この考案は、ローラ，プーリ，歯車等の回転体をその支持軸に取り付ける回転 体の取付構造に関する。 This device is a rotating body that attaches rotating bodies such as rollers, pulleys, gears, etc. to their support shafts. Regarding the body attachment structure.
【０００２】0002
前記回転体をその支持軸に対して、回転方向に一体となるように取り付ける構 造としては、図５や図６に示すものが知られている。図５に示す構造は、回転体 としてのプーリ６０に取付用ボス６１を形成し、支持軸６２の段部６３にボス６ １の一端面を衝合させて軸方向の位置決めをしたのち、ボス部６１に螺合させた 固定用ねじ（いもねじ）６４を小径部６５の周面に突き当てることで回転方向を 一体化させたものである。 A structure in which the rotating body is mounted integrally with respect to its support shaft in the rotational direction. The structures shown in FIGS. 5 and 6 are known. The structure shown in Figure 5 is a rotating body A mounting boss 61 is formed on the pulley 60, and a boss 6 is formed on the stepped portion 63 of the support shaft 62. After positioning in the axial direction by aligning one end surface of 1, the screw is screwed into the boss part 61 The direction of rotation can be determined by abutting the fixing screw (potato screw) 64 against the circumferential surface of the small diameter portion 65. It is integrated.
【０００３】 図６に示す構造は、支持軸７０に段部７１をおいて小径部７２を形成し、この 小径部７２の周面の一部を殺ぎ落して断面Ｄ形とし、プーリ７３の嵌合孔７４を Ｄ形に形成してこれを小径部７２に嵌挿したのち、小径部に形成した周溝７５に 止め輪７６を係合させて軸方向を位置決めして取り付けるものである。0003 In the structure shown in FIG. 6, a step portion 71 is provided on a support shaft 70 to form a small diameter portion 72. A part of the circumferential surface of the small diameter portion 72 is cut off to form a D-shaped cross section, and the fitting hole 74 of the pulley 73 is formed. After forming it into a D shape and inserting it into the small diameter part 72, it is inserted into the circumferential groove 75 formed in the small diameter part. The retaining ring 76 is engaged to position the retaining ring 76 in the axial direction.
【０００４】0004
図５に示す構造は、ねじの締め付け作業が煩わしいという問題に加えて、取付 用ボス６１を設けた分だけ回転体６０の軸方向長さが長くなり、軸方向における スペースを小さくすることが要求される機構においては不利な構造である。ねじ による固定は、締め付けトルクを管理しないと緩みによる不具合の発生が懸念さ れると共に回転体交換時の作業性が悪いという問題がある。図６に示す構造は、 軸方向におけるスペースの問題はないが、Ｄ形の軸部７２と孔７４との間に寸法 誤差があると、完全固定とならず、支持軸７０と回転体７３との間に回転方向の 「がた」が生じるという問題がある。 The structure shown in Figure 5 has the problem that the screw tightening work is troublesome, and the installation The axial length of the rotating body 60 is increased by the provision of the service boss 61. This is a disadvantageous structure in a mechanism that requires a small space. screw If the tightening torque is not controlled, problems may occur due to loosening. In addition, there is a problem that the workability when replacing the rotating body is poor. The structure shown in FIG. There is no problem with the space in the axial direction, but the dimension between the D-shaped shaft portion 72 and the hole 74 is If there is an error, it will not be completely fixed, and there will be a problem in the rotational direction between the support shaft 70 and the rotating body 73. There is a problem that "backlash" occurs.
