Plantary Screws For Planetary Screw Barrel Set

Plantary Screws For Planetary Screw Barrel Set

The composition of the planetary screw barrel mainly includes the central screw, planetary screws, and barrel.

The central screw is an active screw, with multiple small diameter screws meshing and rotating around its outer circumference. These small diameter screws can both rotate on their own and revolve around the central screw. This is because the outer periphery of the small screw also has an outer sleeve with helical teeth meshing with it.

The barrel and the front and rear barrels are connected and fixed with bolts, and the threaded section of the screw is an involute tooth shape, with a multi head screw thread.
