Definitions

  • the forged steel bearing blocks with supporting arms forged thereon are made in two parts each having one arm, and being interconnected by suitable means, the joint of these two parts lying in a plane extending through the axis of the hub. Consequently, the bearing blocks consist of two parts with an arm on each. Rings shrunk on the ends of the hub have been found to be particularly suitable as means for interconnecting the two parts.
  • the production of these bearing blocks in two parts presents considerable advantages and facilities in the production both in making the rough forging and in finishing.
  • the parts each provided with only an arm can be shaped, deformed or forged in a simple manner whereas in the case of a one-piece bearing block the two arms hinder and render difficult the shaping.
  • the main advantage is,
  • Fig. 1 shows in elevation a section through the 20 joint I-I in Fig. 2.
  • Fig. 2 is an end view of Fig. 1.
  • Fig. 3 shows a modified form of construction in longitudinal section on line III-III of Fig. 4.
  • Fig. 4 is an end view of Fig. 3.
  • the pedestal or bear- 25 ing block I is composed of two parts 2 and 3 which are connected.
  • the latter is provided with ring-shaped or annular recesses 9 so that the bearing surface has interruptions or breaks.
  • the shrunk rings 4, 5 are slipped into recesses turned in the ends of the hub so that their peripheral surfaces merge into that of the hub. The shrunk rings are therefore scarcely visible 35 on the finished workpiece.
  • Fig. 2 shows that each part has a narrow tongue engaging in a corresponding groove in the other part.
  • Figs. 3 and 4 40 differs from that shown in Figs. 1 and 2 in that the shrunk rings 6, l are not placed in recesses like the rings 4 and 5, but project above the peripheral surface of the hub.
  • the arm I is integral with part 2 and the arm 45 8 is integral with part 3.
  • Bearing block to be used on marine vessels, of forged steel with arms forged thereon, characterized in that it is composed of two parts each provided with one arm, the joint of these parts being situated in a plane extending through the axis of the hub of the bearing block, the two parts being united by rings shrunk on the ends of the hubs.
