Abstract

1394153 Belt gearing INDUSTRIE PIRELLI SpA 30 Jan 1973 [1 Feb 1972] 4657/73 Heading F2Q In a toothed belt transmission a belt 3 passes around pulleys 1 and 2 and is acted against by a tensioning jockey pulley 4, there being a resilient layer 12 of material on the surface of the belt opposite to that having the teeth, or alternatively on the jockey pulley 4, between the pulley 4 and the reinforcing cords of the belt, to reduce the increase in belt tension due to movement apart of the pulleys 1 and 2. The layer 12 may have longitudinal grooves in it to increase the belt flexibility (Fig. 3, not shown). As shown in Fig. 1 the tensioning of the belt is through pivoting of a plate 5, carrying the jockey pulley 4, about a pivot 6, a bolt 7 holding the plate in position. There may be resilient layers provided both on the belt and on the pulley.
