Gas meter counter unit with improved shaft lubrication

摘要

In a meter counter assembly of a gas meter, a rotatable shaft of a gear train is journaled in a bore that extends through a support plate mounted in the housing of the counter. The plate is of a porus material, forming capillary passages for the transmission of lubricant therethroughout. A portion of the support plate extends into a lubricant reservoir in the housing. In use, lubricant migrates through the capillary passages to the bore from the reservoir for lubrication of the shaft.
