Understanding Pulleys violafiredept
Pulleys and angles Our fourth Principle tells us that when the angle of the ropes running through a pulley are at 0 degrees the force will be doubled When the angle of the running lines is not 0 degrees, the effectiveness of the pulleys is diminished We can use this knowledge to our advantage We often incorporate cod pulleys into our systemsA Drive Pulley or Head Pulley is used for the purpose of driving a conveyor belt They are normally mounted in external type bearings and driven by a motor and reducer Conveyor head pulleys can be flat faced or crowned and many have lagging to reduce belt slippage Conveyor drum pulleys, wing pulleys and spiral pulleys are the most common Conveyor Pulley: Head, Tail, Drum and Belt pulley For rope wrap angle of 180° For rope wrap angle of 90° Groove Tmax = 2000∙r∙Dt Tmax =2828∙r∙Dt Bore Tmax = 2000∙B∙LTB Tmax = 2828∙B∙LTB Note: For a sheave ratio greater than 18:1, calculate only bore pressure nylatech 8005069566 Load Capacity for Nylatech Sheaves: with Bearings 180° Wrap Angle 90° Wrap AngleSHEAVE DESIGN MANUAL NYLATECH
