摘要： A rocker joint for a bush chain or roller chain, comprises a bush having a through-passage running along the bush longitudinal axis, a first rocker surface formed in the through-passage, and a pin arranged in the through-passage of the bush and which has a second rocker surface formed thereon. A chain comprises inner and outer chain links, which are offset relative to each other, the inner and outer chain links being connected by rocker joints, each of which comprises a bush and a pin. A friction-reducing joint and a chain with reduced friction and less wear are provided, and thus a reduced CO2 emission of the associated internal combustion engine, the chain being stable and easy to produce. This is achieved in that the bush is configured as a straight circular cylinder in which the through-passage is arranged in the bush eccentrically with respect to the longitudinal axis of the bush.

A mounting plane defined by the mounting surface of the fastening flange intersects the tensioner housing at an axial distance from the guiding surface of the guide shoe at most 40% of axial transport length of the tensioner between the guiding surface of the guide shoe and the tensioning surface of the tensioning shoe. The camshaft bearing bridge has a contact surface for the fastening flange, to be in contact with the mounting surface of the fastening flange. A camshaft-camshaft chain drive for an internal combustion engine comprising such a tensioner is provided, where the camshaft bearing bridge can be attached to an engine block component.

摘要： The present invention relates to a traction drive with a compensating device for vibration reduction of a driven shaft, for example a camshaft, a water pump shaft or an injection pump shaft of an internal combustion engine, having a drive wheel which is coupled to the shaft, having a drive means, and having at least one compensating mass which is relatively movable in the traction drive and having at least one actuating mechanism for moving the compensating mass. Here, the compensating mass is movable in or counter to the rotational direction of the shaft, and the actuating mechanism is formed as a tangentially acting actuator for moving the compensating mass. The invention also relates to a method for vibration reduction in a traction drive, having a driven shaft, a drive wheel and a drive means, wherein at least one actuating mechanism moves at least one compensating mass which is relatively movable in the traction drive, having the steps: activating the actuating mechanism, moving the compensating mass and generating a compensating torque at the driven shaft. In the case of a control drive with a camshaft adjusting system for the angular adjustment of the control time, the camshaft which is movable relative to the traction drive can simultaneously be used as a compensating mass for vibration reduction.
