Abstract
A shaft structure for rotational support by a non-ball type bearing includes a spherical rotation-supporting section and a non-spherical section. The spherical rotation-supporting section provides a support for the shaft when the shaft rotates in an axial hole of the non-ball type bearing, thereby reducing the frictional area between the shaft and the inner periphery of the axial hole of the non-ball type bearing.
Claims9
A shaft structure for rotational support in a bearing having a cylindrical axial hole, the shaft structure comprising an outer periphery including a cylindrical rotation-supporting section and a non-cylindrical section, the rotation-supporting section having a cylindrical surface that extends over one-half a circumference of the outer periphery, and the rotation-supporting section providing support for the shaft when the shaft rotates in the axial hole of the bearing.
A shaft structure for rotational support in a bearing having a cylindrical axial hole, the shaft structure comprising an outer periphery including at least two cylindrical rotation-supporting sections, each two adjacent rotation-supporting sections having a non-cylindrical section therebetween, and the rotational-supporting sections providing support for the shaft when the shaft rotates in the axial hole of the bearing.
