Embodiment 1

[0027]Embodiment 1, the supporting system of the azimuth axis of the large South Pole Telescope. With reference to accompanying drawing: telescopic lens barrel 1 is supported on both sides yoke 4 by the support bearing 3 of the height axis 2 of its both sides, and two yokes 4 on both sides pass weight on the azimuth turntable 5, between azimuth turntable 5 and base 7 The connection mode between is: base 7 is provided with arc-shaped guide rail 11 and several slide blocks 10 matched therewith; The curved guide rail 11 is fixed to the base 7 by guide rail coupling screws 13 . The entire circle of the arc-shaped guide rail 11 is formed by splicing a plurality of arc segments. The setting method of the slider is as follows: 2 sliders are arranged under the fork arms on both sides: 0° and 180° respectively; 1 slider is also arranged respectively in the vertical 90° and 270° directions of the fork arms on both sides. . 9 in the figure is the azimuth axis.

Abstract

The invention relates to a support system for an azimuth axis of a large south-pole telescope. A telescope barrel is supported on two fork arms by support bearings of height shafts at the two sides ofthe telescope barrel; and the two fork arms at the two sides transmit the weigh to an azimuth turntable. The azimuth turntable and a pedestal are connected as follows: an arc-shaped guide rail and aplurality of sliding blocks matching the guide rail are arranged on the pedestal; and the upper portions of the sliding blocks are fixed with the bottom of the turntable. A problem that the hydrostatic bearing can not be used because the low temperature at the South Pole reaches minus 89 DEG C in the prior art is solved. The rotary bearing has the large diameter reaching over 4 meters; the friction torque generated by the support is small, so that the requirement of the tension energy supply of the South Pole is met; and because of the stable support, the stable tracking and pointing of the south-pole astronomical telescope are realized. Compared with the prior art, the support system has the following advantages: the contact between the radial positioning angle and the ball bearing set and the positioning azimuth axis is avoided.

Description

technical field [0001] The invention relates to a supporting system of a mechanical rotating shaft system, in particular to a novel azimuth shaft supporting system of a large Antarctic telescope. Background technique [0002] The data of the Antarctic expedition show that the atmosphere in the Antarctic is thin, cold, dry, with little dust, less atmospheric turbulence, and good seeing. More importantly, continuous astronomical observations (polar nights) can be carried out in the Antarctic for several months. And less environmental light pollution. These features make the conditions for astronomical observation in Antarctica unmatched anywhere else on Earth. Therefore, the international astronomical community is vigorously developing Antarctic astronomy. China has also started related astronomical research at Dome A in Antarctica. It has successively installed medium and small astronomical telescopes such as CSTAR and AST3 in Dome A. These telescopes are small in diameter a...
