| Outline of Final Research Achievements |
In this study, first, the effects of radial loads and misalignment on the cage creep of conventional crossed roller guides were examined. Next, to reduce the failure risk of stud roller guides (which can prevent the cage creep), the contact forces and stresses of the studs and dimples were analyzed. Finally, for reducing the contact forces and stresses of the studs and dimples, it was shown that by using silicon nitride stud rollers and silicon nitride cylindrical rollers is effective.
