Wear Inspection on Small Worm and Wheel Teeth

Engineering note: Wear should be judged as a mesh condition, not only by looking at one component. Tooth polishing, pitting, scoring, material transfer, plastic deformation and uneven contact can point to different causes.Selection media for the relevant worm or wheel...

Mounting and Bearing Datums for Micro Worm Shafts

Engineering note: The worm tooth geometry can only work as intended if the shaft is located consistently by its bearings and housing. Journal diameter, shoulder position, runout and bearing span therefore matter to the gear mesh.Selection media for the relevant worm...

Selecting a Worm Pair for a Small Gearmotor

Engineering note: A small gearmotor stage combines motor characteristics, worm geometry, wheel ratio and the mechanical load. Treating the worm pair as an isolated component can lead to poor thermal or performance decisions.Selection media for the relevant worm or...

Reducing Noise in Small Worm Gear Drives

Engineering note: Worm drives can run smoothly, but noise in a small assembly can come from tooth finish, pitch error, bearing condition, housing resonance, misalignment, motor commutation and lubrication.Selection media for the relevant worm or wheel family. Final...