【０００５】 図５と図６に示す構造の折衷案として、 図５に示す固定ねじ６４を、図６ （ ｂ）に示すプーリ７３にボス部を形成することなく螺合することも考えられるが 、搬送用ローラの周面、タイミングベルトを巻き掛けられるタイミングプーリの 歯、互いに噛み合う歯車の歯部のような回転体の作用面にねじ用の孔が存在する ことは、精密な作動を要求される機構においては許されない。また、小型の機器 における回転体は、必然的に小径のねじを用いることになるので、締め付け時に ねじ山が潰れ易いという問題もある。[0005] As a compromise between the structures shown in FIGS. 5 and 6, the fixing screw 64 shown in FIG. Although it is conceivable that the pulley 73 shown in b) may be screwed into the pulley 73 without forming a boss portion. , the circumferential surface of the conveyor roller, and the timing pulley around which the timing belt is wrapped. A hole for a screw exists on the working surface of a rotating body, such as the teeth of gears that mesh with each other. This cannot be allowed in a mechanism that requires precise operation. Also, small equipment Since the rotating body inevitably uses small-diameter screws, it is difficult to tighten them when tightening. There is also the problem that the threads are easily crushed.
【０００６】 そこで、本考案の目的は、軸方向におけるスペースを確保できると共にねじに よる不具合を解消した回転体の取付構造の提供にある。[0006] Therefore, the purpose of this invention is to secure space in the axial direction and to An object of the present invention is to provide a mounting structure for a rotating body that eliminates the problems caused by such problems.

【０００９】[0009]
以下、図示の実施例に基づいて本考案を詳細に説明する。 Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.
【００１０】 図１において、支持軸１の端部には、位置決め用の係合ピン２が挿通されてい る。図示の例では、係合ピン２はその両端部２ａ，２ｂを軸周面から突出させて 設けてある。支持軸１には、係合ピン２と所定の間隔を置いて周溝３が形成され ている。周溝３には、止め輪としてのＥリング４が係合される。0010 In FIG. 1, an engagement pin 2 for positioning is inserted into the end of the support shaft 1. Ru. In the illustrated example, the engagement pin 2 has both ends 2a and 2b protruding from the shaft peripheral surface. It is provided. A circumferential groove 3 is formed in the support shaft 1 at a predetermined distance from the engagement pin 2. ing. An E ring 4 serving as a retaining ring is engaged with the circumferential groove 3.
【００１１】 回転体としてのプーリ５には支持軸１に嵌挿される孔５ａが形成されている。 係合ピン２に対向するプーリ５の一端面５ｂには、ピンの突出端部２ａ，２ｂが 係合する係合部６ａ，６ｂからなる第１係合部６が形成されている。この第１係 合部６は、係合ピン２に対して比較的密に係合する幅に形成されている。係合部 の底部６ｃと他端面５ｃとの間は厚さｔ１に形成されている。従って、係合ピン ２と周溝３の所定の間隔とは、プーリ５の厚さｔ１に相当するものである。[0011] A hole 5a into which the support shaft 1 is inserted is formed in the pulley 5 as a rotating body. One end surface 5b of the pulley 5 facing the engagement pin 2 has projecting ends 2a and 2b of the pin. A first engaging portion 6 is formed which includes engaging portions 6a and 6b that engage with each other. This first section The mating portion 6 is formed to have a width that allows it to engage the engagement pin 2 relatively closely. Engagement part A thickness t1 is formed between the bottom portion 6c and the other end surface 5c. Therefore, the engagement pin 2 and the predetermined interval between the circumferential groove 3 corresponds to the thickness t1 of the pulley 5.
【００１２】 そして、図２（ｂ）に示すように、第１係合部６の底部６ｃが係合ピン２に当 接して係合する位置まで、プーリ５を支持軸１に嵌挿したのち周溝３にＥリング ４を係合させる。これでプーリ５は支持軸１に回転方向と軸方向とをそれぞれ一 体化されて取り付けられたことになる。0012 Then, as shown in FIG. 2(b), the bottom part 6c of the first engaging part 6 comes into contact with the engaging pin 2. After inserting the pulley 5 into the support shaft 1 until it touches and engages, insert the E-ring into the circumferential groove 3. 4. The pulley 5 is now aligned with the support shaft 1 in both the rotational direction and the axial direction. It has been embodied and installed.
