  How to optimize the heat treatment effect of ZLY12

  25-07-25

  To optimize the heat treatment effect of ZLY125-12.5-1 gear reducer, we can start from the following aspects: Material selection and control Selecting appropriate steel: Steel mills are required to provide "low and stable deformation" steel, control the hardenability zone of the steel to be as narrow as possible, to ensure stable deformation during heat treatment. Meanwhile, controlling the

  What are the specific effects of thermal expansion

  25-07-24

  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

  What could be the reasons for abnormal vibrations

  25-07-22

  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
