The invention provides a compact gear installation in which all the necessary auxiliary equipment for pressure lubrication is accommodated within a gear housing. Also, damage to the gear caused by insufficient lubrication during run down or start-up of the gear is avoided. Within the housing, an oil pump pumps lubricating oil from a lower cooled oil reservoir via a filter to an upright oil reservoir. Oil flows out of said upper reservoir via two main pipes, which subsequently interconnect, to lubricate the gear. When the gear is switched off the lower of these pipes is sealed off, e.g. by a valve, but a certain volume of oil can still flow through the upper pipe to lubricate the gear as it slows down. When the gear is started up again, the lower pipe is reopened and the residual volume of oil (below the level of the upper pipe) can flow through this pipe to provide initial lubrication for the gear.
