ABSTRACT:
A rolling bearing type traction wheel and hub assembly which is especially adapted to ride upon either flat (i.e. horizontal) or laterally sloping surfaces such as trolley trackways and/or the opposite side flanges of supporting I-beams or the like; the axis of wheel rotation being in any case canted relative to the support surface. The wheel assembly comprises a generally cylindrical shaped inner bearing race/hub member which is fixed to an external support and is encircled by a rotatable outer race/wheel member, with rolling bearings enclosed therebetween. The wheel and hub parts are formed of sheet material and are so shaped as to novelly facilitate initial assembly thereof. When the device is operating under load the parts automatically float into self-aligning operational relationship and are retained in proper operative relationship without need of any auxiliary retention device.
