Abstract

PURPOSE: To facilitate the manufacture and to improve the durability and the wear- resistance of a pump by fitting sleeves made of a chromium carbide alloy to the journals of a shaft and using wear-resistant ceramic bearings.
CONSTITUTION: Sleeves 12 and 13 made of a non-ionization tendency, such as a chromium carbide system alloy (CrC+Ni), are fitted to the journals of a shaft 11. Wear-resistant ceramic bearings 14 and 15 are fitted corresponding to the sleeves 12 and 13' respectively. Thus the durability of the sliding surface is improved. Further, the cost of the shaft 11 is reduced as the shaft itself can be made of steel and the journal parts are reinforced by the chromium carbide system alloy sleeves 12 and 13.
