Abstract

A flowable lubricant is metered in pulses to a chain drive under the control of the computer programmed to respond to measurement of the chain drive speed so that, when the speed of the chain drive is below a threshold level above which centrifugal force can cause loss of lubricant, the lubricant can flow in pulses to the chain drive. When, however, the speed of the chain drive rises to the threshold value, the pulse dispenser is blocked and the supply of lubricant pulses is terminated. The lubricant pulses which are not supplied during the interval are stored. When pulse supply of lubrication is restored, the stored lubricant pulses are supplied.
