| 474265000 | Having trapezoidal cross section (e.g., "V-belt", etc.) | 9 |
| 20100069190 | TRANSMISSION BELT AND PROCESS FOR PRODUCING THE SAME - An object is to provide a transmission belt which is restrained from being deteriorated in a high-temperature atmosphere, is excellent in softness in a low-temperature atmosphere, and is hardly worn away. To attain the object, the invention provides a transmission belt made of a rubber composition wherein the ratio by weight of a Ziegler-Natta catalyst type ethylene/α-olefin copolymer rubber, which is an ethylene/α-olefin copolymer rubber obtained by polymerization in the presence of a Ziegler-Natta catalyst, to a metallocene type ethylene/α-olefin copolymer rubber, which is an ethylene/α-olefin copolymer rubber obtained by polymerization in the presence of a metallocene catalyst, is from 50/50 to 90/10. | 03-18-2010 |
| 20110028258 | HIGH LOAD DRIVE V-BELT - The present invention aims at improving the shock resistance of a block while reducing the noise of a belt running. A high-load drive V-belt B includes: at least one tension band | 02-03-2011 |
| 20110237377 | HIGH LOAD TRANSMISSION V-BELT - In a high load transmission V-belt, a plurality of blocks | 09-29-2011 |
| 20120202634 | DOUBLE COGGED V-BELT FOR VARIABLE SPEED DRIVE - A double-cogged V-belt with the upper and lower cog profiles symmetric and having lines (“L”) and arcs (“A”) connected according to a sequence from the center of a root to the center of an adjacent cog of L | 08-09-2012 |
| 20130040772 | POWER TRANSMISSION BELT AND METHOD OF PRODUCING THE SAME - To provide a power transmission belt and a method of producing the same that allows lightweight elements to be produced at low cost and allows the durability to be sufficiently ensured, the power transmission belt includes a plurality of elements each having both side end surface portions, a rocking edge portion rockably engaged with either one of a pair of other elements neighboring the element, and a concave-convex engagement portion engageable with the pair of other elements, in which each of the elements has a plate-like portion, a first convex portion projecting from one surface of the plate-like portion, and a second convex portion projecting from the one surface of the plate-like portion in a spaced relationship with the first convex portion to constitute the rocking edge portion, and each of the elements is engaged with the pair of other elements so as to press against one another by the first convex portion and the second convex portion. | 02-14-2013 |
| 20140364262 | V-Ribbed Belt And Method For Manufacturing Same - A V-ribbed belt that includes a ribbed surface covered with fabric is provided. The fabric is stretchable in two predetermined directions. A method for manufacturing the V-ribbed belt is also provided. The method includes placing a belt matrix about a mandrel, placing a fabric about the external circumference of the belt matrix which wraps around the mandrel, placing the mandrel inside a shell having a plurality of grooves on the internal circumference, expanding the belt matrix and the fabric toward the internal circumference of the shell and thus pressing the fabric onto the internal circumference having the multi-ribbed structure, and curing the belt matrix with the fabric. The fabric is stretchable to accommodate itself to the multi-ribbed structure. | 12-11-2014 |
| 20140378256 | V-RIBBED BELT - The present invention relates to a V-ribbed belt to be wound around plural pulleys and used, including an extension layer that forms a back surface of the V-ribbed belt, a compression layer provided on one surface of the extension layer and having plural ribs extending parallel to each other along a longitudinal direction of the V-ribbed belt, and a load carrying cord embedded between the extension layer and the compression layer along the longitudinal direction of the V-ribbed belt, in which a distance from an outer peripheral portion of the load carrying cord on the rib side to a tip portion of the rib is from 2.0 to 2.6 mm, and a distance from the outer peripheral portion of the load carrying cord on the rib side to a bottom portion of the rib is from 0.3 to 1.2 mm. | 12-25-2014 |
| 20150105198 | POWER TRANSMISSION BELT AND METHOD FOR FABRICATING THE SAME - A power transmission belt includes a transparent or semitransparent sheet material covering a portion of a surface of a belt body including a mark. At least a portion of the belt body covered with the sheet material is made of a rubber composition vulcanized with sulfur. The sheet material is made of a rubber material containing a diene rubber. The sheet material is vulcanized with sulfur together with the rubber composition forming the portion of the belt body covered with the sheet material such that the sheet material is connected to the belt body. | 04-16-2015 |
| 20160053851 | V-RIBBED BELT - The present invention relates to a V-ribbed belt containing an extension layer forming a belt back face, a compression layer provided on one side of the extension layer, and a tension member embedded between the extension layer and the compression layer and extending in a belt circumferential length direction, in which the compression layer has a plurality of V-shaped ribs formed to be extending in the belt circumferential length direction and to be a frictional power transmission surface with a pulley and the frictional power transmission surface is covered with a knitted fabric, in which the knitted fabric is knitted out of a polyester-based composite yarn and a cellulose-based natural spun yarn, the polyester-based composite yarn is a bulky yarn, and a knitting ratio of the cellulose-based natural spun yarn is not less than a knitting ratio of the polyester-based composite yarn. | 02-25-2016 |
