AI Technical Summary
In the existing technology, the balance bushing is fixed inside the support body by welding, which makes disassembly and replacement extremely complicated and difficult, and it is prone to wear or aging after long-term use.
It adopts quick-release and lubrication components, including positioning pins, connectors, bolts, oil inlet funnels, etc., to achieve convenient installation and disassembly of the balance bushing, and ensures accurate injection of lubricating oil through the oil inlet funnel and oil inlet pipe.
This design achieves stability and convenient positioning stability for the balance bushing. Simultaneously, the structural design allows for easy disassembly and replacement of the balance bushing components, solving the stability and convenience issues of the balance bushing. It also improves installation efficiency, simplifies maintenance, saves time and labor, and addresses the stability and convenience limitations of existing balance bushing technologies. Furthermore, it improves lubrication, ensures optimal lubrication, and reduces maintenance costs.
