2. SOLAS Convention - Wikipedia

   en.wikipedia.org/wiki/SOLAS_Convention

   Initially prompted by the sinking of the Titanic, the current version of SOLAS is the 1974 version, known as SOLAS 1974, which came into force on 25 May 1980, [1] and has been amended several times. As of April 2022, SOLAS 1974 has 167 contracting states, [1] which flag about 99% of merchant ships around the world in terms of gross tonnage. [1]

3. Gear oil - Wikipedia

   en.wikipedia.org/wiki/Gear_oil

   Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with the lower viscosity hydraulic fluid, which is available at pressure within the automatic transmission. Gear oils account for about 20% of the lubricant market. [1]

4. Cross-drive steering transmission - Wikipedia

   en.wikipedia.org/wiki/Cross-drive_steering...

   A cross-drive steering transmission is a transmission, used in tracked vehicles to allow precise and energy-efficient steering. It consists of the following main parts: two identical single-stage planetary gearings, a differential, a hydraulic pump connected to the engine (similar to an oil pump of cars), a hydraulic motor powered by the ...

5. Oil record book - Wikipedia

   en.wikipedia.org/wiki/Oil_record_book

   An electronic alternative to handwritten oil record book is used on board vessels of all sizes. Marine electronic oil record books must meet the specific reporting requirements of IMO, SOLAS and flag states. Manually inserted information is normally combined with data recorded from the vessel's instruments and sensors, such as GPS data (time ...

6. Differential steering - Wikipedia

   en.wikipedia.org/wiki/Differential_steering

   Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle.

7. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

8. Gear pump - Wikipedia

   en.wikipedia.org/wiki/Gear_pump

   A gear pump uses the meshing of gears to pump fluid by displacement. [1] They are one of the most common types of pumps for hydraulic fluid power applications. The gear pump was invented around 1600 by Johannes Kepler. [2] Gear pumps are also widely used in chemical installations to pump high-viscosity fluids. There are two main variations ...

9. Tank steering systems - Wikipedia

   en.wikipedia.org/wiki/Tank_steering_systems

   The triple differential is a modification to the double differential, replacing the steering clutches with a single braked differential similar to a controlled differential. This third differential produces any desired output speed in the steering shaft, compared to the double differential where the speed of the shaft is fixed.
