Bearing malfunction detecting device

摘要

A bearing malfunction detecting device can detect abnormal abrasion of a bearing by which a shaft is rotatably held. The detecting device comprises an annular plate coaxially and securely disposed about the shaft to rotate therewith. A wire carrier is connected to a fixed support member at a position near the annular plate. The wire carrier has a recessed head portion which spacedly receives therein an peripheral portion of the annular plate. A detecting device is used for detecting breakage of the recessed head portion.
