CENTRALISED REDUCTION GEAR LUBRICATION SYSTEM Russian patent published in 2013 - IPC F16N7/32 

FIELD: machine building.

SUBSTANCE: system is intended for lubrication of different parts of machines being in movable contact, and namely to lubrication of engagements, rolling bearings of reduction gears of drives of mining machines. The system includes a pump, an oil tank, a pressure pipeline and a drain pipeline, which are led out of it, mixing devices with three channels, at that, two of them are inlet channels and one channel is an outlet channel, an oil supply system to friction assemblies and a control unit. It is equipped with acoustic emission sensors installed on the reduction gear housing and connected to a multichannel control unit of information data channels, heating and cooling devices, each of which is connected on one side to the pump from the oil tank through a filter element, and on the other side through a separate main oil pipeline to mixing devices, each of which is connected to a system of distributing tubes to individual bearing assemblies and gear transmissions of the reduction gear. Each mixing device is equipped with two controlled throttles installed on the connection of each main oil line with the mixing device and connected to the control unit of the information data channels.

EFFECT: enlarging the capabilities of the device and obtaining a constant value of acoustic emission of the reduction gear within the specified limits.
