Description

Displacement multiple transmission structure

The present invention relates to a power transmission structure, in particular to a displacement multiple of a multiple moving distance by which an active member can drive a driven member by simultaneous rotation (angular displacement) and linear motion (linear displacement) of the gear. Transmission structure.

In daily life, we often apply mechanical transmission structure to transmit power or change the state of motion. Generally, the common transmission structure includes gear transmission structure, belt transmission structure, pulley transmission structure, lever transmission structure, chain transmission structure, The rope wheel transmission structure, the wheel set transmission structure, etc., the shaft of the shaft must be fixed by the shaft to drive or move. There is no fixed axis, and it can only be driven by itself.

The gear transmission structure includes the gear and the gear meshing. When the gear belt drives the rack or the rack to drive the gear, the circular motion can be changed into a linear motion or the linear motion can be changed into a circular motion, but the gear usually rotates only as a circle. Movement without linear movement at the same time, that is, the mass point of the gear is fixed at the same point, the gear has only angular displacement, so how much angular displacement is generated when the gear rotates, and the linear motion distance of the rack driven by the gear is also equal to the gear rotation. The angular displacement, so there is no multiplication of transmission efficiency, the traditional gear, rack transmission structure still lacks to be improved.

Therefore, the inventor's concept of continuous innovation and improvement based on products is based on years of experience in the design and development of the product, as well as active research and development, and through numerous practical design experiments, the invention has been produced.

The actuating member 16 is linearly movable, and the actuating member 16 is provided with a notch 161. The notch 161 is sleeved on the first shaft body 11, so that the actuating member 16 can drive the first shaft body 11 to move linearly; The second transmission group 20 is disposed under the first transmission group 10, the second transmission unit 20 is provided with a second shaft body 21, the second shaft body 21 is pivotally disposed with two second gears 22, and the second gear 22 is meshed with the second side. The second rack 22 is engaged with a second movable rack 24 on the lower side of the second gear 22, and a second linkage 25 is disposed on the lower side of the second movable rack 24. The first linkage 15 is provided with an opening. The slot 151 is sleeved on the second shaft body 21, so that the second shaft body 21 can be linearly moved by the first linkage member 15.

The third transmission set 30 is located below the second transmission set 20 and can be driven by the second linkage 25 of the second transmission set 20. The configuration of the third transmission set 30 is the same as that of the second transmission set 20 and will not be described again.

The frame body 90 includes a dome-shaped bracket 91 disposed on two sides and disposed vertically, and a plurality of brackets 92 connected horizontally between the brackets 91 to form a three-layer frame body, and each floor has an equal height. The first transmission group 10, the second transmission group 20, and the third transmission group 30 are sequentially installed from top to bottom in each layer; wherein the first fixed rack 13, the second fixed rack 23, and the third fixed rack 33 are provided. The two ends can be fixed between the brackets 91, and the bracket 92 is additionally provided with a plurality of rollers 93, the first movable rack 14, the second activity The rack 24 and the third movable rack 34 are disposed on the roller 93 so as to reduce the frictional resistance, so as to facilitate the linear movement of the first movable rack 14, the second movable rack 24, and the third movable rack 34.

Referring to the fourth figure, in the present invention, the actuating member 16 is used as an active member, and a motive force is applied to the actuating member 16 for linear movement (this embodiment is moved to the right), and the first shaft body 11 is driven. Linear motion, because the first gear 12 is pushed by the first shaft 11 and the first fixed rack 13 and the first movable rack 14 are vertically engaged, the first gear 12 can be used in the first fixed rack 13, the first activity The racks 14 rotate simultaneously (the first gear 12 rotates counterclockwise in this embodiment) and the linear motion (the present embodiment moves to the right), thereby driving the first movable rack 14 to move linearly; the second transmission group 20 The second shaft body 21 can be driven by the first linking member 15, and the second movable rack 24 can be linearly moved in the same manner as the principle of the first transmission group 10; the third shaft body 31 of the third transmission group 30 can be The second linkage 25 is driven, similar to the principle of the second transmission set 20, to linearly move the third movable rack 34.

According to the present invention, the first movable rack 14, the second movable rack 24, and the third movable rack 34 (ie, the follower) can be multiplied by a moving distance relative to the actuating member 16 (ie, the active member). For example, when the first gear 12 rotates counterclockwise, angular displacement and linear movement to the right are simultaneously generated, and at the same time, the first movable rack 14 is driven; assuming that the linear value of the first gear 12 is 1 cm, The first movable rack 14 driven by the angular displacement of the first gear 12 is also 1 cm, and the first movable rack 14 is moved 2 cm to the right in total.

The second movable rack 24 is moved 4 cm to the right, and the third gear 32 is again driven to generate an angular displacement and a linear movement to the right, that is, the third gear 32 rotates to generate an angular displacement, which can drive the third movable rack 34 to 4 cm. And the third gear 32 moves linearly by 4 cm, and the third movable rack 34 moves a total of 8 cm to the right.

In analogy with the above principle, when ten sets of transmission groups are provided, the movable rack of the tenth group of transmissions will move 1024 cm to the right according to the operation.

Similarly to the above principle, when there are twenty sets of transmission groups, the movable rack of the twentieth group transmission group will move to the right to reach 1048576 cm after the operation.

Referring to the fifth figure, the present invention can only provide the first transmission group 10 and the second transmission group 20 according to actual needs.
