Abstract
(EN)
Disclosed is a cam follower wherein the size and the cost thereof are reduced by using a high-strength stud having a fiber flow continuously formed over each part without disconnection of the fiber flow caused by cutting. The cam follower is comprised of an outer ring (43) having an outside track surface (43a) on the inner periphery; a stud (31) having an inside track surface (34a) opposite to the outside track surface (43a), wherein a jaw portion (33) adjacent to one side of the inside track surface (34a), and a side plate press-fit portion (36) and an attachment shaft portion (38), which are adjacent to the other side of the inside track surface (34a), are formed in this order, and a fiber flow is continuously formed along the surface from the jaw portion (33) to a bearing supporting portion (34) in which the inside track surface (34a) is formed on the outer periphery; rolling elements (44) arranged between the outside track surface (43a) and the inside track surface (34a); and an inside plate (53) which is press-fitted to the side plate press-fit portion (36), to restrict the axial movement of the outer ring (43) and the rolling elements (44) in cooperation with the jaw portion (33).

L'invention porte sur un galet suiveur dans lequel la dimension et le coût de celui-ci sont réduits par utilisation d'un goujon de résistance élevée ayant un flux de fibre en continu formé sur chaque partie sans libération de l'écoulement de fibre provoqué par la découpe. Le galet suiveur est composé d'une bague externe (43) ayant une surface de piste extérieure (43a) sur la périphérie interne ; d'un goujon (31) ayant une surface de piste intérieure (34a) à l'opposé de la surface de piste extérieure (43a), une partie de mâchoire (33) adjacente à un côté de la surface de piste intérieure (34a), et une partie d'adaptation par pression de plaque latérale (36) et une partie d'arbre de fixation (38), qui sont adjacentes à l'autre côté de la surface de piste intérieure (34a), étant formées dans cet ordre, et un flux de fibre étant formé en continu le long de la surface de la partie de mâchoire (33) à une partie de support de palier (34) dans laquelle la surface de piste intérieure (34a) est formée sur la périphérie externe ; d'éléments de roulement (44a) agencés entre la surface de piste extérieure (43a) et la surface de piste intérieure (34a) ; et d'une plaque intérieure (53) qui est adaptée par pression sur la partie d'adaptation par pression de plaque latérale (36), pour limiter le déplacement axial de la bague externe (43) et des éléments de roulement (44) en coopération avec la partie de mâchoire (33).

 切削加工によるファイバーフローの切断がなく、各部位に亘って連続するファイバーフローを有する強度の高いスタッドを使用することにより、カムフォロアのコンパクト化と低コスト化を実現することを課題とする。 内周に外側軌道面43aを有する外輪43と、前記外側軌道面43aに対向する内側軌道面34aを有し、前記内側軌道面34aの一方の側に隣接する鍔部33と前記内側軌道面34aの他方の側に順に隣接する側板圧入部36及び取付軸部38が形成され、前記鍔部33から外周に前記内側軌道面34aが形成された軸受支持部34にかけて表面に沿ってファイバーフローが連続して形成されているスタッド31と、前記外側軌道面43aと前記内側軌道面34aの間に配列された転動体44と、前記側板圧入部36に圧入され前記鍔部33と協働で前記外輪43と前記転動体44の軸方向の移動を制限する内側板53と、によってカムフォロアを構成する。
