Abstract

An apparatus for lubricating a non-pressurized gearbox includes a low-to-high lubricant level sensor configured to sense a static level of a lubricant within the gearbox and to display the static level of the lubricant.

Claims (27)

1 . An apparatus for lubricating a non-pressurized gearbox, comprising:

a low-to-high lubricant level sensor configured to sense a static level of a lubricant within the gearbox and to display the static level of the lubricant.

2 . The apparatus of claim 1 , wherein the low-to-high lubricant level sensor is configured to send information about the static level of the lubricant to a display.

3 . The apparatus of claim 2 , wherein the low-to-high lubricant level sensor is configured to send the information electronically or mechanically.

4 . The apparatus of claim 2 , wherein the low-to-high lubricant level sensor is configured to send the information automatically.

5 . The apparatus of claim 2 , wherein the low-to-high lubricant level sensor is configured to send the information at a request of an operator.

6 . The apparatus of claim 1 , wherein the lubricant is oil.

7 . The apparatus of claim 1 , wherein the gearbox is a main rotor gearbox, an accessory gearbox, a reduction gearbox, a tail rotor gearbox or an intermediate gearbox.

8 . A method of monitoring a gearbox, comprising:

providing a low-to-high lubricant level sensor in the gearbox in fluid communication with the lubricant;

sensing a static level of the lubricant in the gearbox using the low-to-high lubricant level sensor; and

sending information from the low-to-high lubricant level sensor about the static level of the lubricant to a display.

9 . The method of claim 8 , wherein the sending information is performed electronically or mechanically.

10 . The method of claim 8 , wherein the sending information is performed automatically.

11 . The method of claim 8 , wherein the lubricant is oil.

12 . The method of claim 8 , wherein gearbox is a main rotor gearbox, a reduction gearbox, or an accessory gearbox.

13 . A rotorcraft, comprising:

a fuselage;

one or more engines coupled to the fuselage;

a gearbox coupled to the one or more engines; and

a low-to-high lubricant level sensor configured to sense a static level of a lubricant with the gearbox and to display the static level of the lubricant.

14 . The rotorcraft of claim 13 , wherein the low-to-high lubricant level sensor is configured to send information about the level of the lubricant to a display.

15 . The rotorcraft of claim 14 , wherein the low-to-high lubricant level sensor is configured to send the information electronically or mechanically.

16 . The rotorcraft of claim 14 , wherein the low-to-high lubricant level sensor is configured to send the information automatically.

17 . The rotorcraft of claim 14 , wherein the low-to-high lubricant level sensor is configured to send the information at a request of an operator.

18 . The rotorcraft of claim 13 , wherein the lubricant is oil.

19 . The rotorcraft of claim 13 , wherein the gearbox is a main rotor gearbox, an accessory gearbox, a reduction gearbox, a tail rotor gearbox or an intermediate gearbox.
