Conveyor Lubrication System

conveyor lubrication systemsFor improved power transfer and reduced wear, corrosion and noise, a conveyor lubrication system can provide the solution. Lubrication that is interrupted or inadequate can cause conveyor chains to prematurely fail, disrupting production and forcing costly downtime.

DropsA is an industry leader when it comes to solving the industry’s most challenging lubrication issues. We are an ISO 9001-accredited company providing innovative chain lubrication systems and components. We design and manufacture advanced products that enhance productivity while meeting the highest standards of energy efficiency, environmental compliance and ease of operation.

Conveyors Driving Productivity

From mining and materials manufacturing to food processing and transportation, conveyor chains are vital to productivity. However, during their many thousands of hours of operation, these chains can experience recurring problems and failure.

Chain Failure Issues

According to Machinery Lubrication magazine, the most common types of chain applications, such as steel bushing and roller chains, typically experience three types of failure: tensile, fatigue and wear.

    Tensile failure results when a chain is overloaded, for example when too much weight is placed on a conveyor. The chain tends to stretch from the stress of tensile force to the point where it no longer functions properly or fails altogether.
  • Chain fatigue failure is the result of repeated loading at or below its rated yield strength. Although the chain does not stretch, microscopic cracks in the link plates and sidebars form that can eventually lead to failure.
  • Chain wear is the result of friction from surface contact or contact combined with corrosion. This steady removal of material continues until link plates and bushings have become so thin that they fail under load.

Chain wear, which is often seen between the pin and bushings, can cause the chain to grow longer without stretching. Over time, such wear causes the elongated chain to no longer fit the sprockets or to maintain proper spacing.

Productive Service

chain lubrication systemsAfter an initial, rapid period of break-in wear, a properly and timely lubricated chain can provide thousands of hours of productive service. It is generally understood that a correctly designed and operated conveyor lubrication system can extend the useful life of a chain by 100 times or more.

With any mechanical system, time in service takes a toll. For conveyor chains, a terminal stage of wear can be seen in pins and bushings that have nearly worn through or when elongation causes increased or uneven loads on specific joints.

When a chain does not receive adequate lubrication, wear increases. In addition to a loss of reliability, an ineffective or disrupted lubrication system can cause a chain to wear rapidly and unevenly, and it will experience increased friction and a damaging rise in temperature.

Lubrication reduces wear between pins and bushings. It also helps remove wear particles and other debris while reducing friction where the chain engages a sprocket. Likewise, a conveyor lubrication system can deter corrosion and helps transfer heat and mitigate impact shock.

Viscosity Balance

Conveyor chains should be lubricated by an oil with a viscosity low enough to penetrate to the inside of essential surfaces but high enough to preserve the friction-reducing film on surfaces under prevalent temperatures and pressures. Lubrication should be applied to the upper edges of the link plate or the sidebar along the lower span.
