Abstract: A stator blade unit (1, Fig 1) for a turbomolecular pump comprises an array of polymer stator blades 2. The blade unit (1, Fig 1) may be formed in two semi-circular halves which link together to form a whole disk (Fig 2). The unit (1, Fig 1) may have an inner 6 and/or outer 7 rim which may be adapted to couple to adjacent stator blade units. The rims 6, 7 may also be formed as spacers so as to allow a rotor to fit between two adjacent units and the adjacent units linkable (25/26, Fig 5a/b). The blades 2 may be made from injection molding or additive manufacture (ie. 3D printing) and may be formed to have a softer polymer coating or layer on the blades 2. Further, the inlet side of the unit may be smoother than the outlet side of the blade to improve efficiency. The invention serves to be easy to manufacture, allows for more complex geometries, easy to produce to narrower tolerances and cheaper than the prior art. Also claimed are a method of manufacturing a stator blade unit suitable for use in a turbomolecular pump by injection moulding and a stator blade unit suitable for use in a turbomolecular pimp, with a unitary structure made by fluid moulding or additive manufacturing, having an array of blades and an outer rim.

Abstract: A quasi-zero stiffness composite beam structure for controlling low-frequency vibration of a longitudinal axial flow threshing drum. The structure comprises a left column (2), a right column (3), a quasi-zero stiffness composite beam (5), a composite beam right connecting member (8), and a composite beam left connecting member (9). A right side of the quasi-zero stiffness composite beam (5) is connected to the composite beam right connecting member (8). A left side of the composite beam (5) is connected to the composite beam left connecting member (9). The composite beam right connecting member (8) is connected to the right column (3). The composite beam left connecting member (9) is connected to the left column (2). The composite beam right connecting member (8) and the composite beam left connecting member (9) are connected, at a quasi-zero stiffness composite beam bearing position, to a threshing drum shaft (603) via a threshing drum bearing seat (602). When the combined total stiffness of the positive stiffness of a positive stiffness cross beam bearing a dynamic load of a longitudinal axial flow threshing drum and located in a balance position and the negative stiffness generated by prestress at an end of a negative stiffness bending beam shaft is approximately zero, a quasi-zero stiffness composite beam balance point is formed. The positive and negative stiffness beam structures are fixed, in a position where the quasi-zero stiffness composite beam is balanced, by a connecting screw. A gap between balance positions of the positive stiffness beam and the negative stiffness bending beam is filled with a connection pad. The invention can effectively control low-frequency vibration caused during longitudinal axial flow threshing.
