Abstract
A composite gear part for a gear arrangement includes a shaft part adapted to be rotationally mounted in the gear arrangement, an inner part made from a first material, and an outer part made from a second material. The outer part is fixed circumferentially to the inner part, and the outer part has a plurality of gear teeth formed therein. The outer part must be made from a material which is sufficiently durable and hard to fulfill requirements for gear teeth, but the material of the inner part need not fulfill such requirements. The inner part includes recesses or apertures arranged so that the inner part supports the outer part in an asymmetric manner.
