Light Belt Conveyor Installations – Engineering Guidelines Edition: January 2008, replaces edition April 2003 7 2. Belt conveyor components In its simplest form, a belt conveyor consists of a supporting structure with belt support (slider bed or carrying rollers), a driving pulley, normally the "head" pulley, an idler roller, usually the
- A conveyor belt must run "True" to avoid damage to the edge of the conveyor belt. RULE 1 The basic and primary rule of tracking a conveyor belt is simply "The belt moves towards that end of the roller it contact first." The conveyor belt will travel where directed if it has been manufactured, slit and spliced correctly. RULE 2

If your conveyor belt system has idler rollers, make sure the conveyor rollers are all turning appropriately and are square to the proper pulley frame. Store conveyor belts correctly: It is common for industries to stock conveyor belts in their production plant for the belt failure emergency.
11. Conveyor take-up. Belt conveyor includes take-up device to maintain proper tension in belt. The 'proper' tension implies 'minimum' tension to fulfil all the functional needs such as:-Adequate tension to transmit mechanical power from drive pulley/s to belt in all operating conditions.
What is claimed is: 1. A conveyor system comprising: a frame; a continuous belt about the frame in a catenary take-up arrangement having an upper conveying portion and a lower return portion; a drive means for driving the belt in forward and reverse; and a take-up means for engaging with the return portion of the belt so that the belt is capable of running in forward and reverse; and a ratchet ...

A conveyor construction that includes a conveyor frame assembly formed from a pair of spaced side frame members interconnected with each other by spaced cross members. The upper bed of the conveyor frame assembly is formed from individual bed plate strips attached to each of the cross members. The width of the conveyor frame assembly can be modified by the proper selection of the …

• Flange Roller LLimit the drive sprocket engagement to 180° or less. • Install position limiters in line with each drive sprocket (on flat belting), located on the drive sprockets at 165° of belt wrap. • Guide the belt with edge rails or containment blocks on both the returnway and carryway
a belt clamp, mounted on the conveyor structure, through which the belt is threaded. Where the slope is very long, additional clamps should be spaced approximately 1000 feet apart. Where more than one clamp is used, workers are stationed at each clamp to loosen and tighten the clamps as the belt is fed onto the conveyor. Care must be
The wrap factor can be as small as 0.08 for dual drive systems with rubber-lagged drive pulleys an automatic take-up and 420 of wrap angle or as large as 1.2 for a single drive system an unlagged pulley manual take-up and 180 of belt wrap.
The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.
They have a welded. construction and are available in 45°, 90° and 180° curves. Nose Roller Belt Curve conveyors are used to convey small products of various sizes and shapes. They help maintain the proper product orientation and provide positive traction through the curve. The belt guiding system is quiet and requires low maintenance.
The math is not as difficult as it appears. Here's the logic behind the center-to-center distance formula: 2C: Multiplying the center-to-center distance by 2 accounts for the belt length on the top and bottom of the pulleys Note: The pitch created by differing pulley diameters is addressed later in the equation. (D+d ÷ 2): This accounts for the belt length "wrapped around" the outer ...
A loss of lagging material off a drive pulley will cause a belt to swing on the track. It can move from the right to the left. If you find that you have to adjust a roller in the opposite way as described before, so if you tighten on the right side and the belt moves to the right, it is a sign that your belt …
When reducing counter weight to relax conveyor belts in concave curves or just to get the proper sag on rollers for tracking, it is imperative that the drive pulleys on the conveyor be lagged with a 60 durometer rubber material to prevent slippage of the conveyor belt on the drive pulley. ... Snub drive pulley to increase the pulley wrap factor ...
5 CONVEYOR PULLEY SELECTION GUIDE Pulley/Core Diameter – The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter – The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width – The length of a pulley's cylindrical body.This area is intended to act as the contact surface for the conveyor belt.
Continental welded steel conveyor pulleys with a.D. hubs and bushings.,-The 3/4" per foot taper of the 0.0. provides a 32 to 1 locking ratio on the shaft.
A Sprocket Drive utilizes a sprocket with an integral shear pin hub which engages and drives the power chain of an overhead conveyor system. For use in horizontal turns, a sprocket drive requires a 90 degree chain wrap as the minimum with 180 degree chain wraps often used.
For short and wide conveyors, plastic modular belts are common alternative to traditional fabric belts. Plastic modular belts are sprocket driven, and thereby positively located by the fixed position of a drive sprocket. For the design of modular belts, the conveyor's …

Problem Solving | Conveyor Belting. 1. Conveyor runs to one side at given point on structure. Idlers or pulleys out-of–square with centre line of belt; readjust idlers in affected area. Conveyer frame of structure crooked; straighten in affected area. Idler stands not centred on belt: readjust idlers in affected area.
The biggest nemesis to a conveyor belt working properly is contamination. Contamination most commonly comes in the form of product debris, worn pulley lagging, grease, and loose bolts inside of the conveyor frame. It's critical when you remove your old belt to take the time to clean the frame. Once the conveyor is clean, it's time to ...

If wear patterns are identified, inspect the conveyor frame for catchpoints, sharp edges, or other objects that are rubbing against the belt. DRIVE SPROCKET AND IDLE SUPPORT WHEEL INSPECTION • Inspect the drive sprocket profile and the bore for wear. • Ensure all sprockets and support wheels are secured and proper spacing is maintained
Tip: Make at least one pulley in the belt drive adjustable to allow for belt installation and tensioning. Also note that in a properly designed belt drive, there should be a minimum of six teeth in mesh and at least 60° of belt wrap around the drive pulley. Other tips: • Pretension belts with the proper recommended tension.
