Abstract
A gear train in a counter unit of a rotary positive displacement gas meter includes loosely fitting tubular sleeves telescoped around rotatable shafts in the train. The sleeves are located between gears that are partially immersed in a lubricant reservoir contained within the counter unit and adjacent bearings and gears that are out of direct contact with the lubricant in the reservoir. During operation of the meter, oil from the reservoir flows through passages formed between the inside of each sleeve and the outside of the shaft upon which the sleeve is mounted so that the gears and the bearings in the counter unit are lubricated.
