Hydrodynamic Lubrication Analysis of a Small Rotary Compressor
소형 회전식 압축기의 동수압적 윤활해석
Abstract
For an analytic investigation on the dynamic behaviour of the eccentric piston and roller in the cylinder of small rotary vane compressors the hydrodynamic lubrication theory is opplied, analogous to the dynamic analysis of a engine bearing. An adequate modification of the equation of journal motion permits stable convergencies of the numeric calculation of the journal orbits. The increase of the outer diameter of the roller and the eccentricity of the piston gives a relative large decrease of the minimum gap between the roller and cylinder.
