Abstract
The invention relates to a belt or chain tensioner (1) for a belt or chain drive of an internal combustion engine, having a base unit (2), an annular tensioning arm (3) which is mounted so as to be rotatable relative to the base unit (2) about an axis of rotation and on which a tensioning roll (4) prepared for pre-tensioning a section of an endless belt or chain is arranged, and two interconnected bearing parts (5, 6), by which the tensioning arm (3) is pivotally mounted on the base unit (2), and the bearing parts (5, 6) are designed as identical parts.
Claims10
A traction mechanism tensioner for a traction mechanism drive of an internal combustion engine, the traction mechanism tensioner comprising a base unit, a ring-shaped tensioning arm supported to be rotatable about a rotational axis relative to the base unit, a tensioning roller provided for pretensioning a section of an endless traction mechanism arranged on the tensioning arm, and two bearing components that abut each other and are connected directly to each other, and by which the tensioning arm is supported for rotation on the base unit, and the bearing components are constructed as identical parts.
A traction mechanism tensioner for a traction mechanism drive of an internal combustion engine, the traction mechanism tensioner comprising a base unit, a ring-shaped tensioning arm supported to be rotatable about a rotational axis relative to the base unit, a tensioning roller provided for pretensioning a section of an endless traction mechanism arranged on the tensioning arm, and two bearing components connected to each other and by which the tensioning arm is supported for rotation on the base unit, and the bearing components are constructed as identical parts, wherein the two bearing components are connected to each other by at least one latch tab connection with a rotationally locked holding of the tensioning arm.
A traction mechanism tensioner for a traction mechanism drive of an internal combustion engine, the traction mechanism tensioner comprising a base unit, a ring-shaped tensioning arm supported to be rotatable about a rotational axis relative to the base unit, a tensioning roller provided for pretensioning a section of an endless traction mechanism arranged on the tensioning arm, and two bearing components connected to each other and by which the tensioning arm is supported for rotation on the base unit, and the bearing components are constructed as identical parts, wherein the bearing components are arranged rotated relative to each other along a periphery with respect to a rotational axis of the tensioning arm.
