  • Electrically conductive timing belt
    Patent number: 6770004
    Abstract: An electrically conductive article (1) which maintains the conductive property over an extended use life is comprised of an electrically conductive thermoplastic layer (8) on the surface which is in contact with another article. When forming belts for synchronous drive systems, in addition to maintaining the electrical properties, the conductive layer exhibits high abrasion resistance and good tooth formation. A bonding layer (9) may be provided between the article body and the conductive layer (8).

  • Power transmission drive system
    Patent number: 6672983
    Abstract: A drive system comprising a driver pulley, a driven pulley (22), and a belt (10). The belt (10) has a pulley engaging surface (16) comprised of a plurality of transversely extending self-tracking teeth (18). The driven pulley (22) has a non-grooved, crownless belt engaging surface (24). The material (20) forming the pulley engaging surface (16) of the belt (10) having a relatively low coefficient of friction, and the material (28) forming the belt engaging surface (24) of the driven pulley (22) having a relatively high coefficient of friction.
