    The specific effects of thermal expansion and contraction factors on the clearance of ZSC600-77.5-3 medium hard tooth reducer are as follows: The impact of temperature rise Reduced gear clearance: During the operation of the reducer, components such as gears generate heat due to friction, leading to an increase in temperature and expansion of metal materials. If the original gear mesh cleara

    In addition to stress relief annealing, the following methods can also be used to reduce the stress on the gearbox housing: Vibration aging method: By using specialized equipment to induce resonance in the box under periodic external forces, the internal microstructure of the box undergoes grain slip and twinning, thereby reducing residual stress peaks and improving stress distribution. This me

    To solve the problem of poor assembly accuracy of ZDY355-3.15-1 hard tooth surface gear reducer, the following aspects can be taken into account: Precision control of parts processing Box processing: The assembly reference surface of the box should have high flatness and small surface roughness. When processing, first process a larger plane as the positioning base for hole processing, and se

    The main reasons for abnormal vibration during the trial operation of large hard tooth surface reducers after maintenance are as follows: Gear problem Abnormal meshing: When there is pitting, peeling or tooth profile error on the contact surface of the gear pair, the contact area of the tooth surface will shift, resulting in periodic impact loads and vibration. In addition, gear eccentricity
