Claims
- 1. A method of mounting a motor to a motor support so that the motor will be torsionally flexible relative to the support, and wherein the motor is inflexibly interconnected with a first end of at least two torsionally flexible leaf spring mounting arms that are self-supporting unitary structural members, each having at least one mounting hole at a second end thereof remote from the motor; said method comprising aligning a mounting hole at the second end of a first one of the torsionally flexing mounting arms with a first mounting location on the motor support, and tightening a first fastener at the first mounting location while the fastener is accommodated in the mounting hole in the arm; flexing at least one other torsionally flexible mounting arm to align the mounting hole therein with another mounting location on the motor support; and tightening another fastener at the another mounting location while the another fastener is accommodated in the mounting hole in the other torsionally flexible mounting arm.
- 2. The method of claim 1 wherein the flexible mounting arms are each unitary structures, at least two mounting arms each have the first end thereof held in fixed relation to the motor, and the at least two mounting arms each have their second end adjacent to the motor support, with a mounting hole in each second end constituting means for promoting flexing movement of each arm when subjected to torsional vibrations during operation of the motor; said method including tightening the fastener against a spacer but not tightly clamping the arm, thereby to stiffen the mounting arrangement against vibratory movements in vibrational modes other than the torsional mode, and yet permitting oscillatory movement of the arm about the axis of the fastener during operation of the motor.
- 3. The method of claim 1 wherein the step of tightening the fastener includes compressing a grommet that resiliently yet loosely holds the second end of the mounting arm.
- 4. A method of securing a torsionally flexible motor mounting arrangement to a support wherein the arrangement comprises at least two torsionally flexible steel leaf spring mounting arms each of which are unitary structures, each of which have at least one mounting hole at a first end thereof, and each of which have a second end thereof constrained for supporting a motor; the method comprising locating the mounting hole of at least one mounting arm at a mounting location along the support and constraining such mounting hole to remain aligned at such location; flexing at least one other mounting arm torsionally along its length and thereby aligning the mounting hole therein with another mounting location along the support, and thereafter constraining the mounting hole in the at least one other mounting arm to remain at the another mounting location.
- 5. The method of claim 4 wherein the flexible mounting arms are each unitary structures, and wherein the mounting holes constitute means for promoting flexing movement of each arm along its length when subjected to torsional mode vibrations during motor operation; said method further including constraining a fastener against a spacer trapped in each given mounting hole, but not tightly clamping the arms against the support, thereby to stiffen the mounting arrangement against vibratory movements in vibrational modes other than the torsional mode, and yet permitting oscillatory movement of the arms about respective axes at the respective mounting holes therein.
- 6. The method of claim 5 wherein the step of constraining a fastener includes compressing a grommet that resiliently yet loosely holds the end of a mounting arm in the vicinity of the mounting hole therein.
- 7. A method of mounting a motor to motor support means so that the motor is torsionally flexible relative to the support means, with the motor interconnected with the support means through at least two torsionally flexible mounting arms that each have at least one mounting hole at an end thereof remote from the motor and adjacent to the support means, and with the mounting hole in each end of the at least two torsionally flexible mounting arms permitting oscillatory movement of each arm relative thereto when the arms are subjected to torsional vibrations during operation of the motor; said method including fastening each of the at least two torsionally flexible mounting arms to the support means with a respective fastener accommodated in the mounting hole in the end of the mounting arms; said method further including utilizing a spacer at each fastener location, tightening each fastener against a respective spacer, and utilizing the respective spacers to prevent clamping the respective arms so tightly to prevent oscillation of the arms about the fasteners during motor operation, thereby to stiffen the mounting arrangement against vibratory movements in vibrational modes other than the torsional mode, and yet permitting oscillatory movement of the respective arms about the axis of the fastener during operation of the motor.
- 8. The invention of claim 7 wherein the method further includes: utilizing a grommet with each spacer, and compressing a grommet with each fastener thereby to stiffen the mounting arrangement against vibratory movements in vibrational modes other than the torsional mode and yet still permit oscillatory movement of the respective arms about the axis of the fastener during motor operation.
- 9. A method of securing a torsionally flexible motor mounting arrangement to a support wherein the arrangement comprises a motor and at least two torsionally flexible mounting arms that are each unitary structures, that are each tightly fastened at a first end thereof to prevent movement of such first end relative to the motor during normal motor operation, and that each have at least one mounting hole at a second end thereof for use in establishing a pivotal mounting on support means; said method including: constraining each fastener against a spacer disposed in each given mounting hole, but not tightly clamping the arms against the support, thereby to stiffen the mounting arrangement against vibratory movements in vibrational modes other than the torsional mode, and yet permitting oscillatory movement of the arms about respective axes of the respective mounting holes therein.
- 10. The method of claim 9 wherein the step of constraining each fastener includes compressing a grommet that resiliently yet loosely holds the end of a mounting arm in the vicinity of the mounting hole therein.
- 11. A method of mounting a motor to a motor support so that the motor will be torsionally flexible relative to the support, and wherein the motor is interconnected with one end of each of a plurality of generally radially extending torsionally flexible mounting arms each of which are unitary leaf spring structures formed from flat sheet material and each of which include a spacer accommodating hole at an end thereof particularly adapted for securement to support means; said method including: disposing the motor relative to the support means so that flat leaf spring portions of the plurality of arms each project radially from the motor and extend to mounting locations on the support means, and fastening a support mounting end of each arm of the support means sufficiently tightly to hold the motor rigidly in place with respect to movement in tilting, axial, and radial modes, and yet loosely with respect to torsional mode motor vibratory movement so as to permit torsional mode motor vibration induced flexing of the mounting arms to cause oscillatory pivoting of the arms about the fastened support mounting end of each arm whereby flexing of the leaf spring portions of the mounting arms is enhanced.
- 12. The method of claim 11 further including fastening the support mounting end of the arms at points tangentially offset from radial extensions of the radially extending leaf spring portions of the arms.
