Chains & Conveyors

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メ 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. The method of lubricating chain conveyors is generally governed by speed, environment and accessibility. Some method of continuously or periodically lubricating the chain conveyor in service should always be considered. Not lubricating a chain conveyor is a reasonable option only if one of the special chains (sealed joint, etc.) is used.

Manual lubrication is normally sufficient for slow-speed conveyors. Manual lubrication may sometimes be adequate for moderate-speed conveyors, but drip or brush lubrication is often needed. Drip lubrication is often required for high-speed conveyors, and continuous oil stream lubrication may sometimes be needed. Whatever the method, 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.
