AI Technical Summary

Technical Problem

In the existing lubrication system of the deceleration device of aircraft turbine engine, the oil spray and the impact between the oil in the tank cause splashing, resulting in insufficient filling of the bag, affecting the continuity and uniformity of lubrication, and limiting the amount of oil and lubrication efficiency of the parts to be lubricated.

Method used

Design a wheel including an oil stabilizing groove and an oil distributing groove, the stabilizing groove and the distributing groove being separated by a common radial wall, the stabilizing groove receiving oil supplied by an injector and supplying it to the distributing groove via overflow, the distributing groove being connected to different lubrication circuits to ensure maximum oil level and continuous supply.

Benefits of technology

The design of the stabilizing groove reduces splashing, ensures maximum oil level and continuous lubrication in the distribution groove, and improves the efficiency and service life of the deceleration device.
