Abstract

784,430. Toothed gearing. PHILLAC SOC. ANON. March 24, 1955 [March 1, 1955], No. 8622/55. Class 80 (1). In reversible gears of the kind having helicoidal teeth and parallel axes in which the inclinations of the teeth of the pinion and of the gear-wheel are different whilst the axial pitches are the same, and in which the tooth contact is displaced from the plane of the axes of the gears, the profiles of the teeth of the pinion 3, 4 and gear-wheel 5, 6 are completely outside and spaced with respect to one of the " rolling circles " 1 of the gears and in. side and spaced with respect to the other 2. These " rolling circles " are the pitch circles of a pair of conventional gears of equivalent ratio about the same axes.
