Abstract

1452503 Shaft couplings DANFOSS AS 25 Nov 1974 [13 Nov 1973] 52703/73 Heading F2U A key 6, for coupling a gear 7 of an internally-meshing gear pump to a shaft 2, is made of a material comprising polyphenylene sulphide. The material may also contain up to 40% of reinforcing glass fibres, and is said to reduce fretting corrosion. The key 6 engages in a slot 5 (or alternatively in an aperture) at the end of shaft 2 and engages in slots 16 in gear 7. The key 6 permits radial movement of gear 7 relative to shaft 2 to compensate for misalignments.
