Description
【０００１】[0001]
本考案は、複数の部材にそれぞれ備えられた歯車を適切な状態で噛み合わせて いる歯車機構に関する。 The present invention relates to a gear mechanism in which gears provided on a plurality of members are meshed with each other in an appropriate state.
【０００２】[0002]
従来、電子機器等の装置を組立てる作業過程において、複数の部材に備えられ た歯車間の噛み合わせは歯車が固定された部材を移動調整して行っていた。図４ は従来の歯車の噛み合い状態を示す平面図であり、図５は従来の歯車の噛み合い 状態を示す正面図である。 2. Description of the Related Art Conventionally, in the process of assembling a device such as an electronic device, meshing between gears provided on a plurality of members is performed by moving and adjusting a member to which gears are fixed. FIG. 4 is a plan view showing a meshing state of a conventional gear, and FIG. 5 is a front view showing a meshing state of a conventional gear.
【０００３】 図４，図５において、装置１の本体２に取付けられたスタッド３の軸部３ａに は歯車４が回転自在に設けられている。また本体２にはネジ５によりモータブラ ケット６が固定されており、このネジ５を緩めることによりモータブラケット６ は移動可能となる。モータブラケット６にはモータ７が固定されており、またモ ータ７の軸７ａにはモータ歯車９が設けられている。モータブラケット６には、 さらにスタッド１０が取付けられており、このスタッド１０の軸部１０ａには歯 車１１が設けられている。歯車４，歯車１１，モータ歯車９は順に噛み合ってお り、つまりモータ７の回転を歯車１１は歯車４に伝達している。In FIGS. 4 and 5, a gear 4 is rotatably provided on a shaft portion 3 a of a stud 3 attached to a main body 2 of the device 1. A motor bracket 6 is fixed to the main body 2 with screws 5, and the motor bracket 6 can be moved by loosening the screws 5. A motor 7 is fixed to the motor bracket 6, and a motor gear 9 is provided on a shaft 7 a of the motor 7. A stud 10 is further attached to the motor bracket 6, and a gear 11 is provided on a shaft portion 10 a of the stud 10. The gear 4, the gear 11, and the motor gear 9 are meshed in order, that is, the rotation of the motor 7 is transmitted to the gear 4 by the gear 11.
【０００４】 次に歯車４及び１１の取付け動作を図４，図５に基づいて説明する。 両図において歯車４を設けたスタッド３を本体２に取付けた後、モータ７を固 定したモータブラケット６をネジ５により本体２に固定する。この時モータ７の 回転を伝える歯車１１と歯車４の噛み合い調整を予め求められている設計値に基 づいて行い、モータブラケット６の位置を定める。Next, the mounting operation of the gears 4 and 11 will be described with reference to FIGS. 4 and 5. In both figures, after the stud 3 provided with the gear 4 is attached to the main body 2, the motor bracket 6 to which the motor 7 is fixed is fixed to the main body 2 with the screw 5. At this time, the engagement between the gear 11 transmitting the rotation of the motor 7 and the gear 4 is adjusted based on a previously designed design value to determine the position of the motor bracket 6.
【０００５】 歯車の歯を噛み合わせる場合、一方の歯車の歯と他方の歯車の歯を噛み合わせ た時に生じる歯面間の遊び（バックラッシ）が適切になるような噛み合い量や、 一方の歯を他方の歯に噛み合わせた時一方の歯の山部と他方の歯の谷部によって 作られる隙間の大きさが予め設計値として与えられており、この設計値に基づい てバックラッシを直接測定して噛み合わせを行っている。When the teeth of a gear are engaged with each other, the amount of engagement such that the play (backlash) between the tooth surfaces generated when the teeth of one gear and the teeth of the other gear are engaged with each other, The size of the gap created by the crests of one tooth and the troughs of the other when meshing with the other tooth is given in advance as a design value, and the backlash is directly measured based on this design value. We are engaged.
【０００６】 そして、ネジ５を緩め、設計値に基づいてモータブラケット６を図の矢印ＡＢ 方向へ調整移動させて歯車４と歯車１１を適切な状態で噛み合わせ、モータブラ ケット６の位置決めを行った後ネジ５を締めて取付けを終了する。Then, the screw 5 is loosened, the motor bracket 6 is adjusted and moved in the direction of arrow AB in the drawing based on the design value, the gear 4 and the gear 11 are meshed in an appropriate state, and the motor bracket 6 is positioned. Tighten the rear screw 5 to finish the installation.
【０００７】[0007]
しかしながら、上記調整方法では歯車の歯の噛み合い量や一方の歯の山部と他 方の歯の谷部とで作られる隙間が微小な場合、噛み合わせの精密な調整は困難で 時間がかかり、その結果調整の作業性が悪くなるという問題が起こっていた。 However, with the above adjustment method, if the amount of meshing of the gear teeth and the gap created by the crests of one tooth and the troughs of the other tooth are very small, precise adjustment of the meshing is difficult and time consuming. As a result, there has been a problem that the workability of adjustment is deteriorated.
【０００８】 本考案は、以上述べた問題点を除去するために、噛み合う歯車の軸間にそれぞ れの軸が嵌入する孔を持ったプレートを架け渡すことにより、歯車の噛み合わせ を正確に行う調整作業性の優れた歯車機構を提供することを目的とする。In order to eliminate the above-mentioned problems, the present invention provides accurate gear meshing by interposing a plate having holes into which the respective gears are fitted between the meshing gear shafts. It is an object of the present invention to provide a gear mechanism with excellent workability for adjustment.
