A cylindrical gear train comprising first and second gears having helical teeth of different thickness with different pitch diameters for the left hand and right hand sides of the teeth and with different nominal angles of inclination and different mesh correction for the mating left hand and right hand flanks of the teeth. Within the normal module range of mn=2-6 mm, corresponding to the normal module range of 2 pi (mm) to 6 pi (mm), and for pitch diameters up to 500 mm, the maximum tooth convergency is 3 DEG and the addendum modification coefficient does not exceed 0.8. |
