This paper describes the experimental characteristics of cantilever type journal bearings in reciprocating compressors for HFC-134a. The purpose of this study is to compare the effects of bearing material, chemically treated shafts, bearing stiffness and refrigerant solubility in the oil to the characteristics of journal bearings lubricated with a mixture ofHFC-134a and lubricating oil As a res...

The influence that recycled low-density polyethylene (LDPE) and lithium thickener concentrations exerts on the thermal and rheological properties of lithium lubricating greases was investigated using different rheological techniques in a temperature range of 25–175◦C. In this way, different lubricating grease formulations were manufactured by modifying the concentration of lithium 12-hydroxyste...

Setting the effect of oil states (sufficient state and deficient state) on temperature field distribution and temperature rise of heavy hydrostatic bearing as the starting point, simulation research is conducted with the FLUENT 6.5, which is popular in current field of scientific research all over the world. The results show that the temperature of heavy hydrostatic bearing has a linearly incre...

induction motor bearing is one of the key parts of the machine and its analysis and interpretation are important for fault detection. in the present work vibration signal has been taken for the classification i.e. bearing is healthy (h) or defective (d). for this purpose, clustering based classification of bearing vibration data has been carried out using principal component analysis (pca) and ...
