\nWhat is the difference between backlash and positioning repeatability?<\/h3>\n

Backlash is a mechanical property of the gearbox \u2014 the angular clearance between gear teeth. Positioning repeatability is a system-level property of the complete servo axis \u2014 the ability to return to the same commanded position after multiple approach cycles. A servo axis with a closed-loop linear scale encoder can achieve sub-micron repeatability even with a P2 (5 arcmin) gearbox, because the encoder compensates for backlash through closed-loop feedback. Backlash matters most when: (1) the servo uses motor encoder feedback only (not output-side encoder), or (2) the axis must maintain accuracy through power-off events, or (3) the system must achieve accuracy in both approach directions without reversal compensation. For applications using output-side linear scale encoders, backlash grade selection has negligible effect on positioning repeatability \u2014 the encoder compensates it.<\/p>\n<\/div>\n

\n

Ot\u00e1zka<\/span>
\nWhy does my P0 gearbox show more than 1 arcmin backlash after 3 years of operation \u2014 is it defective?<\/h3>\n

Not necessarily. Backlash growth from \u22641 arcmin at delivery to 1.3\u20131.5 arcmin after 3 years (approximately 7,500 operating hours at three-shift operation) is within the expected wear profile for P0 gearboxes. The service life target of \u22642 arcmin at 20,000 hours means some measurable growth is expected during service. Compare the measured value to the delivery certificate \u2014 growth within 1.5\u00d7 the delivery value is normal wear, not a defect. If the growth is rapid (reaching 1.5\u00d7 in less than 3,000 hours), investigate: the gearbox may have been operated above rated torque, the inertia ratio may be excessive, or the shaft seal may have failed allowing contamination into the grease.<\/p>\n<\/div>\n

\n

Ot\u00e1zka<\/span>
\nHow does a worm gear reducer specify backlash, compared to planetary P0\/P1\/P2?<\/h3>\n

Worm gear reducers use a fundamentally different approach to positioning control: the worm mechanism’s self-locking property provides position holding without needing tight tooth clearance, and the sliding contact geometry makes sub-5-arcmin backlash impractical to manufacture at reasonable cost. Most worm reducer catalogues do not specify backlash in arcminutes at all \u2014 they specify “tooth contact ratio” or simply note that the design is “backlash-minimised.” When backlash is specified for z\u00e1vitovkov\u00e9 reduktory<\/a>, values of 10\u201330 arcmin are typical. This is why worm reducers are not used for any servo axis where closed-loop positioning in both directions is required \u2014 the backlash budget simply does not allow it. The P0\/P1\/P2 grading system is specific to precision planetary (and some precision helical) gearboxes where rolling-contact gear geometry makes sub-3-arcmin backlash manufacturable and economically viable.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
