FIELD: machine building.SUBSTANCE: invention relates to machine building and can be used in tooth gears. Gear wheel includes body with hub made in form of pair of disks fixed on hub ends and ends of toothed rim, made in form of separate teeth that are not connected to each other, fixed by their ends between disks. Working sections of side surfaces of teeth correspond to design for teeth of this wheel, and non-working sections of these surfaces are made in form of planes, oriented radially relative to wheel. Size of these planes at height of teeth is equal to value of axial clearance of toothed rim. With abutment on base between discs is rigidly fixed ring arranged coaxially relative to wheel axis. Width of ring along its whole circumference is equal to width of toothed rim wheel.EFFECT: higher operational characteristics of gear wheel.1 cl, 3 dwg |
