Rust
ASSUMED CAUSE
Backlash, torsion, deflection in
input system
Loose linkage in input system
Rotation lag in input system
Insufficient motor power
Clutch brake timing
Cam flaking
Rotating components are
physically unbalanced
Rotating components are eccentric
Insufficient torsional rigidity in
output system
Momentum in output system is too
intense
Frame deformity
Heat caused by agitation
Rotating speed too high
Too much preload
Insufficient lubrication
Broken sealing device
Broken O-ring
Lubricating oil splashes
Starting hole for tapping goes all
the way through
Damage due to material fatigue
Shock load
Fretting corrosion
Ambicient conditions

Repairs and maintenance
CORRECTION
Check input drive system
Change linkage elements, tighten bolts
Change rotation transmission component
Increase motor power rating
Adjust timing cam
Replace cam, reduce load on output shaft
Balance components
Align centers
Increase rigidity of output system
Select a larger indexing drive model
Increase rigidity of mounting base
Check lubrication oil level and viscosity
Adjust eccentric flange
Check lubrication
Check lubrication
Replace sealing device, install dust cover
Replace parts
Change oil plug part number
Apply sealant to mounting
Reduce overhanging load
Install torque limiter on output shaft
Change friction linkage
Apply rust inhibitor or paint surface
