Abstract
Description
Technical Field
[0001] The utility model belongs to the field of measuring tool workpieces, and particularly relates to a measuring tool for the axial clearance of an inertial gyro universal bracket component. Background Technique
[0002] As an important component of a terminal guidance shell, an inertial gyro uses its characteristic of axis fixation to measure the pitch and roll postures of the shell body. The control system, based on this posture information and combined with the target azimuth information measured by the seeker, controls the driving device to work, enabling the shell body to fly towards the target or a designated area.
[0003] The terminal guidance shell is a success or failure type product for one-time flight work, and the impact overload during its launch is as high as 10,000g. Therefore, as a detection device for the roll and pitch posture information of the terminal guidance shell, the inertial gyro must first be able to withstand the large overload of 10,000g during gun launch. The axial clearance of the universal bracket, as the buffer clearance for the inertial gyro to resist high overload, accurate measurement and quantification are very important. Currently, the axial clearance can only be perceived by experience, and the designed clearance index cannot be quantitatively measured using a tooling.
[0004] Therefore, it is necessary to design a measuring tool for the axial clearance of the universal bracket to accurately measure the axial clearance. Content of the Utility Model

The rotor shaft 204 passes through the hole of the rotor cover 208. The gasket 207 is installed on the rotor shaft 204, and the claws of the gasket 207 are inserted into the keyway of the rotor shaft 204. The bracket spring 203 is sleeved on the rotor shaft 204. The coarse adjustment nut 205 is screwed onto the thread at the upper end of the rotor shaft 204 with a balance screwdriver.
