Abstract

The shell (10) has a guide element (30) for guiding lubricant, arranged at interior circumference and closing a bearing space between the slide bearing shell and a plain bearing. The guide element is arranged in a lubricant channel (20) that extends over inner circumference of the shell. The guide element includes two contact surfaces contacting with the plain bearing. The guide element is formed of soft, flexible material, and includes a reinforcing element e.g. band and/or strip-shaped element i.e. metal insert, and a sliding layer. An independent claim is also included for a method for manufacturing a slide bearing shell.

Description

The The invention relates to a plain bearing shell with at least one partially over the inner circumference extending lubricant channel according to the preamble of claim 1. The invention also refers to a particular use of such a bearing shell and to a method for producing plain bearing shells and on a bearing assembly.

Under A lubricant channel becomes an area in the plain bearing shell understood in which the lubricant, in particular lubricating oil, can flow. In particular, under a lubricant channel a lubricant groove understood.

such Plain bearing shells are well known and are mainly used in Internal combustion engines used to support the crankshaft. The Main bearings are made with channels of lubricant, lubricating oil supplied, the oil over an oil groove in the plain bearing cup over the main pin the connecting rod journal and thus the connecting rod is supplied. It was found that only a maximum of 25% of up to the connecting rod bearing arrives. This is due to the fact that the oil losses mainly in the axial direction relative to the main bearing shell, d. H. perpendicular to the groove direction, are very big.

The oil drain becomes with increasing play between the plain bearing shell and the Backlashes, such as waves or cones favors. To constantly ensure adequate lubrication are correspondingly large oil pumps for promotion a sufficiently large amount of oil required. A shortage and thus a demolition of the oil film in the Bearings and the insufficient supply of the connecting rod with oil would cause a quick wear or scuffing the sliding partner and lead to a show failure of the bearing.

The caused by the oil drain pressure reduction in the lubricant channel can also z. B. affect the camshaft position.

To remedy this, be in the DE 10 2004 028 773 A1 Expander proposed, which are arranged either between the bearing housing and the plain bearing shell or between plain bearing shell and shaft. It is according to the DE 10 2004 028 773 A1 have been recognized that Spaltentstehungsprozesse can be compensated by expansion elements. In particular, it has been recognized that it is possible to dispense with the use of heavy metals, which have to be optimized in a particularly complex manner with respect to their thermal expansion coefficient. There are proposed expansion elements, which may be made of lightweight materials to compensate for expansion processes of the components.

When Elongation elements are proposed such that a larger Have coefficients of thermal expansion as the materials, from which the bearing element and the shaft to be supported or the bearing shell are made.

So far arranged the expansion elements in the sliding surface of the bearing shell are, they are located on the bearing shell edge and thus spaced to the lubricant groove. This embodiment has the disadvantage that in the bearing shell additional grooves for insertion the Dehnstreifen are required, which is the preparation of the bearing shell expensive.

There the expansion elements have a high thermal expansion coefficient can, with a small gap between the bearing shell and Wave under circumstances at high temperatures through the expansion elements a clamping pressure to be built, the rotation of the shaft through the increase in the friction losses hindered, or the wear of the expansion elements increased, whereby they lose their effect.

aim engine development is to reduce fuel consumption. By a lower oil production can also smaller oil pumps, d. H. less powerful oil pumps, be used.

It is therefore an object of the invention to provide a plain bearing shell, the no or only slight lubricant losses during operation allows and which is simple and inexpensive to be finished.

These Task is solved with a plain bearing shell, which thereby is characterized in that the guide element consists of a soft, flexible material and at least one reinforcing element having.
