Description

本発明は、例えば振動試験装置に用いられる振動発生装置において、所定の振動方向に沿って往復動する可動部を支持する際に好適に用いられる支持装置、および、この支持装置を用いた振動発生装置に関する。 The present invention is, for example, in a vibration generator used in a vibration test device, a support device preferably used when supporting a movable portion that reciprocates along a predetermined vibration direction, and vibration generation using this support device. Regarding the device.

振動試験装置に用いられる振動発生装置においては、いわゆる横揺れを防止して可動部を所定の１軸方向（振動方向）に沿って往復動させることが重要である。横揺れとは、可動部が振動方向に直交する方向（以下、ラジアル方向ということもある）に動くことである。この横揺れを防止するために、振動発生装置では、可動部とその周囲に配置されているヨークなどの固定部との間に支持装置が配置されている。支持装置は、可動部を振動方向へ案内するとともに、ラジアル方向への可動部の動きを規制する。 In the vibration generator used in the vibration test device, it is important to prevent so-called rolling and reciprocate the movable portion along a predetermined uniaxial direction (vibration direction). Rolling means that the moving part moves in a direction orthogonal to the vibration direction (hereinafter, also referred to as a radial direction). In order to prevent this rolling, in the vibration generator, a support device is arranged between the movable portion and a fixed portion such as a yoke arranged around the movable portion. The support device guides the movable part in the vibration direction and regulates the movement of the movable part in the radial direction.

本出願人は、特許文献１において、振動発生装置に用いられる支持装置を提案している。この支持装置は、一対の受け部材および揺動部材から構成されている。一対の受け部材は、振動発生装置の可動部と固定部とにそれぞれ取り付けられる。可動部と固定部に取り付けられた受け部材には、それぞれ一対の平面および一対の傾斜面が設けられている。揺動部材は、可動部と固定部に取り付けられた受け部材に挟まれた状態で保持される。 The applicant proposes a support device used for a vibration generator in Patent Document 1. This support device is composed of a pair of receiving members and a swinging member. The pair of receiving members are attached to the movable portion and the fixed portion of the vibration generator, respectively. The receiving member attached to the movable portion and the fixed portion is provided with a pair of flat surfaces and a pair of inclined surfaces, respectively. The swinging member is held in a state of being sandwiched between a receiving member attached to the movable portion and the fixed portion.

図７は、特許文献１に開示された支持装置を構成する揺動部材３５０を示す図である。図７に示すように、揺動部材３５０は、一対のローラ部３６１，３６２および一対の係合部３７１，３７２を有している。ローラ部３６１，３６２および係合部３７１，３７２は、可動部と固定部にそれぞれに設けられた受け部材の平面および傾斜面に接触するように設けられている。 FIG. 7 is a diagram showing a swing member 350 constituting the support device disclosed in Patent Document 1. As shown in FIG. 7, the swing member 350 has a pair of roller portions 361 and 362 and a pair of engaging portions 371 and 372. The roller portions 361 and 362 and the engaging portions 371 and 372 are provided so as to come into contact with the flat surface and the inclined surface of the receiving member provided on the movable portion and the fixed portion, respectively.

特許第３５３６１４８号公報Japanese Patent No. 3536148

しかしながら、特許文献１の支持装置では、一対の係合部３７１，３７２は、一対のローラ部３６１，３６２によって挟まれるように配置されている。また、一対の係合部３７１，３７２が接触する可動部および固定部の傾斜面は、相互に逆方向に傾斜するように形成されているとともに、相互に隣接して配置されている。このため、振動発生装置の作動中において、揺動部材３５０が偏心モーメントを受けて僅かに傾斜すると、係合部３７１，３７２が接触している傾斜面から外れて本来接触する傾斜面とは異なる隣接する傾斜面に乗り上げてしまう場合があった。 However, in the support device of Patent Document 1, the pair of engaging portions 371 and 372 are arranged so as to be sandwiched by the pair of roller portions 361 and 362. Further, the inclined surfaces of the movable portion and the fixed portion that the pair of engaging portions 371 and 372 come into contact with are formed so as to be inclined in opposite directions and are arranged adjacent to each other. Therefore, if the swing member 350 is slightly tilted due to the eccentric moment during the operation of the vibration generator, the engaging portions 371 and 372 are separated from the contacted tilted surface and are different from the tilted surface that is originally in contact with the swinging member 350. In some cases, it ran on an adjacent slope.

また、ローラ部３６１，３６２が摩耗等した場合には、メンテナンスのためローラ部３６１，３６２を交換する必要があるが、ローラ部３６１，３６２はボルト３５１で組み付けられており、ローラ部３６１，３６２を交換することは容易ではなかった。 Further, when the roller portions 361 and 362 are worn, it is necessary to replace the roller portions 361 and 362 for maintenance. However, the roller portions 361 and 362 are assembled with bolts 351 and the roller portions 361 and 362 are assembled. It was not easy to replace.

