Terms and Definitions
Good Evening Everyone....!!!
Today we shall discuss some most popular ''Terms & Definitions '' used in conveyor system.
Terms and Definitions
Bearing block – The block or housing that contains or supports a bearing.
Bed Section – The conveyor frame that supports the conveyor’s belt, drive, end units,carrying surface/rollers, etc.
Belt Cover – A rubber or PVC coating applied to a conveyor belt to protect the belt
carcass and/or provide special carrying capacities for the belt.
Belt Sag – Lack of tension or tautness in the conveyor belt that causes it to droop in areas between supporting members.
Belt Tension – The results of force applied to the conveyor that causes or trends to cause stress or stretching of the belt. All belts must be tensioned to some extent to provide proper driving force and tracking.
Belt Tracking – The path followed by the belt as it runs on the conveyor and around the conveyor pulleys.
Belt Wrap – The amount of contact between a belt and a pulley, or roller, measured in degrees.
Brake – A friction device used to bring conveyor components to a controlled stop and/or prevent them from moving once stopped.
Clutch/Brake - A coupling device normally mounted between a motor and a gearbox providing the benefits of a clutch as well as braking capacities. This arrangement allows a conveyor to be stopped without having to stop its motor which will improve the life of the motor.
Crown Pulley – A pulley having a face that is slightly tapered from the center to the ends, so that its diameter at the center is greater than at its ends. Used to assist in belt tracking.
Drive Pulley – The pulley that is connected to the drive gearbox by the drive chain and sprocket transmitting the rotational force provided by the arrangement to the conveyor belt. Driving force to the conveyor belt is provided by the amount of belt wrap on the drive pulley and the vulcanized lagging provided on the pulley.
Drive Sprocket – The sprockets used in the power transmission arrangement found in the conveyor drive unit. The sprocket sizes are selected to provide some mechanical advantage and give the desired conveyor speed from a given output RPM of the gearbox.
Frame – A structure supporting the machinery components of a conveyor.
Friction – Resistance to relative motion between two bodies in contact caused by the surface characteristics of the bodies at the point or area of contact, and the contact pressure.
Gravity Roller Conveyor – A series of rollers supported in a frame over which objects are advanced by gravity. Rollers are not powered by an outside force.
Head Pulley – A pulley used at the terminal end of the conveyor toward which the commodity is being conveyed.
Head End – The end of the conveyor toward which the commodity is being conveyed.
Idler Sprocket – An unpowered sprocket that supports, guides and /or changes the direction of a chain. Usually mounted on a shaft that in turn is supported by a bearing.
Power Transmission Belt – A belt that transmits power or motion from one rotating part to another.
Power Transmission Parts – Those parts or components by which power produced by the motor or gearmotor is conducted and applied to run the drive pulley of a conveyor.
Pulley – Consist of a steel tube with end plated, taper lock mounting hubs and bushing,and a steel shaft. Used for drive pulley, end pulleys and take-up pulleys.
Take-up Device – The arrangement of parts that applies tension to the conveyor belt,consisting of a take-up pulley or roller and a means for adjusting its position to create longitudinal stress in the belt.
V-belt – A drive belt having a trapezoidal cross section for operation degrees over grooved sheaves. Its shape permits wedging contact between belt side and grooves walls for transmission of power.
