Electric power closed type double-input accessory transmission system test bed

Abstract

The invention provides an electric power closed type double-input accessory transmission system test bed. The test bed comprises a main driving motor 1, an auxiliary driving motor 10, a main step-up gear box 2, an auxiliary step-up gear box 11, an axial force loading device 3, a load end loading motor II5, a load end loading motor I6, a load end loading motor III7, a reduction gear box I8, a reduction gear box II9, a central transmission mounting box 12, a transmission rod 13, a central transmission gear box 14 and a main motor coupler 15. The device comprises an auxiliary motor coupler 26, a main input coupler 16, an auxiliary input coupler 27, a load coupler I 17, a load coupler II 21, a load coupler III 22, a load reducing sleeve I 19, a load reducing sleeve II 24, a load reducing sleeve III 25, a load end torquemeter I 18, a load end torquemeter II 20, a load end torquemeter III 23 and an input end torquemeter 28.

Description

technical field [0001] The application relates to the mechanical field, in particular to a test bench for an electric power enclosed double-input accessory transmission system. Background technique [0002] In the construction of the existing transmission system test benches of the aircraft and engine attachments, the hydraulic loading method is often used to load the load end of the accessory transmission system. Usually, the loading method is open-loop control. After years of tests, it has been found that the The control accuracy is low, and there is a large torque pulsation during the loading process. At the same time, the loading system is bulky, and a large oil mist will be generated during the heating process, and there is a risk of system oil leakage during use. While a large amount of energy is lost, it also greatly increases the workload of daily maintenance of the system.
