The two ends of the ball screw can be installed on the fixed seat and the support seat after processing. The support seat is the same name of the two. It is to put a bearing in the finished mold to match the rotation of the ball screw. . Now let the trapezoidal screw manufacturers introduce the common support methods of ball screws.
1. One end is fixed with double bearings, and the other end is cantilever. Most of them are used for short stroke and vertical transmission.
2. One end is fixed by a double bearing, and the other end is supported by a single bearing. The structure is relatively simple. The only disadvantage is that the rigidity of the single bearing end is lower.
3. 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 the single bearing end support.
4. Finally, one end is fixed by dual bearings, and the other end is supported by dual bearings. 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 for large bidirectional loads and spans. Use it when you are older.
