Abstract

The invention provides a tester for performing heating and loading fatigue examinations on an engine sealing fin. The tester is formed by a temperature control device (1), a supporting plate (2), a transmission shaft (5), a cam (8), a gear (9), a motor (10), an upper cover (11), a heating device (15) and a supporting shaft (13), wherein the temperature control device (1), the motor (10) and the upper cover (11) are distributed on the supporting plate (2); the motor (10) and the cam (8) are connected with each other through the gear (9); the transmission shaft (5) is distributed at the upper part of the supporting plate (2) in the tester for performing the heating and loading fatigue examinations, and the cam (8) is distributed on the transmission shaft (5); and the supporting shaft (13) is distributed below the sealing fin (14) and is far away from the lower side of the upper cover (11) to be contacted with the sealing fin (14). The tester disclosed by the invention is applied to a test for examining the fatigue strength reliability of the sealing fin which is welded, fills an industrial blank and has great economic and social values.

Description

technical field [0001] The invention relates to the structural design and application technical field of a heating and loading fatigue test device for a sealing sheet of an engine afterburning cylinder, and in particular provides a tester for heating and loading fatigue testing of an engine sealing sheet. Background technique [0002] An engine afterburner cylinder seal is one of the key and important parts used in the engine, and it is mainly used in the engine afterburner cylinder. It is a part subjected to high temperature, high load, large air flow, and high vibration. Therefore, after working for a period of life, some cracks are produced on the middle edge of some sealing sheets. According to the manufacturer's regulations, the sealing sheet must be replaced after cracks appear, and the sealing sheet is often scrapped due to cracks. Since the afterburner cylinder seal is a high-temperature component, it has high requirements in terms of material and structure, and is...