本発明は、上記課題に鑑みてなされたものであり、揺動部材が偏心モーメントを受けた場合であっても係合部が隣接する傾斜面に乗り上げることを防止できるとともに、ローラ部の交換が容易であり、メンテナンスのコストを抑制することができる、支持装置および振動発生装置を提供することを目的とする。 The present invention has been made in view of the above problems, and even when the swinging member receives an eccentric moment, it is possible to prevent the engaging portion from riding on an adjacent inclined surface, and the roller portion can be replaced. It is an object of the present invention to provide a support device and a vibration generator which are easy and can reduce the cost of maintenance.

ヨーク１３５は、第１ヨーク部１３５１、第２ヨーク部１３５２、および第３ヨーク部１３５３を一体的に組み合わせて構成されている。第１ヨーク部１３５１、第２ヨーク部１３５２、および第３ヨーク部１３５３は、強磁性体によって形成されている。第１ヨーク部１３５１の外周面と、第２ヨーク部１３５２の内周面との間に磁気ギャップが形成されている。なお、ヨーク１３５を構成する第１ヨーク部１３５１、第２ヨーク部１３５２、および第３ヨーク部１３５３の材質としては、高透磁率で高強度の磁性材料、例えばＳＳ４００等の低炭素鋼を好適に用いることが可能である。 The yoke 135 is configured by integrally combining a first yoke portion 1351, a second yoke portion 1352, and a third yoke portion 1353. The first yoke portion 1351, the second yoke portion 1352, and the third yoke portion 1353 are formed of a ferromagnetic material. A magnetic gap is formed between the outer peripheral surface of the first yoke portion 1351 and the inner peripheral surface of the second yoke portion 1352. As the material of the first yoke portion 1351, the second yoke portion 1352, and the third yoke portion 1353 constituting the yoke 135, a magnetic material having high magnetic permeability and high strength, for example, low carbon steel such as SS400 is preferably used. It can be used.

励磁コイル１３１，１３２は、円筒状に巻回されており、第２ヨーク部１３５２の内周面において振動軸Ｌ１方向に離隔した状態で並んで取り付けられている。励磁コイル１３１，１３２は、第３ヨーク部１３５３と、第１ヨーク部１３５１の外鍔１３５４とによって位置決めされている。 The exciting coils 131 and 132 are wound in a cylindrical shape and are mounted side by side on the inner peripheral surface of the second yoke portion 1352 in a state of being separated in the vibration axis L1 direction. The exciting coils 131 and 132 are positioned by the third yoke portion 1353 and the outer flange 1354 of the first yoke portion 1351.

ドライブコイル１３７は、非磁性体からなる筒体１３９の一端側（図１では、−Ｚ軸方向側）の外周面に巻回されている。ドライブコイル１３７は、励磁コイル１３１，１３２と、ヨーク１３５（第１ヨーク部１３５１、および第２ヨーク部１３５２）との対向間の磁気ギャップ内に、励磁コイル１３１，１３２およびヨーク１３５に対し非接触の状態で挿入されている。なお、筒体１３９の材質としては、非磁性体の高強度の金属（例えばアルミニウム合金）や、合成樹脂（例えばカーボンファイバ）等を好適に用いることが可能である。 The drive coil 137 is wound around an outer peripheral surface of one end side (in the FIG. 1, side in the −Z axis direction) of a tubular body 139 made of a non-magnetic material. The drive coil 137 does not contact the exciting coils 131, 132 and the yoke 135 within the magnetic gap between the exciting coils 131 and 132 and the yokes 135 (first yoke portion 1351 and second yoke portion 1352) facing each other.

Will be generated. A magnetic gap as described above is formed in the yoke 135, and the static magnetic field generated in the magnetic gap is generated by supplying an alternating current of a predetermined frequency to the drive coil 137 arranged in the magnetic gap by the control unit. The drive coil 137 slides in a direction orthogonal to the direction of the magnetic flux due to the force acting between the alternating current supplied to the drive coil 137. In this case, the drive coil 137 and the tubular body 139 slide in the direction of projecting (advancing) outward from the yoke 135 (in the + Z axis direction in FIG. 1) and inward toward the yoke 135 (in FIG. 1). , -Z-axis direction) The slide in the retracting (backward) direction is repeated. That is, the drive coil 137 and the tubular body 139 (moving portion) vibrate along the Z-axis direction with respect to the yoke 135 (fixed portion) at a frequency corresponding to the signal of the alternating current supplied to the drive coil 137.
