Increasing the Load Capacity of Ball-and-Screw Transmissions by Improved Assembly

摘要

The load capacity of a ball-and-screw transmission is defined as the maximum axial load that the transmission can withstand without residual plastic deformation at the contact surfaces of the screw, nut, or ball. Obviously, other conditions being equal, the load capacity of a ball-and-screw transmission will increase with the total contact area S in all the contact groups. According to the familiar formula in [1].
