Bucket wheel stacker reclaimer rotary support using manual lubrication, each shift to the slewing bearing injection hypoid gear oil. Due to the low hyperbolic gear oil viscosity, slewing ring is not easy to store oil, so dust easily invaded the slewing ring. Sediment deposited in the raceway dust can not be cleaned, resulting in blocked oiling pipe, roller stuck in the raceway. To clean up the machine must be demolished before the operation, the cost of about 100,000 yuan, and delayed delays, affecting production. I developed the demolition of clean-up technology, both to save money and manpower, but also does not affect the production.
The temporary addition of auxiliary equipment is used to inject the high-pressure descaling solution into the slewing bearing. Through the bucket wheel stacker-retrieving machine, the slewing ring is repeatedly rotated to make the relative movement between the slewing bearing friction pairs clear and the grease and dust deposited on the raceway clean. Clean up and then injected into the slewing bearing oil, the descaling liquid clean. Clean the rotary support ring groove set to clean up the waste oil for recycling, to avoid environmental pollution. After cleaning, the auxiliary equipment will be removed, replaced by manual dry pump, restore the original machine lubrication system. Using manual dry oil pump, lithium-based grease is injected into the slewing bearing for lubrication. It is recommended to clean every 500 working hours, each cleaning costs about 2000 yuan, annual savings of 150,000 yuan.
