introduction：Worm bearing of worm gear reducer[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Cause of damage： When the worm gear reducer fails，Even if the gearbox is well sealed，It is often found that the gear oil in the worm gear reducer has been emulsified，Bearing rusted、corrosion、breakdown，This is because the worm gear reducer is in the process of shutdown，Gear oil changes from hot to cold
