FIELD: machine building.SUBSTANCE: tooth-wheel consists of a body in the form of a disk with a hub and of a toothed rim with teeth. Disk outside diameter is equal to diameter of tips of the toothed rim, the toothed rim is made in form of a profile ring with width equal to teeth width. Outside profile of the ring corresponds to profile of the toothed rim, designed for the given wheel. The ring by one its end face is secured on the disk end face, at the second end face of the ring a plat ring is secured, its outside and internal diameters are equal to the appropriate diameters of the profile ring.EFFECT: optimised design of the tooth-wheel, lower costs of its manufacturing.2 dwg |
