An auxiliary device for balancing and counterweighting satellite payloads

Abstract

The invention provides an auxiliary device of satellite load whole machine dynamic balance weight. According to the structure, the auxiliary device comprises a weight support, fixing supporting boards and a rubber board; the weight support comprises a U-shaped board and a fixing sheet arranged at the outer side of the bottom of the U-shaped board; the fixing supporting boards are connected to the two side portions of the U-shaped board; the rubber board is connected to the inner side of the bottom of the U-shaped board and is in contact with a rotary cylinder; the side portion of the U-shaped board is clamped in a window of a bearing cylinder and the fixing sheet is in bolt connection with the outer wall of the bearing cylinder, so that the device is fixed to the bearing cylinder; each balancing weight is provided with technical threads, through holes matched with the technical threads in position are formed in each fixing supporting board, each screw penetrates through one through hole and is arranged through the technical threads, and therefore the balancing weights is fixed to the device. According to the auxiliary device of the satellite load whole machine dynamic balance weight, the safety quality problems possibly caused by repeated disassembly and assembly of the balancing weights in satellite load whole machine dynamic balance can be effectively solved, operation can be independently completed by a technician, and the auxiliary device has the advantages of being safe, stable and the like.

Description

technical field [0001] The invention relates to the technical field of dynamic balance counterweights of aircraft, in particular to an auxiliary device for dynamic balance counterweights of satellite loads. Background technique [0002] With the development of aerospace technology, more and more large inertia rotating parts are used on satellites, and the scanning motion of payload rotating parts will produce periodic attitude disturbances during orbital flight. In order to ensure the final attitude stability of the satellite in orbit, it is necessary to carry out tests under the complete machine state such as the complete maneuvering balance test. The main object of the test is the original product, while the installation of the counterweight and the protection of the fasteners are It is a key link to ensure the success of the test, product safety, and the smooth completion of important tests. [0003] At present, due to the structural limitations of the satellite payload,...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the structural limitations of the satellite payload, a small counterweight window is placed on the main load-bearing cylinder for the test personnel to perform counterweight operations; due to the large gap between the main load-bearing cylinder and the rotating cylinder In order to achieve a certain weight, the counterweight must be made as large and thin as possible, which increases the difficulty of counterweight operation; at the same time, because the dynamic balance counterweight often needs to be repeated several times, the counterweight must be repeated several times. Several times of assembly and disassembly can easily cause fasteners to fall. Therefore, the protection of fasteners needs to be paid attention to during operation. Once the fasteners fall into the gap due to careless operation, it will affect the installation of the counterweight, The smooth progress of the disassembly work has a great impact; in addition, the rotating cylinder is in a free state during the counterweight, and it is also because of the relative movement between it and the main load-bearing cylinder that the assembly and disassembly of the counterweight is more likely to cause quality problems

[0004] At present, there is no report on the counterweight auxiliary device that can effectively solve the above problems in the market
