  • the bottom shell and the frame are then brought up to the horizontal, whereupon the packing piece is inserted between the frame and the lugs on the housing and there secured, as, for instance, by connecting it to a part of the frame.
  • the frame may be provided with an attachment in the form of a lubricant reservoir, by means of which attachment it is supported in midposition relatively to the housing, preferably against longitudinal ribs thereon. In this case it is advantageous to lock the frame against axial displacement by attaching the aforesaid extension to the housing more particularly to a transverse rib on the same.
  • bottom shells whereof the middle part lies between the frame members locking against axial displacement is preferably effected by means of ribs provided in the housing, against which ribs the bowed arms of the frame bear on both sides, so as to lock the said frame and the bottom shell axially.
  • the bottom shell then preferably extends into the space between the ribs on the housing.
  • Figs. l and 2 are longitudinal and transverse sections through an axle bearing, showing one constructional embodiment of the same wherein the middle part of the bottom shell rests in a hollow on the frame. More particularly the left hand half of Fig. 2 is a section taken on line A-A of Fig. 1 and the right-hand half a section on line B-B thereof, while Fig. 1 is a longitudinal section on line C-C of Fig. 2.
  • Figs. 3 and 4 show an arrangement of the bottom shell wherein this latter is arranged wholly between the axle journal and the frame. More particularly, Fig. 3 is a vertical longitudinal section through the bearing on line D-D of Fig. 4, while Fig. 4, as regards its left-hand half is a vertical transverse section through the axle bearing, taken on line E-E of Fig. 3, while its right-hand half is a vertical section on line F-F of Fig. 3 with the bottom shell shown in end elevation.
  • the numeral l denotes the axle journal and 2 the end iiange or' shroud of said journal, which is mounted between a top shell 3 and a bottom shell 4.
  • this bottom shell which preferably has an insert 5 of bearing metal, is suspended in; a frame, which is connected directly to the housing 6.
  • This frame consists of two transverse arms 'I and 8 united, to form the frame, by means of two longitudinal bearers 9 and I0. Between the bottom shell 4 and the longitudinal bearers 9 and IIJ the devices for automatically adjusting the bottom shell consisting, in the embodiment shown in Figs.
  • the bottom shell 4 preferably has pan-shaped outriggers or side wings 2I which extend into the space 22 between the ribs I8 and I9 of the housing and serve to augment the lubricant catching effect which takes place especially in the vicinity of the edges 23 of the axle box.
  • the new method of fixing the bottom shell makes it extremely simple to disassemble and reassemble the whole bearing. For instance, if the packing piece I5 be removed, after drawing the split pin 29, the frame and the bottom shell can be shifted axially and this releases the connection between the frame arms 'I and 8 and the finger-like projections I4 of the housing. The frame and the bottom shell can thus be brought into an inclined position and drawn, past the axle journal shroud, out of the housing of the axle bearing. As may be supposed, assembly is carried out very simply, in the reverse order.
  • the numeral I again designates the axle journal and 2 the xed shroud of the same while 3 and 4 denote the top and bottom shells in which it is carried, the bottom shell preferably including a white metal lining 5.

  • the botl'tom shell itself is slotted at '34and in the slots are received ybars 24 which are pressed into engagement by means of the adjusting springs II and are provided with U-shaped positioning stirrups 25.
  • the locked screws 26, which fix the frame 'I-I to the lugs I5 on the housing, on which it rests, are rst released; then, by pulling down the stirrups 25, the springs II are sufciently compressed to permit the frame 'I-IIJ to be drawn out through the recesses 22 in the housing.
  • the bottom shell then falls of its own accord into the position in which it also can be withdrawn, past the shroud of the axle journal by a simple axial movement.
  • the bottom shell' 4 is first introduced by way of the frecesses 22 in the housing and then the frame A"1 -Ill. with the springs II compressed', is pushed When the springs II expand the bars 24, under their influence, enter the slot-like recesses 23 in the bottom shell 4 and in this way the said bottom shell positions itself automatically.
  • shocks set up as between the axle journal I and the housing 6 are imparted first to the bottom shell 4. Owing to the fact that this latter is arranged wholly between the axle journal I and the frame 'I-I and is separated from the frame solely by a predetermined and permissible shock absorbing path, the shocks, after a certain amount of damping while traversing the shock labsorbing path, are transferred to the fixed frame, through which they are carried directly to the housing' 6, or part I 6 thereof. In order that the shocks may be taken up in the actualdirection of impact, the frame 'I-Ill can, as shown in dot and dash lines in Fig.

  • fixing in the axial direction is effected, not through the agency of the flangelike extension 30 ofthe frame 'I-ID and the screw 26, but with fixing means 3
  • ribs'or ridges 32, 3'3 are preferably provided in the housing and the bottom shell 4, more particularly, the pan-shaped outriggers 2
  • the pan-shaped outriggers preferably, collect the lubricant which for this purpose or in order to lubricate the axle journal, is delivered from the top shell, according to its position, on top of the Between the bottom shell 4 and In this way the outriggers provide for primary or secondary lubrication of fthe axle 1 journal.
