no. 1 Embodiment approach
[0020] The inventors of the present invention have developed an output gear plate that is easily mounted to a gear unit that performs rotational movement within a limited rotational range of less than 360°. In the first embodiment, an exemplary output gear plate will be described.
[0021] figure 1 It is a schematic front view of the output gear plate 100 of the first embodiment. refer to figure 1 The output gear plate 100 will be described.
[0022] figure 1 A rotation surface RTS of a gear unit (not shown) and a rotation center axis RAX of the rotation surface RTS are schematically shown. The rotating surface RTS rotates and reciprocates around the rotation center axis RAX within a limited rotation range less than 360°. When the output gear plate 100 meshes with a rack (not shown), the rotational reciprocating motion of the rotating surface RTS is converted into a linear reciprocating motion of an object member connected to the rack. If the output gear plate 100 meshes...
no. 2 Embodiment approach
[0031] The output gear plate described in connection with the first embodiment is formed of one member. Therefore, the portion attached to the rotating surface cannot be separated from the portion engaged with the target member. Alternatively, the designer may design the output gear plate so that the part attached to the rotating surface can be separated from the part meshed with the target member. In the second embodiment, an exemplary output gear plate formed of a plurality of members will be described.
[0032] figure 2 It is a schematic front view of an output gear plate 100A of the second embodiment. refer to figure 1 and figure 2 The output gear plate 100A will be described. The description of the first embodiment uses the same reference numerals as those of the first embodiment.
[0033] The output gear plate 100A includes a gear plate 140 and a mounting plate 150 . The gear plate 140 is combined with the mounting plate 150 . The mounting plate 150 is mounted ...
no. 3 Embodiment approach
[0041] The output gear plate described in connection with the first embodiment can be used as a part of various gear devices. In the third embodiment, an exemplary gear device will be described.
[0042] Figure 3A ~ Figure 3C The speed reducer 200 of the third embodiment is shown. Figure 3A is a schematic cross-sectional view of the speed reducer 200 . Figure 3B is along Figure 3A A schematic cross-sectional view of the speed reducer 200 shown along line A-A. Figure 3C is a schematic front view of the speed reducer 200 . refer to figure 1 , Figure 3A ~ Figure 3C The speed reducer 200 will be described. The description of the first embodiment uses the same reference numerals as those of the first embodiment. In the present embodiment, the gear unit is exemplified by a speed reducer 200 .
[0043] Such as Figure 3A As shown, the speed reducer 200 has an outer cylinder 300, a gear carrier 400, a gear part 500, and three crankshaft assemblies 600 ( Figure 3A One...
