<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing resistant to radial load, thrust load and angular load. <P>SOLUTION: Circular raceway surfaces 11, 21 are formed opposing each other on two bearing rings 10, 20. A ball 30 is mounted between the ball raceway surfaces 11, 21. The ball raceway surfaces 11, 21 have radial regions 11r, 21r including points 11p, 21p which a center line L1 intersects passing through a center C of the ball 30 in a radial direction R and thrust regions 11s, 21s including points 12p, 22p which a center line L2 intersects passing through a center C in a thrust direction S. The radial load from the radial direction R is received by the ball raceway surfaces 11, 21 in the radial regions 11r, 21r, the thrust load from the thrust direction S is received by the ball raceway surfaces 11, 21 in the thrust regions 11s, 21s, and the load from an angular direction is received by the ball raceway surfaces 11, 21 in the radial regions 11r, 21r and the thrust regions 11s, 21s. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
