ANSI/AGMA 6035-A02 pdf free.Design, Rating and Application of Industrial Globoidal Wormgearing.
The velocity factor table in this standard provides data for sliding velocities up to 6000 feet per minute. For velocities in excess of 6000 feet per minute, the manufacturer should be consulted.
Where the sliding velocity of the worm thread exceeds 2000 feet per minute, additional consideration must be given to the lubrication of gears and bearings. Special lubricants and a pressurized lubrication system may be required.
1.3 Included ratios
The input power formulas for globoidal wormgearing apply for ratios of 3:1 and greater. Engineering practice dictates that ratios in excess of 74:1 should be discussed with the manufacturer.
1.4 ExceptIons
Wildhaber plane enveloping globoidal gearing is not covered in this standard.
This standard does not pertain to globoidal worm- gearing used as speed increasers. For such applications, the manufacturer should be consulted.
1.5 Intended use
The equations and values presented provide a general approach to design and rating. Deviations from the methods and values stated in this manual may be made when justified by experience, testing or more specific analysis. It is intended for use by experienced gear designers capable of selecting reasonable values based on their knowledge of the performance of similar designs and the effect of such items as lubrication, deflection, manufacturing tolerances, metallurgy, residual stresses and system dynamics. It is not intended for use by the engineering public at large.
