The average transmission ratio is accurate; (2) The initial tension of the belt is small, and the load on the shaft and bearing is small; Because the belt is thin and light. The strength of the strong layer is high, so the belt speed can reach 40m/s, the transmission ratio can reach 10, the structure is compact, and the transmission power can reach 200kW, so it is increasingly widely used;PRODUCT INTRODUCTION The Top and bottom are encased by the wrapper ,Both sides are rubber v belt of tooth shape groove is designed for the bottom to improve the flexural property PRODUCT FEATURES Large intensity ,High Fiexibility ,Good Durability Special bottom rubber used ,small elongation and long service life Excellent heat -resistance ,Oil -propt and wearing resistance High transmission efficiency suitable for band pulley with minor diameter a safe performance can be guaranteed even during high -speed operation
