Abstract
1288603 Worm and pinion machines B ZIMMERN 17 Dec 1969 61484/69 Heading F1F A worm and worm-wheel motor, pump or compressor has the worm and worm-wheel so shaped and dimensioned that the wheel may be fitted into the worm by combined rotation about, and translation along, an axis 22, Fig. 3 lying in the plane of intermesh. The Specification gives the mathematical condition for such an axis to exist. The crests of the worm threads all lie on a surface of revolution about the worm axis, and the surface may be cylindrical, Fig.3, conical, Fig.1 (not shown) or planar (not shown). To enable assembly to take place the worm-wheel teeth may have tapered ends, Fig.7 (not shown), the worm may be truncated at the low pressure end by a conical surface, Fig. 8 (not shown) or a single worm thread may be truncated at the low pressure end, Fig. 9 (not shown). More than one wheel may mesh with a single worm. When the working fluid is gaseous, sealing is effected by liquid injected into the working spaces adjacent the inlet ports.
