The combination of an endless power transmission belt construction and a pulley therefor, the belt construction and methods of making the same are provided, the belt construction having opposed inner and outer surfaces with each surface defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that are adapted to mesh with a ribbed surface of a pulley, the depth of the grooves of each of the surfaces of the belt construction being substantially less than the approximately 2.4 mm depth of the grooves of the known belt construction that is adapted to have one of the opposed surfaces thereof mesh with the ribbed surface of the pulley, the belt construction also comprising a cushion section and cords with the cushion section being initially disposed on only one side of the cords and the cords thereafter being embedded therein.
In the combination of an endless power transmission belt construction having opposed side edge means and having opposed inner surface means and outer surface means with each said surface means defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves, said belt construction having a certain thickness between the roots of said grooves in said opposed surface means thereof, and a rotatable pulley means having an outer peripheral ribbed surface means meshing with a portion of one of said inner surface means and said outer surface means of said belt construction and defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that respectively have portions thereof for serially meshing respectively with cooperating portions of said grooves and projections of said one surface means of said belt construction, the improvement wherein the depth of said grooves of each said surface means of said belt construction is substantially less than the approximately 2.4 mm depth of the grooves of a similar belt construction that is adapted to have one of the opposed surface means thereof mesh with said ribbed surface means of said pulley means, said belt construction comprising a cushion section and cord means, said cushion section being initially disposed on only one side of said cord means with said cord means thereafter being embedded therein.
In an endless power transmission belt construction having opposed side edge means and having opposed inner surface means and outer surface means with each said surface means defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves, said belt construction having a certain thickness between the roots of said grooves in said opposed surface means thereof, said belt construction being adapted to have one of said inner surface means and said outer surface means thereof mesh with a ribbed outer peripheral surface means or a rotatable pulley means that has said ribbed surface means defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that respectively have portions thereof for serially meshing respectively with cooperating portions of said grooves and projections of said one surface means of said belt construction, the improvement wherein the depth of said grooves of each said surface means of said belt construction is substantially less than the approximately 2.4 mm depth of the grooves of a similar belt construction that is adapted to have one of the opposed surface means thereof mesh with said ribbed surface means of said pulley means, said belt construction comprising a cushion section and cord means, said cushion section being initially disposed on only one side of said cord means with said cord means thereafter being embedded therein.
In a method of making an endless power transmission belt construction having opposed side edge means and having opposed inner surface means and outer surface means with each said surface means defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves, said belt construction having a certain thickness between the roots of said grooves in said opposed surface means thereof, said belt construction being adapted to have one of said inner surface means and said outer surface means thereof mesh with a ribbed outer peripheral surface means of a rotatable pulley means that has said ribbed surface means defining a plurality of longitudinally disposed and alternately spaced apart like projections and grooves that respectively have portions thereof for serially meshing respectively with cooperating portions of said grooves and projections of said one surface means of said belt construction, the improvement comprising the steps of forming the depth of said grooves of each said surface means of said belt construction to be substantially less than the approximately 2.4 mm depth of the grooves of a similar belt construction that is adapted to have one of the opposed surface means thereof mesh with said ribbed surface means of said pulley means, forming said belt construction to comprise a cushion section and cord means, initially disposing said cushion section on only one side of said cord means, and, thereafter, embedding said cord means in said cushion section.
