Description

All DCL electric actuators uses special formulated copper alloy worm gear. Worm gear is monolithic casting with this material instead of plating copper on the surface, which increases its overall strength and abrasion resistance ability.

The easiest broken part for electric actuator is the last stage worm gear or spur gear, because it is close to the output drive and suffers the biggest torque and friction. So last stage worm gear directly influences the operation life time of actuator. So DCL designs large worm gear with longer radius(arm) to make the force on wheel teeth less, when same torque added. Moreover, instead of plating copper to the surface, DCL actuator’s whole worm wheel is definitely totally built by bronze alloy.

Gear runout also affects the transfer noise and mechanical life. DCL has a very professional SQE team to control parts quality from suppliers. Every cover, bearing, gear and electronics must be tested before receipt to warehouse.
