Definitions
- the present invention relates to a power transmission device having a hollow shaft.
- a power transmission device that transmits input power to a counterpart machine is mainly used as a speed reducer. This means that when using an electric motor or the like as a drive source for driving a conveyor that does not require high-speed rotation or for a joint of an industrial mouth bot, use an electric motor with a high rotation and low torque as it is. Is inappropriate, and it is necessary to decelerate the motor rotation to the required number of rotations and increase the torque.
- the shaft passing through the power transmission device may be designed to be hollow so that a power cord, other control wiring, a cooling water pipe, and the like are passed through the shaft (for example, Japanese Patent Laid-Open No. Hei. 7—108485).
- the present invention prevents more damage to the inserted wiring and the like due to contact and friction, and maximizes the effective utilization of the originally designed hollow portion, so that more wiring and piping can be used.
- An object of the present invention is to provide a power transmission device that can be inserted through the air shaft.
- the present invention comprises a hollow shaft that penetrates the entire apparatus and rotates, and a protective portion for protecting a member inserted through the hollow shaft on an inner peripheral surface of an end of the hollow shaft;
- the present invention by providing a protective portion on the inner peripheral surface of the end of the hollow shaft, even if contact friction occurs between the hollow shaft and the wiring or the like, the presence of the protective portion causes the contact at the time of the contact. By reducing the surface pressure and friction, damage to the wiring and piping, disconnection, etc. can be prevented.
- a protective part is provided at the "end part" because the force that pays attention to the fact that some parts in the hollow shaft are easily contacted and damaged is not caused by any part in the hollow shaft. It is.
- the end of the hollow shaft is often contacted because the shape of the member has an acute angle, and in addition, for the convenience of wiring, it is often bent and placed immediately after passing through. This is because damage is likely to occur.
- the structure is simpler and the cost can be reduced compared to the case where a second hollow shaft (protective pipe) is separately inserted into the entire interior of the hollow shaft.
- the “end” can easily form a “step” with a larger diameter due to its structure, for example, by providing a protective portion at the step, the originally designed hollow portion can be maximized. It can be used as much as possible.
- the “hollow shaft” in the present invention is not necessarily limited to a single member, and is configured by combining a hollow input shaft and a hollow gear, pulley, or the like. It is a concept that includes things.
- FIG. 1 is an example of an embodiment of the present invention, and is an overall side cross-sectional view of a geared motor including a power transmission device in which an input shaft is a hollow shaft through which wiring or the like is passed.
- FIG. 2 is an example of an embodiment of the present invention, in which the output shaft is a hollow shaft through which wiring or the like is passed.
- FIG. 1 is a partial cross-sectional view of a geared motor GM100 including a power transmission device 160 to which an example of an embodiment of the present invention is applied.
- the geared motor GM100 includes a motor 102 and a power transmission device 160 coupled to and integrated with the motor 102, and is configured to transmit power to a counterpart machine 180 (not shown).
- a pinion 106 is formed on the motor shaft 104 of the motor 102, and meshes with the gear 108.
- the gear 108 is fixed to the input shaft 140 of the power transmission device 160.
- the input shaft 140 is formed with an eccentric body 120, and the input shaft 140 is also an eccentric body shaft 142 at the same time.
- An external gear 112 is rotatably supported on the eccentric body 120 via an eccentric body bearing 118, and the external gear 112 can swing and rotate as the eccentric body 120 rotates.
- the external gear 112 meshes with an internal gear 136 having internal teeth 110 with a slight difference in the number of teeth.
- the internal gear 136 is formed integrally with the casing 137 of the power transmission device 160, and is the casing 137 as well as the internal gear 136.
- the external gear 112 has external teeth such as a trochoidal tooth shape and an arc tooth shape on the outer periphery, and further has a plurality of inner pin holes 146, into which the inner pins 114 and the inner rollers 116 are fitted.
- a carrier pin hole 147 is formed in the external gear 112, and a carrier bolt 130 is fitted.
- the second output flange body 132 and the first output flange body 134 are integrally connected by the carrier bolt 130.
- the second output flange body 132 is rotatably supported by the internal gear 136 via a bearing 126.
- the input shaft 140 eccentric body shaft 142
- a bearing 122 is rotatably supported via a bearing 122.
- the first output flange body 134 rotates to the internal gear 136 via the bearing 128. Supported as possible. Further, the input shaft 140 is rotatably supported via a bearing 124.
- the internal gear 136, the connected second output flange body 132 and the first output flange body 134, and the input shaft 140 each independently have an axis Ol. It can be rotated to the center.
- the first output flange body 134 is connected to the counterpart machine 180 by a bolt (not shown) or the like.
- Friction reduction bearing 150 is attached to the expanded part.
- the friction reducing bearing 150 has an outer ring 150a fixed to the input shaft 140, and the inner ring 150b can freely rotate via a ball 150c.
- the driving force of the motor 102 is transmitted to the input shaft 140 via the motor shaft 104, the pinion 106, and the gear 108.
- the input shaft 140 rotates about the axis Ol, and accordingly, the eccentric body 120 integrally formed with the input shaft 140 also rotates.
- the external gear 112 also tries to swing and rotate around the input shaft 140 by the rotation of the eccentric body 120.
- the external gear 112 is the internal gear. While inscribed in 136, almost only rocks.
- the wire 190 is passed through the hollow portion of the input shaft 140 (eccentric body shaft 142), the input shaft 140 rotating at high speed and the wire 190 can directly contact each other. There is sex. However, in the part other than the end of the hollow input shaft 140, wiring etc. 190 may be passed straight through, and there is almost no possibility of contact. Is smooth, and it is difficult for the generated friction and contact surface pressure to be high. That Therefore, damage to wiring and the like is unlikely to occur.
- a step 140a is provided at the end of the input shaft (hollow shaft) 140 to widen the diameter, and the friction reducing bearing 150 is disposed there, so that the inner ring is likely to be contacted. Friction due to the rotation of the hollow shaft without changing the relative position of the inner ring 150b and the wiring, etc., even when the wiring contacts, etc. The force can be practically zero, and wiring can be protected.
- the friction reducing bearing 150 is provided on the second output flange body side of the hollow shaft, but it may be provided on the first output flange body side or on both sides. is there.
- the input shaft is hollow and the wiring is passed therethrough.
- the present invention is not necessarily limited to this, and the hollow shaft is replaced with the first output flange as in the embodiment of FIG. It can also be formed integrally with the body 234.
- a bearing as a friction reducing member is arranged in the protective portion.
- the present invention is not limited to this, and friction such as a fluorine resin sheet can be reduced. It is also possible to arrange the member at the end. In addition to the end, other parts than the end Similarly, it is possible to provide a protective part, but considering the cost, it is most cost-effective to provide it only at the end.
- the embodiment described above is a force that is a power transmission device including an external gear that also swings even when the displacement is not limited to this.
- a high-speed shaft of a simple planetary gear power transmission device Can be applied to the hollow shaft.
- the present invention is used in a technical field where more wiring is required in a complicated machine such as an industrial robot, as well as in a case where it is used as a drive source such as a pump. It can be widely used in fields where the use of is expected.
