ABSTRACT:
An angle drive for a surgical power tool comprises a tool housing and first and second shafts rotatably supported end to end in the housing. The shafts have rotational axes which cross at an obtuse angle. Interengaged, opposed bevel gears are provided on the adjacent ends of the shafts for rotating of one shaft by the other. A ball is received in coaxial, frustoconical recesses in the adjacent ends of the shafts to locate one shaft with respect to the other and determine the meshing clearances between the bevel gear teeth.
