PLAIN BEARING BUSH FOR PLAIN BEARINGS WITH INCREASED LOAD-BEARING CAPACITY

摘要

The invention relates to a plain bearing bush (10) which comprises a cylindrical main body (11) with a first shell surface (12) and a second shell surface (14). The plain bearing bush (10) comprises a plurality of interchange bores (20) for a lubricant (30), wherein at least one of the interchange bores (20) has a first diameter (27) on the first shell surface (12) and a second diameter (29) on the second shell surface (14). The second diameter (29) is greater than the first diameter (27) in order to increase a load-bearing capacity (56) of the plain bearing bush (10). Two axially spaced-apart interchange bores (20) are connected to one another on the second shell surface (14) by way of a pocket depression (28). The invention also relates to a plain bearing (40) which is equipped with a plain bearing bush (10) of this type, and to a planetary transmission (50) which has a plain bearing (40) of this type. The invention likewise relates to a wind turbine (60) and to an industrial application (70) with a planetary transmission (50) of this type. Furthermore, the invention relates to a computer program product (80), by way of which an operating behaviour of a plain bearing bush (10) according to the invention can be simulated.
