CYLINDRICAL TOOTHED WHEEL FOR A HELICOIDAL GEAR AND A MOLD FOR OBTAINING A CYLINDRICAL TOOTHED WHEEL OF THIS TYPE.

摘要

Cylindrical cogwheel for a helical gear, with a first wheel disk (12), which carries on a cylindrical surface or in the form of a truncated cone teeth, and at least a second wheel disk, which carries a shaped front surface of a truncated cone teeth, the two wheel discs (13, 14) being limited on a boundary surface, at least one of the two front surfaces inclined in the direction of the boundary surface (15) radially inwards convergently, and that each tooth of the first wheel disc and a tooth assigned to that of the second wheel tooth are permanently pierced with each other on the boundary surface (15), characterized in that the cylindrical cogwheel is formed as a cylindrical cogwheel of rigid synthetic material of a piece .
