Abstract
285,492. Aktiebolaget Ljungstr÷ms Angturbin. Feb. 18, 1927, [Convention date]. Toothed wheels.-At. least one of a pair of helical toothed wheels 1, 2 has the tooth spaces 7 considerably deeper than usual and the thickness of the teeth 6 at the pitch circle considerably less than the width of the tooth spaces. The active parts of the teeth may be thicker than the sub-roots, though necessarily thinner than the teeth 5 shown. The teeth of the wheel 2 may be similar to the teeth 6, or of normal profile 11 but of greater thickness than normal as shown at 9. In modifications, the teeth of the wheel 2 may be normal in all respects, in which case there will be play between the engaging teeth, or may be similar to the active parts of the teeth 6 but without deepened spaces. Spaces of exceptional depth may be made between groups of two or more teeth. Where one wheel only, preferably .the smaller, is provided with the deepened and widened spaces, it is made axially broader than the other wheel. In such construction, however, only the sub-roots of the teeth need be extended beyond the breadth of the other wheel. The spaces are preferably produced by milling, and part of such operation may be performed by an end-mill.
