technical field [0001] The invention relates to the technical field of transmission equipment in extreme harsh environments, in particular to a non-contact transmission mechanism used in extreme non-structural environments. Background technique [0002] With the planning and implementation of a large number of missions in the fields of aviation, aerospace, deep sea, deep earth and other related science and engineering, it is urgent to solve the problem of related mission equipment under extreme conditions such as high and low temperature, high vacuum, high pressure, strong radiation and strong unknown environment. Transmission problem. In extremely unstructured environments, efficient replacement of transmission components during service can be difficult. [0003] Due to the existence of factors such as strong contact and strong constraints between the actuating module and the passive module, the current transmission device, especially the transmission device in an extreme ...

AI Technical Summary

Problems solved by technology

First of all, in extreme environments such as high vacuum, it is difficult to achieve effective lubrication of the oxide film, resulting in cold welding

Second, strong radiation (such as space environment, nuclear power environment) will cause the erosion of atomic oxygen, making it difficult to effectively connect the active module and the passive module

Third, the high and low temperature environment will lead to strong thermal expansion and contraction of mechanical parts, which will reduce the mechanical properties

Fourth, the strong unknown environment makes it difficult to achieve on-site operation by humans. For tasks that require frequent multiple multi-angle actions and high-precision docking with passive modules to achieve effective transmission, teleoperation or autonomous operation robots may become a major task. However, there are often problems such as system complexity and large demand for perceived information, which greatly reduces the cost-effectiveness of task execution

[0004] Based on the electromagnetic transmission is an effective solution, it has non-contact characteristics, but the current electromagnetic transmission is mainly limited to the technical field related to the disc motor, which mainly realizes the change of the magnetic field by rotating the permanent magnet to complete the performance transfer of the drive components, but In extreme non-structural environments, the relative distance between the actuator module and the passive module is relatively large, which cannot meet the requirements
