How a crowned pulley keeps the belt tracking on it is a mystery to most people, so I thought I'd write a small article explaining how it actually works. The key to understanding flat belt tracking on a crowned pulley is to look at how a belt flexes when pulled more on one edge than another. ...
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 is used.
Conveyor pulleys Dodge DLAG: The best value in vulcanized lagging DLAG is a proprietary vulcanized rubber compound that has proven to dramatically extend pulley life in the toughest
6 System components In its simplest form, a belt conveyor consists of a driving pulley (often the head pulley), a tail pulley, the tensioning device, a conveyor belt, and the supporting structure with the belt support (slider bed or carrying rollers).
Magnetic pulleys are manufactured to CEMA standards and can be used in most any head pulley application. CEMA Class Permanent Magnetic Head Pulleys (PMG) • …
Snub Pulley Mounted close to the drive pulley on the return side of the belt, the snub pulley's primary job is to increase the angle of wrap around the drive pulley, thereby increasing traction.
Pulley diameters, shaft stresses, bearing loads, allowable turndown ratios, and other important design information is automatically calculated for each pulley. An accurate graphical representation for each pulley is displayed showing belt tensions, wrap angles, and the pulley geometry.
The pulleys described herein are those meeting standard specifications. They are by no means a limit to Continental's abilities in the enginee- red class applications as custom pulleys are designed and fabricated to meet customers individual requirements whenever necessary.

The HTD design requires substantial belt tooth to pulley groove clearance (backlash) to perform. As smaller diameter pulleys are used, the clearance required to operate properly is increased.
Drive/Head Pulley – A conveyor pulley used for the purpose of driving a conveyor belt. Typically mounted in external bearings and driven by an external drive source. Idler Pulley – Any pulley used in a non-drive position that is intended to rotate freely and be driven by the belt. Return/Tail Pulley – A conveyor pulley used for the purpose of redirecting a conveyor belt back to the drive ...

Both pulleys are a crown faced design for maximum pulley strength, balance and belt tracking. Both pulleys come complete with tapered bore hubs designed specifically for conveyor pulleys for dependable mounting of the pulleys to the head and tail shafts.
2008-03-23· 2. the tracking effect of the preceeding trough idlers generally will be higher than the tracking effect of the crown on a head pulley - an exception could be (say) a tripper where the unloaded belt and associated lift-off could benefit from a crowned pulley.
