【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

この考案は、ホイスト又はクレーン等に用いる走行(転動)音を低減した低騒 音車輪の改良に関する。 The present invention relates to an improvement of a low noise wheel that reduces traveling (rolling) noise used for a hoist or a crane.

【0002】[0002]

【従来の技術】[Prior Art]

従来のクレーン等における車輪部には、図3に例示する如き構造のものがある 。すなわち、ホイール軸1にボールベアリング2を介してトロリーホイール3を 軸着する。トロリーホイール3はレール4上に転接せしめる。トロリーホイール 3の側部にはホイールギヤ5を一体に取り付け、車輪部枠体6に装着したセカン ドピニオン7をホイールギヤ5に噛合させ、セカンドピニオン7を介して駆動力 をトロリーホイール3に伝え、これがレール4上を転動するようにするものであ る。 Some wheel parts of conventional cranes and the like have a structure as illustrated in FIG. That is, the trolley wheel 3 is mounted on the wheel shaft 1 via the ball bearing 2. Roll the trolley wheel 3 onto the rail 4. A wheel gear 5 is integrally attached to a side portion of the trolley wheel 3, a second pinion 7 mounted on a wheel frame 6 is meshed with the wheel gear 5, and a driving force is transmitted to the trolley wheel 3 via the second pinion 7. This allows rolling on the rail 4.

【0003】 上述の如く用いられる従来のトロリーホイール3は全体が鉄製であると、これ がレール4上を転動するときの走行音が極めて大きいので、従来より図4に例示 する如きゴムモールド車輪が用いられていた。これは、鉄製のホイール部8の外 周部にウレタン製の外周部9をモールドして一体に形成したものである。このゴ ムモールド車輪は、ウレタン製の外周部9がレール4上を転動することになり走 行音を低減できるものである。If the conventional trolley wheel 3 used as described above is entirely made of iron, the running noise when it rolls on the rail 4 is extremely large. Therefore, a rubber mold wheel as illustrated in FIG. 4 is conventionally used. Was used. In this, the outer peripheral portion 9 made of urethane is molded integrally with the outer peripheral portion of the wheel portion 8 made of iron. In this rubber mold wheel, the outer peripheral portion 9 made of urethane rolls on the rail 4 so that running noise can be reduced.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

上述のような従来のゴムモールド車輪ではレール4上を転動する際、ゴム製の 外周部9が1個所(線接触)で接触するため、大きな荷重によってゴム製の外周 部9が圧縮されて走行しているうちにゴム製の外周部9が疲労等により割れたり 、ホイール部8から剥がれる等の事故を起こすことがあるという問題があった。 さらに、従来のゴムモールド車輪は、外周部9のゴム部材が1個所(線接触)で レール4に接して荷重を受けるので、その支持荷重が同一輪径の鉄車輪に比べて 小さくなってしまうという問題があった。 In the conventional rubber-molded wheel as described above, when rolling on the rail 4, the rubber outer peripheral portion 9 contacts at one point (line contact), so that the rubber outer peripheral portion 9 is compressed by a large load. There is a problem that the rubber outer peripheral portion 9 may be cracked or peeled off from the wheel portion 8 due to fatigue or the like while traveling. Further, in the conventional rubber-molded wheel, the rubber member of the outer peripheral portion 9 comes into contact with the rail 4 at one position (line contact) and receives a load, so that the supporting load becomes smaller than that of an iron wheel having the same wheel diameter. There was a problem.

【0005】 本考案は上述の点に鑑み、疲労等により破損しないようにした支持荷重の大き な低騒音車輪を新たに提供することを目的とする。The present invention has been made in view of the above points, and an object thereof is to newly provide a low-noise wheel having a large supporting load so as not to be damaged by fatigue or the like.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

本考案の低騒音車輪は、ボスからリムにかけてアームを弾性変形容易なように 架け渡すよう構成し、これらボス、アーム及びリムで囲まれた空間部分に弾性材 料を注入硬化して弾性部を一体に構成したことを特徴とする。 The low noise wheel of the present invention is constructed so that the arm is bridged from the boss to the rim so that it can be easily elastically deformed, and an elastic material is injected into the space surrounded by the boss, the arm and the rim to cure the elastic part. It is characterized by being configured integrally.

