Four point contact ball slewing ring are widely used in various application fields, such as excavators, cranes, rotary tables & positioners, wind turbine, ladle turret furnace, ferris wheel, water treatment, slewing drive, forest machine, medical devices, mining equipment, packaging machine, radar, satellite, robotics, transporter, solar power system, stacker, reclaimer and tunnel boring machine (TBM), etc.
Four point contact ball slewing ring application in cranes is one of important load supporting parts on a crane. It is connected with slewing table weldment of complex structure and loads. With finite element method as a tool, a model of finite element calculation is set up for Four point slewing ring of truck crane and structural strength and rigidity analysis are conducted on it.
The analysis results play an instructive role for the product development design and provide an analysis and calculation basis for the selection of high strength fastening bolts.Four point contact ball slewing ring is important part of Crane Truck.According to mechanics peculiarity,a load model is built.COSMOS/Works is used for finite element analysis of four point contact ball slewing ring the analytic result is significative in product designing.
