Types for Chain Drives

Three types of lubrication are shown in the horsepower tables for roller chain, engineering steel chain, and silent chain in chapters 5, 6, and 7. They are 

Note Manual lubrication is to be done only when the drive is stopped and power to the drive is locked out. 

For manual lubrication, a person applies oil to the chain with a brush or a spout can. Oil should be applied to the chain once each eight hours of operation. The time may be longer if it has been found adequate for that drive. The amount and frequency of applying oil to the chain must be sufficient to prevent a red-brown (rust) discoloration of the oil in the joints. That discoloration tells the user that the lubrication is not adequate. 

For drip lubrication, oil is continuously dripped onto the upper edges of the link plates, or sidebars, from a drip lubricator. The drip rate ranges from 4 to 20 or more drops per minute. The drip rate 

The diameter of the disk should give a rim speed between 600 ft/min and 8000 ft/min. Lower speeds may not pick up the oil effectively. Higher speeds can cause oil foaming and overheating.
