Internal Circulation & External Circulation
The ball circulation methods in ballscrews include internal circulation and external circulation.
- Internal circulation: The advantages of the internal circulation method are that the ball circulation loop is short, smooth, efficient, and the radial size of the nut is small. Its disadvantages are that the reverser is difficult to process and assembly and adjustment are inconvenient.
- External circulation: The ball circulation loop is long, the fluidity is poor, and the efficiency is low; the process is simple, the radial size of the nut is large, and it is easy to manufacture; the ball retainer has poor rigidity and is easy to wear
