Making a Solid Model of a V-belt Pulley

Flexible connector drives are simple devices commonly used to transmit torques and rotational motions from one shaft to another. Power is transmitted by a flexible connector (belt) placed on pulleys that are mounted on these shafts to reduce peripheral forces. The transmission ratios of torques and speed at the driving and driven pulleys are ascertained by the ratio of pulley diameters. A system of belt pulley drive, drawn using AutoCAD solid models, is shown in Fig. 10.1. The figure clearly explains how the belt transmits motion from the driving shaft (may be attached to an ...
