Abstract

The invention discloses an over-rotating-speed rotary test bench. The test bench comprises an over-rotating-speed unit, an elevating rotation unit, a safe explosion-proof unit and an assembly test unit. The over-rotating-speed unit is installed on the elevating rotation unit. The elevating rotation unit is installed on the top face of the safe explosion-proof unit. The assembly test unit is arranged on one side, near the elevating rotation unit, of the safe explosion-proof unit. The over-rotating-speed unit is used for installing a to-be-tested piece and allowing the to-be-tested piece to be in an over-rotating-speed state. The elevating rotation unit is used for allowing the over-rotating-speed unit to be raised or descend and rotate between the safe explosion-proof unit and the assemblytest unit. The safe explosion-proof unit is used for preventing explosion when the over-rotating-speed unit is in the over-rotating-speed state. The assembly test unit is used for installing and disassembling the to-be-tested piece. According to the invention, the test bench is advantaged by compact structure, high safe coefficients and high automation degree.

Description

Technical field [0001] The invention belongs to the field of ultra-high-speed rotation testing, and specifically relates to an ultra-high-speed rotation test bench. Background technique [0002] In the field of aero engine maintenance and manufacturing, it is necessary to test the over-speed operation state of the core rotating parts. The diameter of the core rotating parts is generally 500 mm to several meters, and the test speed needs to reach tens of thousands or even hundreds of thousands of revolutions per minute to ensure The design, manufacture or maintenance of core rotating parts meets airworthiness requirements. The existing testing speed equipment is not suitable for the core rotating parts, the main reasons are: 1. It is not convenient to install the core rotating parts; 2. The safety system is low; 3. The degree of automation is not high. Summary of the invention [0003] The purpose of the present invention is to provide a super-rotating test bench suitable for core...
