Description
【０００１】[0001]
本考案は、ローラコンベヤのローラ軸を保持する軸受の取付構造に関する。 The present invention relates to a bearing mounting structure for holding a roller shaft of a roller conveyor.
【０００２】[0002]
周知のように丸ベルトローラコンベヤなどのローラコンベヤは、溝付のアルミ ニュームフレームを用い、キャリアローラの軸は前記フレームの溝に取付けた合 成樹脂製の軸受ホルダーに保持させている。前記軸受ホルダーはＵ字形の落し込 み溝を有する受部本体と、この後側に一体に形成された固定部とからなり、この 固定部をフレームの溝に挿入しボルトで固定する構造となっている。 As is well known, a roller conveyor such as a round belt roller conveyor uses an aluminum frame with a groove, and the shaft of the carrier roller is held by a bearing holder made of synthetic resin mounted in the groove of the frame. The bearing holder is composed of a receiving part main body having a U-shaped recessed groove and a fixing part integrally formed on the rear side thereof, and the fixing part is inserted into the groove of the frame and fixed with bolts. ing.
【０００３】[0003]
ところで前記軸受ホルダーは合成樹脂製であるため、樹脂が吸湿し締付けトル クが変動することがある。締付けトルクが変動して締付け力が低下すると、ホル ダーに外力が加わるとホルダーが横移動し、ローラ間隔がズレたり、駆動ベルト の回転力がローラにうまく伝わらず円滑な搬送ができないなどの問題点がある。 Since the bearing holder is made of synthetic resin, the resin may absorb moisture and the tightening torque may change. When the tightening torque fluctuates and the tightening force decreases, the holder moves laterally when an external force is applied to the holder, the gap between the rollers shifts, and the rotational force of the drive belt is not well transmitted to the rollers, which prevents smooth conveyance. There is a point.
【０００４】 本考案は前記従来形の軸受ホルダーの難点を排除するためになされたものでそ の目的とするところは構造簡単にして、締付けトルクが高く、湿気、水分などに 影響をうけることがない軸受ホルダーの取付構造を提供することにある。The present invention has been made to eliminate the drawbacks of the conventional bearing holders. The purpose of the present invention is to simplify the structure and to have a high tightening torque, which can be affected by moisture, moisture, etc. Not to provide a bearing holder mounting structure.
【０００５】[0005]
前記目的を達成するため本考案は、Ｕ字型のシャフト落し込み溝を有する受部 本体と、この後側に一体に形成された固定部とからなり、前記固定部をフレーム に設けた取付溝に挿入し、固定部に設けたネジ孔にネジを螺合させ、固定部とネ ジヘッドで取付溝の壁を挟持させる軸受ホルダーの取付構造であって、前記ホル ダーを亜鉛合金ダイカストで一体に成型すると共に、固定部にはフレームの溝に 挿入したとき溝壁内側に当接する箇所及びネジヘッドの下面にそれぞれ凹凸面を 形成したものである。 In order to achieve the above object, the present invention comprises a receiving part body having a U-shaped shaft drop groove and a fixing part integrally formed on the rear side of the receiving part body. The fixing part is provided on a frame. The mounting structure of the bearing holder is to insert the screw into the screw hole provided in the fixed part and sandwich the wall of the mounting groove between the fixed part and the screw head.The holder is integrated with the zinc alloy die casting. In addition to being molded, the fixed part is provided with uneven surfaces on the bottom surface of the screw head and the part that contacts the inside of the groove wall when inserted into the groove of the frame.
【０００６】 本考案は前記の構成であるから、締付けトルクが高く、コンベヤ駆動時の振動 などによる緩みが生じることがない。Since the present invention has the above-mentioned configuration, the tightening torque is high, and the loosening due to the vibration when the conveyor is driven does not occur.
【０００７】[0007]
以下図示の実施例に基づき本考案を具体的に説明する。 図１は本考案の一実施例による軸受ホルダーを取付けたコンベヤの一部を示す平 面図で、図中符号１が軸受ホルダー、２は締付けボルト、３はコンベヤフレーム である。 The present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a plan view showing a part of a conveyor to which a bearing holder according to an embodiment of the present invention is attached. In the figure, reference numeral 1 is a bearing holder, 2 is a fastening bolt, and 3 is a conveyor frame.
【０００８】 軸受ホルダー１は、受部本体４と固定部５から構成され、これらを亜鉛合金ダ イカストによって一体成型したものである。受部本体４は溝壁６によって形成し たＵ字形のシャフト落し込み溝７を有し、この溝７の下端側の両面にはシャフト に設けたスリットと嵌合する抜け止め用凸部８が設けられている。The bearing holder 1 is composed of a receiving portion main body 4 and a fixing portion 5, and these are integrally molded by zinc alloy die casting. The receiving part main body 4 has a U-shaped shaft drop-in groove 7 formed by a groove wall 6, and on both surfaces at the lower end side of this groove 7, there is a retaining projection 8 that fits with a slit provided in the shaft. It is provided.
