Rolling friction sine mechanism

[0016] Embodiment one:

[0017] refer to figure 1 , 2 , a rolling friction sinusoidal mechanism, including a first motion mechanism and a second motion mechanism, the first motion mechanism includes a reciprocating member 1, a first linear guide rail assembly, a slider 2, a rotating member 3 and a rotating input shaft 4 , the slider 2 is slidingly connected to the reciprocating part 1 through the first linear guide rail assembly; the second motion mechanism includes the reciprocating part 1, the second linear guide rail assembly and the body 5, and the reciprocating part 1 and the body 5 pass through the second linear guide rail The components are slidingly connected; the movement direction of the reciprocating member 1 generated by the first movement mechanism relative to the slider 2 is perpendicular to the movement direction of the reciprocating member 1 generated by the second movement mechanism relative to the body 5; the slider 2 passes through the bearing 14 Connected with the rotating member 3, the rotating member 3 is fixed on the rotating input shaft 4, the first linear guide assembly in the first motion mechanism includes the first guide rail column 7, the first rolling body 9 and the first guide rail block 11, Wherein the working surface of the first guide rail column 7 and the first guide rail block 11 is provided with a longitudinally arranged first rolling groove, the first rolling body 9 is installed in the first rolling groove, and the first guide rail The column 7 is connected with the first guide rail block 11 through the rolling friction of the first rolling body 9; the second linear guide rail assembly in the second motion mechanism includes the second guide rail column 6, the second rolling body 8 and the second guide rail block 10, Wherein the working surface of the second guide rail column 6 and the second guide rail block 10 is provided with a longitudinally arranged second rolling groove, the second rolling body is installed in the second rolling groove, and the second The guide rail bar 6 is in rolling friction connection with the second guide rail block 10 through the second rolling body 8 . The connection mode of the first movement mechanism is: the first guide rail column 7 is fixedly connected to the first reciprocating member 1 , and the first guide rail block 11 is fixedly connected to the slider 2 . The connection mode of the second movement mechanism is as follows: the second guide rail bar 6 is fixedly connected with the second reciprocating moving part 1 , and the second guide rail block 10 is fixedly connected with the machine body 5 .

[0018] The rotary motion provided by the power source drives the rotary shaft 3 to rotate by turning the input shaft 4, and the rotary shaft 3 drives the slider 2 to drive the reciprocating component 1 along the second linear guide component through the first linear guide assembly on the reciprocating component 1. Sine regular reciprocating motion.

[0019] Embodiment two:

[0020] refer to Figure 3-5 , the connection mode of the first movement mechanism is: the first guide rail column 7 is fixedly connected to the first reciprocating member 1, and the first guide rail block 11 is fixedly connected to the slider 2. The connection mode of the second movement mechanism is as follows: the second guide rail block 10 is fixedly connected to the reciprocating member 1 , and the second guide rail column 6 is fixedly connected to the machine body 5 . Others are the same as embodiment one.

[0021] The rotary motion provided by the power source drives the rotary shaft 3 to rotate by turning the input shaft 4, and the rotary shaft 3 drives the slider 2 to drive the reciprocating component 1 along the second linear guide component through the first linear guide assembly on the reciprocating component 1. Sine regular reciprocating motion.
