoe in one direction and allowing movement in the opposite direction.

摘要： A tensioner has a base plate and a pivot arm. A first end of the pivot arm is pivotally mounted to the base plate for rotation about a first axis. A spring biases the pivot arm to rotate in a tensioning direction. A push rod assembly is pivotally mounted to the second end of the pivot arm. The push rod assembly is rotatable about a second axis extending parallel to the first axis. The push rod assembly frictionally engages the pivot arm generating frictional forces counter acting and damping the spring bias. When the tensioning guide is forced to rotate in the tensioning direction, the acting moment arm of the push rod force causing the guide to rotate towards the endless drive, is considerable longer at the end of the tensioning stroke than in the beginning of the stroke.