【０００９】 固定部５は、前記受部本体４の後側に形成されている。すなわち図２に示すよ うに受部本体４の溝壁６の後面側中央部に、コンベヤフレーム３に設けた取付溝 ３ａの開口部３ｂの高さよりわずかに低い高さの連設部９を設け、この連設部９ に固定部５が一体に配設されている。固定部５は受部本体４よりも幅広のプレー ト状で側端の一方は受部本体４の側端面と面一、高さは受部本体とほぼ同一で、 前面側の上下は前記連設部９と同一面を形成するように切り欠かれれている。そ してこの切り欠き部分の垂直面には鋸歯状の凹凸面１０が形成されている。また 固定部５には締付ボルト２挿入用のネジ孔１１を穿設している。The fixed portion 5 is formed on the rear side of the receiving portion main body 4. That is, as shown in FIG. 2, a continuous portion 9 having a height slightly lower than the height of the opening 3b of the mounting groove 3a provided in the conveyor frame 3 is provided in the center of the rear surface side of the groove wall 6 of the receiving portion main body 4. The fixed portion 5 is integrally arranged with the continuous portion 9. The fixed part 5 is wider than the receiving part main body 4, and one side end is flush with the side end surface of the receiving part main body 4, the height is almost the same as the receiving part main body, and the upper and lower sides on the front side are the above-mentioned connecting parts. It is notched so as to form the same surface as the installation portion 9. A saw-toothed concavo-convex surface 10 is formed on the vertical surface of the cutout portion. Further, the fixing portion 5 is provided with a screw hole 11 for inserting the tightening bolt 2.
【００１０】 締付けボルト２は、軸受ホルダー１のネジ孔１１に螺合させるもので、ボルト ヘッド２ａの下面には図３に示すように放射状の凹凸面２ｂが形成されており、 この凹凸面２ｂとホルダー固定部５の凹凸面１０でフレーム３の取付溝３ａの壁 ３ｃを狭持する。The tightening bolt 2 is screwed into the screw hole 11 of the bearing holder 1, and a radial uneven surface 2b is formed on the lower surface of the bolt head 2a as shown in FIG. 3, and the uneven surface 2b is formed. And the wall 3c of the mounting groove 3a of the frame 3 is sandwiched by the uneven surface 10 of the holder fixing portion 5.
【００１１】 前記構造の軸受ホルダー１をフレーム３に取り付けるには、ホルダー１をフレ ーム３に設けた取付け溝３ａの端部から図４に示すように固定部５が溝３ａ内に 受部本体４が溝外に位置するようにして挿入する。そして所定位置において固定 部５に設けたネジ孔１１に締付けボルト２を螺合して締付ける。前記ボルト２の 締付けによりボルトヘッド２ａの下面に設けた凹凸面２ｂと、ホルダー１の固定 部５に設けた凹凸面１０とによってフレーム３に設けた取付け溝３ａの溝壁３ｃ を狭持し、ホルダー１が所定位置に固定される。所定位置に固定された軸受ホル ダー１のシャフト落とし込み溝７には図１及び図４に示すように、コンベヤのロ ーラ２０のシャフト２１を落とし込み、シャフト２１に設けたスリット２２と落 とし込み溝７に設けた凸部８とを嵌合させてシャフト２１を溝７内に保持させる 。In order to mount the bearing holder 1 having the above structure on the frame 3, the fixing portion 5 is received in the groove 3a from the end of the mounting groove 3a provided on the frame 3 as shown in FIG. Insert so that the main body 4 is located outside the groove. Then, at a predetermined position, the tightening bolt 2 is screwed into the screw hole 11 provided in the fixing portion 5 and tightened. By tightening the bolt 2, the uneven surface 2b provided on the lower surface of the bolt head 2a and the uneven surface 10 provided on the fixing portion 5 of the holder 1 hold the groove wall 3c of the mounting groove 3a provided on the frame 3, The holder 1 is fixed in place. As shown in FIGS. 1 and 4, the shaft 21 of the roller 20 of the conveyor is dropped into the shaft drop groove 7 of the bearing holder 1 fixed at a predetermined position, and the slit 22 provided on the shaft 21 and the drop 22. The shaft 21 is held in the groove 7 by fitting with the convex portion 8 provided in the groove 7.
【００１２】 本実施例の取付構造は前記のように軸受けホルダーを亜鉛合金ダイカスト製の 一体成型としたので、吸湿することがなく、吸湿に伴う締付けトルクの低下がな い。また固定部と締付けボルトのヘッド下面に凹凸面を形成し、該部分で取付け 溝の溝壁を狭持するので締付けトルクが高まる。In the mounting structure of this embodiment, since the bearing holder is integrally formed of zinc alloy die casting as described above, it does not absorb moisture and the tightening torque does not decrease due to moisture absorption. Further, since the uneven surface is formed on the fixing portion and the lower surface of the head of the tightening bolt, and the groove wall of the mounting groove is sandwiched at this portion, the tightening torque is increased.
【００１３】 なお本考案は前記実施例に限定されるものではなく、考案の趣旨を変更しない 限度において種々の修正、設計変更が可能であることはいうまでもない。It is needless to say that the present invention is not limited to the above-described embodiment, and various modifications and design changes can be made without departing from the spirit of the invention.
【００１４】[0014]
本考案は前記の構成としたので、以下のような特有の効果を奏する。 軸受けホルダーを亜鉛合金ダイカスト製の一体成型としたので、吸湿すること がなく吸湿による締付けトルクの低下が生じない。従ってホルダーの横ズレがな い。 固定部と締付けボルトのヘッド下面に凹凸面を形成し、該部分で取付け溝の溝 壁を狭持するので締付けトルクが高まる。 Since the present invention has the above-mentioned configuration, it has the following unique effects. Since the bearing holder is made of zinc alloy die-cast, it does not absorb moisture and the tightening torque does not decrease due to moisture absorption. Therefore, there is no horizontal displacement of the holder. An uneven surface is formed on the lower surface of the fixing portion and the head of the tightening bolt, and the groove wall of the mounting groove is sandwiched at this portion, so that the tightening torque is increased.
