Actuator Motor Planetary Gear System
ASCO Sintering Company, Commerce, CA. won an award of distinction in the ferrous category for a planetary gear assembly system used in a four wheel drive computer controlled shifting system. The output shaft links the actuator motor to the vehicle transmission and facilitates effortless change from two to four wheel drive in trucks and sport utility vehicles. The other end supports a planetary gear system that supplies torque to operate the control system. The shaft output operates with 16 P/M planet gears and 3 P/M gear carrier plates. The shaft is made from a proprietary high impact copper steel to a density of 7.7 grams/cc. It has an unnotched Charpy impact strength above 136J (110 ft-lbs), elongation greater than 8% and a tensile strength of 65 MPa (95,000 psi).
