Abstract

1312164 Toothed belt gearing INDUSTRIE PIRELLI SpA 19 July 1971 [6 Aug 1970] 33739/71 Heading F2Q To ensure long service life and reduce wear of the flanks of the belt teeth of an endless positive driving belt 3 in which the belt teeth 4 have substantially straight inclined flanks radiused both at their tips and at their roots by an arc 16 of a circle, the belt teeth are proportioned such that the radius of said arc 16 is equal to a value which falls within the range from 5 to 10% of the pitch p of the belt teeth 4, the ratio between the whole depth h of the belt teeth 4 and their pitch p and the ratio between the dimension s of the belt teeth 4 along their tip line and their pitch p falling within the range from 0À25 to 0À4 and being preferably within the range from 0À3 to 0À38, and the ratio between the whole depth h of the belt teeth 4 and the diameter d 1 of the smaller pulley 1 with whose teeth 5 the teeth 4 of the belt 3 are to mesh falling within the range from 0À05 to 0À20.
