Abstract

The invention discloses a chain-wheel-driven dome base. The dome base comprises an annular base body, a driving device, a plurality of supporting roller devices and a limiting device. The driving device comprises a support, a motor, a reduction gearbox and a chain wheel, wherein the motor, the reduction gearbox and the chain wheel are arranged on the support, an output shaft of the motor is connected with an input shaft of the reduction gearbox through a belt, an output shaft of the reduction gearbox is fixedly connected with a rotating shaft of the chain wheel, and the rotating shaft of the chain wheel is vertically arranged. The motor drives the chain wheel to rotate, and the chain wheel and a chain are engaged to drive the base body to rotate around the center of the base body. The basebody is movably arranged on a circular roller way formed by a plurality of supporting wheels, and the base body rotates along the circular roller way formed by the supporting wheels by utilizing friction. Through engaging of the chain wheel and the chain, precision control is convenient, and the rotating angle of a dome can be accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of astronomical domes, in particular to a dome base driven by a chain wheel. Background technique [0002] The driving device of the existing astronomical dome is generally a roller located at the bottom of the dome base. The motor drives the roller to rotate, and the friction force between the roller and the dome base is used to drive the dome base to rotate, so as to realize the rotation of the dome, because the dome has a large volume. The weight is heavy, so the inertia is large during the rotation process, the control precision is poor, and the rotation angle cannot be accurately controlled. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a dome base driven by a sprocket, which solves the problem that the astronomical dome in the prior art is large in size and heavy in weight, and therefore has large inertia and poor control accuracy during the rotation process, an...
