Although we are now able to produce good axles, we must still continue in our efforts until we are absolutely satisfied that we can obtain consistently bevels practically equal to a worm drive in silence. To do this it is important that we know exactly why the fours pitch axle is better than the fives pitch. I propose that in order to do this we must continue our experiments on the fives pitch and try and make them like the fours pitch. The following is a summary of the suggestions (some of which I have already made) to accomplish this end. - 1. Continue the addendum of pinion. 2. Increase the curvature. As regards interference, I do not think it is possible to overdo it and in all tests at least full Reinecker allowances should be made. Weight of axles should be some function of their strength. An old type axle should be tested for weight and X/40 | ||
