<p>PCT No. PCT/DE94/00033 Sec. 371 Date Jul. 20, 1994 Sec. 102(e) Date Jul. 20, 1994 PCT Filed Jan. 18, 1994 PCT Pub. No. WO94/18455 PCT Pub. Date Aug. 18, 1994.A gear machine (pump or motor) has two externally meshing gear pairs (21, 22) which are arranged so as to be offset relative to one another and are attached to a drive shaft (31) by a toothing (30), the number of teeth of the toothing (30) being an even-number multiple of the external teeth of the driven toothed wheels (16, 18). The toothing width (b) of the driven toothed wheels (16, 18) on the drive shaft (31) is smaller than their toothed wheel width (B), in particular smaller than one-half the toothed wheel width (B). This improves the mechanical characteristics of the gear machine its operating reliability. The invention can also be used with gear machines with only one gear pair (21a).</p> |
