ACCURACY REQUIREMENTS FOR MARINE PROPULSION GEARS WITH SPECIAL REFERENCE TO AVAILABLE MEASURING EQUIPMENT

This paper looks at the need for accuracy in marine propulsion gears in the light of the new ISO standards of 1976 which complement the British Standard BS 1807. Errors linked to speed and to loading are discussed in detail. The Author concludes that present marine gear accuracy standards bear no relation to the requirements of the gear itself. It is to be hoped that the forthcoming revision of BS 1807 will go some way towards rectifying this. Gear measuring equipment now available is adequate to cover requirements in respect of pitch and undulations. Developments in respect of profile measurement of large gears, alignment measurement and surface texture recording in situ would be welcomed. Composite checking could also bear closer examination as a means of demonstrating profile accuracy on large gears. Order from: BSRA as No. 47,334.
