Worm fault sample table.

Working condition	State type
	Normal state	Worm axis offset fault status	Coupling looseness fault status		Flat key wear fault status		Poor bearing assembly fault status
			The contact surface in the coupling is worn	Deformation of quincunx star elastic bond	The flat key locating hole is worn	Wear of flat key surface	Bearing assembly clearance is too large	Poor bearing lubrication
