At 14:22 on July 24th, the second cabin section of China Space Station — asked the Tianjin Experimental Crystal at the Wenchang Aerospace launcher in Hainan, and the vast sky ushered in the first scientific experimental cabin in China. The wisdom of the Chinese scientists' team's wisdom is involved, and there is also the credit of Chongqing scientists!

The cover news learned from Chongqing University that the R & D work of the Alpha institutions of the Sky Experimental Cel's "Constructing Gear Transmission" was the team of Professor Chen Bingkui, the National Key Laboratory of the National National State, and overcome a number of key technologies for 8 years and finally completed the delivery of delivery. Essence

According to reports, after the Sky Experimental Curm completed the posture adjustment and system debugging on the scheduled track, the Alpha of the solar cell wing of the solar cell wing will be put into use.

The "pair gear transmission" adopted by Alpha institutions is the new type of gear transmission proposed by Professor Chen Bingkui. This gear transmission has outstanding error adaptability and high bearing capacity, which can meet the alternating changes in extreme height temperatures of space, and put forward strict requirements for Alpha institutions, including large space size changes, high reliability, long life, etc.

During the 8 -year R & D process, Professor Chen Bingkui's team accumulated the theoretical research and industrial application in the early stage, and overcome many key technologies of "confrontation gear". Digital closed -loop precision processing and measurement under the action of multiple physical quantities, and accelerated fatigue life test technology and equipment under the integrated conditions.

In the end, the team of Professor Chen Bingkui was reluctant to complete the research and development of gear -constructive products in the experimental compartment Alpha institution, and under the cooperation of Shanghai Aerospace System Engineering Research Institute, Shanghai Aerospace Equipment General Plant, Zhengzhou Institute of Mechanical Research Institute and other units , Complete the delivery of a righteous product of the gear.