【００１３】 支持軸１が回転駆動されると、図２（ａ）に示すように、係合ピン２の回転方 向における前後方向側面２ｃ，２ｄが軸の回転方向に応じて第１係合部６ａ，６ ｂの対向側面に係合する。この実施例の場合、係合ピン２は、第１係合部６に対 する遊動角度が零であって両者は同一個所で常時係合している。従って、図２（ ａ）に示すような取付態様は、軸と回転体との間に回転方向の遊びを許されない 場合に適している。[0013] When the support shaft 1 is rotationally driven, the engagement pin 2 rotates as shown in FIG. 2(a). The front and rear side surfaces 2c and 2d in the direction are the first engaging portions 6a and 6 depending on the rotational direction of the shaft. engages with the opposite side surface of b. In this embodiment, the engagement pin 2 is connected to the first engagement portion 6. The free movement angle is zero, and both are always engaged at the same location. Therefore, Fig. 2 ( In the installation mode shown in a), no play in the rotational direction is allowed between the shaft and the rotating body. suitable for cases.
【００１４】 ところで、回転体と支持軸が回転方向において、遊びをもって取り付けられる 場合がある。例えば、カードリーダなどにおいて、一方向に取り込んだカードを 直ちに逆方向に送り戻しながらリード・ライトする作動がある。この場合、送り ローラや、これを駆動するタイミングベルトプーリは、正逆回転変換時のモータ が定速になるまでの立上りの時間中は回転が一定しない。リード・ライトは、カ ードを定速で送りながら実行するので、モータ（回転体）の立上り時間を稼ぐた めにカードの走行通路を長くする必要がある。立ち上がったモータで駆動される 回転体が直ちに定速で回転させられるなら、走行通路を短縮することができ機構 を小嵩化できる。これを実現できる例を説明する。[0014] By the way, the rotating body and the support shaft are attached with some play in the direction of rotation. There are cases. For example, when using a card reader, etc., cards read in one direction can be There is a read/write operation that immediately sends data back in the opposite direction. In this case, the feed The rollers and the timing belt pulley that drives them are the motors used when converting forward/reverse rotation. The rotation is not constant during the rising time until the speed reaches a constant speed. Read/write is Since the command is executed while feeding at a constant speed, the motor (rotating body) has more startup time. Therefore, it is necessary to lengthen the card travel path. driven by a raised motor If the rotating body can be rotated immediately at a constant speed, the traveling path can be shortened and the mechanism can be made smaller. An example in which this can be achieved will be explained.
【００１５】 図１及び図３に示すように、プーリ５には、第１係合部６に直交する向きに第 ２係合部７が形成されている。 この第２係合部７は、係合ピン２の突出端部２ ａ，２ｂに係合する係合部７ａ，７ｂとからなっている。各係合部７ａ，７ｂの 回転方向における側面７ｃ，７ｄは、これに係合された係合ピン２が或る程度の 角度αをもって遊動し得るような角度で形成されている。[0015] As shown in FIG. 1 and FIG. Two engaging portions 7 are formed. This second engaging portion 7 is a protruding end portion 2 of the engaging pin 2. It consists of engaging parts 7a and 7b that engage with parts a and 2b. of each engaging portion 7a, 7b. The side surfaces 7c and 7d in the rotational direction are such that the engagement pin 2 engaged therewith has a certain degree of It is formed at an angle that allows it to move freely at an angle α.
【００１６】 第２係合部７の深さは第１係合部６よりも深く形成されている。すなわち、底 部７ｅから他端面５ｃまでのプーリ５の厚さｔ２は、第１係合部６を形成された 部分の厚さｔ１（図２（ｂ）参照）よりも大きく形成されている。従って、かか るプーリを取り付け等れる支持軸１Ａにおける係合ピン２から周溝３Ａまでの間 隔は、厚さｔ２に合わせて形成される[0016] The second engaging portion 7 is formed deeper than the first engaging portion 6. i.e. the bottom The thickness t2 of the pulley 5 from the portion 7e to the other end surface 5c is the same as the thickness t2 of the pulley 5 when the first engaging portion 6 is formed. It is formed to be larger than the thickness t1 of the portion (see FIG. 2(b)). Therefore, whether The area between the engagement pin 2 and the circumferential groove 3A on the support shaft 1A to which the pulley is attached. The gap is formed to match the thickness t2.
