Abstract
A power transmission belt having a belt body with an inside surface and an outside surface, with the belt body having a compression section and a tension section, spaced outside of the compression section. At least a first part of the tension section is defined by a chlorosulfonated polyethylene rubber composition having a chlorine content of 15 to 30% by weight. At least a second part of the compression section is defined by a rubber composition that is different than the rubber composition of the first part.
Claims36
A power transmission belt comprising:
- a belt body having an inside surface and an outside surface,
- said belt body having a compression section and a tension section spaced outside of said compression section,
- at least a first part of said tension section being defined by a chlorosulfonated polyethylene rubber composition having a chlorine content of 15 to 30% by weight, and
- at least a second part of said compression section being defined by a rubber composition that is different than the rubber composition of said first part.
A power transmission belt comprising:
- a belt body having an inside surface and an outside surface,
- said belt body having a compression section and a tension section spaced outside of said compression section,
- at least a first part of said tension section being defined by a chlorosulfonated polyethylene rubber composition having a chlorine content of 15 to 30% by weight, and
- at least a second part of said compression section being defined by a rubber composition that is different than the rubber composition of said first part,
- said rubber composition defining the second part being at least one of a) chlorosulfonated polyethylene rubber composition having a chlorine content of 15 to 30% by weight, b) a hydrogenated nitrile rubber composition, c) a nitrile rubber composition, and d) a chloroprene rubber composition, and
- wherein a magnesium, oxide-aluminum oxide solid solution is added to the chlorosulfonated polyethylene in at least one of the first and second parts.
A power transmission belt comprising:
- a belt body having an inside surface and an outside surface,
- said belt body having a compression section and a tension section spaced outside of said compression section,
- at least a first part of said tension section being defined by a first rubber composition,
- at least a second part of said compression section being defined by a rubber composition that is different than the first rubber composition,
- said rubber composition defining the second part being at least one of a) chlorosulfonated polyethylene rubber composition having a chlorine content of 32 to 45% by weight, b) a hydrogenated nitrile rubber composition, c) a nitrile rubber composition, and d) a chloroprene rubber composition.
A power transmission belt comprising:
- a belt body having a length, an inside surface, an outside surface, and a plurality of teeth on the inside surface and spaced lengthwise of the belt,
- there being a canvas layer on the teeth,
- said belt having a compression section and a tension section spaced outside of said compression section,
- at least a first part of said tension section being defined by a chlorosulfonated polyethylene rubber composition having a chlorine content of 15 to 30% by weight, and
- at least a second part of said compression section being defined by a rubber composition that is at least one of a) a chlorosulfonated polyethylene rubber composition having a chlorine content of 32 to 45% by weight, b) a hydrogenated nitrile rubber composition, c) a nitrile rubber composition, and d) a chloroprene rubber composition.
