heat treatment for torque multiplier wrench epicyclic gears

Truck torque multiplier typically employ an epicyclic gear train having 3 stages. Each stage of gearing multiplies the torque applied. The material and fabrication technology of epicyclic gear is fatal to the quality of torque multiplier. Our gears are made of alloy steel 20CrMo and each gears are fully heat treated (see the machine picture), thus ensures high hardness while keeping good malleability, largely increase the output torque and tool’s lifespan.
