になっている。Conventional ball joints used in the steering linkage of vehicles such as automobiles, for example, in the joints at both ends of a drag link, have a risk of rotating due to the movement and vibration of the drag link while the spherical bearing member is running. As shown in FIGS. 1 and 2, a conical notch is provided on the side surface of a cylindrical spherical bearing member 2 housed in a cylindrical housing 1 formed at the end of the drag link, and the spherical portion 2A is Vertical donut-shaped cavities 4A and 4B are formed on both sides of the supported spherical shaft 3 to prevent mutual interference with the spherical shaft 3 even when the spherical bearing member 2 rotates. It has a structure.
しかしながら、かかる従来の構造では、球面軸受部材の
球面部２Ａにおける球面軸３を支承する接触面積が減少
し、面圧が高くなり、球面軸受部材２と球面軸３とにお
ける摩耗が増大傾向になるという欠点があった。However, in such a conventional structure, the contact area for supporting the spherical shaft 3 in the spherical portion 2A of the spherical bearing member decreases, surface pressure increases, and wear between the spherical bearing member 2 and the spherical shaft 3 tends to increase. There was a drawback.
本考案は、この欠点を解消するためになされたものであ
り、その目的は、球面軸受部材が球面軸の回動や振動に
より回動されることを簡単な構造にて防止できる玉継手
における球面軸受部材の回止め構造を提供するにある。The present invention was made to eliminate this drawback, and the purpose is to prevent the spherical bearing member from rotating due to rotation of the spherical shaft or vibration with a simple structure. The present invention provides a rotation prevention structure for a bearing member.
本考案の特徴は、前記玉継手において、球面軸受部材を
、球面軸の球面中心と球面軸受部材の外形が構成する円
形の中心軸とが互に偏心するように設定し、球面軸の回
動や振動によって球面軸受部材がとも回りされないよう
にした点、にある。A feature of the present invention is that in the ball joint, the spherical bearing member is set so that the spherical center of the spherical shaft and the circular central axis constituted by the outer shape of the spherical bearing member are eccentric from each other, and the rotation of the spherical shaft is The reason is that the spherical bearing member is prevented from being rotated by vibrations.
以下図面に即して本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to the drawings.
第３図および第４図は、本考案を自動車等車両のステア
リングドラッグリンクの継手部に使用した場合の１実施
例を示しており、図においてドラッグリンクの端部１１
（端部のみ図示）には、円筒形状のハウジング１が形成
され、ハウジング１内には球面軸３が互に軸心が直交す
るように挿入されている。3 and 4 show an embodiment in which the present invention is applied to a joint part of a steering drag link of a vehicle such as an automobile.
A cylindrical housing 1 is formed (only the ends are shown), and spherical shafts 3 are inserted into the housing 1 so that their axes are perpendicular to each other.
そのハウジング１内には、ハウジング１の内径とほぼ等
しい外径を有する円柱形状の球面軸受部材１２が、球面
軸３を外側がら抱持するように収納されており、球面軸
受部材１２は、ハウジング１端部にねじ込まれ、がっ、
コツタピン６で回止めされたプラグ５に一端面を当接し
ており、また、球面軸受部材１２は、ハウジング１の底
部にスペーサ８を介して内装されたスプリング７に他端
面を当接してその弾発力により常時付勢されている。A cylindrical spherical bearing member 12 having an outer diameter approximately equal to the inner diameter of the housing 1 is housed in the housing 1 so as to hold the spherical shaft 3 from the outside. Screwed into one end,
One end surface of the spherical bearing member 12 is in contact with a plug 5 which is prevented from rotating by a screw pin 6, and the other end surface of the spherical bearing member 12 is in contact with a spring 7 which is installed in the bottom of the housing 1 via a spacer 8, so that the spring 7 is resilient. It is constantly energized by power.
よって、球面軸受部材１２は、スプリング７のばね荷重
により所定の位置に保持されて、球面軸３を支承してい
る。Therefore, the spherical bearing member 12 is held in a predetermined position by the spring load of the spring 7 and supports the spherical shaft 3.
ハウジング１外周上にはダストカバー９が被着されてお
り、このカバーの一部は球面軸３の外周に巻着し、ハウ
ジング１内にダストが侵入することを防止している。A dust cover 9 is attached to the outer periphery of the housing 1, and a part of this cover is wrapped around the outer periphery of the spherical shaft 3 to prevent dust from entering into the housing 1.
そして、前記球面軸受部材１２は、この部材における外
径の中心軸１２Ｂが球面軸３の球面３Ａの中心３Ｂに対
し偏心するように、球面部１２Ａの位置、形状その他を
適当に設定されている。In the spherical bearing member 12, the position, shape, etc. of the spherical portion 12A are appropriately set so that the central axis 12B of the outer diameter of this member is eccentric with respect to the center 3B of the spherical surface 3A of the spherical shaft 3. .
かくして、球面軸３はドラッグリンク端部１１の直角方
向においていずれの方向にも変位可能に支承されている
が、球面軸３がドラッグリンクの軸心と平行に回転し、
また、直角方向で回動し、または、若干振動しても、球
面軸受部材１２の外径中心軸１２Ｂが球面軸３の球面中
心３Ｂに対し偏心しているので、球面軸受部材１２は球
面軸３の動きに対しハウジング１に係合した状態となり
、ハウジング１内を回動変位することはない。Thus, although the spherical shaft 3 is supported so as to be displaceable in any direction perpendicular to the drag link end 11, the spherical shaft 3 rotates parallel to the axis of the drag link;
Furthermore, even if the spherical bearing member 12 rotates in the right angle direction or vibrates slightly, the outer diameter center axis 12B of the spherical bearing member 12 is eccentric with respect to the spherical center 3B of the spherical shaft 3. It is in a state of being engaged with the housing 1 with respect to the movement of the housing 1, and there is no rotational displacement within the housing 1.
よって、球面軸受部材１２は回止めされるので、球面軸
受部材１２には球面軸３との干渉を回避するために、球
面軸３の挿入側のみに空所部４を構成する切欠を形成す
ればよい。Therefore, since the spherical bearing member 12 is prevented from rotating, in order to avoid interference with the spherical shaft 3, a notch forming the cavity 4 should be formed only on the insertion side of the spherical shaft 3. Bye.
したがって、従来の場合に比べ、球面部について十分な
支承面積を確保することができ、よって、球面軸受部材
と球面軸とにおける摩耗が軽減化できる。Therefore, compared to the conventional case, a sufficient bearing area can be secured for the spherical portion, and therefore, wear on the spherical bearing member and the spherical shaft can be reduced.
以上説明する如く、本考案によれば、構造簡単にして、
球面軸受部材の回止めが実現できる。As explained above, according to the present invention, the structure is simplified,
It is possible to prevent rotation of the spherical bearing member.
よって、新たな部品や大きな設計変更を必要とすること
なく、コスト増が招来せず、また、保守点険も容易であ
る。Therefore, there is no need for new parts or major design changes, no increase in costs, and maintenance is easy.
さらに、球面軸との干渉を回避けるための空所部は、球
面軸受部材の球面軸の挿入側についてのみ形成すればよ
いので、十分な支承面積を確保でき、摩耗の軽減化を図
ることも可能である。Furthermore, since the hollow part to avoid interference with the spherical shaft only needs to be formed on the insertion side of the spherical shaft of the spherical bearing member, a sufficient bearing area can be secured and wear can be reduced. It is possible.
