Publication number: 20150133250Abstract: A belt having a tensile cord embedded in the belt, extending in a longitudinal direction and made up of two components: a tensile component and a sacrificed component. The sacrificed component may be broken into a plurality of discontinuous segments. The tensile component provides most of the reinforcement of the belt. The sacrificial component of the precursor cord protects the tensile component from excessive stretching during cord treating and winding, but breaks, melts, or yields during mandrel expansion during the belt molding process, thus preserving the stretchability of the tensile component.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Applicant: The Gates CorporationInventors: Shawn Xiang Wu, Charlie Ochoa, Lance Hall, Tae Hee Cheong

Publication number: 20140287862Abstract: The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.Type: ApplicationFiled: February 1, 2012Publication date: September 25, 2014Applicant: The Gates CorporationInventors: Mitsuhiro Yamada, Keiji Sakamoto, Shinji Uchigashima
