The design of the synchronous belt cladding purpose

by:Uliflex     2020-11-27
In order to protect the synchronous toothed rubber from wear and tear, the synchronous belt deformation of tooth surface covering a layer of wear-resistant nylon gauze. Asked the cloth weft elongation (> 130%) More than 8 kN / 5 em, in order to meet the needs of the production process. By material nylon cloth woven bag in operation of synchronous belt damaged, need to use industrial nylon raw silk cloth, its high tensile strength, abrasion resistance, tear resistance. But poor heat resistance of nylon, by 50 h under 120 ℃ degradation phenomenon began to appear, to a 30% drop in 400 h strength by 70%. In synchronous belt curing conditions under 180 ℃ for 30 min, general intensity fell by 15%, and in order to increase the elongation and nylon fabric with chlorofibre or spandex added under the condition of the strong fell by around 50%, the serious influence the service life of the synchronous belt. Polyester fiber and aramid fiber had good heat resistance, 400 h under 120 ℃ puissant drop within 10%, suitable for the requirements of the synchronous belt, so now instead of the nylon fabric with polyester fiber and aramid fabric tend to do cloth tooth bread. To better protect rubber synchronous belt, the designed li provides a double dens draconis package cloth, it is suitable for automobile engine synchronous belt, plays a role of resistance to wear and tear of its outer cloth, lining cloth of shearing effect, while the middle rubber as buffer layer. The designed li provides another new tooth cloth fabric, the fabric warp consists of a curling synthetic fiber, or by an elastic yarn ( Spandex) As the core yarn, outside its bound to huddle up new type of synthetic fiber yarn; Weft consists of synthetic short fibers twisted yarn, especially by between aramid short fibre form J twisted yarn. Its surface with a large number of villi, suitable for manufacturing automotive synchronous belt and other requirements strictly synchronous belt, the tooth cloth can improve the service life of the belt, and make the transmission noise gets a xiao control.
