【考案の詳細な説明】 本考案は円筒状軸受の一部に鍔が設置された鍔付軸受に
関する。[Detailed Description of the Invention] The present invention relates to a flange bearing in which a flange is installed on a part of a cylindrical bearing.

鍔付軸受は円筒状の軸受部で軸の横力の力を支え、そし
てワッシャー状の鍔部で軸の縦刃の力を支えて回転を円
滑に行わしめるようになっている。A flanged bearing has a cylindrical bearing part that supports the lateral force of the shaft, and a washer-shaped flange part that supports the force of the vertical blades of the shaft to ensure smooth rotation.

従って、鍔付軸受は、鍔が軸のスラスト部と均一に接触
するような状態になっていないと軸のスラスト部や鍔を
損傷させてしまうことになる。Therefore, in a flanged bearing, unless the flanges are in a state in which the flanges are in uniform contact with the thrust portion of the shaft, the thrust portion of the shaft and the flanges will be damaged.

それ故、鍔付軸受はハウジングに嵌合された後、必ず鍔
と軸のスラスト部とは均一に接触するような状態、即ち
、鍔と軸受とは直角となっていなければならないもので
ある。Therefore, after a flange bearing is fitted into a housing, the flange and the thrust portion of the shaft must be in uniform contact, that is, the flange and the bearing must be at right angles.

従来より鍔付軸受は軸受部と鍔部の直角度に留意して軸
受と鍔の接合時、該直角度を正確に出すよう努力が払わ
れてきた。Conventionally, for flanged bearings, efforts have been made to pay attention to the perpendicularity between the bearing portion and the flange, and to accurately achieve the perpendicularity when joining the bearing and the flange.

しかるに、直角度が正確な鍔付軸受でもハウジングに嵌
合後、鍔付軸受に軸を挿入して回転させてみると鍔付軸
受の鍔部や軸のスラスト部が損傷していることがあった
。However, even if a flanged bearing has an accurate perpendicularity, when the shaft is inserted into the flanged bearing and rotated after it is fitted into the housing, the flanged bearing's flange or the thrust part of the shaft may be damaged. Ta.

斯様な鍔付軸受おび軸を詳細に観察してみると第１図に
示すように鍔付軸受の鍔２の外周部が軸Ｓのスラスト部
Ｔ方向へ傾斜していて鍔の外周部が軸のスラスト部に骨
接触するため損傷してしまうものであることがわかった
。When such a flanged bearing and shaft are observed in detail, as shown in Fig. 1, the outer circumferential portion of the flanged bearing 2 is inclined toward the thrust portion T of the shaft S. It was discovered that the thrust part of the shaft came into contact with bone, causing damage.

斯様に鍔が軸のスラスト方向に傾斜する理由は、軸受の
外径よりも細い径のハウジングにプレスや油圧装置で強
力に圧入するためである。The reason why the flange is inclined in the thrust direction of the shaft is because it is forcefully press-fitted into the housing, which has a diameter smaller than the outer diameter of the bearing, using a press or a hydraulic device.

つまり、ハウジングにそれよりも太い径の軸受を圧入し
ていくと軸受が内方へ絞られるようになるため、この絞
りに伴って軸受の一端に設置されている鍔も中心部が狭
められ、更に鍔の外周部が中心方向に引張られて鍔が軸
受本体とは逆の方向に傾斜してしまうからである。In other words, as a bearing with a larger diameter is press-fitted into the housing, the bearing will be squeezed inward, and as a result, the flange installed at one end of the bearing will also be narrowed in the center. Furthermore, the outer circumference of the collar is pulled toward the center, causing the collar to tilt in the opposite direction to the bearing body.

本考案者は上記従来の鍔付軸受の欠点に鑑み考案したも
ので、鍔付軸受をハウジングに圧入嵌合しても決して鍔
が軸受本体とは逆方向に傾斜することなく、しかも鍔の
設置角度に大きな許容範囲を持たせることができるため
、製造も容易に行えるという鍔付軸受を提供することに
ある。The inventor of the present invention devised the above-mentioned drawbacks of conventional flanged bearings, and even if the flanged bearing is press-fitted into the housing, the flanges will never tilt in the opposite direction to the bearing body. It is an object of the present invention to provide a flanged bearing that can be easily manufactured because it can have a large angle tolerance.

