It has the function of rendezvous and docking with Tian Gong two space laboratory, implementing propellant in orbit and adding, carrying out space science experiment and technical test, which is called "space express man". The successful launch of Tian Zhou I is the "ending battle" of our space laboratory, marking the opening of the space station in China.

 

In the bearing products provided by the enterprise, the ground part includes the radar bearing of the measurement and control station, the bearing of the launching frame, the spaceship part including the solar panel bearing, the harmonic transmission transmission bearing, and the special condition of the special working condition of the intersection of the Tian Gong No. two and the Tian Gong No. 1.

 

In order to make the "Tian Zhou Hao" more transported, the lightweight parts of the spacecraft were designed. Among them, the axle shaft uses the bearing integration technology, and innovatively develops several non standardized bearings under special conditions. The integrated design of the bearing and the related parts outside the bearing realizes the multi function combination of transmission, support and rotation, which reduces the weight of the related organizations, and helps the No.1 boat to play the array and carry more.

 

There are also harmonic reducer bearings for lightening the spacecraft. Qu Qiong introduced that in order to minimize the weight in the limited space, the harmonic reducer bearing is designed light, the thinnest ring wall thickness less than 1 millimeters, the vertical position on the plane may be due to self weight and deformation, processing difficulty can be seen. In addition to the sky boat 1, most of the harmonic decelerator bearings came from the axis of the Shenzhou series spacecraft, the Tiangong space laboratory and the Chang'e series satellite.

 

The product is not only lighter, but also more accurate. Under the lightweight design of Tian Zhou No.1, the transmission power is very small in the link with the Tian Gong two rendezvous and docking and other links. It is necessary to use the force of "Dragonfly water" to realize precision driving and positioning, which can not be separated from the high rotation precision of the bearing of the enterprise harmonic transmission transmission.

 

The surface quality of the bearing ring is not more than 5/10000 mm, and the production task is successfully completed with the highest precision level of the international standard, which greatly reduces the influence on the force transmission and realizes the lower friction. Torque.

 

As the record holder of the highest bearing precision, the most complex structure and the largest shape and size, the Luo shaft has the only National Key Laboratory for Aviation Precision Bearing in the whole industry, and has been set up for many times for the Shenzhou series, the Tian Gong series space laboratory and the Chang'e series satellite production series. Bearing shows the strong strength of aerospace bearing technology research and development.
