DE2638996A1 - Sliding radial bearing with separate thrust ring - has tabs engaging bore contg. radial bearing to prevent rotation of ring - Google Patents

Abstract

The sliding bearing assembly has a radial bearing (3, 4) and two separate thrust rings (8) arranged at the respective ends of the radial bearing. The thrust rings have radially inwardly projecting tabs (6) which are bent in the axial direction to engage slots in the radial bearing. The tabs and slots prevent rotation of the thrust rings. The tabs engage the housing bore (10) contg. the radial bearing to locate the rings radially. The radial bearing comprises two half-shells. Each ring also comprises two halves and these may be connected by interengaging elements at their adjacent ends.

Description

Split radial axial plain bearing

The invention relates to a split radial axial slide bearing with detachable Axial plain bearing segments with projections on the inner circumference in corresponding Engage recesses in the bearing shells.

Such plain bearings are known (DT-OS 2 433 928). You have opposite an integral axial-radial bearing has the advantage that for the radial bearing a different bearing material can be selected than for the axial bearing, so that a optimal material adaptation to the respective load conditions is possible. Furthermore, there is an improved load on the axial bearing by a frame the dimensions possible free axial contact possibility.

The centering and fixing of the bearing parts cause difficulties to each other. For this purpose, projections are provided on the axial plain bearing segments, which engage in corresponding projections of the bearing shell. This creates a fixation reached in the circumferential direction, while a centering takes place in that the axial sliding bearing segments support themselves on their inner circumference on the bearing shell. A fixation after outside, as a rule, on the outer circumference by means of indentations in the housing.

The invention is based on the object of using simple means Centering and fixing of the bearing parts in the circumferential direction and in the radial direction to reach. This object is achieved according to the invention in that the projections are formed by lugs that are bent in the direction of the bearing axis and are Support on the Lågersohrung.

The axial plain bearing segments are both in the circumferential direction through the lugs secured as well as in the radial direction through the bearing bore inwards and outwards centered without centering on the outer circumference of the axial plain bearing segments The radial axial plain bearings are therefore easily against normal Interchangeable radial bearings.

The task at hand can be achieved with a split radial axial plain bearing with detachable axial plain bearing segments that are located on the inner circumference of the bearing shell support and engage with projections in corresponding recesses in the bearing shells, can also be achieved in that the axial sliding bearing segments at their separation points Have notches. As a result, the axial plain bearing segments are both after fixed inside as well as outside.

The projections and recesses can advantageously according to an embodiment of the invention are designed and arranged so that the bearing parts are not interchangeable.

Exemplary embodiments of the invention are shown in the drawing.

In a bearing housing, which consists of a bearing housing upper part 1 and a Bearing housing lower part 2 consists of an upper and lower bearing half-shell 3 and 4 used. On the front sides of the housing 1, 2 sin + xialgleitlagersegmente 7 and 8, which engage in recesses 5 with noses 6. The noses 6 are bent in the direction of the bearing axis 9 and are supported on the bearing bore 10. The axial plain bearing segments 7 and 8 are thus both in the radial direction and secured and centered in the circumferential direction.

In the embodiment according to FIGS. 5 to 10, the bearing half-shell 11 such a width that the axial sliding bearing segments 12 with their inner Perimeter 13 can be supported on the outer circumference of the bearing half-shell 11. Among themselves the axial sliding bearing segments 11 and 14 are connected to one another by means of latches 15 tied together. Furthermore, the axial sliding bearing segments 12 and 14 are opposed by lugs 16 Twisting secured and centered in the radial direction.
