Abstract
Quenching heat treatment is performed on a whole rocker arm bearing assembly in which shaft ends of a supporting shaft are fixed to inner peripheral edges of shaft end insertion holes of a pair of opposite sidewalls, and by the outer ring is rotatably supported on a raceway portion of an shaft intermediate portion of the supporting shaft through a plurality of rolling elements or directly, thereby manufacturing a rocker arm bearing apparatus.
Claims20
A method of manufacturing a rocker arm bearing apparatus that includes a pair of opposite sidewalls including shaft end insertion holes, respectively;
- a supporting shaft that includes a raceway portion on an intermediate portion thereof and opposite shaft ends fixed to inner peripheral edges of the shaft end insertion holes, respectively;
- and an outer ring rotatably supported on the raceway portion through a plurality of rolling elements or directly, the method comprising:
- inserting the opposite shaft ends into the shaft end insertion holes, respectively;
- fixing the shaft ends to the inner peripheral edges of the shaft end insertion holes to form a rocker arm bearing assembly in which the shaft ends are fixed to the inner peripheral edges of the shaft end insertion holes and the outer ring is rotatably supported on the raceway portion through the plurality of rolling elements or directly;
- and
- performing quenching heat treatment on an entirety of the rocker arm bearing assembly.
A method of manufacturing a rocker arm bearing apparatus comprising:
- forming a pair of opposite sidewalls including shaft end insertion holes;
- providing a supporting shaft that includes a raceway portion on an intermediate portion of the supporting shaft and opposite shaft ends fixed to inner peripheral edges of the shaft end insertion holes;
- forming an outer ring rotatably supported on the raceway portion;
- inserting the opposite shaft ends into the shaft end insertion holes;
- fixing the shaft ends to the inner peripheral edges of the shaft end insertion holes to form a rocker arm bearing assembly in which the shaft ends are fixed to the inner peripheral edges of the shaft end insertion holes and the outer ring is rotatably supported on the raceway portion;
- and
- performing quenching heat treatment on an entirety of the rocker arm bearing assembly.
A rocker arm bearing apparatus comprising:
- a pair of opposite sidewalls including shaft end insertion holes;