【００１７】 そして、図３（ｂ）に示すように、第２係合部７を係合ピン２に係合させて支 持軸１Ａにプーリ５を嵌挿したのち、周溝３ＡにＥリング４を係合させると、取 り付けが完了する。このように取り付けたプーリ５は、支持軸１Ａが正逆回転す るときには、図３（ａ）に示すように、係合部７内において係合ピン２が角度α だけ遊動したのち軸の回転を伝達される。例えば、支持軸１Ａが反時計方向に正 回転するとき、プーリ５は、第２係合部の側面７ｄ，７ｄを係合ピン２の側面２ ｄ，２ｄで押動されることによって回転させられる。 支持軸１Ａが逆転される と、プーリ５は、支持軸の係合ピン２が角度αだけ遊動したのち係合する側面７ ｃ，７ｃをピンの側面２ｃ，２ｃで押動されて逆転させられる。角度αは駆動モ ータすなわち支持軸１Ａが定速になるまでの時間を考慮して設定されている。従 って、逆転されるプーリ５は、略定速で回転を開始することになる。[0017] Then, as shown in FIG. 3(b), the second engaging portion 7 is engaged with the engaging pin 2 for support. After inserting the pulley 5 into the holding shaft 1A, when the E-ring 4 is engaged with the circumferential groove 3A, the removal is completed. installation is complete. The pulley 5 installed in this way allows the support shaft 1A to rotate in forward and reverse directions. As shown in FIG. 3(a), when the engagement pin 2 is at an angle α After that, the rotation of the shaft is transmitted. For example, if the support shaft 1A is rotated counterclockwise, When rotating, the pulley 5 connects the side surfaces 7d of the second engaging portion to the side surface 2 of the engaging pin 2. It is rotated by being pushed at points d and 2d. Support shaft 1A is reversed Then, the pulley 5 engages the side surface 7 after the engagement pin 2 of the support shaft moves by an angle α. c, 7c are pushed by the side surfaces 2c, 2c of the pin and reversed. The angle α is the drive motor It is set in consideration of the time it takes for the motor, that is, the support shaft 1A, to reach a constant speed. subordinate Therefore, the pulley 5 that is reversed starts rotating at a substantially constant speed.
【００１８】 図１に示すように、複数の係合部６，７を形成すると、図２に示す完全固定と 図３に示す半固定（遊動可能）のように、異なる回転伝達方式で回転される回転 体を一つの回転体で兼ねることができ、部品の共通化による部品点数削減とその 管理が容易となる。また、回転方向における回転体の厚さを変えると共にこれに 応じて係合ピンと周溝との間隔を変えると、厚さと間隔の関係から間違った回転 体を取り付ける組立ミスがなくなる。[0018] As shown in FIG. 1, forming a plurality of engaging portions 6 and 7 results in complete fixation as shown in FIG. Rotation that is rotated by different rotation transmission methods, such as semi-fixed (free movement) shown in Figure 3 The body can be used as a single rotating body, reducing the number of parts and reducing the number of parts by standardizing parts. Management becomes easier. In addition, by changing the thickness of the rotating body in the direction of rotation, If you change the distance between the engagement pin and the circumferential groove accordingly, incorrect rotation may occur due to the relationship between the thickness and the distance. Eliminates assembly errors when attaching the body.
