6.1.3
Chain and Sprockets
Check sprocket alignment periodically and correct misalignment immediately. Wear on the
inside sidebars or on one side of a sprocket is a definite indication of misalignment. On
indexing Gear Motor drives or Gear Motor drives equipped with brakes, special attention
must be given to drive sprocket mountings to prevent them from becoming loose and
shifting. After the initial startup inspection, make a careful check at 100 hours and another
at 500 hours. Set up a periodic inspection schedule thereafter based on operating
conditions. Indexing and braking drives require more frequent inspection than
conventional drive. Most conveyor drive chains operate in a semi-protected condition: it is
good practice to remove them periodically for cleaning and re-lubrication. Tight chains are
just as harmful as loose chains. For correct chain tension, the deflection on the slack side
should measure 2% to 3% of the sprocket center distance. For sprocket realignment see
“Drive Chain” under installation.
6.1.4
Flat Top & Friction Top Chain
In many application, rapid build-up of grease, dirt, grit, sand, spilled syrup and beverage
can occur.
Some Tabletop applications require continuous lubrication. (i.e., Stainless Steel Tops-
Roller Based Chain, etc.) This is of the most importance on the thrust faces at the
entrance of conveyor turns. A lubrication system that provides continuous
and uniform lubrication is recommended. If lubrication is not acceptable or
compatible with the application, a short break in lubrication application is beneficial. The
service life of side flexing chains and wear strips can be improved if sliding surfaces are
lubricated with a light material oil prior to installation. In the case of side flexing roller
chain, the base chain should also be oiled prior to installation.
Oil Base Lubricants-these are vegetable oil or mineral oils, which offer levels of protection
and lubrication to exposed chain parts. These should be used whenever practical on all
metal chains.
Water soluble Lubricants and soaps- these are excellent lubricants with many desirable
properties. Since water is a conveying medium, they are primarily suited for chain having
corrosion resistant parts or those with corrosion resistant top plates.
Water can be used as a lubricant, however, it is not considered as effective. If water is
used on plastic chains sliding on stainless steel pans, then drag on the chain may be
increased. A thin film of water must constantly be sheared as the chain slides over the pan
and overcomes the surface tension. Soap helps to overcome friction.
Applying the lubricant directly to the chin thrust face, directly below the flight just as it
enters the turn, may lubricate side-flexing chains. The lubricant can be applied under
pressure directly to the chain surface. Running the chain through a pan of lubrication on
the return strand can also lubricate the chain. The lubricant can drip on the chain from an
overhead storage tank.
