Description

technical field [0001] The invention relates to the field of precision instrument testing, in particular to an accurate measurement device for conductive slip ring friction torque. Background technique [0002] Conductive slip rings are widely used in the fields of aerospace, aviation, navigation and various precision instruments to realize the transmission of electrical power or electrical signals between two relatively rotating parts, and to avoid twisting the wires during relative rotation. The basic requirements of conductive slip rings are insulation performance, contact resistance change rate, reliability, environmental adaptability, and service life. The friction torque of the conductive slip ring has a significant impact on the noise and life of the conductive slip ring. It is an important index to measure the conductive slip ring, and it also affects the power and control accuracy of the conductive slip ring application system. [0003] At present, the measurement ...

Problems solved by technology

However, the data measured by repeated tests using this test method are quite different, and the data measured by different people are also different. The main reason for this difference is that each time the conductive slip ring rotor is moved by the force gauge Different speeds, different dialing directions, hand shake and other factors, so this test method is highly subjective and cannot be used as a scientific test method

And the leading wire of the 96-ring conductive slip ring is as long as 1m, which is easy to be dragged to the ground or on the table during the friction torque test to affect the test results
