The Influence Caused by each Assembly Misalignment on the HGT Hypoid Gear's Meshing Performance

Article Preview

Abstract:

The assembly misalignment is the key factor that influences the meshing performance of gear, the meshing performance worked on no-load or light load conditions is more completely expressed by contact pattern and transmission error. According to the contact pattern and transmission error, the influence of assembly misalignment to the meshing performance of hypoid gear is studied, this method break the limitations relying on experience to adjust the installation. Based on the machining principle and method of Gleason hypoid gears which machined by the HGT method, the mathematical model of machining was established, and the theoretical tooth surface equations were derived, on this basis, the hypoid gear as an example, the tooth contact analysis (TCA) was carried out considering assembly misalignment, the conclusion was drew that the influence to the position of tooth surface contact area and the magnitude of transmission errors are different when the Assembly misalignment affecting alone. This can offer certain reference for the installation and adjustment of hypoid gear pair in engineering practice.
