1.回转机构组成及工作原理(1)组成液压挖掘机回转机构主要由回转支承、回转减速器、回转制动器和回转液压系统等组成。回转支承回转支承如同大型滚动轴承,其外圈用螺栓与转台连接,内圈用螺栓与底盘连接,内、外圈之间设有滚动体。挖掘机工作装置作用在转台上的垂直载荷、水平载荷和倾覆力矩均通过转台、回转支承的外圈、滚动体和内圈传递给
1. Slewing mechanism composition and working principle (1) Composition Hydraulic excavator slewing mechanism is mainly composed of slewing bearing, slewing reducer, rotary brake and rotary hydraulic system. Slewing Bearing Slewing Bearing Like a large roller bearing, the outer ring is bolted to the turntable, the inner ring is bolted to the chassis, and the rolling elements are provided between the inner and outer rings. Excavator working device acting on the turntable’s vertical load, horizontal load and overturning moment through the turntable, slewing ring, outer ring, the rolling body and the inner ring passed
