forming the noise reducer 10 of lubricomp nylon 6 6 w 10 aramid fibers amp 10 ptfe results in a sideways force of about 0 40 lbs and forming the noise reducer 10 of ultramid 35 glass filled nylon 6 6 results in a sideways spring force of about 1 2 lbs that is with a deflection of 0 04 inches 1 mm the preferred shape results in spring constants of about 9 pounds per inch delrin and lubricomp to about 30 pounds per inch ultramid by molding the noise reducer 10 out of a polymer material the noise reducer 10 can be easily formed at low cost while providing the design flexibility needed to mate with various motors used in hvac actuators and achieve desired spring forces on the motor shafts the amount of noise reduction achieved by the noise reducer 10 should be audibly perceptible such as a reduction of at least 3 db and more preferably a reduction of at least 5 db the preferred embodiment reduces the noise output of the actuator 14 by about 10 to 15 db or more while various causes internal to the motor 12 may contribute to the sound output of the motor.
