Abstract

800,839. Turbine rotor blade mounting. GENERAL ELECTRIC CO. Oct. 12, 1956 [Oct. 12, 1955], No. 31197/56. Class 110 (3). A bladed turbine rotor comprises a disc 12 having a rim extending laterally on both sides thereof, the rim being formed with spaces in which the platforms 19 of blades 13 are accommodated. The disc is formed inwardly of the spaces with apertures 16, 17 and sleeves or bushes 23 are secured therein, each sleeve projecting from both faces of the rotor disc. The blade platform 19 is formed on its lower surface with a pair of flanges 21, 22 which upon assembly are disposed across the ends of the sleeve 23, a pin 26 being passed through bores 24, 25 in the flanges 21, 22 and through the passage in the sleeve. The diameter of the pin 26 is substantially less than that of the passage in the sleeve 23 so that the pin is in line contact with the internal surface of the sleeve. The ends of the pin 26 are secured in the bores 24, 25 in the flanges 21, 22. When the blade is moved relative to the rotor disc, the pin 26 rolls on the internal surface of the sleeve.
