Gear backlash is a vital design parameter instead of a defect; only reasonable controlled backlash is required instead of full elimination.
Proper backlash ensures lubrication film, absorbs thermal expansion, offsets assembly deviation and relieves load deformation. Excessive backlash causes positioning error, vibration and extra dynamic loads, damaging precision transmission.
Engineers configure backlash based on load, speed, temperature and accuracy for heavy-duty custom gear systems.
