Abstract: 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.

Abstract: An apparatus as described for transmitting rotational energy from a prime mover having a first shaft to a torque load driven by a second shaft through a spur gear train. A splined shaft (30) having a sun gear (32) at one end is coupled to the prime mover. The sun gear (32) meshes spur-wise with three compound star gears (50). These star gears are positioned at approximately the same distance from the axis of the splined shaft.

Preferably the sun gears and the star gears are fully crowned and machined to have a high contact ratio such that at least two pairs of gear teeth of each mesh are substantially in contact at all times. Because one end of each quill shaft is supported by the compound star gears, the pitch circles of the associated sun gear and star gears are substantially tangent to each other thereby minimizing vibration, noise, and stress.

The ring gears have mutually opposed lubricated abutment surfaces whereby respective transverse forces arising effectively at the centers of the running teeth and acting parallel to the common axis are countered by oppositely acting respective reactions exerted by the ring gears mutually one upon the other.
