Flocking-ribbed belt

One of the shortcomings of ribbed belt drive transmission is relatively noisy, low-speed or velocity changes in the use of faster, and after a period of time, wedge-wear, hardening and tension relaxation, or in the rain Tiandao water, transmission would be given harsh screams, the NVH performance of the vehicle. One solution is left wedge of 0.1-1.0 mm high-intensity short fiber (such as aramid, PBO fiber, etc.). Because fiber friction coefficient stability, a sound-absorbing function, thus greatly reducing the noise-ribbed belt drive.

Flocking general with special ribbed belt grinding process to achieve. Grinding, rapid ground into a first wedge broad wedge, and then slow wet grinding, rubber Modiao, wedge-exposed certain length of the fiber.
