Bearing support device for aero-engine

Abstract

The invention discloses a bearing supporting device applied to an aero-engine. The bearing supporting device comprises a bearing; the bearing comprises an inner ring body; a plurality of balls are installed at the outer wall of the inner ring body; a clamping plate is installed in an inner chamber of a clamping slot; an inserting rod is installed at the upper surface of the clamping plate; the topend of the inserting rod is connected with a second upright post; and a second spring is installed at the bottom of the clamping plate and is connected with the inner wall of the clamping slot. According to the bearing supporting device applied to the aero-engine, a first clamping ring and a second clamping ring are used for clamping the bearing at the middle; a nut is tightened and the clampingplate is pressed tightly in a way of twisting a bolt so that the bearing can be clamped by the first clamping ring and the second clamping ring; when shock occurs, the first spring supports the secondupright post so that the shock is alleviated, and the clamping plate is used for limiting the relative positions of a first upright post and the second upright post; and the second spring positionedat the bottom of the clamping plate can also be used for reducing an impact force when shock occurs, so the safety of people is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing support device for an aero-engine. Background technique [0002] In modern industrial production and daily life, bearings can be seen everywhere, and as a fixing device for bearings, bearing supports have been widely used, such as the invention patent application number CN 203130990U, including transmission shafts, bearings, bearing supports Although the structure of the invention patent is simple, it cannot effectively absorb shock, which makes the rotating shaft of the engine vulnerable during the aviation process, which not only brings inconvenience to people's travel but also brings security risks. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a bearing support device for an aero-engine to solve the above-mentioned problems in the background art. [0004] In order to achieve the above purpose, the present invention provides...
