Elevator system for vacuum heat test environment

Abstract

The invention discloses an elevator system of a vacuum heat test environment. The elevator system of the vacuum heat test environment comprises a power system, a transmission system, a heat control system and a control system, wherein the power system, the transmission system and the heat control system are arranged in a space environment simulator, and the control system is arranged outside the space environment simulator. The power system adopts a three-phase hybrid stepping motor, and carries out transformation on the lubricating mode of the three-phase hybrid stepping motor. The transmission system comprises a worm gear reducer, a steel wire rope reel, a pulley device, a tensioner and lifting appliances, wherein the pulley device, the tensioner and the lifting appliances are designed for meeting system reliability. The heat control system mainly controls the work temperature of other components in the space environment simulator to meet requirements. The control system mainly achieves concentrated operating and controlling on the whole system. Compared with the prior art, the elevator system of the vacuum heat test environment achieves rising and falling of an infrared heating cage and other tools in a test working condition period, and overcomes the influences of high vacuum and ultralow temperature environment, and the shifting of the tools is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing in a vacuum heat test environment, and in particular relates to a driving system for realizing vertical lifting of tooling in a space vehicle vacuum heat test environment. Background technique [0002] Vacuum thermal test is an indispensable test item in the process of spacecraft development. The test is generally completed in a space environment simulator. The space environment simulator provides a vacuum and cool black background for simulating space. With the development of vacuum thermal test, realistic According to the model, it is necessary to develop a drive system to realize that the tooling can move in the space environment simulator during the test conditions. Although similar driving systems are very common in ordinary environments, there are various options for both the power system and the transmission system, but considering the high vacuum (less than 1×10 － 4 Pa),...

Problems solved by technology

Although similar driving systems are very common in ordinary environments, there are various options for both the power system and the transmission system, but considering the high vacuum (less than 1×10 － 4 Pa), ultra-low temperature (lower than -190°C) environmental impact will be greatly restricted in the selection of system solutions, and many technical problems such as structural strain, vacuum lubrication, and motor thermal control need to be overcome
