Trouble and Countermeasure of Conveyor Chain

Actual State

Main Causes

Countermeasure

Wearing the Inside of link plate of Chain or the 齒 side of Sprocket.

Badness of Sprocket ALIGNMENT

Tacking off the Chain and retouch the injection of Sprocket axis.

Squeezed in the width direction of Chain

Remove the cause to press and use the guide roller

Vibration of Sprocket

Exchange as new Sprocket

Badness of the rotation of roller

Excess load of Roller

Lubricate between Bush and Roller and Select the proper specification (GT, Bearing, Roller etc.)

Entering the foreign substance into the BUSH/Roller

Remove regularly, and Protect the Chain attaching the partition and Select the specification that the space between the BUSH/roller is large

Piling up the foreign substance on the rail

Remove regularly and Protect the Chain attaching the partition

The Lubricant is entering into the BUSH/roller and attaching on the surface of roller or rail

Select the proper lubricant and method to Lubricate

Rust Sticking in BUSH/Roller

Select the proper specification (KT etc.)

Badness of Winding

Rust Sticking

Protect the Chain attaching the partition and Select the proper specification (MT etc.)

Entering the foreign substance into the PIN/ BUSH

Protect the Chain attaching the partition Select the specification that the space between the PIN /BUSH/roller is large

Winding in the Sprocket of Chain

Increase the Loosing the Chain

Reduce the amount of loosing of Chain or insert the TIGHTENER

Abrasion of Sprocket

Exchange with New Chain

Do not move or roll as hanging in the Sprocket of Chain

It is not suitable the Chain and Sprocket

Exchange the one between Chain and Sprocket

Severe Overload

Reduce the overload as possible as you can (Attaching the shock-absorbing device etc.)

Lengthen as the Chain is worn

Exchange as new Chain.

There is a STICK SLIP)(SURGING) in Chain.

Reduce the Speed

Do High Speed.

Other

Improve the power of FRAME, and Select the surging preventing specification, reduce the loosing of roller Chain for operating

Abrasion of under tooth 齒押面 of Sprocket

Lack of Tooth Chucking Size

Increase the number of teeth.

Other

Use Sprocket or Exchange the Tooth of Sprocket.

Abrasion of the internal link Hole of Block Chain of Pin

Excess of Internal tension

Inject the PLECE into the Sprocket.
Lubricate in both side of Chain and Sprocket.

Noise

Lack Lubrication of BUSH/roller

Lubricate enough and adopt the Bearing, Roller, and Plastic roller

Lack Lubrication of the connection part of PIN/BUSH

Lubricated enough.

Collision of Roller/Sprocket

Lubricate the Sprocket and Adopt the Plastic Roller.
