Economical excavator slewing bearing mounting base and manufacturing technology
The invention discloses an economical excavator slewing bearing mounting base and a manufacturing technology. The economical excavator slewing bearing mounting base comprises a base ring and a supporting ring; and the upper end face of the supporting ring and the lower end face of the base ring are welded together. The base ring is formed by welding three sections of arc-shaped plates end to end. The base ring is made of a low-alloy high-strength structural steel Q345D material. The supporting ring is made of a low-alloy high-strength structural steel Q345D material and is rolled into a circular ring shape through a plate rolling machine, and the circular ring connecting part is welded to form the supporting ring. The supporting ring of the slewing bearing mounting base is welded with a top plate of a middle rack. On the premise that the quality and the performance are not changed, the mounting base is optimally designed into a multi-component welding mode from a forging mode. The objective demand of excavator price drop is met to reduce cost and guarantee survival profit.
本发明公开了一种经济型挖掘机回转支承安装座及制造技术，包括座环、支撑环；所述支撑环上端面与座环下端面焊接在一起。所述座环通过三段弧形板首尾焊接而成。所述座环选用低合金高强结构钢Q345D材质。所述支撑环选用低合金高强结构钢Q345D材质，用卷板机卷制成圆环形，把圆环连接部位焊接而成。所述回转支承安装座的支撑环与中台架顶板焊接。本发明在不改变品质和性能前提下，安装座由锻造方式优化设计成多组件焊接方式。适应挖掘机价格跌落客观需求，以降低成本和保证生存利润。
