1,213,201. Securing on or in shafts. WESTWIND TURBINES Ltd. 30 Dec., 1968 [11 Jan., 1968], No. 1712/68. Heading F2U. A shaft 1 has a diametral bore 4 containing two identical elements 5a, 5b held together (e.g. by "0"-rings 7a, 7b) to allow limited relative longitudinal movement so that an end of each element 5a, 5b protrudes beyond the bore 4 to frictionally mount a member (e.g. an air-turbine wheel) on the shaft. The shaft 1 may have an axial bore 2 with mating bores 6a, 6b, to grip a member (e.g. a drill 3, tap or reamer) in the bore 2. |
