Embodiment Construction
[0022] The central transmission device is the main transmission device for jet engine power extraction. It is usually installed on the front journal of the compressor. It has the characteristics of large transmission power, high rotation speed and large impact load. The meshing clearance value of the central transmission bevel gear is unreasonable or Poor meshing marks will directly lead to incorrect meshing of bevel gears, which will damage or break the teeth when the engine is started or in working condition.
[0023] At present, in the practice of aero-engine assembly, the coloring inspection of spiral bevel gears is the only way to ensure that the tooth surface contact impressions of the gear pair under rated load are symmetrically distributed along the pitch line along the entire length of the tooth width. The central transmission bevel gear meshing clearance inspection device generally has engineering problems such as complex structure, poor repeatability, and inaccurate ...
