20130225346 | DRIVE BELT FOR TRANSMITTING A DRIVE MOVEMENT, AND METHOD FOR PRODUCING A DRIVE BELT - A drive belt having a belt body which is made of a flexible material and a tensile reinforcement that extends in belt axial direction and which is surrounded by said belt body in sections at least to improve the tensile strength of the body in belt longitudinal direction wherein the tensile reinforcement is a carbon cord made of a plurality of twisted carbon fibers with a plurality of cavities between the fibers which are charged with a filler material in part at least. A first portion of the carbon fiber cavities is charged with a rupture risk reducing filler of a type different from the belt body flexible material and a second portion of said cavities of the carbon fibers is filled with belt body flexible material. The carbon cord has less than 0.2 mg of belt body flexible material per one millimeter | 08-29-2013 |
20130237358 | ELEVATOR BELT ASSEMBLY WITH NOISE AND VIBRATION REDUCING GROOVELESS JACKET ARRANGEMENT - An elevator load bearing assembly includes a plurality of cords within a jacket. The cords are spaced from an exterior surface on the jacket such that the spacing remains generally constant along the length of the belt. The jacket has a smooth, uninterrupted exterior surface for contacting sheaves as the belt moves in the elevator system. A method of making the inventive belt assembly is disclosed. The inventive belt assembly minimizes the possibility for generating an annoying, audible sound and vibration during elevator operation. | 09-12-2013 |
