It adopts hard tooth surface hellcal gear reductionwidened tooth surfaceincreased moduluslarge meshing degree and enhanced load carrying capacity,which is 3-5 times of the life of conventional reducer. he gearbox gear is machined by German NILES gear grinding machineThe transmission is stablethe noise is small,the service life is long,and it can withstand high power and heavyload he gearbox lubricating oil adopts independent water cooling system device to reduce oil temperature and increase the service life of internalbearings. The spindle bearing is lubricated by the reducers own thin oilwhich can achieve the lubrication effect and reduce the spindle bearing temperature. Pressure roller bearing adopts independent automatic oil filling system,regular oil injectinggood stability and long service life..syi
