Abstract

1,137,035. Toothed gearing. SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU G.m.b.H. 31 Jan., 1967 [29 July, 1966], No. 4625/67. Heading F2Q. [Also in Division B3] A worm for the transmission of motion is formed, by a non-cutting process such as rolling, with a thread whose root diameter increases with a flat or curved taper 5 until it equals the outer diameter 1 of the worm. The root 6 of the thread is of curved form.
