Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the embodiments of the drawings.

[0011] figure 1 As shown, the multi-purpose wheel tester includes 1-motor, 2-coupling, 3-gear box, 4-intake volute, 5-test chamber, 6-test wheel, 7-support shaft, 8 -Exhaust volute. 1-The motor is connected to the 3-gear box through the 2-coupling, the 3-gear box is connected to the 7-support shaft, the 4-inlet volute is located between the 2-gear box and the 5-test chamber, and the 6-test wheel The disc is located in the 5-test chamber, and the 8-exhaust volute is located behind the 5-test chamber. 6-The test wheel is made of high temperature resistant titanium alloy.

[0012] Operation mode: Driven by 1-motor 2-gear box, transfer the required speed to test 7-support shaft and 6-test wheel, the gas enters 5-test chamber through 4-inlet volute, and the load (pressure , Temperature) is transferred to the 6-test wheel, the gas is finally discharged through...

Abstract

Provided in the invention is a multipurpose wheel disc tester comprising a motor, a coupler, a gear box, an air inlet volute, a test cabin, a test wheel disc, a supporting shaft and an exhaust volute.The motor is connected with the gearbox through the gear box, the gearbox is connected with the supporting shaft, the air inlet volute is arranged between the gearbox and the test cabin, the test wheel disc is arranged in the test cabin, and the exhaust volute is arranged behind the test cabin. The gearbox is dragged through the motor, the required rotating speed is transmitted to the supportingshaft and the test wheel disc, gas enters the test cabin through the air inlet volute, loads (pressure and temperature) are transmitted to the test wheel disc, and the gas is finally exhausted throughthe exhaust volute, so that the test cabin has the functions of heat preservation and vacuumizing. The invention provides a multipurpose wheel disc tester to realize the traditional fatigue test anddamage test as well as the thermal shock and load test.

Description

Technical field [0001] The invention relates to the technical field of aero-engine compressor and turbine wheel disk testing, and is a multi-purpose wheel disk tester. Background technique [0002] The working environment of aero-engine compressors and turbines is harsh, and they bear high pressure, high temperature, impact and other loads. The early strength test is an indispensable part of the aero-engine development process. The current roulette tester can complete fatigue, damage and other tests, and does not have a comprehensive working environment that simulates roulette. The development of a tester with comprehensive environmental simulation can provide important support for roulette research. Summary of the invention [0003] The purpose of the present invention is to provide a multi-purpose roulette tester, which can meet various tests of roulette, including fatigue test, destruction test, load test, thermal shock test, high temperature and low temperature test, etc. [0...
