Definitions
- the invention relates to a Umschiingungstrieb, in particular control drive for an internal combustion engine or one of its ancillaries with at least one driving gear and at least one abreibendem gear and a tensioning or deflection roller and with a connecting belt (toothed belt or chain drive), at least one the gears (compensating gear) is designed so that it imparts a non-uniformity in the rotation of the drive with the aim of calming the instinct.
- Control drives of internal combustion engines with a crankshaft drive wheel, at least one camshaft driven gear and a chain or toothed belt or other aggregate drives present on internal combustion engines are subject to vibration changes due to torque fluctuations or changes in angular velocity which lead to audible noises in resonance ranges can. This is associated with increased frictional forces that can affect the life of the belt drive and its efficiency.
- At least one of the wheels should be designed such that it imparts nonuniformity to the drive during rotation, this being achieved in DE 195 20 508 A1 in that either a driving wheel or an aborting wheel the wheel is out of round and / or mounted eccentrically.
- a driving wheel or an aborting wheel the wheel is out of round and / or mounted eccentrically.
- the non-round or eccentrically mounted wheel must be operated in a defined frequency and phase position in order to superimpose the given non-uniformity of the belt drive and thus cause a resonance shift.
- the invention is therefore the object of a belt drive of the type mentioned in such a way that the arrival and aborted wheels do not need to be rotationally positioned.
- the compensating gear is a tensioning or deflecting roller provided with a profile toothing securing a phase-constant running with the belt drive for the wrapping means.
- the tensioning pulley or idler pulley be provided with a toothing for the belting means in order to obtain the necessary phase constant for the differential gear, which is suitable for normal tensioning. and pulleys yes not required, there is the advantage that the attached and abraded wheels, so especially the Kurbelwellen ⁇ wheel and the camshaft, do not need to be rotationally positioned so that the device and the initial balance of the belt drive simplifies designed.
- the clamping or deflection roller formed as a pulley with molded ball bearing can be provided either with a non-circular pitch circle of the tooth profile and / or an eccentric pulley outlet.
- FIG. 1 is a perspective view of a tensioner according to the invention
- Fig. 2 is an enlarged longitudinal section through the tension roller of FIG. 1 and
- Fig. 3 is an enlarged end view of the tension roller.
- the tensioning roller 1 shown is designed as a pulley with a ball bearing 3, which is encapsulated by a plastic gear 4.
- the design is made such that the center axis 5 of the plastic gear 4 is offset relative to the axis of rotation 6 of the ball bearing 3, so that an eccentric pulley discharge results.
- the pulley shown has a circular pitch circle in an off-center run, whereby force fluctuations by periodically recurring sweeping bias variations of the pulley with an external profile toothing 2 wrap around toothed belt can be achieved.
- the invention is not limited to the illustrated embodiment.
- a non-circular pitch of the tooth profile may be provided such that it is for example oval, resulting in an arrangement that is particularly suitable for four-cylinder engines for sedation.
- polygonal shapes can be realized corresponding non-round pulleys for other cylinder numbers of the internal combustion engine.
- the pulley could also be made of sintered metal. reference numerals
