Schwungrad eines Verbrennungsmotors mit Anlasszahnkranz

摘要

The circumferential region(3) of the flywheel(1) in radial section has a form which corresponds to an enclosed re-entrant right angle which has a circumferential face(10) for attachment of the ring gear(2) on the flywheel and radial face(11) for the contact between the ring gear and flywheel. The inner circumferential face(12) of the ring gear in radial section has a complementary form which corresponds to a projecting right angle and mates with the circumferential face of the flywheel and which has a radial face(14) mating with that of the flywheel. During engine start the ring gear slightly deforms on account of the spacing of the mating faces, and the radial face of the ring gear can slightly slide along the radial face of the flywheel. An Independent claim is included for a flywheel which has a facility for lubricating the radial faces of every tooth on the ring gear.
