NetShape Technologies Inc., Cambellsburg, Ind., captured the second award of distinction in this category for a differential carrier gear made for Ariens Co., Brillion, Wis. The net shape part goes in a transmission for the Ariens professional Snothro line of 8.5-hp and higher snow blowers. The design improved drive torque output by speeding up the pinion and increasing the ratio after the friction disc in the transmission. The gear enables remote locking and unlocking of the differential. The complex five-level part has density of 6.8 gm/cm3, a minimum tensile strength of 75 kpsi, a transverse rupture strength of 130 kpsi, a yield strength of 90 kpsi, and a fatigue limit of 34 kpsi. Parts need secondary quenching and tempering.
