摘要:
A belt and method of marking a belt. A layer (30) of polyethylene material is joined or cured to a belt (100). The layer is optically distinguishable from a belt body (10). The layer is etched to expose a portion of the belt body in order to contrast the layer with the belt body. A second layer (40) of polyethylene material may be applied adjacent to the first layer. The second layer is optically distinguishable from the first layer. The first or second layer is etched using cutting, grinding or laser light in order to expose portions of the adjacent layer, or of the belt body, thus providing a method of permanently marking the belt.
摘要:
La courroie est formée essentiellement en un matériau polymère et possède des dents arrondies supérieures et inférieures qui s'étendent le long des surfaces supérieure et inférieure respectivement de la courroie. La courroie comprend une section de tension (29) sous la surface supérieure (30), une section de compression (30) sous la surface inférieure (32), et une section portante (33) disposée entre la section de tension et la section de compression. Le rapport entre le pas des dents inférieures et supérieures (45 à 44) de la courroie (28) est d'environ 1,40, et le rapport entre la hauteur des dents inférieures et supérieures (47 à 46) est d'environ 1,77, alors que le rapport entre l'épaisseur (42) de la courroie et son épaisseur de flexion (43) est d'environ 3,98.

An improvement in a multiple band continuously variable transmission that provides equal speed ratios for each band (5) throughout a range of overall transmission speed ratios through the use of radially contoured pulley sheaves (4).
摘要:
A transmission belt, for use particularly in laundry washers, laundry dryers and laundry washer-dryer combinations, for transmitting rotation between the motor and the drum of a machine of this type. The belt is of the elastically expansible type in the form of an endless loop, and provided with a plurality of reinforcing strands (8) embedded in the material of the belt, each strand being composed of a plurality of synthetic textile fibres, preferably polyamide fibres, which are not prestretched and stranded together with at least 300 turns for each longitudinal meter of the textile fibres. This belt is elastically expansible to a degree permitting it to adapt itself to the driving and driven pulleys of the machine to thereby ensure effective and constant tensioning of the belt.

摘要:
The belt construction is formed mainly of polymeric material, and has rounded top and bottom teeth respectively extending along the length of the top and bottom surfaces of the belt construction, the belt construction comprising a tension section (29) having the top surface (30), a compression section (31) having the bottom surface (32), and a load-carrying section (33) disposed intermediate the tension section and the compression section. The bottom to top tooth pitch ratio (45 to 44) of the belt construction (28) is approximately 1.40, and the bottom to top tooth depth ratio (47 to 46) thereof is approximately 1.77, while the belt thickness (42) to flex thickness (43) ratio thereof is approximately 3.98.

摘要:
The present invention relates to a friction-transmission belt, which has a friction-transmission surface of which at least a part is able to come into contact with a pulley, and which is provided with a compressed rubber layer formed of a product obtained by vulcanizing a rubber composition containing a rubber component and short fibers, wherein a wax-containing lubricant is present on at least part of the friction-transmission surface.
