introduction:What oil is added to the planetary cycloidal pinwheel reducer? If it comes from the factory,Its usually grease,Molybdenum disulfide is used-2orZL-2Lithium base grease and other grease。Because the reducer at the factory is for easy loading and unloading and transportation.Usually no lubricating oil is injected,Oil is only injected before use,Recommended at room temperatureN150Extreme pressure industrial gear oil。Lubricating oil change cycle:The reducer is in its first run200The first lubricating oil change must be carried out after hours,When replacing, there should be no residual oil。After the initial oil change,Work continuously every daylOMore than hours of speed reducer.Should be every other3Change the lubricating oil once every month、everyday
