Steel Ball Recirculation Method<\/strong><\/td>\n| Explanation<\/strong><\/td>\n<\/tr>\n | \uff081\uff09<\/td>\n | End Cap<\/td>\n | Steel balls are recirculated by the end caps mounted within each end. Ball recirculation tunnels are constructed within the nut’s inner wall. Good with high speed operations.<\/td>\n<\/tr>\n | \uff082\uff09<\/td>\n | Deflector<\/td>\n | Deflectors are embedded on the nut outer tube to return the balls over the screw shaft per each lead. Suitable for compact designs.<\/td>\n<\/tr>\n | \uff083\uff09<\/td>\n | Return Tube<\/td>\n | Return tubes are mounted outside of the nut. The ease of assembly makes this suitable for mass production, however the overall size is relatively large compared to other methods.<\/td>\n<\/tr>\n | \uff084\uff09<\/td>\n | Guide Plate<\/td>\n | Uses guide plates or deflectors instead of the return tubes, and is good for making the design compact.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n |
Methods 1, 2, and 3 are shown in much more detail in Figure 2.<\/p>\n
Figure 2:<\/strong> In this figure we have three methods (In order of appearance): End Cap, Deflector, and Return Tube.<\/p>\n With a high level overview on the internal structure of ball screws, the concept of preloading will be easy to grasp. In the next article we will touch on preloading \u2013 the purpose and different methods.<\/p>\n |
