AI Technical Summary
Existing technologies make it difficult to efficiently install the spherical bearings used in Boeing aircraft air conditioning systems, and traditional installation methods are prone to bearing damage, affecting rotational accuracy and increasing maintenance costs.
A tooling for installing ball bearings has been designed, including a base, a spindle, and functional components. By using a combination of positioning components, pressure components, and locking components, the coaxiality of the bearing and the lug is ensured and the installation is stable, thus preventing damage to the bearing during installation.
This enables rapid and accurate positioning and installation of spherical bearings, improving work efficiency, reducing maintenance costs, and ensuring the coaxiality and rotational accuracy of the bearing and lug.
