FIELD: machine building.SUBSTANCE: invention can be used in tooth gears lubricated with liquid lubricants by dipping. Gear wheel includes body, gear rim with teeth, width of side surfaces of which on sections of their heads with double-pair engagement, shifted towards tops of teeth by value of axial clearance transmission is equal to half width of side surfaces of legs. Gear wheel also comprises a pair of end of ring pads fixed on teeth ends and parts of ends of body adjacent to toothed rim. Outer diameters of external ends of pads is not less than diameter of circle of vertices of teeth. Outer diameters of inner ends of pads is less than outer diameters of their outer ends.EFFECT: higher quality of lubrication.1 cl, 1 dwg |
