How to Specify Worm Gear Center Distance

Engineering note: Center distance is the installed distance between the worm axis and wheel axis. In a replacement mechanism, it is one of the most important dimensions because the housing often fixes it.Selection media for the relevant worm or wheel family. Final...

Pressure System and Tooth Compatibility in Worm Pairs

Engineering note: Two components that share module are not automatically a compatible worm pair. The pressure system, tooth form, starts, hand, center distance and mating design must agree.Selection media for the relevant worm or wheel family. Final production...

Backlash in Micro Worm Gear Mechanisms

Engineering note: Backlash is the free angular or linear movement that appears when the direction of motion reverses before the mating teeth fully transfer load in the opposite direction.Selection media for the relevant worm or wheel family. Final production geometry...

Lead Angle and Micro Worm Gear Performance

Engineering note: Lead angle describes the helix progression of the worm and influences sliding, efficiency, axial force and backdriving behavior. It changes with worm geometry and the number of starts.Selection media for the relevant worm or wheel family. Final...

Material Pairing for Small Worm Drives

Engineering note: Worm drives operate with substantial sliding contact, so the worm and wheel are normally selected as a material pair rather than as two independent gears.Selection media for the relevant worm or wheel family. Final production geometry is confirmed...
