an equatorial mount

Abstract

The invention discloses a novel equatorial telescope which comprises a base, an hour angle mechanism, a drift angle mechanism and the like. An hour angle worm gear and a drift angle seat are arranged on an hour angle shaft in a sleeving mode respectively, a fit clearance of the hour angle worm gear and the hour angle shaft is in accordance with that of the drift angle seat and the hour angle shaft, an hour angle shaft worm is fixed on a set position of the drift angle seat and meshed with the hour angle worm gear, when the hour angle worm gear is locked with the hour angle shaft under the action of a clutch locking mechanism, the hour angle worm rotates around the hour angle worm gear, and therefore the drift angle seat is driven to rotate around the hour angle shaft. According to the novel equatorial telescope, the hour angle worm gear and the drift angle seat are arranged on the hour angle shaft in a sleeving mode respectively, and the fit clearance of the hour angle worm gear and the hour angle shaft is in accordance with that of the drift angle seat and the hour angle shaft; due to the fact that only one type of the fit clearance exists, accumulation of fitting errors does not exist, and therefore the bearing capacity of the equatorial telescope is increased, precision of celestial body tracking is improved, and the stability is improved.

Description

technical field [0001] The invention relates to an equatorial mount, in particular to an equatorial mount bracket with an innovative structure, belonging to the technical fields of astronomy and measurement. Background technique [0002] An equatorial mount is a common instrument for measuring angles. It is usually used in conjunction with astronomical telescopes for astronomical observations, and provides measurement scientific data for astronomical phenomena and astronomical research. Generally speaking, because the equatorial mount must make compound angle adjustments in three-dimensional space, its bracket must have high precision, so that the observation angle of the matching telescope can be accurately adjusted to achieve precise positioning of celestial bodies and real-time track. [0003] The existing equatorial mount bracket generally mainly includes a base, an hour angle mechanism and a deflection mechanism. The hour angle mechanism is connected to the base and ca...

Problems solved by technology

[0004] However, the above-mentioned equatorial mount bracket also has certain defects: the hour angle worm gear is sleeved on the hour angle shaft, and there is a fit gap 1; Errors will accumulate in the fit gap, resulting in poor load-bearing capacity of each part and poor stability of the equatorial mount
