| Abstract: | The spatial RSSR mechanism with its input and output perpendicular to each other is a kind of most widely used spatial 4-link mechanism. This paper deduces its design formula involving only the dimension parameters, by taking the maximum pressure angle equal to the allowable pressure angle, and also discusses the problem about the limit value of pressure angle. The paper makes use of CAD and gives a numerical example for illustration. |
