Dental turbine spindle assembly |
摘要 |
A dental turbine spindle assembly has a housing in which a pair of bearing supports are disposed concentric with an axis. A pair of bearings are disposed on the supports. A hollow spindle concentric with the axis is carried in a portion of the bearings and at one end projects through an opening in the housing. The projecting portion of the spindle is conical, is split and is threaded. A nut on the projecting portion is conical and is threaded to engage the spindle and has a circular portion partly disposed within a portion of a bearing. There is a wrench-receiving contour at the other end of the spindle accessible through an aperture in the housing.
