Belt wheel or chain wheel for use in e.g. camshaft adjuster of combustion engine, has flange with lugs arranged at circumference, and mounting holes inserted into flange and lugs in radial direction and at preset angle to each other

摘要

The wheel (1) has mounting holes (8, 9) for detachably connecting the wheel at a drive element or an output element using attachment elements or screw connections, where the wheel is formed as a single piece and made of plastic i.e. thermosetting polymer, composite material or fiber reinforced material. A flange (5) has lugs (6) arranged at a circumference, and forms an abutment surface (10) that is provided at a distance from a running cladding (4). The mounting holes are inserted into the flange and the lugs in a radial direction and at a preset angle to each other.
