Abstract

The invention relates to an axially and radially loaded bearing comprising an assembly ring (4) which is mounted on the radial outer surface of the bearing and seals the bearing chamber. A bearing washer (1) is arranged in an annular housing (5) of the assembly ring (4) and is obstructed, in the axial direction, between a radial surface and a radially deformed edge (7). The other bearing washer (2) is surrounded by the assembly ring, leaving a gap. An annular protrusion (8) provided in the region of the radial outer surface (9) of one (1) of the bearing washers is driven into the assembly ring (4) when the edge (7) is deformed. .

Description

The invention relates to a bearing with axial and radial load.

  axial and radial load with an assembly ring which is mounted on the radial outer surface of the bearing and seals the bearing chamber, a bearing washer being arranged in an annular housing of the assembly ring and being fixed by obstacle, in the axial direction,

  between a radial surface and a radially deformed edge and the other round

  bearing delle being surrounded by the assembly ring leaving

remain a gap.

  Document US 22 41 032 discloses a ball bearing which is provided with an assembly ring intended to prevent separation

  elements and retain the lubricant in the bearing chamber during

  while walking. The assembly ring also provides protection against ingress of dirt, etc. coming from outside. The assembly ring, essentially L-shaped, surrounds one of the bearing rings and is mounted by a wing on the radial outer surface of the other bearing washer. In order to ensure precise mounting, an annular recess is provided with a radial bearing surface, into which the rolling washer is inserted. An obstacle fixing in the axial direction, on both sides, is obtained by deformation of the edge

free of the assembly ring.

  However, when the diameter of a ball bearing of this type is relatively large and the bearing operates at a high speed, the high centrifugal forces cause the lubricant to exit slowly through the gap between the assembly ring and the washer. bearing which are not sufficiently tightly connected with the adjustment and fixing. This is particularly the case for bearings used in dry clutches, whose operation is disturbed by the slightest

  amount of lubricant reaching between the friction surfaces.

  The object of the invention is to improve a bearing with axial and radial load of the type indicated in the introduction so as to prevent

  the lubricant outlet safely, even in the presence of central forces

high trifuges.

  This objective is achieved by means of an annular projection which is

  arranged in the region of the radial outer surface of one of the rounds

  bearing and which enters the assembly ring during the

deformation of the latter.

  Thanks to the tapered annular projection, it occurs when fixing

  tion a deformation of the material between the projection and the assembly ring.

  The projection on the rolling washer may for example be in the form of an edge and, by means of a suitable conformation of a cutting tool, may be produced during the machining of the radial outer surface.

  of the sheet metal bearing washer. After the hardening of the wheel washer

  Lement, the projection has a hardness greater than that of the assembly ring and, under the action of axial pressure during fixing, 20. sinks into the material of the bearing washer, or even deforms slightly to edge level. Taking into account the residual elasticity of the materials, an absolutely secure seal is obtained, even under

the influence of temperature.

  According to a preferred embodiment of the invention, the projection is

  is made in the form of an edge oriented in the axial direction.

  According to an alternative embodiment of the invention, the projection in

  edge shape extends axially outward.

  These characteristics as well as other characteristics will be described in the following with the aid of the example embodiments shown.

in the drawings.

  These show: Figure 1, the partial longitudinal section of a bearing with axial and radial load comprising an assembly ring and an annular projection oriented axially outward and Figure 2, the region of the fixing between the washer rolling and

  the assembly ring with an annular projection directed inwards.

  The axial and radial load bearing shown in Figure 1

  consists of two bearing rings 1, 2 made of sheet metal and balls 3 available

  between them. An assembly ring 4 is fixed to the bearing washer 1, which L-shaped assembly ring surrounds the other bearing washer 2 For mounting, an annular housing 5 with a radial bearing surface 6 is machined in the assembly ring 4. The edge 7 which is shown in its deformed form in the figure, originally extends under the

shape of a cylinder.

  The right-hand rolling washer i is provided with an annular projection 8 machined from the material, the outside diameter of which is connected without hooking to the radial outside surface 9 and forms a sharp edge. The projection 8 also has the hardness of the rolling washer 1 which has been subjected to a heat treatment. On the side axially opposite to the projection 8, the rolling washer 1 is provided with a centering recess 10.

  The bearing washer 1 being mounted in the assembly ring

  4 and being in abutment on the radial surface 6, the free edge 7 is deformed radially inwards. The annular projection 8 inclines slightly towards the interior and penetrates into the softer material of the assembly ring 4. A sealing ring-shaped sealing edge is thus closed with a sealing surface which continues on both sides of

  the edge. Due to the elastic return of the compressed material during deformation

  mation, the deformed edge 7 of the assembly ring 4, in the region of the projection, is prestressed and provides a perfectly tight seal

  durable preventing the passage of lubricant.

  In the embodiment shown in Figure 2, the projection

  annular is directed axially inwards so that, from the

  press the bearing washer 1 into the housing 5 of the assembly ring 4, the projection is inserted into the assembly ring,

  phenomenon which continues during the deformation of the edge 7.
