Air-bearing is a core component of air-bearing rotary stage. The weakness that the air-bearing has the low load capacity and stiffness has been concerned about by domestic and foreign scholars. So how to improve the load capacity and stiffness has become a serious problem. In order to improve the load capacity and stiffness of the air-bearing rotary stage
in this paper
we improved structure of Zhang Wenjie and others' high-precision direct-drive air-bearing rotary stage. The gas film of air-bearing has been meshed by GAMBIT software
and we use FLUENT software to obtain the carrying capacity features of the gas film. Finally
the structural static force of the precision air-bearing rotary stage will be analyzed by ANSYS software. The analysis results show that: the structural design of the precision air-bearing rotary stage is reasonable
and this structure can provide a larger range of loads. Even in heavy load conditions
a larger deformation will not occur any more. It has a good practical value
and also can be widely used in high precision equipments. (2012) Trans Tech Publications.

The azimuth bearing schemes in typical large Alt-azimuth telescopes
especially the 3.5-m APO telescope and the 4.1-m SOAR telescope were analyzed. A scheme of high-angular contacted thrust ball bearing integrated with a radial ball bearing was put forward. According to the Hertz contact theory
the corresponding parameters were designed for engineering application. The static performance parameters
within the range of 60 85 original contact angle were calculated. Compared with the traditional plane thrust ball bearing
the results shows that the high-angular (80) contact thrust ball bearing has more benefits at bearing strength and rigidity for large telescope. The 1500mm diameter prototyping bearing shows good performance
including the axial jitter is 0.009mm
the radial jitter is 0.006mm
the maximum starting torque without load is 30N·m
and the load capacity is more than 30t
which offers advanced technique path for the buildup of the high precision azimuth shafting and the whole telescope system. 2010 Copyright SPIE - The International Society for Optical Engineering.
