formation of joint as one of the joint zone. Joint group with the link layer allows a single vibration of V consistent with the formation of mutual non-elimination, and thus to minimize vibration, and through joint group to give the root to lateral rigidity and stability, thereby eliminating the vibration of a single phenomenon, between the horizontal direction with good stability and easy in operation and not interfere with each other out with, suitable for high power transmission. I produced the joint zone is made of high modulus cord, and composed of specially formulated neoprene compound, forming a sulfide, has good integrity. The bands are evenly, smooth operation, high load force transmission, long life is not easy turning with jitter and for the impact of fluctuating load and vibration of the occasion, especially for high straight drive shaft parallel to the ground.
