ANORDNING FOR PROVNING AV AXELLAGER I EN HOGVAKUUMKAMMARE

摘要

An apparatus has a rotatable shaft driven within a vacuum chamber through a magnetic clutch. A mounting block is carried on a test bearing adjacent one end of the shaft and is restricted from rotating with the shaft by a friction torque measuring device engaged therewith. The block is subjected to axial and radial loads which are adjustably variable during testing by control devices located outside the vacuum chamber and connected to the mounting block by traction linkages passing through seals in the chamber walls. The test bearing is heated inductively; cooling discs and a reservoir are provided on and adjacent the shaft. Vibration measuring and visual observation devices are also disclosed.
