Embodiment Construction
[0030] Combine below Figure 2 to Figure 6 , the present invention is further described:
[0031] Such as Figure 2-Figure 4 As shown, a miniature ball screw integrated bearing assembly includes a nut 101 and a screw 102. Between the nut 101 and the screw 102, the ball 106 of the screw is used as a rolling body to convert the rotational motion of the nut 101 into a screw. Linear motion of the bar 102. Also includes a bearing, the bearing includes a bearing outer ring 104 and a bearing inner ring, a bearing steel ball 108 and a sealing ring 107 are arranged between the bearing outer ring 104 and the bearing inner ring, and the bearing steel ball 108 is fixed on the bearing outer ring 104 by a cage 105 and the inner ring of the bearing. The bearing inner ring and the screw nut 101 are integrated into one piece. The inner ring of the above-mentioned bearing is integrated with the screw nut. Compared with the prior art bearing interference fit and pressing into the screw nut, ...
