Apparatus for detecting bearing-seizing conditions in a reciprocating machine
First Claim
1. Apparatus for detecting degradation of lubrication conditions of smooth bearings connecting a crank shaft to a connecting rod or connecting the crank shaft to a body of a reciprocating machine, lubrication being provided by oil circulation, the apparatus including means for detecting a phenomenon of seizure, wherein the apparatus comprises an additional bearing serving as a test bearing, said test bearing being lubricated by circulation of the same oil as is used for the other bearings and supporting a radially-loaded rotating shaft, said detection means being fitted to the test bearing which also includes means enabling said test bearing to be more sensitive than the other bearings to degraded lubrication conditions.
