Lanzhou slewing bearing 3... specialty store/ ' (3,3,3) - Whether the slewing bearing is working properly or not directly affects the production of the integrated machine and even the entire operation line, and is directly related to the safety of personnel and equipment. , is a critical part of the material transport machinery system, and there is an urgent need to implement status monitoring and diagnosis. However, there is currently relatively little work in this area at home and abroad, and it is technically difficult to perform condition monitoring and diagnosis on Dalech.
/ ' (3,3,3) - Inside the outer ring of the slewing bearing The ring is an elastic body that contacts the rolling elements at multiple points and is connected to large metal structural parts, so changes in its stiffness have a great impact on the force distribution. As a result, the stiffness and force conditions of the slewing bearing are very complex, which is the most likely location for failure, and the mechanism is complex and difficult to diagnose.
/ ' (3,3,3) - Since the slewing bearing adopts a fully enclosed structure, the internal operation conditions of the slewing bearing are not closely monitored, and there have been cases of unnecessary downtime and repairs due to misjudgment. , wasting manpower and material resources and losing production time.
/ ' (3,3,3) - For such a large slewing bearing installation, there are no mature monitoring and diagnosis methods at home and abroad that can be used for reference, and there are no factory standards for the communication of working conditions. All work must be done from scratch.
/ ' (3,3,3) -However, once the slewing bearing fails, the maintenance work will be very complicated, and the slewing bearing must be turned on and off with hundreds of tons of weight. The machine room and skeleton system must be lifted to a certain height before they can be dismantled and inspected. In this way, the only floating crane in Shanghai must be used for hoisting, and the one-time process fee is _) million yuan. If the raceway is defective, it is necessary to dismantle it and send it to a repair truck for repair. Due to the complicated repair process, according to statistics, the door closing machine must be shut down at least once for overhaul. In the past few months, the economy has suffered huge losses. Therefore, Tanche requires the implementation of the state
