  • a suitable low friction bearing material may be provided on the inner concave tread 14 for rotating a shaft or the like.
  • a pair of thrust washers 24 are disposed on the main bearing 12 adjacent the opposite sides 20, 22.
  • the thrust washers 24 are curved in shape and have inner mounting surfaces 26 that face each other in the lateral direction, opposite, outward thrust washer surfaces 28 that face away from one another, a radial inner concave surface 30, a radial outer convex surface 32, and ends 34, 36 spaced on a circle.
  • the main bearing 12 is formed on its opposite sides 20, 22 with at least one and preferably a pair of recesses 38, 40.
  • the recesses 38 extend into the main bearing 12 from the opposite sides 20, 22, preferably through the entire thickness of the main bearing 12.
  • the thrust washers 24 are each formed with tongues 42, 44 projecting radially inwards, which are aligned with the recesses 38, 40 and be included accordingly.
  • the tongues 42, 44 lie opposite the three walls of the recesses 38, 40 and they secure the thrust washers 24 against rotation with respect to the main bearing 12 and they also support the thrust washers 24 against axial movement inwards on the rear wall of the recesses 38, 40.
  • the thrust washers are formed on their radially inward surface 30 with at least one support tongue or a partial tongue 48 which extends radially inward over a distance which is substantially less than that of the tongues 42, 44th and is supported on the outer surface 15 of the main bearing 12 at an interface 50.
  • the support tab 48 defines a radial gap 52 between the inward surface 30 of the thrust washers 24 and the outer surface 15 of the main bearing 12 away from the direct contact between the support tab 48 and the outer surface 15. Die Support tab 48 thus radially limits inward movement of thrust washers 24 with respect to main bearing 12, with tabs 42, 44 restricting the relative rotation and inward axial movement of thrust washers 24.
  • a fragile connection 54 connects the thrust washers 24 releasably against axial separation to the outside from the main bearing 12.
  • the connection 54 is formed at the interface 50 between the support tongue 48 of the thrust washers 24 and the outer surface 15 of the bearing 12.
  • the fragile connection 54 is one that is strong enough to hold the thrust washers 24 connected to the main bearing 12 during shipping and installation, but which breaks due to the application of an external axial force on the thrust washers 24 to the Release thrust washers 24 for the axial displacement outwards relative to the main bearing 12.
  • the frangible connection 54 may include an adhesive connection, a tack weld, or other breakable connection that attaches the thrust washers 24 during shipping and assembly Holds in place, but allows the thrust washers to separate axially outward due to the axially outward force.
  • the forces normally exerted on thrust bearings in an engine of a crankshaft application are sufficient to break the thrust washers 24 free from the main bearing 12.
  • the connecting force of the thrust washers is below the threshold of the pressure force that is normally encountered in the application.
  • the flange bearing 10 is installed, for example, in a crankshaft application, the main bearing 12 sitting in an engine block opposite to another flange bearing, as illustrated in FIG. 4, or in relation to a bearing shell, as is alternatively illustrated in FIG. 5 , wherein the outer thrust washer surfaces 28 are opposite a corresponding thrust washer surface of a rotating cam.
  • any pressure forces applied to the thrust washers by the action of the crankshaft which moves in any axial direction with sufficient force to break the fragile connection, become one or both thrust washers 24 or groups of thrust washers 24 in the event of a double 5 cause the thrust washer 24 to move axially outward from the main bearing 12 while its tongues 42, 44 are still trapped in the recesses 38, 40 of the main bearing 12 to preclude relative rotation of thrust washers 24 with respect to main bearing 12.
  • the thrust washers 24 on the link 54 are broken free and are able to move axially outward from their initial connection point on the link, but none the less become circumferential due to the continued reception of the thrust washer tongues 42, 44 within the Boundaries of the main bearing recesses 38, 40 held to exclude the movement in the direction of rotation.
  • the support tab 48 also maintains contact with the outer surface 15 of the main bearing 12 after the link 54 breaks and the thrust washer axially outwardly displaces, thereby maintaining the relative radial alignment of the thrust washers 24 and the main bearing 12, including the radial gap 52 therebetween ,
  • the ability of the thrust washer 24 to be broken free of the main bearing 12 to which it is initially connected has the advantage of relieving the entire bearing assembly of any stresses otherwise communicated to the bearing due to the bending forces that occur at the transition between the thrust washers and the Main camps are exercised.
  • the fragile connection is the only connection that secures the thrust washers 24 against external axial separation from the main bearing 12.
  • the outward limitation of the movement of the thrust washers 24 after separation from the main bearing 12 is controlled by supporting the bearing assembly when used in the engine or the like, with the thrust washer 24 supported on its rear 26 by a seat of the engine block and axially Outward movement is limited by the confrontation with the rotating thrust washer surface of the crankshaft.
  • the retaining tongues and the corresponding slots are preferably of a simple rectangular shape with no locking except in the The circumferential direction and they are preferably of different sizes, so that the thrust washers can only be installed with their thrust washer surfaces facing outwards and not inwards. This is to prevent the bearings from being inadvertently assembled, with the thrust washers facing in the wrong direction.

Abstract

L'invention concerne un ensemble rondelles de butée (10) comprenant un palier principal (12) cintré et des évidements (38, 40) s'étendant vers l'intérieur à partir de côtés opposés. Cet ensemble comporte au moins une rondelle de butée (24), laquelle est séparée du palier principal (12) et appuie sur une face externe radiale (15) du palier principal (12), ainsi que des languettes de retenue (42, 44) logées dans les évidements (38, 40) du palier principal (12) pour éliminer tout mouvement rotatif intermédiaire relatif. Cette rondelle de butée (24) est reliée au palier principal (12) par un raccord (54) fragile, de sorte que l'exercice d'une force suffisamment importante sur la rondelle de butée (24) dans l'axe vers l'extérieur provoque la rupture du raccord (54) maintenant la rondelle de butée (24), laquelle (24) peut ainsi être déplacée axialement vers l'extérieur du palier principal (12).
