摘要:

This paper deals with bearings supported on metal beams under mechanical stress in the axial direction. Because of a phenomenon related to the bending of long columns under axial compression the torque of the total arrangement can be made zero or even negative. Such a bearing can be designed with two decisive advantages, absolutely no friction, and practically no restoring torque as far as small angles of rotation are concerned. Two different types of beam bearings are treated, and their equations for precalculation are derived. Furthermore, the influences of temperature, external forces, and the angle of rotation on the torque of the bearing are investigated. Finally, a combination of two different beam bearings is shown to offer a possible compensation for these unfavorable effects.
