ROLLER BEARING WITH CIRCULATING ROLLERS AND BEARING LOAD MEASUREMENT FEATURE

摘要

A roller shoe comprising a body 2 having a guide track for the rollers is provided with at least one deformation sensor/transducer 3 mounted on the body 2 for measuring the load. The sensor/transducer 3 may be a strain gauge, a piezo-electric, a semi-conductive strip or a magnetostrictive element which is preferably mounted on a portion of the body not directly loaded, ie in the track 6 on the top surface of body 2 or in a bore in the body. Continuous load monitoring is thus provided. IMAGE
