Abstract

The gear for a gear pump has a uniform radial cross section, having teeth which are fabricated from cylindrical segments. The wheel may comprise a hub block to which teeth are bolted having a right e.g. twelve sided polygonal section with semi-circular grooves along alternate flats, and the teeth having a complimentary half round cross-section. The teeth may be fixed by radial countersunk bolting, and may be mounted with packing plates which modify the radial projections.
