• 論文の詳細を見る

• The theory proposed in the previous report is verified experimentally. The proposed theory is based on the clearance shape model with respect to the drunkenness error of an internal thread, and the frictional property of a sliding leadscrew is described under the hydrodynamic condition by some dimensionless numbers derived from the infinitely short bearing theory. To verify the proposed theory, some experiments are performed on several specimens which have different nominal dimensions. The experimental results are arranged according to dimensionless numbers S and M and are compared with the theoretical results. The experimental results agree with the theoretical results in the range of the hydrodynamic condition ; thus, the appropriateness of the proposed theory is verified. The appropriate driving condition is considered based on the theory and experimental results, and the selection criterion for oil viscosity is shown.
