Website set up. When the sheaves are not properly aligned, the cable will attempt to “crawl” up the sides of the sheave wheel grooves. This action can result not only in distorting the sheave grooves but can also introduce additional torque in the cable. The materials used in the construction of sheaves has changed over the years. WebPulleys with grooved rims are called sheaves. In belt drive, pulleys are affixed to shafts at their axes, and power is transmitted between the shafts by means of endless belts running over the pulleys.
