X2061 X4336 With reference to the attached correspondence in connection with Worm Gears. The merits and disadvantages of the worm gear have been thoroughly discussed by R.{Sir Henry Royce} on several occasions. We do not consider there is the least possible chance of R.{Sir Henry Royce} ever considering a worm axle. There is much less reason for fitting the worm axle since spiral bevels and hypoid bevels were introduced. It is unfortunate they mention the Stutz as an example of a satisfactory worm axle because when we ran the Stutz here on the dynamometer we could not run up to the maximum speed because the axle over-heated and was actually burning off the axle paint. We should be under an obligation if it was agreed to test this axle, therefore we recommend that we should courteously refuse. Hs.{Lord Ernest Hives - Chair} 2 | ||
