The invention relates to a lubrication device for a turbine engine, comprising an oil intake pipe (23) provided with a pump (24) for supplying oil and control means (25) located downstream from the supply pump (24), a supply pipe (26) intended for supplying oil to a member to be lubricated and a recirculation pipe (27), the control means (25) making it possible to direct all or part of the flow of oil from the intake pipe (23) towards the supply pipe (26) and/or towards the recirculation pipe (27), the pump (24) being driven by at least one rotary member of an accessory gearbox of the turbine engine.

A mobile lubrication pump has a motor for driving the pump for producing a pump pressure, a pressure monitor for measuring the pump pressure, a motor controller for regulating the operation of the motor, and a data processing unit (DPU) for communicating with the motor controller, and for receiving: 1) input from the pressure monitor, and 2) user input related to pump capacity and/or lubrication target. The data processing unit is configured to determine and communicate a motor speed and/or motor torque to the motor controller based on the received input 1) and 2).

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.
