Embodiment Construction
[0025] Such as figure 1 , 2 As shown, a lubricated bearing suitable for a multi-degree-of-freedom spherical motion device includes a complete spherical inner shell 1 and a non-complete spherical outer shell 2, the inner shell 1 is installed in the outer shell 2, and the The outer surface of the inner shell 1 and the inner surface of the outer shell 2 are spherical surfaces with overlapping spheres, which can complete multi-degree-of-freedom movements and have a strong bearing capacity; when the opening of the outer shell 2 is closed, it is connected and fixed by two bolt assemblies. The bolt assembly includes nuts 6 and bolts 7 , the two incomplete hemispherical shells of the casing 2 are aligned, and then the bolts 7 pass through the connecting holes on the casing 2 and are screwed and fixed by the nuts 6 . The design of the split shell makes the installation of the inner shell more convenient, without heating, it can be directly installed inside the shell, the installation ...
