ADDENDUM MODIFICATION OF CYLINDRICAL SPUR GEARS WITH EQUALIZAED POWERS LOST BY FRICTION BETWEEN THE TEETH FLANKS AT THE POINTS WHERE THE MESHING STARS AND ENDS
Abstract: The paper presents a computation method of the geometrical dimensions for the cylindrical spur gears based on the equalization of the powers lost by friction, between the teeth’s flanks, during the meshing of the teeth. This method, compared to other, computes the addendum modifications considering the friction coefficient. If equalization of the power lost by friction succeeds, at the points where the meshing starts and ends, the specific addendum modification will depend also of the friction coefficient between teeth flanks.
Key words: Power lost by friction, Friction coefficient, Specific addendum modification, Power equalization.
