Bearing Capacity and Temperature Rise Characteristics Analysis of Herringbone Groove Hydrodynamic Lubricating Bearing

摘要

In this paper, numerical analysis of the high speed and small herringbone groove hydrodynamic lubricating bearing's bearing capacity, rotational speed effected on the bearing's eccentricity ratio and temperature rise, film thickness, oil film pressure distribution was solving by Reynolds equation under the Reynolds boundary condition, temperature rise was solving by Reynolds equation. The results shown that the temperature of bearing decreased first, then increased with eccentricity increasing, eccentricity ratio increased with bearing's load increasing but decreased with journal's rotational speed increasing, compared to normal sliding bearing, herringbone groove hydrodynamic lubricating bearings had higher stability and bearing capacity.
