Description
本発明の上記目的は、下記の構成により達成される。
（１） 円周方向に二以上に分割された分割部を含む分割軌道輪の製造方法であって、
表面の硬さがＨＲＣ５９以上であり、焼入れ焼戻し処理が施されており、表面の旧オーステナイト結晶粒度が６番以上である軌道輪を、
内径側を支持治具で吊持し、該軌道輪の軸方向の一端側に発生する応力が軸方向の他端側に発生する応力より大きくなるように前記軌道輪に径方向から荷重を加えて分割することを特徴とする分割軌道輪の製造方法。
（２） 前記分割部の円周方向端面の算術平均粗さが３０μｍＲａ以上であり、且つ前記分割部の円周方向端面がディンプル状になるように分割することを特徴とする（１）記載の分割軌道輪の製造方法。
The above object of the present invention can be achieved by the following constitution.
(1) A method of manufacturing a split race ring including a split portion that is split into two or more in the circumferential direction,
Hardness of the front surface is at HRC59 or more, and quenching and tempering process is performed, the bearing ring prior austenite grain size Ru der sixth above the front surface,
Hanged inner diameter side supporting jig, the load applied from the radial direction in the bearing ring so stress generated on one end side in the axial direction of the bearing ring is greater than the stress generated on the other end side in the axial direction method of producing segmented bearing ring, wherein the benzalkonium be split Te.
(2) the arithmetic mean roughness of the circumferential end faces of the divided portion is at least 30MyumRa, and the circumferential end of the dividing unit, characterized in that the dividing so that the dimple-like (1) according A method of manufacturing a split race.
このように、本実施形態に係る分割軌道輪の製造方法によれば、一方のスリット１７ｂからのみ亀裂を進行させて内輪１１を円周方向に分割するので、製造コストを増加させることなく切断面の乱れを抑制し、良好な切断面を得ることができる。また、分割による軌道輪の変形を抑制して、軌道面の真円度を良好なものとすることができる。また、分割面の密着性を高めることにより、分割内輪の耐久性をさらに向上させることができる。 Thus, according to the manufacturing method of the divided raceway ring concerning this embodiment, since a crack is advanced only from one slit 17b and inner ring 11 is divided in the circumference direction, a cut surface without increasing manufacturing cost Can be prevented, and a good cut surface can be obtained. In addition, it is possible to suppress the deformation of the raceway due to the division and to improve the roundness of the raceway surface. Moreover, durability of a division | segmentation inner ring can further be improved by improving the adhesiveness of a division surface.
