Inspection Checklist

Lubrication

-Manual: Carefully follow lubrication schedule.

-Drip: Inspect the filling of oiler cups and the rate of feed. Check that the feed cups are not clogged and are properly positioned over the chain. -Bath: Inspect the oil level and check that there is no sludge. Drain, flush, and refill the system as the application requires.

-Automatic: Inspect grease lubrication reservoir and fill accordingly. Manually grease joints periodically to ensure proper grease injection from system.

If the chains have not been lubricated properly, the joints may have a brownish (rusty) color. The pins may also be roughened, grooved, or galled with a permanent staining of the material due to breakdown of lubrication. Properly lubricated chains will not be discolored at the joints; they will appear brightly polished with a high luster.

Check link plates and sides of sprocket teeth for wear, which indicates misalignment.

Check shaft and sprocket alignment to prevent wear.

The Pro-Align™ Laser Alignment System uses advanced laser technology to ensure precise chain-sprocket

interaction for maximum performance.

Check wear on the working faces of sprocket teeth.

These faces should develop a bright, polished appearance as the system runs. Scratches, galls, grooves,

or visible changes in tooth form may be caused by lubrication failure or overloading.

Check and adjust chain tension.

An elongation of three percent (3%) or more indicates that the chain is riding near its limit of allowable height on the sprocket teeth. A gradual increase in chain length is the result of normal wear. A sudden increase in slack indicates one or more of the following:

-Lubrication failure

-Excessive overloading or shock

-Displacement of shaft bearings

-Displacement or failure of take-ups

Check that the chain is free from dirt, grit, or other abrasive material.

Clean the chain periodically.

Check guides, tracks, and areas below the conveyor for buildup of dirt or material that will cause interference or binding of the chain.

Entry and exit points of guides and tracks must permit the chain to pass with a minimum amount of impact or interference. Check that chain tracks are not over-lubricated or contaminated, which can force the rollers to slide rather than roll.

Inspect apron and pan bead openings.

If the beads have been wedged apart or otherwise distorted, fine material may bleed into moving parts and

cause excessive wear.

Roller Conveyor Components

Strong, Long-Lasting Pins

Every pin is built from high-grade carbon or alloy steel to stand up to the most rugged conditions. Each is available in through-hardened, case-hardened, and induction-hardened treatments to extend the service life even more. And we take the utmost care to ensure a smooth bearing surface and proper sidebar fit for trouble-free operation.

Smooth Bushings

Our carbon and alloy-steel bushings are carburized and case­hardened using computer-controlled furnaces. The result is high surface hardness for excellent wear resistance with a tough core. We carefully control bushing dimensions to provide a uniform bearing surface and precise sidebar fit so your system runs smooth and strong. Stainless steel bushings are also available.

Reliable Rollers

A variety of steel grades and treatments means we can provide the right roller for your application. Our standard rollers are built from carburized, case-hardened carbon or alloy steel. You get a hard bearing surface with a ductile core for greater strength and durability. Rollers are also available in stainless steel, powdered metal, Hytrel, Delrin and UHMW plastic, and with plastic insert sleeves.

Precision-Manufactured Sidebars

Union® manufactures sidebars to stand up to tough operating conditions. Our standard sidebars feature special-grade carbon or alloy steel for long-lasting performance. Heat-treated sidebars provide even greater strength and durability. Stainless steel sidebars withstand corrosive and high-temperature environments. We carefully control pitch and hole size in every sidebar style to ensure our chains and sprockets articulate correctly, extending the life of both. A wide variety of attachments are also available to meet your specific needs.

Choosing Metal Thickness

Experience is usually the best guideline for specifying the metal thickness for pans and aprons. Make sure you consider the following points:

1.

Number of chain strands to be used.

2.

Required service life.

3.

Manufacturing restrictions.

4.

Weight of each apron support. Deflection must be limited to prevent binding between overlapping pans.

5.

Corrosive and abrasive properties of conveyed materials.

Built to Last

The service life of Union Roller Conveyor Chain will last years with proper care and maintenance during operation. Consider the basic chain loading requirements of your application when selecting chain.

Basic Chain Loading

Ultimate Tensile Strength. Chain will break at or above this level.

80%

70%

Yield Strength. This load exceeds a chain's elastic limit, causing permanent deformation.

50%

40%

30%

Endurance Limit. Chain will withstand load 20% peaks at this level indefinitely.

Rated Working Load. This load is based on “X” the joint bearing area multiplied by the allowable bearing pressure.

Working Load is equal to bearing area (pin diameter multiplied by bushing length) multiplied by the allowable pressure for the materials involved. The nominal value for allowable pressure is 3500 psi. At this level, a chain will wear out by elongation rather than break.

Chain can be expected to experience ultimate wear performance when actual chain pull does not exceed the Rated Working Load. Relative life expectancy varies by application.

Maintenance Checkpoints

Checkpoints Comments

Centering A guide rail is essential to ensure proper centering of the conveyor. If centering is not accurate (with no side guide rail), scrubbing of the sidebars will occur which results in shorter conveyor chain life and/or possible chain failure.

Sprocket alignment When two or more sprockets are installed in a row, be sure to align the position of the sprocket teeth. If the sprocket teeth are not properly aligned, the working load will not be equally divided and will cause the chain to twist. To align sprockets quickly, easily, and effectively, contact U.S. Tsubaki for information about the Pro-Align™ Laser Alignment System.

Take-up If take-ups on both sides are uneven, the conveyor chain will not engage smoothly with the sprocket.

Initial chain tension Maintain adequate chain slack. If chain tension is too high, loss of power will result. This is a dangerous situation and, if too loose, the chain will climb the sprocket.

Break-in The first running of the system after installation should be made under no-load conditions. Run the system through several cycles while listening for noises which may indicate obstructions and/or problems within the system. After inspection, continuous operation may begin.

Stopping conveyor Stop the conveyor under no-load conditions to prevent remaining material from overloading the system when the conveyor starts again.

Lubrication Lubricate conveyor chain periodically. Lubrication of reducers, bearings, and other components is also essential.

Securing conveyor parts Parts fastened to the conveyor, such as buckets, aprons, slats, etc., may loosen due to vibration. Fasten nuts and bolts securely and check periodically.

Amount of chain slack Chain slack varies per application. Regularly check and adjust the amount of chain slack based on visual inspection during actual run and downtime. Consult troubleshooting guide when required.

Use and maintenance record After installing the conveyor, prepare a record of the expected capacity to be conveyed, conveyor speed, r.p.m. of main shaft, electric current, voltage, working horsepower, actual conveying capacity, inspection date, lubricating date, details of troubles, etc. This record will serve as protection against unexpected problems and will be helpful during maintenance and repairs.
