Inspection – drive units
Roller chain transmission
The roller chain transmission should be checked and
lubricated after 50, 250, 500 hours of operation, and then
every 500 hours.
If the roller chain transmission is not fitted with a chain
tensioner the chain tension should be checked on this
occasion.
At the same time as the roller chain tension is
checked, the chain must also be lubricated with a suita-
ble chain spray or similar.
If the transmission is fitted with a chain tensioner,
lubrication should only be carried out at the stated inter-
vals. The condition of the chain tensioner must be
checked at the same time as the lubricating is done.
Note
The discs in the slip clutch must be kept free from oil and
grease.
Worm gear motor and geared motor
The worm gear or geared motor is checked in accord-
ance with the instructions from the relevant supplier.
Guide for the conveyor chain
The purpose of the guide for the conveyor chain is to
guide the return chain correctly into the drive unit.
Fully enclosed drive units do not have guides. On
these, no slack is permitted at the drive unit since the
conveyor chain is being controlled all the time. Special
attention must be given to chain elongation in conveyors
of this configuration.
If guides are fitted they can be of two different types:
• Loose disposable guides in plastic.
• Guides integrated into the ends of the drive unit...
General checks on drive unit
Carry out a general inspection of the drive unit.
• Check particularly that the protective covers for the
roller chains are complete and firmly in place.
• Replace damaged/worn parts.
Replaceable chain guides
Chain guides integrated into ends.
