A navigation inertial group indexing locking mechanism with self-locking electromagnetic brake cooperative mechanism

Abstract

The invention relates to a navigation inertial group indexing and locking mechanism for self-locking of an electromagnetic braking cooperative mechanism, which belongs to the technical field of space navigation control. The purpose is to solve the problems existing in the prior art that the tooth plate of the mechanism is stuck and the test cannot be continued, the failure rate is high, the error of the mechanism test is large, the state of the mechanism cannot be switched freely, and the test efficiency is low. The invention comprises: a mechanism frame; a transmission shaft system located in the mechanism frame and rotatingly matched with the mechanism frame, the transmission shaft system at least includes a first transmission locking shaft, a hollow shaft and a second transmission locking shaft arranged coaxially in sequence; and a second A driving self-locking device connected to the end of the transmission locking shaft, through the driving self-locking device to realize the driving self-locking and the rotation drive of the transmission shaft; and the electronic braking device connected to the end of the second transmission locking shaft, through The electromagnetic braking device brakes the transmission shaft system; and the high-precision split test device measures the angle change of the navigation unit located in the hollow shaft through the high-precision split test device.

Description

technical field [0001] The invention belongs to the technical field of space navigation control, and in particular relates to a navigation inertial group indexing and locking mechanism which is self-locked by an electromagnetic brake coordination mechanism. Background technique [0002] From the completion of assembly to the launch of the missile, it must be self-calibrated to ensure that the error of the navigation inertial group test data is smaller and the flight direction is more accurate. The inertial group indexing / locking mechanism is an important part of the navigation inertial group self-calibration system. Its function is to control the navigation inertial group to rotate at a specified angle and lock the specified position according to the calibration requirements. With the wide application of space navigation control technology, the current navigation control system is developing towards higher precision, smaller size and lighter weight. [0003] The inertial gr...
