Grashof mechanism

WebF. Grashof classified four bar mechanisms into three types (double-cranks, rocker cranks, and double-rockers) and gave a set of rules for identifying the different types. WebJul 6, 2016 · The other remaining links follow the same naming convention as listed above. A slider crank fourbar cannot be classified as Grashof or non-Grashof. Sixbar. Sixbar linkages are mechanisms that are constructed from six liks and seven joints where each joint connects two links and two of the links have an additional joint along them.
