FIELD: mechanical engineering. ^ SUBSTANCE: gear transmission comprises, at least, one driving and one driven gearing members which are in permanent engagement with each other and rotate in a given direction. The profile of teeth surface of the gearing members, which do not rotate in a given direction, has hollow with contact area and auxiliary area adjacent to it. The profile line of the surface of the contact area of the driving and driven gearing members which lies in the plane perpendicular to the axis of rotation is inclined to the radial direction of the driving gearing member at an angle of 90o ± 15o when the teeth of the gearing members are in engagement with these areas. ^ EFFECT: enhanced reliability. ^ 2 cl, 2 dwg
