Abstract

The invention provides a lubricating oil nozzle with a filtering function. The lubricating oil nozzle with the filtering function comprises a nozzle shell, a nozzle, a spring and a filter screen, wherein the nozzle is at least partially arranged in the nozzle shell, one end of the nozzle is a spray hole, the other end of the nozzle is provided with a plurality of filter holes formed in the radialdirection, and the filter holes communicate with the nozzle; the spring is arranged between the nozzle shell and the nozzle; and the filter screen covers the filter holes, and lubricating oil flowinginto the spray hole is filtered through the filter screen. According to the lubricating oil nozzle with the filtering function, simple filtering before injection can be achieved, foreign matters possibly blocking the nozzle are intercepted, the requirements on the lubricating oil injection speed and flow are effectively met, and safe work of an engine is guaranteed.

Description

technical field [0001] The application belongs to the technical field of nozzles, in particular to a lubricating oil nozzle with a filtering function. Background technique [0002] Lubricating oil nozzle is the most basic component in the lubricating oil system of aero-engine and gas turbine. The lubricating oil nozzle directly provides lubricating and cooling lubricating oil for each fulcrum bearing, gear tooth surface and sealing device. In order to make the lubricating oil pass through the rotating gap (such as the gap of the bearing, etc.), the lubricating oil nozzle should not only ensure that the installation is correct, so that the lubricating oil can be sprayed to the required position, but also provide sufficient injection speed. In order to take into account the injection speed and prevent nozzle hole clogging, the nozzle hole diameter is generally between 0.6mm and 1.2mm. When a large flow rate is required, multiple nozzle holes are often used to ensure the flow r...
