Reliability analysis of ball bearing on the crankshaft of piston compressors

Abstract

Technically the system that is the subject of research in this paper is a reciprocating compressor. The goal of the research presented in this paper was to examine the reliability of operation reciprocating compressor with a single cylinder. This study is based on monitoring diagnostic parameters of axial clearance and temperature on tested ball bearings, which are located on the crankshaft of the compressor. The reliability in the work was analyzed observed through monitoring of axial clearance and the temperature of ball bearings and was performed in the laboratory conditions testing. Results of the research on the tested ball bearings show that the size of the axial clearance correspond to the sizes and the temperature before the period of notice that condition and are a good indicator of the reliability of the technical system.
