Tool and method for measuring starting torque in self-lubricating semi-ring loading state

The invention relates to the technical field of torque measurement, in particular to a starting torque measurement tool and method in a self-lubricating semi-ring loading state. The invention provides a starting torque measuring tool in a self-lubricating semi-ring loading state. The starting torque measuring tool comprises a loading device, a starting torque measuring device and a dovetail groove sliding rail. According to the measuring method, the torque of the self-lubricating semi-ring in a bearing state is measured, the working state of the semi-ring can be truly restored, a high-precision sensor is adopted, and the precision and efficiency of the measured starting torque are guaranteed on the premise that the operation complexity is not increased. 本发明涉及力矩测量技术领域，具体涉及一种自润滑半环加载状态下启动力矩测量工装及测量方法。本发明提供一种自润滑半环加载状态下启动力矩测量工装包括：加载装置、启动转矩测量装置和燕尾槽滑轨。所述测量方法是承载状态下的自润滑半环的力矩测量，可真实还原半环的工作状态，且采用高精度传感器，在不增加操作复杂性前提下，保证所测启动力矩的精度及效率。
