Example Embodiment
[0013] Example 1
[0014] figure 1 It shows that the bearing (1) of a backlash-free speed change mechanism of the present invention is installed in parallel with two rolling screws (3) and (4) and guide rails (7) with different leads. The rolling screws (3) and ( 4) Install the pre-tightening nuts (2) and (5) respectively, the transmission block (6) installed on the guide rail (7) is connected with the pre-tightening nuts (2) and (5), and two rolling screws (3) It is coaxial with the axis of (4).
[0015] figure 1 The working principle of a gapless speed change mechanism of the present invention is shown as follows: if the rolling screw (3) rotates, the pre-tightening nut (2) moves left and right, driving the transmission block (6) and the pre-tightening nut (5) along the guide rail (7) Move left and right, the left and right movement of the pre-tightening nut (5) makes the rolling screw (4) rotate. If the lead of the rolling screw (3) and the rolling screw (4) are different, ...

[0017] figure 2 It shows that the bearing (1) of a backlash-free speed change mechanism of the present invention is installed in parallel with two rolling screws (3) and (4) and guide rails (7) with different leads. The rolling screws (3) and ( 4) Install the pre-tightening nuts (2) and (5) respectively, the transmission block (6) installed on the guide rail (7) is connected with the pre-tightening nuts (2) and (5), and two rolling screws (3) The axis of (4) is different from the axis.
[0018] figure 2 The working principle of a gapless speed change mechanism of the present invention is shown as follows: if the rolling screw (3) rotates, the pre-tightening nut (2) moves left and right, driving the transmission block (6) and the pre-tightening nut (5) along the guide rail (7) Move left and right, the left and right movement of the pre-tightening nut (5) makes the rolling screw (4) rotate. If the lead of the rolling screw (3) and the rolling screw (4) are diffe...
