<p>A lever arrangement comprises a bearing pin and a supply space arranged next to the bearing opening of at least one of the levers and which contains a high-viscosity lubricant. In the operation of the lever arrangement with alternating tilting direction, the lubricant arrives, due to its inertia, in the respectively unstressed part of the bearing gap between the levers. The arrangement is suited particularly for highly stressed parts in the mechanism of circuit breakers which must be designed for space saving due to the small space available. The service life of such lever arrangements is increased substantially by arranging the lubricant in the supply space. The supply space can be part of a sleeve braced on the bearing pin.</p> |