【０００９】[0009]
前記課題を解決するために本考案は、複数の部材にそれぞれ歯車を備え、各歯 車を噛み合わせて取付ける歯車機構において、歯車の軸がそれぞれ嵌入する孔を 有し、孔間の距離が前記歯車の噛み合いが適切となる軸間の距離であるプレート を設けたものである。 In order to solve the above problems, the present invention provides a gear mechanism in which a plurality of members are respectively provided with gears and gears are engaged with each other by gears, and each of the gear shafts has a hole into which the gear shaft is fitted. It is provided with a plate that is the distance between the shafts where the meshing of the gears is appropriate.
【００１０】[0010]
複数の歯車の軸間に歯車の軸がそれぞれ嵌入する孔が形成されたプレートを架 け渡す。これにより歯車の歯と歯の噛み合わせが適切な状態となる距離に軸が位 置付けられる。それ故歯車の噛み合い調整の作業が不要となる。 A plate is formed between the shafts of the plurality of gears, each plate having a hole into which the shaft of the gear is fitted. This positions the shaft at a distance such that the teeth of the gears are in proper meshing. Therefore, the work of adjusting the meshing of gears is unnecessary.

【実施例】 以下に本考案の実施例について図面を参照しながら詳細に説明する。なお各図 面に共通する要素には同一の符号を付す。 図１は本考案に係る一実施例の歯車の噛み合いを示す平面図であり、図２はこ の一実施例の歯車の噛み合いを示す正面図である。また、図３は、この一実施例 のプレートを示す斜視図である。Embodiments of the present invention will be described below in detail with reference to the drawings. The elements common to all the drawings are given the same reference numerals. 1 is a plan view showing the meshing of a gear according to an embodiment of the present invention, and FIG. 2 is a front view showing the meshing of a gear according to the embodiment. Further, FIG. 3 is a perspective view showing the plate of this embodiment.
【００１２】 図１，図２，図３において、本実施例の装置２０の軸部３ａ，軸部１０ａ間に はプレート２１が架け渡されており、このプレート２１には図３で示すように２ 個の孔２１ａ，２１ｂが形成されている。これらの孔２１ａ，２１ｂ間の距離Ｌ は高精度に造られており、歯車４，歯車１１の軸部３ａ，１０ａを孔２１ａ，２ １ｂに嵌入させた時、歯車４，１１の噛み合わせは適切な状態となる距離になっ ている。故に図１，図２の状態において、歯車４，１１は適切な状態で噛み合う 。その他の構造については従来技術と同様である。In FIGS. 1, 2 and 3, a plate 21 is bridged between the shaft portion 3 a and the shaft portion 10 a of the device 20 of this embodiment, and as shown in FIG. Two holes 21a and 21b are formed. The distance L between the holes 21a and 21b is made with high precision, and when the shaft portions 3a and 10a of the gear 4 and the gear 11 are fitted into the holes 21a and 21b, the meshing of the gears 4 and 11 does not occur. The distance is appropriate. Therefore, in the state shown in FIGS. 1 and 2, the gears 4 and 11 mesh with each other in an appropriate state. Other structures are similar to those of the conventional art.
【００１３】 次に歯車４，１１の取付けにおける動作を説明する。 先ず歯車４を回転自在に設けた軸部３ａのスタッド３を本体２に取付ける。次 にモータブラケット６に固定されたモータ７の軸７ａにモータ歯車９を設け、さ らにモータブラケット６に取付けたスタッド１０の軸部１０ａに設けた歯車１１ にこのモータ歯車９を噛み合わせる。Next, the operation of mounting the gears 4 and 11 will be described. First, the stud 3 of the shaft portion 3a provided with the gear 4 rotatably attached is attached to the main body 2. Next, the motor gear 9 is provided on the shaft 7a of the motor 7 fixed to the motor bracket 6, and the motor gear 9 is meshed with the gear 11 provided on the shaft portion 10a of the stud 10 attached to the motor bracket 6.
【００１４】 そして、歯車４，１１の軸部３ａ，１０ａをプレート２１の２つの孔２１ａ， ２１ｂにそれぞれ合わせて嵌入させる。軸部３ａ，１０ａを孔２１ａ，２１ｂに 嵌入させることにより、精度よく歯車４，１１は適切な状態で噛み合う。この後 ネジ５によりモータブラケット６を本体２に固定すると、図１，図２に示す状態 になる。Then, the shaft portions 3a and 10a of the gears 4 and 11 are fitted into the two holes 21a and 21b of the plate 21, respectively. By fitting the shaft portions 3a and 10a into the holes 21a and 21b, the gears 4 and 11 are accurately meshed in an appropriate state. After that, when the motor bracket 6 is fixed to the main body 2 with the screw 5, the state shown in FIGS. 1 and 2 is obtained.
【００１５】[0015]
以上詳細に説明したように、本考案によれば、噛み合う歯車の軸間にそれぞれ の軸を嵌入させる孔が形成されたプレートを架け渡すことにより、歯車の噛み合 いが適切な状態となるので、設計値に基づく調整作業が不要となる。この結果装 置の組立てに要する作業時間が短縮される。またこのプレートは、装置使用中の モータブラケットのたわみにより発生する歯車軸の傾きを防止する軸補強材とし ての働きもある。 As described in detail above, according to the present invention, the meshing of the gears is brought into an appropriate state by bridging the plates formed with the holes for fitting the respective shafts between the meshing gears. No need for adjustment work based on design values. As a result, the work time required to assemble the device is shortened. This plate also functions as a shaft reinforcement that prevents the gear shaft from tilting due to the bending of the motor bracket during use of the device.
