抄録

Even when the temperature of the ball screw reaches steady state, the change of its distribution is repeated as the nut goes and returns. In this study, the repeated change is numerically analysed by a difference method on several idealization, where the screw shaft is replaced by a solid cylinder and the nut is replaced by a hollow cylinder. This thermal phenomena is treated as a contact problem between two cylinders. The following results are obtained: (1) The temperature of the screw shaft is higher just around the nut. Therefore, it is expected that the forced cooling of the screw surface near the nut is effective. (2) There is almost no temperature gradient in the radial direction. Therefore, there is a possibility that the heat transfer of the ball screw can be regarded as one dimensional problem.
