POWER TRANSMISSION BELT

摘要

The invention provides a power transmission belt which is superior in oil resistance so that it is swollen to only a reduced degree, reduced in hardness, and small in abrasion if the rubber layers are stained with oil while the belt is being used in an oil-present environment. Such a power transmission belt has rubber layers which comprise a compression rubber layer and an adhesion rubber layer both of which are vulcanized and bonded to each other and load carrying cords are embedded in the adhesion rubber layer, wherein at least the compression rubber layer between the two rubber layers is formed of vulcanizate obtained by vulcanizing ethylene-±-olefin-diene rubber with an organic peroxide and a trifunctional co-crosslinking agent.
