Discussion on "Recent developments in worm gear manufacture" at the London Section of the Institution

DR. MERRITT expressed his appreciation of the privilege extended to him, as a visitor, of opening the discussion. Not the least part of the value of the paper, in his opinion, lay in the indication which it gave of the detailed attention which was being paid to the question of accuracy. As with all other types of gear, satisfactory performance depends entirely on initial accuracy, and the successful application of worm gearing to high-speed drives, as in the case of turbine drives machinery, and close-ratio gears such as camshaft drives, combined with the high efficiencies now possible, clearly show the advances which have been made in recent years.
