Description

前記の目的を達成するために、本発明に係るローラバニッシュ加工装置は、クランクシャフトの軸部の外周面をバニッシュ加工するローラバニッシュ加工装置において、前記クランクシャフトの軸線方向に沿って延在して前記クランクシャフトの軸部の外径よりも小さい外径を有する一対のバニッシュローラと、一対の前記バニッシュローラを回転可能に支持する支持手段と、各前記バニッシュローラを前記クランクシャフトの軸部に向けて押圧する押圧機構と、を備え、前記押圧機構は、各前記バニッシュローラの外周面に線接触して回転する第１バックアップローラを有し、一対の前記バニッシュローラは、前記クランクシャフトの軸部の周方向に沿って並設された状態で当該クランクシャフトの軸部の外周面に線接触することを特徴とする。
In order to achieve the above object, a roller burnishing apparatus according to the present invention is a roller burnishing apparatus that burns the outer peripheral surface of a shaft portion of a crankshaft, and extends along the axial direction of the crankshaft. A pair of burnish rollers having an outer diameter smaller than the outer diameter of the shaft portion of the crankshaft, support means for rotatably supporting the pair of burnish rollers, and each vanish roller facing the shaft portion of the crankshaft And a pressing mechanism that presses, and the pressing mechanism has a first backup roller that rotates in line contact with the outer peripheral surface of each of the burnish rollers, and the pair of burnish rollers are shaft portions of the crankshaft. and wherein the line contact with the outer peripheral surface of the shaft portion of the crankshaft in a state of being arranged along the circumferential direction That.

上記のローラバニッシュ加工装置において、前記押圧機構は、前記第１バックアップローラの外周面に線接触して回転する第２バックアップローラ、を有していてもよい。
In the roller burnishing apparatus, the pressing mechanism may include a second backup roller that rotates in line contact with the outer peripheral surface of the first backup roller.

上記のローラバニッシュ加工装置において、前記支持手段は、一対の前記バニッシュローラを挟むようにして配設されて当該バニッシュローラの外周面に線接触して回転する一対のガイドローラと、各前記ガイドローラを軸支するリテーナと、を有していてもよい。
Axis in the roller burnishing processing apparatus, wherein the supporting means includes a pair of guide rollers which rotate in line contact with the outer peripheral surface of the burnishing roller is disposed so as to sandwich the pair of the burnishing roller, each said guide rollers And a supporting retainer.
