introduction：Everyone in the reducer industry knows that，The noise of the reducer, especially the worm gear reducer, is a headache for many reducer manufacturers。Reducing noise and ensuring stability during operation are the primary conditions for the quality of the reducer。 For how to achieve this goal，Many scholars at home and abroad regard the change of tooth meshing stiffness in gear transmission as gear dynamic load、Vibration and noise are major factors。By modifying the shape，The dynamic load and velocity fluctuation are minimized，To achieve the purpose of reducing noise。This method has proved to be a more effective method in practice。But in this way，There is a technical need

introduction： The external magnetic field is used to drive the arc to rotate and heat along the workpiece﹐The method by which the workpiece is then welded by forging(See picture Rotating arc welding diagram )。Rotary arc welding is mainly used for welding pipe fittings﹐Place the tube to be welded in a magnetic field during welding﹐Power is applied after clamping with electrodes﹐The interaction of a radial magnetic field and a current generated by an exciting coil﹐The arc is rotated around the circumference of the tube wall。Uniformly heating the tube end produces a thin layer of molten metal﹐And then quickly pressurize﹐Extrusion molten metal﹐A welded joint is formed。Rotary arc welding is1959Soviet research success﹐But do this welding
