A method of producing a movable tensioning element of a tensioning device for tensioning flexible drive means, in particular for timing chain drives of internal combustion engines, the tensioning element having at least a tensioning piston and a tensioning rail made of a plastic material, with the tensioning rail being arranged on a tensioning end of the tensioning piston. A correspondingly implemented tensioning element as well as to a tensioning device including such a tensioning element is provided. The method of producing the movable tensioning element includes placing the tensioning piston into an injection mold suitable for producing the tensioning rail; injecting the plastic material into the injection mold; encompassing the tensioning piston by the plastic material in certain areas thereof; and letting the plastic material solidify under formation of a positive connection between the tensioning piston and the tensioning rail.

A link chain is provided, in particular a drive chain of a combustion engine, with chain links connected one to another by a chain articulation. The inner and outer chain links, which preferably are arranged in alternation, each have at least two link plates arranged in parallel with each other, each with two link openings. One link pin in each case extends through one of the link openings of the link plates to form a chain articulation. In this design, the link plates are made of a boron-manganese steel.

A toothed chain includes inner chain links and outer chain links alternatingly succeeding one another, the outer chain links comprising at least two outer plates, at least one middle plate and two pins. The inner chain links include at least two inner plates formed as tooth plates, the at least one middle plate being positioned between the inner plates. Each of the inner plates has a plate thickness d and a land width b, a ratio of plate thickness d to land width b being greater than 1.6.

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.
