- the idle gears 241 and 242 can revolve around the center of the second intermediate gear 244.
- two idle gears 241 and 242 are rotatably mounted on both ends of the rotation shaft 243. Both ends of the rotation shaft 243 protrude through the idle gears 241 and 242, and both ends of the rotation shaft 243 are fitted into the grooves 247 formed on the inner circumferential surface of the second intermediate gear 244, respectively. Therefore, when the second intermediate gear 244 rotates, the rotation shaft 243 also rotates together, and the idle gears 241 and 242 mounted on the rotation shaft 243 are in the same direction as the rotation direction of the second intermediate gear 244. Will be orbited.
- the idle gears 241 and 242 rotate while being engaged with the first and second bevel gears 232 and 233 to rotate. Since the rotating shaft 243 rotates due to the idle of the idle gears 241 and 242, the output unit 201 connected to the rotating shaft 243 rotates.
- the third one-way bearing 235 may be formed in the third intermediate gear 234. That is, the third one-way bearing 235 is mounted between the third intermediate gear 234 and the fixed shaft 236.
- reference numeral 203 denotes a case.
- FIG. 13 shows the principle of synthesizing the torque of the input. That is, the power transmission process in the case of combining the torque of the first rotational force provided from the first input unit 210 and the torque of the second rotational force provided from the second input unit 220.
- the first input unit 210 rotates in a clockwise direction and the second input unit ( Torque may be synthesized when 220 is rotated counterclockwise (see solid arrow in FIG. 13). That is, the torque may be synthesized when the second input unit 220 rotates in the reverse direction.
- the first input gear 212 rotates in the same direction to generate a first rotational force.
- the first rotational force is transmitted to the first intermediate gear 231 engaged with the first input gear 212.
- the first bevel gear 232 also rotates in the same direction.
- the idle gears 241 and 242 rotate by the rotation of the first bevel gear 232. Since the idle gears 241 and 242 rotate, the second bevel gear 233 and the third intermediate gear 234 engaged with each other try to rotate in a direction opposite to the first bevel gear 232, but the third one-way bearing 235 does not rotate.
- the second bevel gear 233 Since the rotation of the third intermediate gear 234 is prevented, the second bevel gear 233 is also unable to rotate. If the speed is synthesized, the output is generated because the input is driven to prevent the second bevel gear 233 from rotating in the opposite direction to the first bevel gear 232, but in the case of torque synthesis, the second bevel gear If 233 does not prevent the first bevel gear 232 from rotating in the opposite direction, no output is generated, and the idle gears 241 and 242 only rotate and revolve. Thus, a third one-way bearing 235 is needed to produce an output in the case of torque synthesis. That is, in the case of torque synthesis, rotation of the third intermediate gear 234 is blocked by the third one-way bearing 235, and as a result, the second bevel gear 233 also does not rotate.
- the output unit 201 connected to the rotation shaft 243 also rotates in the same direction (counterclockwise direction). Through this process, the first rotational force of the first input unit 210 is transmitted to the output unit 201.
- the second input gear 222 when the power shaft 221 of the second input unit 220 rotates counterclockwise, the second input gear 222 does not rotate but only the third input gear 223 rotates in the same counterclockwise direction.
- the rotational force of the second input gear 222 is transmitted to the second intermediate gear 244 via the fourth intermediate gear 245. That is, the torque of the second intermediate gear 244 generated by the first input unit 210 and the torque of the second intermediate gear 244 transmitted by the second input unit 220 are added to each other.
- the torque of the second intermediate gear 244 added as described above is transmitted to the output shaft 201 through the rotation shaft 243. In this manner, the torque of the first input unit 210 and the torque of the second input unit 220 are combined.
- the velocity may be synthesized when the rotation directions of the first rotational force generated by the first input unit 210 and the second rotational force generated by the second input unit 220 are the same (clockwise in FIG. 14). That is, the speed may be synthesized when the second input unit 220 rotates in the same direction as the rotation direction of the first input unit 210 (clockwise) (see solid arrow in FIG. 14).
- the second input gear 222 and the third input gear 223 should rotate, and the first one-way bearing 224
- the second input gear 222 is rotated by, but the third input gear 223 is turned by the second one-way bearing 225. That is, although the third input gear 223 rotates, it does not transmit the rotational force to the second intermediate gear 244.
- the second input gear 222 is engaged with the third intermediate gear 234 to transmit rotational force to the third intermediate gear 234, and the third intermediate gear 234 is an idle gear through the second bevel gear 233.
- 241 and 242 are revolved and the rotational force is transmitted to the output unit 201 connected to the rotation shaft 243.
- the idle gears 241 and 242 do not rotate. Only idle. If the rotation speeds of the first bevel gear 232 and the second bevel gear 233 are different, the idle gears 241 and 242 rotate in a specific direction and the first bevel gear 232 and the second bevel gear 233 are rotated. In the same direction as).
- the air power of the idle gears 241 and 242 rotates the output shaft 201 through the rotation shaft 243. That is, the idle speed of the idle gears 241 and 242 becomes the speed of the output shaft 201.
- the idle speeds of the idle gears 241 and 242 by the first input unit 210 and the idle speeds of the idle gears 241 and 242 by the second input unit 220 are added to the first input unit 210 and the second input unit. The speed of 220 is added.
- the first bevel gear 232 and the second bevel gear 233 are always rotated in the same direction.
- the rotation directions of the idle gears 241 and 242 are determined by the speed difference between the first bevel gear 232 and the second bevel gear 233.
- the input synthesizing apparatus 100 when the input synthesizing apparatus 100 according to the present invention includes three one-way bearings and a planetary gear unit, directions of the first rotational force provided by the first input unit and the second rotational force provided by the second input unit are mutually different. If they are the same, the torques are synthesized, and if the directions are different, the speeds can be synthesized to produce outputs having various speeds and torques.
- the present invention can be used in the technical field required to generate a variety of outputs by synthesizing a plurality of inputs, such as robots, transportation devices, moving means.
