Lubrication Effects on Chain Operation

The majority of chain drives and conveyors will perform better and last longer when timely and adequate lubrication is provided. One rule-of-thumb is that proper lubrication can extend chain life by as much as 100 times.

Even if overall chain life is acceptable, lack of proper lubrication can cause other problems. When a chain is starved for lubrication, wear from one joint to another can vary greatly, causing erratic action. Rapid joint wear can cause early loss of timing in a conveyor. Lack of lubrication can increase friction and power consumption and cause a harmful temperature rise.

Need for Lubrication

Chain lubrication is needed mainly to slow the wear between the pins and bushings in the chain joints, to flush out wear debris and foreign materials, and to smooth the chain’s engagement with the sprocket. Additionally, lubrication may be needed to inhibit rust and corrosion, to carry away heat, and to cushion impact forces.

Chain Lubricants

A chain lubricant should have low enough viscosity to penetrate into critical internal surfaces and high enough viscosity, or necessary additives, to maintain an effective film at the prevailing temperature and pressure. Recommended viscosity for various surrounding temperature ranges are shown in Table 1. The lubricant should have the capability to maintain the desired lubricating qualities under prevailing operating conditions, and be clean and free of corrodents.

A good grade of nondetergent petroleum base oil usually is acceptable. While detergents are not normally needed, antifoaming, antioxidizing and extreme pressure additives are often helpful. Impure oils should be avoided. Acids or abrasives in the oil can permanently damage the chain.

The chain manufacturer often uses grease or petroleum jelly as an initial lubricant. However, users generally should not apply greases to chains in service because they are too thick to penetrate into the internal bearing surfaces of the chain. Users should use grease only when fittings for injecting the grease into the chain joints are provided.

  • Lubrication of Chain Drives

The recommended method of lubrication for chain drives is indicated in the power rating tables published in ASME B29 Series Standards and in various manufacturers’ catalogs. The methods normally listed are manual, drip, oil bath, slinger disk and oil stream. In all methods, the oil should be applied to the upper edges of the link plate or sidebar in the lower span of the chain. This enables gravity and centrifugal force to carry the lubricant into the critical bearing areas.
