新型铰轴钢支座力学性能的试验研究

设计出特殊的加载装置,对新型铰轴钢支座的滑板滑动性能及铰轴转动性能进行测试,得到了滑板滑动摩擦系数和铰轴转动摩擦系数随钢支座承载力变化规律。使用压力传感器测试聚四氟乙烯滑板的压力分布,并使用应变片测试钢支座的应力状态,试验结果表明钢支座设计符合规范要求。

Experimental Study of Mechanical Properties of New Type of Hinged Roller Steel Bearing

The special loading device was designed and used to experimentally investigate both the sliding and rolling performance of sliding plate and hinge of the new type of the hinged roller steel bearing and the laws of friction factors of the sliding of the plate and rolling of the hinge varying with bearing capacity of the bearing were obtained.The pressure load cells were then used to measure the pressure distribution of the polytetrafluoroethylene sliding plate and the stain gauges were also used to measure the stress conditions of the bearing.The results of experiment indicate that the design of the bearing accords with the codes and specifications.
