GEAR WHEEL Russian patent published in 2014 - IPC F16H55/10 F16H55/17 F16H57/04 

FIELD: machine building.

SUBSTANCE: gear wheel includes a body, a toothed rim with teeth and a pair of annular patch pieces fixed on the teeth ends and the wheel body sections adjacent to them. Each tooth is hollow and consists of a pair of plates bent as per the profile of side surfaces of the tooth designed for this wheel, the plates are fixed in end patch pieces and together form the profile corresponding to the designed tooth side surfaces. The plate lagging along the rotation direction, is fitted with L-shaped element with the width equal to the width of the toothed rim. One shelf of L-shaped element is fixed on this plate in near the circle of teeth tops of the rim with forming of the clearance between the element and the second plate, its other shelf faces towards a circle of hollows of rim teeth with formation of the clearance between the element and the second plate. In another plate, on the section of contiguity to the wheel body, along the rim width the viaholes are made.

EFFECT: minimising of costs for manufacture of gear wheels with keeping of their strength characteristics and ensuring of endurance of teeth working surfaces.
