FAQs: Gearbox Housings for Automation Applications

Gearbox housings are precision enclosures containing and supporting gear trains, bearings, and lubrication systems in motion control applications. Servo gearbox cases for robotic joints and positioning systems, planetary reducers for compact high-torque applications, worm gears for right-angle drives, helical gearboxes for industrial drives, harmonic drives for zero-backlash precision, cycloidal reducers, right-angle gearboxes, split casings for ease of assembly and maintenance, and custom enclosures with modular housings for varied mounting arrangements and integrated motor flanges are some examples.

Aluminum 6061-T6 and A380 die-cast helps cut down the overall weight of the drivetrain by 50 to 65 percent because of the lightweight construction, awesome thermal conductivity helps dissipate the heat produced by the gears' friction at 167 watts per meter-Kelvin, good machinability allows for netshape integration of features, and strength is adequate for the torque of 500 Newton-meters. Cast iron GG25 and GG30 helps lower vibration much more than other options. This helps reduce noise by 5 to 10 dB. It also helps with excellent dimensional stability which helps to prevent warping, and outstanding wear resistance at the bearing surfaces. It is also very cost effective for larger housings. Steel plate is used to provide maximum strength for more heavy-duty applications which helps support torques of over 5000 Newton-meters, and helps with preventing deflection by providing rigidity. Magnesium is used to provide weight reduction; it is 35 percent lighter than aluminum while also providing adequate strength for use in aerospace and mobile robotics applications.

With 3D CNC milled heterogeneous 3D housing designs, mounting bosses, oil passage, and breather ports are even made. Specialty boring machines even attain bearing bores within 0.001 inch tolerances and 0.002 inch concentricity for shaft alignment. Face milled surfaces are flat to 0.003 inches even for motor attachment and output flange mounting surfaces. Seal grooves for oil seals and O-rings are pocket machined to exact specifications. Counter-bores have bolt patterns and lubrication ports drilled on and mounting threads are also created through thread milling. Multiple bearing bores that are line bored have coaxial alignment to 1.0 inches.

Tolerances can be within +/- 0.001 inches for bearing set within bores and equally spaced shaft alignment, concentricity for spaced bearing bores, and coaxial alignment for bores. Mounting surfaces have a concentricity of 0.003 inches to achieve contact flatness for even motor spacing. Seal grooves have a tolerance of +/- 0.003 inches to O-ring for compression. Bolt hole positions have a tolerance of +/- 0.005 inches. For larger castings, the overall housing dimensions can be +/- 0.010 inches to ensure assembly clearances are appropriate and large castings meant for machining.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

Every component is produced and manufactured and certified under the ISO 9001 quality management systems. We certified material traceability including casting certifications, dimensional verification against design specifications, bearing bore and concentricity measurement reports and documented for drivetrain enclosures in industrial automation. Oil seal leak certifications were done under 1 milliliter per hour and were structurally certified for integrity for torques ranging from 10 to 5000 Newton-meters depending on application. Gear alignment within 0.05 millimeters certification was documented.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers
