How Crowned Pulleys Make Belts Track | Mechanics and Machines
Nov 17, 2014 · Most people interested in machines know that adding a slight crown to a pulley tends to keep flat belts centered. But it is not obvious how it works. As shown in the sketch above, introduction of a slight crown to the pulley causes the belt to bend when it is displaced laterally. Consider a point … Continue reading How Crowned Pulleys Make Belts Track →

The face length of a conveyor pulley is a derivative of the conveyor belt width. In bulk handling applications, an adequate pulley face length is one that is 2” or 3” greater overall or 1” to 1.5” greater on each end than the overall width of the conveyor belt. Unit handling applications may warrant deviation from these guidelines.
Pulley Crowns. Crowning one or several pulleys in a belt system is the most common way of tracking a belt. For flat power transmission belts and narrow conveyor belts (up _ to _ 8 _ in.), a radius crown...

2018/10/04 · A concave crown is seldom used unless there is a very special reason to do so. Even on troughed conveyors, flat face and crowned pulleys are generally used. On pulleys with < 24” face width, some engineers prefer a convex crown pulley shape. Others prefer a straight taper with center flat.
In a simple language, a crowned pulley is a pulley which has two tapered edges which helps the belt drive to run without wobbling and with much higher efficiency. It also helps in increasing stability when...

The use of crowned pulleys normally requires that the conveyor be capable of sustaining pre-tension belt elongation values of approximately.3% or greater. Tension values below this may result in inadequate lateral steering forces, as well as belt elongation, which can cause slippage of belt on pulley.
