ABSTRACT:
A device is disclosed for indicating the lubricating quality of a lubricating oil for a machine. The device comprises a frame and a rotatable shaft having a journal for rotation with the shaft. A housing having an internal cavity is mounted to receive the rotatable shaft with the journal disposed within the internal cavity of the housing. A journal-engaging member is mounted in the internal cavity for engaging the journal to establish a normal force between the journal-engaging member and the journal. An oil outlet and an oil inlet communicates with the internal cavity in the housing. The oil inlet and oil outlet are connected to a machine for circulating lubricating oil between the housing and the machine whereby the lubricating oil is directed between the journal and the journal-engaging member. An electric motor drives the rotatable shaft relative to the housing. An electrical sensor indicates the electrical input to the motor to determine the quality of lubricating oil from the torque required to rotate the shaft relative to the housing against the friction between the journal and the journal-engaging means.
