The two ends of the ball screw can be installed on the fixed seat and the support seat after processing. The support seat is a unified name for these two. It is to put a bearing in the finished mold to match the rotation of the ball screw. . In fact, it is installed on both ends of the ball screw to fix the screw.
There are several common support methods for ball screws: one end is fixed by double bearings, and the other end is cantilever. Most of them are used for short stroke and vertical transmission. There is also a double bearing fixed at one end, and a single bearing at the other end. The structure is relatively simple. The only disadvantage is that the rigidity of the single bearing end is lower. In addition, one end is fixed by double bearings, and the other end is supported by double bearings. The structure is slightly more complicated, but the rigidity is better than that of single bearing end. There is also a dual bearing fixed at one end and a dual bearing support at the other end. The structure is slightly complicated, but the axial rigidity is better, and it is not easy to shake when rotating at high speed. It is especially used for horizontal layout, especially when the two-way load is large and the span is large. use.
