ABSTRACT:
A cycle wheel mounting fixture for a dynamic balancing machine includes a first cone that is axially slidable on the spindle of the balancer, with its apex facing towards the distal end of the spindle, to engage the inner surface of a cycle wheel hub. This cone is biased away from the flange by a spring interposed between the flange and the cone. One or more resilient pressure rings surround the spring and cone and bear against the spokes and hub of the wheel. An outer cone engages the outside of the wheel hub and centers the wheel on the spindle along with the inner cone. The bias provided to the inner cone allows it to engage the wheel with adequate supporting pressure but without exerting any damaging forces thereon. The resilient support provided by the pressure rings assures a firm mounting of the wheel on the spindle so that the two rotate in unison without any oscillation that could adversely affect the balance measurement.
