AUTOMATIC BELT TENSIONER FOR ENGINE

摘要

The present disclosure provides an automatic belt tensioner for an engine which automatically adjusts the tension of a belt for transmitting rotational force between an engine and an auxiliary machinery component. The automatic belt tensioner includes: a tensioner body mounted at the engine side and having an internal space; a tension spring installed in the internal space of the tensioner body; first and second damping shoes coupled by the tension spring; a first arm having a hinge portion coupled to the first damping shoe; a second arm having a hinge portion coupled to the second damping shoe; and idlers rotatably mounted on the first and second arms, respectively, and also supporting the belt. The first hinge portion which is a rotation center of the first arm and the second hinge portion which is a rotation center of the second arm are rotatably coupled to the tensioner body.

主权项

1. An automatic belt tensioner for an engine, which automatically adjusts tension of a belt for transmitting rotational force between an engine and an auxiliary machinery component, the automatic belt tensioner comprising:
a tensioner body which is mounted on a side of the engine and has an internal space; a tension spring which is in the form of a coil spring and installed in the internal space of the tensioner body; a first damping shoe and a second damping shoe which are coupled to a first end and second end of the tension spring, respectively; a first arm which has a first hinge portion that is formed at a first end of the first arm and coupled to the first damping shoe; a second arm which has a second hinge portion that is formed at first end of the second arm and coupled to the second damping shoe; and idlers rotatably mounted on the first arm and the second arm, respectively, and supporting the belt, wherein the first hinge portion which is a rotation center of the first arm and the second hinge portion which is a rotation center of the second arm are rotatably coupled to the tensioner body in a state in which the first hinge portion and the second hinge portion are concentrically disposed.
