• Effect of Herringbone Type Micro Patterning on the Large Roller End Face of Tapered Roller Bearing to Torque

抄録

Tapered roller bearing is used for various industrial machines because of high rigidity. However, the tapered roller bearing has a weakness that the running torque is larger than that of a ball bearing. The reason for the bearing have sliding contact area between the large roller end face and large inner flange face. Therefore, the authors attempted to reduce the running torque by attaching a herringbone type periodic micro groove on the large roller end face of the tapered roller bearing. In this paper, the authors changed position and direction of herringbone type micro groove and examined the effect to running torque. Because of the torque test, when the groove was applied to a position overlapping with the run mark portion, the running torque considerably increased. Conversely, it was possible to reduction the running torque most that sliding direction is reverse direction to the sliding direction of normal herringbone and the position where the groove does not overlap the running trace area, the P. C. D. of the groove is 7.9 mm, it was confirmed that we can reduce about 60% of the current product.
