Split type two-shaft driving mechanism

Abstract

The invention discloses a split type two-shaft driving mechanism which comprises an A-axis driving mechanism, a folding assembly, a B-axis driving mechanism and a connecting frame. The A-axis driving mechanism and the B-axis driving mechanism are designed in a split mode, the A-axis driving mechanism and the B-axis driving mechanism can fully inherit the technical state of an existing mature single-axis driving mechanism, the product maturity is high, the structure is simple, the reliability is high, the A-axis driving mechanism is connected with the B-axis driving mechanism through the folding assembly, and the integration degree of the driving mechanisms and the solar cell array is improved; and an output shaft of the A-axis driving mechanism is connected with one end of the folding assembly, the other end of the folding assembly is connected with the connecting frame, the connecting frame is fixedly connected with the solar cell array, and an output shaft of the B-axis driving mechanism is connected with the solar cell array through the connecting frame. The A-axis driving mechanism drives the B-axis driving mechanism, the folding assembly and the solar cell array to achieve the 360-degree sun-facing orientation function, and the B-axis driving mechanism is used for driving the solar cell array to swing.

Description

technical field [0001] The invention belongs to the application field of satellite technology, and in particular relates to a two-axis driving mechanism of a split solar cell array. Background technique [0002] The driving and transmission of the satellite solar cell array is generally realized through the driving mechanism. The driving mechanism, as the connection device between the solar cell array and the star, is responsible for driving the solar cell array to align with the sun, and at the same time transmit the current and signal converted by the solar cell array to the star. [0003] The general driving mechanism only needs one degree of freedom, but for some complex orbits or satellites with special application purposes, the incident angle of the battery array to sunlight changes greatly within one orbital period, and the single-degree-of-freedom driving mechanism can no longer guarantee a good solar environment. The incident angle of light requires the use of a two-...

Problems solved by technology

[0003] The general driving mechanism only needs one degree of freedom, but for some complex orbits or satellites with special application purposes, the incident angle of the battery array to sunlight changes greatly within one orbital period, and the single-degree-of-freedom driving mechanism can no longer guarantee a good solar environment. The incident angle of light requires the use of a two-degree-of-freedom drive mechanism. At present, the various spacecraft that have been launched in my country, the solar panels mostly use a single-degree-of-freedom drive mechanism, and the two-degree-of-freedom drive mechanism is rarely used, and most of them are two-axis integrated design , Product stability, inheritance, versatility are poor, and the weight is heavy
