US 2006/0076193 A1 · Apparatus and method for lubricating and cooling gear mechanisms

Abstract

A device for lubricating and cooling gear mechanisms has a supply line for supplying lubricating and coolant oil from an oil sump into a first channel in a spray pipe. The first spray channel connects to at least one first nozzle for the targeted spraying of the lubricating and coolant oil into areas of the gear that require extensive lubrication and that are allocated to the first channel. The supply line is connected to a second channel and one or more second nozzles connected to the latter for spraying the oil in areas that require extensive lubrication and are allocated to the second channel. The channels are prioritized with regard to more or less critical regions of the gear mechanism. A control valve that is responsive to a back-pressure in the spray pipe actuates the channels to supply the gear mechanism in accordance with the prioritization of the regions.

Dependent claims

An apparatus for lubricating and cooling a gear mechanism, comprising:

a feed line for feeding lubricating and cooling oil from an oil sump;
a spray tube having a first channel formed therein communicating with said feed line;
at least one first nozzle communicating with said first channel for targeted spraying of the lubricating and cooling oil into lubrication-intensive regions of the gear mechanism associated with said first channel;
said spray tube having at least one second channel formed therein communicating with said feed line;
at least one second nozzle communicating with said second channel for targeted spraying of the lubricating and cooling oil into lubrication-intensive regions of the gear mechanism associated with said second channel;
and
a control valve for selectively switching said first and second channels by back-pressure acting thereupon in a first valve position, wherein said first channel is active and said second channel is closed, and a second valve position, wherein said first channel is active and said second channel is active.

A method of lubricating and cooling a gear mechanism, the method which comprises:

feeding lubricating and cooling oil from an oil sump via a feed line to a first channel of a spray tube;
spraying the lubricating and cooling oil in a targeted manner, through at least one first nozzle connected to the first channel, into first lubrication-intensive regions of the gear mechanism assigned to the first channel;
feeding lubricating and cooling oil to at least one second channel via the feed line;
spraying the lubricating and cooling oil in a targeted manner, through at least one second nozzle connected to the second channel, into second lubrication-intensive regions of the gear mechanism assigned to the second channel;
and
switching a control valve communicating with the first and second channels by way of a back-pressure acting thereon into a first valve position, wherein the first channel is connected to the feed line while the second channel is closed, and into a second valve position, wherein the second channel is connected in addition to the first channel.
