The pulley consists of a belt or chain that is wrapped around two or more sheaves. The sheaves, or wheels, are usually made of metal and are either grooved or flat. Material and Production Process. Timing pulleys are usually made of aluminum alloy, steel, or stainless steel. The production process begins with the selection of raw material.
A belt conveyor can come in many shapes and sizes and have an almost unlimited amount of interchangeable components, not to mention the number of add-ons available. Selecting the belt conveyor that best fits the processing system at hand can be overwhelming. The reason for this is that conveyors are extremely versatile; they can be modified and …
Gearmotors with higher gear ratios can provide greater torque output, which is beneficial for handling heavy loads or overcoming significant resistance. On the other …
BELT CONVEYORS FOR BULK MATERIALS 1. INTRODUCTION: Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications.
Conveyor selection factor no. 2: Decentralized solutions. Conventional conveyor sections are powered by gear motors with 400 to 480 volts. These motors drive long flat belts that usually operate 24 hours per day, regardless of how many goods are being transported. A respective conveyor zone is switched on and off using pneumatic …
The speed ratio is defined as the ratio of the large to small pulley size and can be calculated simply by dividing the number of teeth in the large pulley by the number of teeth in the small pulley. With the calculation formulated in this way, the speed ratio will always be a value greater than 1.0, so the drive system designer engineer can ...

Gear ratio. i = If the rotor inertia and the gear ratio are unknown, the acceleration torque will be calculated with an inertia ratio of 5:1 (see the motor selection tips that will appear on the result window for the detail).
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.
