FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanical engineering. Spur gear has the shape of a cylinder obtained by rotating it around the axis, as well as a hub with a keyway and a rim with teeth made on it. The teeth relative to the generatrix are made in the form of a part of a circle, the radius of which is determined by the ratio 
, where B is the value of the chord, equal to the width of the rim of the gear rim of the wheel, H is the height of the chord, equal to the greatest convexity of the teeth in the middle of the rim of the gear.
EFFECT: increased accuracy of spur gear teeth manufacturing.
