Test apparatus comprises a wheel means including a hub and wheel web rotatably mounted on wheel bearings set in the wheel hub and mounted on a non-rotatable axle mechanism. The wheel means is rotatable by motor means. A load application mechanism including hydraulic load cylinders and load sensors effects selective imposition of radial, axial and moment loading upon the wheel web, wheel hub and wheel bearings so that the bearings experience operting conditions during rotation and at rest. Acoustic sensing means enable determination of the onset of bearing failure. Operation of test apparatus is preferably controlled by a computer.

Apparatus and method for testing wheels, bearings and lubricants

Cut tree holder

A rim for a wheel and brake assembly having a lug on the radially inner surface integral with the rim and positioned for torque transmission between axially slidable brake members and the rim. The lug has an inner face spaced from the radially inner surface of the rim and is recessed at a position along the lug with the thickness of the lug at the recess being less than at other positions along the lug to reduce the stresses in the lug and rim.
