Abstract

The invention provides a steering device for a satellite vibration test. The steering device comprises a baseplate, a big chain wheel, a rolling bearing, a transmission chain and a small chain wheel hand-operated device, wherein the baseplate is fixed on a sliding table through vibrating table connection holes, the inner ring of the rolling bearing is connected with a central shaft on the baseplate through retaining keys, the big chain wheel is connected with the outer ring of the rolling bearing through key slots, and the small chain wheel hand-operated device and the big chain wheel are connected with each other through the transmission chain to form a chain wheel transmission reducing mechanism. When the entire device changes direction, fastening screws are dismounted from screw holes and the small chain wheel hand-operated device is rotated by a person, so that the big chain wheel generates stable and slow steering movement through the transmission ratio of the chain wheel mechanism and the lubrication action of the rolling bearing and balls. Therefore, the problem that the original steering mode requires complex satellite disassembly and causes time wage and potential safety hazard is solved. The steering device achieves the benefits of low manufacturing cost, excellent performance, convenience and straightforwardness in use, strong adaptability and universality, and the like.

Description

technical field [0001] The invention relates to the steering of a satellite in a horizontal vibration test, in particular to a disassembly-free steering device for a horizontal vibration test satellite. Background technique [0002] The current development of my country's satellites is characterized by large-scale, large batches, and short cycles. Under this background, satellite spreaders become more complicated, and disassembly and assembly are more time-consuming. Since most satellites currently use pressure rings for vibration tests, Therefore, its horizontal test turning time will be greatly increased. Taking the large-scale satellite under research as an example, it takes 2 hours to turn horizontally once, and several people are involved in the operation. For satellites undergoing tests of two orders of magnitude for identification and acceptance, the horizontal direction needs to be turned twice, which requires 4 hours or half a day. If satellites are mass-produced i...
