Abstract
976,681. Balancing shafts. LANDISGENDRON S.A. April 17, 1963 [April 20, 1962], No. 15066/63. Heading F2U. [Also in Divisions B3 and F1] A shaft 4 of a turbine, compressor, grinding wheel &c. is dynamically re-balanced on imbalance, when two masses 14, 16 are automatically acted upon by fluid pressure to move circumferentially around a ring-shaped channel 6 in a drum 2 fast with the shaft, the channel also constaining a fixed mass 12 forming a partition and a diametrically opposite stop 18. A differential pressure generating device, comprising a ring-shaped chamber 44 through which passes the shaft 4, is fed with fluid under pressure, e.g. oil or air, through a pipe 46. The fluid under pressure in the chamber 44 passes through ports 38 &c. to shaft ducts 32 &c. and ports 26, 28, 30 located between the movable masses 14, 16. If imbalance occurs in apparatus mounted on the shaft 4, as by breaking of a blade of a turbine or compressor or by irregular wear of a grinding wheel, the shaft gyrates and its axis moves off-centre relatively to the differential pressure generator 44 &c. Those ports 38 &c. of the differential pressure generator nearest to the side of the ring-shaped chamber 44, e.g. as shown in Fig. 3 the ports 38, 42, are then subjected to an increased pressure. This increased pressure is fed through the shaft ducts 32, 36 and the ports 26, 30 to move the masses 14, 16 around the channel 6. When the shaft 4 &c. has been rebalanced, it stops gyrating and returns to its central position within the chamber 44. The masses 14, 16 are then maintained in their equlibrium position. As a modification, the fixed mass 12 may be replaced by a lightweight partition in association with a compensating mass fixed on the drum 2.
