Machine for testing and comparing bearings and bearing materials

摘要

A machine for testing and comparing bearings of the plain or sliding type and bearing materials comprising one or a pair of bearing test stations each having a test bearing housing for fixedly retaining a selected test bearing. A rotatably driven shaft is journalled in the test bearing. Means are provided for applying a predetermined load radially on the test bearing in the housing and means are also provided for measuring the friction force generated by rotation of the shaft in the test bearing, whereby the coefficient of friction of the test bearing can be determined. Means are also provided for damping oscillations occurring in the test bearing housing and for limiting rotation of the test bearing and housing under excess generated friction force.
