Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a dual-channel bearing lubrication structure with both under-ring lubrication and top-ring lubrication in order to overcome the disadvantages of poor lubrication effect of the existing bearing ring lubrication structure, and the two-way lubrication structure is independent running without interfering with each other, which well solves the technical problem of high heat generation of bearings under high-speed and heavy-load conditions

Abstract

The invention provides a novel bearing lubricating structure. The novel bearing lubricating structure comprises an upper annular lubrication part and a lower annular lubrication part; the upper annular lubrication part mainly enables lubrication oil to be sprayed on a rolling element through an oil path of a casing and an end cover so as to lubricate a bearing. The lower annular lubrication part mainly stores oil through an oil storage structure of an inner cavity of a rotary shaft, and then the lubrication oil enters an inner bearing ring and a retainer through four rows of annular oil holes in the rotary shaft to lubricate the bearing. The double-channel bearing lubrication mode of the upper annular lubrication part and the lower annular lubrication part is adopted, so that the bearing lubrication effect is good, and the technical problem of a large bearing heating amount under the high-speed heavy-load condition is solved well. The novel bearing lubricating structure is novel; the lubrication effect is good; the two paths of lubrication modes do not interfere with each other and operate independently; reliability of bearing lubrication is improved; at the same time, the heating amount of a bearing is reduced and the service life of the bearing is prolonged by increasing the lubrication amount of lubrication oil.

Description

technical field [0001] The present invention relates to a lubricating structure, more specifically, to a novel bearing lubricating structure. Background technique [0002] Bearing is a key component in the helicopter transmission system, its performance directly affects the service life and reliability of the helicopter transmission system, and a well-designed lubrication system is the most important measure to improve the service life and reliability of the bearing. The input end of the main reducer has high speed and high power, and has extremely high requirements on the lubrication of the bearings. Therefore, it is imperative to design an excellent bearing lubrication structure. At present, the bearing lubrication method of under-ring lubrication is mainly used. The main disadvantages of the under-ring bearing lubrication method are: under the condition of high speed and heavy load, the bearing lubrication effect is not good, and when the bearing size is larger, the bea...
