摘要:
In a system for coupling a toothed starter ring to a support connected to the output shaft of an internal combustion engine, a complementary substantially cylindrical peripheral surface of the ring is fixed over at least a part of its extent to a substantially cylindrical peripheral surface of the support in such a manner that the ring can deform slightly in the radial direction toward the shaft to reduce the maximum stresses exerted on the ring during a starting operation.

A generally disc-shaped flywheel which is an integral one-piece forged structure formed by forging of a carbon steel blank and consisting of an inner portion having a friction surface and an outer ring gear portion disposed radially outwardly of the inner portion. The flywheel is formed by forging the carbon steel blank to obtain an intermediate product consisting of the inner portion and the outer ring gear portion, hardening the friction surface of the inner portion of the intermediate product, and shot peening the hardened friction surface to form a multiplicity of recesses in the hardened friction surface.

A spur gear camshaft drive for an internal combustion engine having a crankshaft timing gear, a camshaft gear and at least one intermediate gear arranged between the timing gear and camshaft gear is disclosed. At least one of the gears of the camshaft drive is provided with a hub and a gear ring configured in such a way that the gear ring can be turned against the hub up to a predetermined angle. A readjusting element is provided between the hub and gear ring to exert a readjusting force onto the hub and gear ring depending on the torsion exerted.

A coupling device is designed with a flywheel mass which faces a drive and is operatively connected, such that they rotate together, to a driver which acts on the drive. A holder is provided on the flywheel mass, which holder faces the driver and is provided with a tooth system. The driver has an axial attachment, which is likewise designed with a tooth system at its end which faces the holder, in which case at least one tooth of the tooth system is pressed, with radial prestressing, into the tooth gap between in each case two teeth of the tooth system of the holder.

A coupling device having a drive-side centrifugal mass, which is actively connected in rotation-proof fashion to a driving gear that acts on the drive train. On the centrifugal mass, there is an accommodating fixture that faces the driving gear and is equipped with a tooth system. The driving gear has an axial shoulder that, on its end facing the accommodating fixture, is also embodied with a tooth system. At least one tooth of the tooth system of the driving gear is pressed, under radial prestress, into the space between two teeth of the tooth system of the accommodating fixture.

An actuating mechanism installed intermediate the ends of a shaft without access to an end of the shaft is operative to perform a function requiring motion while the shaft is rotating. It includes a split hub mounted on and around the shaft, split ring gears carried by the hub but freely rotatable with resepct thereto, a pinion mounted to be rotated by and to engage the teeth of both ring gears, a drive train operated by the pinion, and preferably electro-magnetic brakes for selectively slowing one of the ring gears with respect to the other without engaging the ring gear, to cause the pinion to rotate.In the embodiments illustrated and described, the pinion is operatively connected to a weight movable with respect to the shaft to permit balancing of the shaft while the shaft is rotating.
