AI Technical Summary

⚠Technical Problem

Traditional marine gearbox lubrication systems reduce high-pressure oil to low pressure via a pressure regulating valve when supplying oil to wet friction clutches. This results in significant power loss, reduced gearbox transmission efficiency, and increased lubricant temperature and cooling water energy consumption.

⚗Method used

The friction clutch control device, which uses branch-circuit lubricating oil booster drive, forms a booster assembly by adding components such as a working oil pump, hydraulic motor, first throttle valve, and working oil safety valve. It uses only a small amount of low-pressure lubricating oil to boost the working oil, thereby reducing power loss and improving gearbox transmission efficiency.

🎯Benefits of technology

It reduces power loss, improves gearbox transmission efficiency, reduces cooling water consumption, and meets the weight and efficiency requirements for marine applications.

Abstract

The application relates to a branch lubricating oil pressure boosting driven friction clutch control device, and relates to the field of a marine transmission gear box and a friction clutch control device thereof. The friction clutch control device of the traditional lubricating system of the marine gear box solves the problem that when oil is supplied to a wet friction clutch, the large-flow oil pumped by the oil pump of the gear box shaft passes through a pressure regulating valve and is changed from high pressure to low pressure, power loss is large, and the transmission efficiency of the gear box is low. The friction clutch control device is increased with a working oil pump, a hydraulic motor, a first throttle valve and a working oil safety valve, wherein the combination of the hydraulic motor and the working oil pump becomes a combined hydraulic element which can be pressurized, only a small amount of low-pressure lubricating oil is used to become working oil after being pressurized, the rest of the large amount of lubricating oil does not pass through the pressure regulating valve, power loss is reduced, and the transmission efficiency of the gear box is improved. The application mainly controls the oil supply and discharge process of the friction clutch.
