Of the following, the one method of lubrication which is NOT commonly used for an encased chain drive is _________ lubrication.

Oil bath lubrication
Grease lubrication
Gravity tank lubrication
Drip feed lubrication

The correct answer is: Gravity tank lubrication

Gravity tank lubrication is not commonly used for an encased chain drive because it relies on the gravitational force to dispense lubricant, which may not provide a consistent application needed for the continuous operation of a chain drive system. Encased chain drives typically require a more controlled method of lubrication to ensure that the lubricant adequately reaches all the moving parts and maintains efficiency. In contrast, oil bath lubrication involves immersing components in oil, which helps in reducing friction and keeping the chain properly lubricated. Grease lubrication is often used due to its ability to adhere to surfaces, reducing the frequency of reapplication while providing adequate protection against wear. Drip feed lubrication offers a steady supply of oil, allowing for targeted application that can maintain the necessary level of lubrication over time.
