Title The Design of Roller Linear Guide Accuracy and Friction Test Bed
Abstract
Based on the analysis of the current test technology and research of the roller linear guide accuracy and friction, a test bed for the measurement of the roller linear guide accuracy and friction was designed.
Through market research and analysis, the measurement principle of accuracy and friction were put forward. Combined with practical application, the characteristic parameter and functional requirements of the test bed were determined, as well as the overall design. And then after comparison and analyzing several programs of driving component, the best one was elected.
According to the design requirements of the bed, the structure of bed component, working mesa component and right angle drive component were designed respectively while the components which effect the accuracy and friction of the test bed were checked, which combine with the assembly methods to accomplish the structure designing of each component. On this basis, the entire structure of the test bed was assembled by all components.
Moreover, the measurement system was simply design, and part of the hardware was chosen.
