説明
In order to drive a worm by a worm wheel, we must use a multithreaded worm with large lead angle. But such worm gears are very difficult to be made. Since David Brown and Son's Co. in England has been successfully making these gears, I examined a pair of worm and Worm wheel made by the Company. As a result I have found the following essential points : a) The lead angle of the worm is about 45°, that seems to be taken to work at the maximum efficiency. b) A special care has also been taken to lead in lubricating oil to the point of mesh of tooth surfaces even under heavy load. c) Top relief and root relief have been given on the worm tooth. d) Crowning of about 0.025mm has been given on the worm thread, too. e) The worm wheel has been made of phosphor bronze and the worm of hardened steel (Hs=74), its surface being ground to mirror finish.
