Description
【発明の詳細な説明】 本発明は自転車用ハブの改良に関する。[Detailed description of the invention] The present invention relates to improvements in bicycle hubs.
第２図は従来のハブ構造の一例を示しており、外輪部１
はハブ胴２に圧入固定され、ノ・ブ軸３にねじ止めされ
た玉押し４との間に転走体例えばボール５を介在させて
いる。Figure 2 shows an example of a conventional hub structure.
is press-fitted into the hub body 2, and a rolling element such as a ball 5 is interposed between it and a cone 4 screwed to the knob shaft 3.
第３図はハブ胴両端のフランヂ部１′を熱処理して外輪
部として使用する方式の例を示している。FIG. 3 shows an example of a method in which the flange portions 1' at both ends of the hub body are heat treated and used as outer ring portions.
上記何れの構戒のハブにおいても、車輪の円滑なる回動
を得るためには外輪部におげる転走軌道面の平行度或は
左右外輪部の軸心線の一致等の製作上の精度がきびしく
要求される。In any of the above-mentioned hubs, in order to obtain smooth rotation of the wheel, manufacturing considerations such as the parallelism of the rolling raceway on the outer ring or the alignment of the axes of the left and right outer rings are important. Accuracy is strictly required.
又これら従来の構造では衝突或は転倒等の衝撃による心
違い等により、車輪の回動が円滑にならなくなる欠点が
ある。Furthermore, these conventional structures have the disadvantage that the wheels do not rotate smoothly due to misalignment due to impacts such as collisions or falls.
本発明は上記従来の欠点を除去するもので、以下その一
実施例を説明する。The present invention eliminates the above-mentioned conventional drawbacks, and one embodiment thereof will be described below.
第１図において、第２図、第３図と同一符号は同一部分
を示し、説明を略す。In FIG. 1, the same reference numerals as in FIGS. 2 and 3 indicate the same parts, and the explanation will be omitted.
７は車輪の回転時に転送体５が転送する軌道面６を有す
る外輪部、１０は前記外輪部７の外周面８をその内面９
に密接させてこの外輪部７を保持し得るハブ胴である。Reference numeral 7 denotes an outer ring portion having a raceway surface 6 to which the transfer body 5 transfers when the wheel rotates, and 10 refers to an outer peripheral surface 8 of the outer ring portion 7 and an inner surface 9 thereof.
This is a hub body that can hold this outer ring portion 7 in close contact with the hub body.
前記外輪部７の外周面８と前記ハブ胴１０の内面９は、
ハブ軸中心線と転送体５の中心平面とが垂直に交差する
一点ｐを中心とする同一半径Ｒの球面に形成されている
。The outer circumferential surface 8 of the outer ring portion 7 and the inner surface 9 of the hub body 10 are
It is formed into a spherical surface having the same radius R and centered at a point p where the center line of the hub shaft and the center plane of the transfer body 5 perpendicularly intersect.
上記構或であると、外輪部７はハブ胴１０により保持さ
れしかも自由に揺動することができ、これにより衝撃に
よる歪み、或は製作誤差による心違いがあっても左右の
両外輪部７，７は自動調心され、ハブ胴１０の回動を円
滑ならしめることができる。With the above structure, the outer ring portion 7 is held by the hub body 10 and can swing freely, so that even if there is distortion due to impact or misalignment due to manufacturing error, both the left and right outer ring portions 7 , 7 are self-aligning and can smooth the rotation of the hub body 10.
以上のように本発明によれば製作が容易で心違いの発生
防止によって車輪を円滑に回転せしめる自転車用ハブを
提供できる。As described above, according to the present invention, it is possible to provide a bicycle hub that is easy to manufacture and allows wheels to rotate smoothly by preventing misalignment.
