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 a ring groove which is coincident with the ring groove on the bushing. In addition the journal has grooves that extend from the ring groove to be inclined to the direction of rotation of the shaft at an acute angle. The cross-section of the groove smoothly decrease with the distance from the ring groove. 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 заключается в том, что на рабочей поверхности цапфы вала выполнена кольцевая канавка, совпадающая с кольцевой канавкой втулки, при этом от кольцевой канавки цапфы вала выполнены плавно уменьшающиеся по сечению, направленные под острым углом к направлению вращения вала канавки.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 lies in the fact that on the working surface of the shaft pin an annular groove is made, which coincides with the annular groove of the sleeve, while from the annular groove of the shaft pin are smoothly decreasing in section, directed at an acute angle to the direction of rotation of the groove shaft.
