Abstract

The invention relates to a starter test stand. The starter test stand comprises a mounting flange, a clutch assembly portion, a brake portion and a flywheel portion, wherein the mounting flange, the clutch assembly portion, the brake portion and the flywheel portion are sequentially arranged on one turning shaft, the clutch assembly portion is connected with the brake portion, the brake portion is connected with the flywheel portion, one end of the turning shaft close to the clutch assembly portion is connected with an output shaft of an air starter through the mounting flange, the flywheel portion comprises a main flywheel disc, a flywheel shaft, a left balancing disc and a right balancing disc, the flywheel shaft is arranged on the turning shaft, the main flywheel disc is compacted on the flywheel shaft, the left balancing disc and the right balancing disc are connected with left and right sides of the main flywheel disc, the left balancing disc is clamped through a three-jaw or four-jaw chuck, and jaws of the chuck are uniformly distributed on circumference of the left balancing disc and can realize synchronous radial movement on the left balancing disc. The starter test stand is advantaged in that the structure is simple, operation is convenient, test on the air starter can be rapidly and conveniently realized, and load simulation under different inertia moments can be realized.

Description

technical field [0001] The invention relates to a test technology of an air starter, in particular to a flywheel test technology of an air starter. Background technique [0002] With the continuous development of my country's civil transportation industry, the number of Airbus, Boeing and other types of aircraft introduced is also increasing day by day. The turbine rotates and is transmitted to the output shaft through the reduction mechanism to provide enough torque for the main engine to start. The important role of the air starter is unquestionable. Therefore, the repair and inspection of the air starter is very important. At present, the repair and inspection of the air starter has high repair costs and long repair cycles, which seriously affect the normal operation of the aircraft. [0003] The existing patent 201020611073.1 discloses an air starter flywheel load test bench, which includes an air starter mounting flange, a flywheel clutch, a brake brake, and a flywheel ...
