FAQs: Gear Components for Automation Applications

For gearbox components, we consistently meet tolerances as close as ±0.001 inches on the overall dimensions of housings and on the dedicated mounting features, achieve bearing bore concentricity of 0.0005 inches for input and output shafts while preserving the gear mesh geometry, and maintain center distances between gear axes within ±0.0003 inches for proper tooth engagement and minimal backlash. The perpendicularity of mounting surfaces within 0.002 inches allows for accurate motor and robot assembly with no misalignment. Bearing seat diameter tolerances of H7 or tighter are appropriate for press fit, transition fit and bearing application. Seal grooves for O-ring compression are within ±0.002 inches. Mounting flange bolt circle diameters are ±0.005 inches for proper interchangeability. There is a tolerance of 0.001 inches between parallel faces on split housings, which aids in proper clamping and sealing. This is done so that the gearboxes maintain a rated efficiency of over 90% for planetary, 95% for parallel shafts, operate noiselessly under 70 dB at rated speed and load, and tether with a temperature-stable service life of over 20,000 continuous hours. The geared units will hold the lubricant viscosity within the optimal range and adjust dynamically according to the gear load.

For gear hobbing, an industry tool, rotational hobbing, employs multiple rotary hobs to manufacture multiple gear forms in differential configurations, producing involute profiles with a pitch accuracy of ±0.0005 inches, for modules ranging from 0.5 to 12. Internal gears and splines are shaped with machine gear shaving, in which a reciprocating gear cutter performs the task. Post gear honing, which aims to create super-finished surfaces to minimize noise during operation, gears are hardened and carburized with a case depth of 0.8 to 1.5 mm and a surface hardness of 58-62 HRC. Teeth accuracy for gear grinding is achieved within 5 microns, correlating to the final gear quality after heat treatment, subsequent to DIN 4 and AGMA 12 quality specifications. For CNC turning, gear blanks are produced with key holes and high precision mounted-features.

Alloy steels such as 4140 and 8620 have commendable attributes such as perfect strength for torque transmission with ability for carburizing to achieve surface hardness of 58-62 HRC while a core remains tough, fatigue resistance for several million load cycles, and cost efficiency for industrial gears. Tool steel S7 imparts maximum toughness to resist tooth breakage under shock loads, and through-hardening with superior abrasion resistance. Stainless steel 17-4 PH has the needed strength for precipitation hardening and meets food grade standards. For corrosion resistant wash down applications, and for other applications, it offers sufficient strength and corrosion resistance. Brass C36000 is self-lubricating, operates quietly, and has user friendly properties for the manufacture of worm wheels. Engineering plastics such as Delrin and nylon have lightweight construction, and for vibration attenuation, corrosion resistance, and quiet operation, as well as lubrication-free operation, are superior to other materials.

Automation gear components entail highly accurate power transmission components which move and shift torque within robotic drives, motor gearboxes, and positioning systems. There are various types of these components. These types include spur gears which have straight teeth designed for parallel shaft applications, helical gears which have teeth placed at angles designed for smooth and quiet operational shifts, bevel gears meant for crossing shaft angles, worm gears which have high reduction ratios, compound planetary gears designed for high-torque applications, internal ring gears, gear racks which convert and drive linear motion, timing gears which control and drive synchronized motion, and other custom designed gears such as cycloidal drives, harmonic drive components, and precision instrumentation drives.
