A lubricating system has been disclosed for gear mechanisms or generators, in particular for gear mechanisms of wind power plants, which lubricating system permits a switchover between dry sump lubrication and wet sump lubrication. This takes place by way of a delivery device which increases the pressure in a lubricant tank selectively or in an emergency, for example a power outage, and presses a lubricant back into an oil sump in the gear mechanism, whereupon a lubricant level is increased there and wet sump lubrication is realized. The delivery device can have a compressor. Said compressor can charge a pressure accumulator via a non-return valve or can increase the pressure in the lubricant tank directly. The delivery device can consist of hydraulic, pneumatic or else electrical components. If it is pneumatic, it can be separated from the hydraulic lubricating system via an elbow.

A dispensing system to apply grease to a lens holder is provided. The dispensing system includes a lens holder cavity adapted to accommodate a lens holder and a loading area. The loading area includes a damping grease cartridge to accommodate the grease. The dispensing system includes a nozzle apply a predetermined volume of the grease to the inner diameter of the threads. The dispensing system includes a first servo motor to control the height of the lens holder and a second servo motor to ensure a uniform dispense of the predetermined volume grease. The dispensing system is controlled by a programmable logic controller that includes a human machine interface panel adapted to control process parameters. The programmable logic controller and the human machine interface panel are adapted to modify dispensing time, rotation speed, rotation angle to regulate dispensing of the grease.
