The invention discloses a transmission shaft with torque and turn angle measurement functions for a thermal vacuum environment and relates to the field of testing devices of lower shafts in thermal vacuum experiments. The transmission shaft comprises a transmission shaft part, two air floatation sleeves, a non-magnetic seat and a magnetic core assembly, wherein the transmission shaft part is sequentially sleeved with the magnetic core assembly, the first air floatation sleeve and the second air floatation sleeve from left to right, and a torque measurement component is mounted on the transmission shaft part and positioned in a clearance between the first air floatation sleeve and the second air floatation sleeve. According to the transmission shaft, the magnetic core assembly exerts a sealing effect; the two air floatation sleeves form a stable air film on the transmission shaft to form air floatation support for the transmission shaft; the bending of the transmission shaft is avoided; since air floatation devices have the advantage of no friction, the influence of friction of a bearing on torque measurement is avoided; the testing accuracy is improved; exhaust vents are axially and uniformly distributed in the two annular end faces, close to an electric brush seat, of the first air floatation sleeve and the second air floatation sleeve; a stable air film is formed between the two air floatation sleeves and the electric brush seat; and the influence of relative friction due to direct contact between the electric brush seat and the air floatation sleeves on the measurement accuracy is avoided.
Description
technical field [0001] The invention relates to an angle testing device of a shaft under a thermal vacuum experiment, in particular to a transmission shaft with torque rotation angle measurement in a thermal vacuum environment. Background technique [0002] Thermal vacuum test refers to the test to verify the performance and function of the tested part under the specified vacuum and thermal cycle conditions. The thermal vacuum test not only requires a vacuum simulation system capable of simulating the vacuum environment of outer space, but also requires a device that can drive or load the equipment to simulate the drive and load of the mechanism, as well as real-time high-precision measurement of the torque, Capability of information such as rotation angle and rotational speed. [0003] In the thermal vacuum test of torsional loading on the tested part, due to the thermal vacuum environment, the reliability of sensors and power equipment is reduced, the service life is shor...