【００１９】 また、図示の実施例における第１・第２係合部６，７は、孔５ａを中心として 対称位置に係合部６ａ，６ｂ及び同７ａ，７ｂを形成し、これらに係合する係合 ピン２はその両端部２ａ，２ｂを軸周面から突出させたので、回転伝達のバラン スが良い。但し、精密な回転伝達を要求されない回転体の場合には、一方の係合 部６ａ，７ａだけを有する係合部の構造であっても良い。この場合、係合ピン２ は、その一端のみを軸周面から突出させられれば足りる。なお、図１に示す実施 例においては、各係合部が抜止め機能を果たすので、係合ピン２を支持軸１に圧 入する必要はない。[0019] In addition, the first and second engaging portions 6 and 7 in the illustrated embodiment are centered around the hole 5a. Engagement parts 6a, 6b and 7a, 7b are formed at symmetrical positions, and an engagement part that engages with these parts is formed. Since the pin 2 has both ends 2a and 2b protruding from the shaft peripheral surface, the balance of rotation transmission is improved. It's good. However, in the case of a rotating body that does not require precise rotation transmission, one engagement The structure of the engaging portion may include only the portions 6a and 7a. In this case, engaging pin 2 It is sufficient if only one end of the shaft protrudes from the shaft peripheral surface. Note that the implementation shown in Figure 1 In the example, since each engaging part performs a retaining function, the engaging pin 2 is pressed against the support shaft 1. There is no need to enter.
【００２０】 図１に示す実施例は、係合部６，７を凹部で形成したので、軸方向における取 付スペースが小さくて済み、 しかもねじを用いないので緩みが発生しない。ま た、ローラのような回転体は、周面が摩耗すると交換する必要があるも、本考案 は止め輪の脱着だけで回転体の交換ができて作業性が良い。[0020] In the embodiment shown in FIG. 1, since the engaging portions 6 and 7 are formed with concave portions, they can be easily removed in the axial direction. It requires less installation space, and since no screws are used, there is no possibility of loosening. Ma In addition, rotating bodies such as rollers need to be replaced when their peripheral surfaces wear out, but this invention The rotating body can be replaced simply by attaching and detaching the retaining ring, making it easy to work.
【００２１】 次に、取付スペースをあまり問題にしない場合の実施例を図４で説明する。こ の実施例において、プーリ５の一端面５ｂには軸方向に突出させた突部９が形成 されている。この突部９には、軸線対称に第１係合部１６と第２係合部１７が形 成されている。第１係合部１６の深さは、第２係合部１７のそれよりも深く形成 されている。各係合部に係合する係合ピン１２は、支持軸１に圧入されている。 図４に示す突部９の突起９ａ，９ｂはこれをピン形状に形成しても良い。[0021] Next, an embodiment in which the mounting space is not a problem will be described with reference to FIG. 4. child In the embodiment, a protrusion 9 that protrudes in the axial direction is formed on one end surface 5b of the pulley 5. has been done. This protrusion 9 has a first engaging portion 16 and a second engaging portion 17 formed symmetrically along the axis. has been completed. The depth of the first engaging part 16 is formed deeper than that of the second engaging part 17. has been done. An engagement pin 12 that engages with each engagement portion is press-fitted into the support shaft 1. The protrusions 9a and 9b of the protrusion 9 shown in FIG. 4 may be formed into pin shapes.
【００２２】 かかる構造のプーリ５を支軸１に脱着する手順は図１に示す例と同じである。 そして、この例においても、ねじの緩みの問題は生ぜず、作業の容易性や部品管 理の利便性という効果を奏する。[0022] The procedure for attaching and detaching the pulley 5 having such a structure to the support shaft 1 is the same as the example shown in FIG. In this example as well, there is no problem with the screws coming loose, and the ease of work and parts pipes are improved. This has the effect of providing convenience for people.
【００２３】[0023]
以上のように、本考案によれば、ねじを不要にして回転体を取り付けるので、 取付後の緩みがなくなり、組立性が大きく向上する。また、軸方向の取付スペー スが小さくて済む。更に、係合ピンと止め輪で挾持される部分の回転体厚さを変 えることで部品の共通化が実現できる。 As described above, according to the present invention, since the rotating body is attached without the need for screws, No looseness after installation, greatly improving ease of assembly. Also, the mounting space in the axial direction The space can be small. Furthermore, the thickness of the rotating body at the part held by the engagement pin and retaining ring can be changed. By doing so, it is possible to standardize parts.
