Title: Bearing unit for wheel
Inventor: MACHINO TAKAMI
IPC: F16C19/18
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To keep plastic deformation inapt to Lee generated in an intermediate part even if excessive moment load is applied to an outer race by providing hardened layers from a double row inward raceway track part to the whole width of the intermediate part located between neighboring inward raceway tracks. SOLUTION: Double row inward raceway tracks 10, 10 are formed because an outer race 5 in which a mounting flange 11 is formed on the outer peripheral surface is formed integrally with carbon steel by forging and the outer peripheral parts of a plurality of rolling elements 3, 3 are abutted on the inner surface. On the surface of each of these inward raceway tracks 10, 10, hardened layers 12 are formed over the whole width including a fitting part 16 of a seal member 13 by induction hardening. Of the hardened layers 12 formed which are continuous to these inward raceway tracks 10, 10 and the intermediate part 15, the outside diameter of the hardened layer 12 of the intermediate part 15 is formed smaller than the outside diameters of the hardened layers 12 on the surface of each inward raceway track 10, 10.  Thus, toughness of the outer race 5 can be secured by suppressing thickness of the hardened layers 12.
