Patent ID: 8468676

Claim:
A method for mounting a rotor to a motor shaft, the motor shaft having a circumference defined by a substantially maximum radius of the motor shaft such that the circumference is substantially circular, comprising: (a) selecting a rotor having a central bore with a diameter larger than a motor shaft, a first axis passing through a center point of said central bore, a first bore having a center point, said first bore being adjacent to and adjoining with said central bore, a second bore having a center point and being adjacent to and adjoining with said central bore, and having an angle made between said center point of said first bore, said center point of said central bore, and said center point of said second bore, wherein said angle is selected from the group consisting of acute angles, right angles, and obtuse angles; (b) inserting a first monolithic fastener having a first threaded shaft and a camming action in said first bore such that a cam portion of said first monolithic fastener is clear of said central bore and said first monolithic fastener is disposed within said first bore; (c) inserting a second monolithic fastener having a second threaded shaft and a camming action in said second bore such that a cam portion of said second monolithic fastener is clear of said central bore and said second monolithic fastener is disposed within said second bore; (d) positioning said rotor on the motor shaft as the motor shaft passes through said central bore of said rotor; (e) rotating said first monolithic fastener in a first direction such that said cam portion of said first monolithic fastener clamps against the circumference of the motor shaft along a portion of a surface of the motor shaft coincident with the circumference of the motor shaft; and (f) rotating said second monolithic fastener in a second direction, that is opposed to said first direction, such that said cam portion of said second monolithic fastener clamps against the circumference of the motor shaft along a portion of a surface of the motor shaft coincident with the circumference of the motor shaft.
