FIELD: machine building.SUBSTANCE: invention can be used to lubricate the high-speed stages of multiple gearing with crankcase lubrication by immersing with the help of auxiliary lubrication pinions. Lubricating device of gearing contains secondary lubricating pinion engaged with above located lubricating gear wheel and immersed in oil bath. Body parts of each lubricating pinion tooth adjacent to the working side surface and both ends of tooth are cut symmetrically relative to circumferential plane of symmetry of the secondary lubricating pinion, with preservation of working side surface part along the whole height of the tooth. Cutouts are planes directed from the line of intersection of the rated working side surface with teeth space circumference perpendicular to the radial plane of symmetry of the tooth, and planes directed from teeth space circumference to their tops perpendicular to tooth end forming a gap along the whole tooth height between these planes and design working side surface of the tooth.EFFECT: higher quality of lubrication.1 cl, 4 dwg |
