Transmission system comprising an oil wet toothed belt

Abstract

A transmission system is provided that has a drive pulley, at least one driven pulley and an oil wet toothed belt. The toothed belt includes a toothing and a back, a first portion, wherein the toothing is coupled to the drive pulley, a second portion wherein the toothing is coupled to at least one driven pulley, a first taut branch which develops towards the driving pulley and a second slack branch which develops towards the driven pulley. The transmission system also includes a fixed containment guide having at least a first wall facing the toothing and/or the back positioned at a distance from the toothed belt between a minimum distance where at rest it is not in contact with the toothed belt and a maximum distance equal to 5% of the length of one between the taut branch and the slack branch.
