What ball circulation mechanisms does the Ball Screw have?
The circulation mechanism can be roughly divided into four types: return pipe, deflector, end cap, and return plate types. The return pipe type is the most popular one in which balls are picked up from the screw shaft by a pipe, pass through the tube and return to their original position, maintaining continuous rolling motion. The deflector type has the most compact nut. Balls change course with a deflector, climb over the outer diameter of the screw shaft, and return to their original position. The end cap type has a nut suitable for high speed feed. Balls are picked up from the screw shaft by the end cap, pass through the through hole of the nut, and return to their original position. In the return plate type, balls picked up by a coil-type deflector circulate along the return plate groove. The return plate system, which is more compact in size than the return pipe system, is used for the Miniature Ball Screw.
