Dear sir pulley shell dia selection and shaft design are very easy and most of the conveyor designers design the same. Pulley systems are used to provide us with a mechanical advantage, where the amount of input effort is multiplied to exert greater forces on a load. The goal is to increase the cfm from 3000 cfm to 4000 cfm. The pulley hub is defined as the internal, rotating, clamping component that connects the pulley to the shaft. Sheave width is the major factor in how large a rope a pulley can handle, wider sheaves handle larger ropes. This class is recommended for use with up to 220PIW conveyor belts. If you’ve ever flicked a light switch on and off, you’ll immediately understand how it works. When a upward force, F is applied by the hand, the movable pulley moves up alongwith the load L. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The most comfortable way to use a single moving pulley is combine it with a fixed pulley, seen below. RPM Pulley Calculator 2. Center distance is the distance between the two pulleys' centers. This lab will let you examine the relationship between the number of pulleys used and the force required to lift a mass at a slow steady speed. The most common approach is to mate a pre-made Trigger Wheel to the existing OEM crank pulley. Slide the other pulleys in the same orientation (lock screw facing up). They are often used to lift heavy objects: pulling down on one end of the rope creates an upward pull at the other end. PSTRESS Pulley Design Software. I notice that the top and bottom pulleys are not equally spaced and the up cables are no the same length as the down cables. Plastic pulleys have fins in sidewalls that should not be cracked or broken. The text is clearly written, though the photos and design are a little dated. PRO DUTY® PULLEY.
