Abstract

FIELD: mechanical engineering. SUBSTANCE: bearing comprises shaft journal and bushing provided with antifriction layer and ring groove. The working surface of the journal is provided with preferably odd number of flats, no less than three, the width of which is less than the width of the bushing. Smooth bevels are provided at the ends of the flat in the direction of rotation of the shaft. EFFECT: enhanced reliability. 2 dwg

Изобретение позволяет повысить надежность и экономичность подшипника за счет упрощения конструкции, уменьшения радиальных габаритов, уменьшения расхода масла и потребляемой мощности. Гидродинамический подшипник скольжения содержит цапфу вала и втулку с антифрикционным слоем и кольцевой канавкой. Новизна изобретения заключается в том, что на рабочей поверхности цапфы вала выполнена преимущественно нечетное количество лысок, не меньше трех, ширина которых меньше ширины втулки, а на концах лысок по направлению вращения вала выполнены плавные скосы.The invention improves the reliability and economy of the bearing by simplifying the design, reducing radial dimensions, reducing oil consumption and power consumption. The hydrodynamic sliding bearing comprises a shaft journal and a sleeve with an antifriction layer and an annular groove. The novelty of the invention lies in the fact that on the working surface of the shaft journal, a predominantly odd number of flats is made, no less than three, the width of which is less than the sleeve width, and smooth bevels are made at the ends of the flats in the direction of rotation of the shaft.
