Abstract
A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a tip seal(s), an eccentric drive mechanism which drives the orbiting plate scroll, and an axial compliance system. The eccentric drive mechanism includes a crankshaft, and bearings and a counterbalance disposed on the crankshaft. The counterbalance is mounted so as to be slidable along the crankshaft in the axial direction of the crankshaft. The axial compliance system includes a flexure and one set of springs for pre-loading the bearings. The flexure is interposed between one of the bearings and the counterbalance. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll.