【0007】[0007]

【作用】[Action]

上述のように構成することにより、リムに加わる荷重をアームで弾性的に受け てボスに伝えるようにするとともに、弾性部の制振作用によって、この車輪がレ ール上を走行するときの走行(転動)騒音を低減する。また、車輪に大きな力が 加わる場合でも、レール上を転動する金属製リムに加わる荷重をアームが受けて ボスに伝えるので、高耐荷重にできるものである。 With the above-mentioned configuration, the load applied to the rim is elastically received by the arm and transmitted to the boss, and the damping action of the elastic part allows the wheel to travel when traveling on the rail. (Rolling) Reduce noise. In addition, even when a large force is applied to the wheels, the arm receives the load applied to the metal rim rolling on the rail and transmits it to the boss, so that a high withstand load can be achieved.

【実施例】【Example】

以下、本考案の低騒音車輪の一実施例を図1及び図2によって説明する。 An embodiment of the low noise wheel of the present invention will be described below with reference to FIGS.

【0009】 図はトロリーホイール部分を取り出して示すものであり、図で10はボス、1 1はアーム、12はリムである。図示するようにアーム11は、ボス10からそ の接線方向に引き出してリム12に接続するよう構成する。これによりアームを 放射線方向に形成したのに比べて、リム12に加わる荷重をアーム11が弾性的 に受けるようにするものである。なお、このボス10,アーム11及びリム12 は、鋼板を溶断して形成し、又は鋳物成形により製作するものである。The figure shows the trolley wheel portion taken out, and in the figure, 10 is a boss, 11 is an arm, and 12 is a rim. As shown in the drawing, the arm 11 is configured to be pulled out from the boss 10 in the tangential direction thereof and connected to the rim 12. This allows the arm 11 to elastically receive the load applied to the rim 12 as compared with the case where the arm is formed in the radial direction. The boss 10, the arm 11 and the rim 12 are formed by fusing a steel plate or by casting.

【0010】 また本例のトロリーホイールは、図示するようにボス10,アーム11及びリ ム12に囲まれた空間部分を塞ぐようゴム等の弾性材料を注入硬化し弾性部13 を一体に構成する。In the trolley wheel of this example, an elastic material such as rubber is injected and hardened so as to close the space surrounded by the boss 10, the arm 11 and the rim 12 as shown in the figure, and the elastic portion 13 is integrally formed. ..

【0011】 上述の如く構成することにより、アーム11及び弾性部13の弾力性によって 、トロリーホイールがレール上を走行するときの走行(転動)騒音を低減できる 。また、トロリーホイールが大きな荷重を支持する場合でも、リム12に加わっ た荷重をアーム11で支持し、ボス10に伝達するようにするので、トロリーホ イールの外周部にウレタン等をモールドしたものに比べ高耐荷重、長寿命化を図 ることができるものである。With the above-described configuration, the elasticity of the arm 11 and the elastic portion 13 can reduce traveling (rolling) noise when the trolley wheel travels on the rail. Further, even when the trolley wheel supports a large load, the load applied to the rim 12 is supported by the arm 11 and transmitted to the boss 10. Therefore, compared to the trolley wheel molded with urethane or the like on the outer periphery thereof. High load capacity and long life can be achieved.

【0012】 なお、本考案は上述の実施例に限定されるものではなく、本考案の要旨を逸脱 しない範囲内においてその他種々の構成を取り得ることは勿論である。It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.

【0013】[0013]

【考案の効果】[Effect of the device]

以上詳述したように本考案の低騒音車輪によれば、ボスからリムにかけてアー ムを弾性変形容易なように架け渡すよう構成し、これらボス、アーム及びリムで 囲まれた空間部分に弾性材料を注入硬化して弾性部で埋め一体に構成したので、 リムに加わる荷重をアームで弾性的に受けてボスに伝えるようにするとともに、 弾性部の制振作用によって、この車輪がレール上を走行するときの走行(転動) 騒音を低減できるという効果がある。また、車輪に大きな荷重が加わる場合でも 、金属製リムに加わる荷重をアームが受けてボスに伝えるので、ホイール部の外 周部にウレタン等をモールドした従来のものに比べ高耐荷重、長寿命化を図るこ とができるという効果がある。 As described in detail above, according to the low noise wheel of the present invention, the arm is bridged from the boss to the rim so that it can be easily elastically deformed, and the elastic material is provided in the space surrounded by the boss, the arm and the rim. Since it is injected and hardened and filled with the elastic part, it is configured integrally, so that the load applied to the rim is elastically received by the arm and transmitted to the boss, and the vibration damping action of the elastic part causes this wheel to run on the rail. This has the effect of reducing the running (rolling) noise when running. Also, even when a large load is applied to the wheel, the arm receives the load applied to the metal rim and transmits it to the boss. The effect is that it can be realized.
