Abstract

The gears generate high stresses in the mating positions over the teeth when transmitting the power as
they alter the rotation rate of the machine shaft. The object of this study is to determine the magnitude of
the stresses on a spur gear used in the lathe machine for operations such as boring, facing. The friction
power losses in spur gears can be measured as the integral, multiplied by the friction coefficient and the
elemental slipping, of the normal load along the entire contact line. A full analysis of the effect on
efficiency of the design parameters (number of teeth, gear ratio, pressure angle, addendum shift
coefficient, etc.
