OIL FILTER AND METHOD OF INCREASING SERVICE LIFE OF OIL FILTER

摘要

A method of increasing service life of an oil and a filter in a transmission which converts a variable speed input into a constant speed output for driving a generator producing constant frequency power in an airframe in accordance with the invention utilizes a filter having interstices wetted prior to placement in an oil circuit with a quantity of a liquid additive that is washed from the interstices of the filter into solution with the oil during filling and/or operation of the transmission to form a mixture of the oil and additive which reduces the formation of metallo-organic soaps and solids, that are retained in the interstices of the filter. The filter may have pleats (63) having a plurality of layers including the filter media (46). One of the layers of the filtering media may be coated with an additional layer or surface coating (80) disposed on the pleats which is wettable by the additive.