本考案の特徴とするところは、鍔が軸受の軸方向直角位
置から軸受本体方向へ０．３〜１０度傾斜している鍔付
軸受である。The feature of the present invention is a flanged bearing in which the flanges are inclined by 0.3 to 10 degrees toward the bearing body from a position perpendicular to the axial direction of the bearing.

以下図面に基づいて本考案を説明する。The present invention will be explained below based on the drawings.

鍔付軸受は円筒状の軸受１の一端にワッシャー状の鍔２
が摩擦溶接、ビーム溶接、アーク溶接、ロウ付等の接合
手段で接合されており、該鍔２は軸受の直角位置から軸
受本体方向、即ち軸のスラスト部とは逆の方向へ成る角
度αだけ傾斜している。A flange bearing has a washer-like flange 2 at one end of a cylindrical bearing 1.
are joined by a joining method such as friction welding, beam welding, arc welding, brazing, etc., and the flange 2 forms an angle α from the perpendicular position of the bearing toward the bearing body, that is, the direction opposite to the thrust part of the shaft. It is sloping.

該角度αは０．３〜１０度、好ましくは０．７〜７度で
ある。The angle α is between 0.3 and 10 degrees, preferably between 0.7 and 7 degrees.

本考案において鍔の傾斜角度を０．３〜１０度と限定し
たのは、傾斜角度が０．３度未満であると圧入嵌合時、
軸受の絞りによる鍔のスラスト方向への傾斜を十分補う
ことができず鍔がスラスト方向へ傾斜してしまうからで
あり、また１０度を越えると鍔付軸受を圧入嵌合して鍔
を直角に矯正した場合、鍔と軸受の接合部が平滑面とな
らず突出したり、或いは矯正時の変形量が大きいために
接合部に割れを生ずる虞れがあるからである。The reason why the inclination angle of the collar is limited to 0.3 to 10 degrees in this invention is that if the inclination angle is less than 0.3 degrees, when press-fitting,
This is because the inclination of the flange in the thrust direction due to the bearing throttle cannot be sufficiently compensated for, causing the flange to tilt in the thrust direction.Also, if the angle exceeds 10 degrees, the flange-equipped bearing must be press-fitted to make the flange at right angles. This is because, when straightened, there is a risk that the joint between the collar and the bearing will not be a smooth surface and will protrude, or that the joint will crack due to the large amount of deformation during straightening.

次に本考案鍔付軸受をハウジングに圧入嵌合する状態を
説明する。Next, the state in which the flanged bearing of the present invention is press-fitted into the housing will be explained.

第３図に示すように鍔付軸受をハウジングＨに図示しな
いプレスや油圧装置等で圧入してゆくと鍔２の外周がハ
ウジング面Ｆにあたるようになる。As shown in FIG. 3, when the flanged bearing is press-fitted into the housing H using a press or hydraulic device (not shown), the outer periphery of the flanged 2 comes to come into contact with the housing surface F.

ここで更に圧入を行うと鍔がハウジング面に押されて第
４図のようにハウジング面に密着して鍔のスラスト面が
平滑となる。If press-fitting is further performed here, the flange is pressed against the housing surface and comes into close contact with the housing surface as shown in FIG. 4, so that the thrust surface of the flange becomes smooth.

この時、ハウジングＨはハウジング面Ｆに対して直角に
穿設されているため鍔とハウジングは直角となり、それ
故鍔は軸受とも直角となるものである。At this time, since the housing H is perforated at right angles to the housing surface F, the flange and the housing are at right angles, and therefore the flange is also at right angles to the bearing.

鍔付軸受はハウジングに圧入嵌合後、鍔のバッククテン
ションで元の傾斜角度に戻ろうとするが、圧入による軸
受部の保持力が相当強いため該バックテンション程度の
力では容易に軸受がハウジングら抜は出るような心配は
全くないものである。After a flange-fitted bearing is press-fitted into a housing, it tries to return to its original inclination angle due to the back tension of the flange, but since the holding force of the bearing part due to press-fitting is quite strong, the bearing easily snaps into the housing with the force of this back tension. There is no need to worry about being left out.

本考案鍔付軸受は鍔の接合を軸受本体方向へ０．３〜１
０度という許容範囲内で行えるため、従来のように直角
度に留意する必要がなく製造も容易となる効果も有して
いる。In the flanged bearing of this invention, the joint of the flanges is 0.3~1 in the direction of the bearing body.
Since this can be done within the allowable range of 0 degrees, there is no need to pay attention to the perpendicularity as in the conventional case, which also has the effect of making manufacturing easier.
