Abstract

FIELD: mechanical engineering. SUBSTANCE: hydrodynamic axial support comprises thrust bearing with smooth working surface and pivot mounted on the shaft. The end face surface of the pivot is provided with spiral grooves inclined to the direction of rotation of the shaft at an acute angle. The grooves are converging from the center of the pivot to its periphery and smoothly connected with the ring groove on the end face of the pivot. EFFECT: enhanced reliability. 2 dwg

Изобретение позволяет повысить несущую способность опоры и снизить ее массу и габариты. Гидродинамическая осевая опора содержит подпятник с гладкой рабочей поверхностью и смонтированную на валу пяту, торцевая поверхность которой выполнена со спиральными канавками, направленными под острым углом к направлению вращения вала. Новизна заключается в том, что канавки выполнены сужающимися от центра пяты к ее периферии и плавно соединены с кольцевой канавкой на торцевой поверхности пяты.The invention improves the bearing capacity of the support and reduce its weight and dimensions. The hydrodynamic axial support comprises a thrust bearing with a smooth working surface and a heel mounted on the shaft, the end surface of which is made with spiral grooves directed at an acute angle to the direction of rotation of the shaft. The novelty lies in the fact that the grooves are made tapering from the center of the heel to its periphery and are smoothly connected to the annular groove on the end surface of the heel.
