1,216,671. Shafts; universal joints. SILENTBLOC Ltd. 5 April, 1968 [7 April, 19671, No. 16104/67. Heading F2U. A vehicle propeller shaft or other torque transmitting shaft comprises a metal tube 1 connected at its ends to coaxial metal coupling parts 4A, 5A by sleeves 6 of resilient plastics material (e.g. polyurethane) bonded thereto. The plastics material is poured or injected between the tube 1 and parts 4A, 5A in an uncured state and bonds itself to the metallic surfaces during setting. During bonding one end of the space between the tube 1 and coupling part is sealed by thin metal, plastic or papier-mache seals 2, 3 which also locate the coupling part 4A or 5A concentrically within the tube 1. In Figs. 5 and 6 (not shown), the coupling parts (10, 10A) surround the tube (8) and detachable seals (9, 13) are used during bonding. In Fig. 7 (not shown), the tube (1) and coupling parts (4A, 5A) are connected by plastic sleeves to an intermediate metal sleeve (15). In Figs. 8 and 9 (not shown), the centre of the plastic sleeve (29) is not bonded to one or the metallic surfaces, a cardboard sleeve (25, 33) preventing such bonding in the central region. |
