introduction：Size limitation。usualINAbearing[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。]The space that can be installed is limited。In most cases，Shaft diameter(Or bearing bore diameter)Is based on mechanical design or other design limitations。Therefore, the choice of bearing type and size is determined by the inner diameter of the universal joint bearing。therefrom，Dimension axis

introduction：After mold installation and debugging，Can normally produce qualified workpiece，This process is called die service。 In general，We always want molds to last long enough Time limit，To meet the actual needs of production。 However, the mold may have some defects during the manufacturing process，Or some defect gradually developed in the course of service，microcrack、Light wear、Deformation and so on，In this case, although the mold has hidden dangers, it can continue to work，This state, which has defects but does not lose the ability to serve, is called mold damage。 The mold is damaged for some reason，Or mold damage accumulated to a certain extent resulting in mold

introduction：Failure forms of worm drive and gear drive（Gear reducer）likeness，There is also pitting on the tooth surface、wear、Gluing and breaking of worm gear teeth and other forms。Among them, the pitting corrosion and wear of wormwheel tooth surface are the most common，Gluing also occurs。The above failure occurred，The main reason is that the relative sliding speed between the meshing tooth surfaces is large，Especially in cylindrical worm drive lubrication Angle8Too small，Cant form a dynamic oil film，Caused by low gnawing efficiency and high temperature rise。In addition, due to the insufficient stiffness of worm or manufacturing and installation errors and other factors will also lead to the occurrence of the above failure forms。The fracture of worm gear teeth is mostly due to the wear of the gear teeth
