ELGA-TB-G/-RF(-F1)
Note
The plain-bearing guide of the ELGA-TB-G does not require lubrication.
For lubrication of the toothed belt axis with roller bearing guide ELGA-TB-RF:
Note
The lubrication interval S
• Cut the lubrication interval S
apply:
– dusty and dirty environment
– nominal strokes  2000 mm
– speeds  2 m/s
– positioning profile: Z delta operation (frequent acceleration and braking)
– ambient temperatures  +40 °C
– product in operation  3 years.
If more than one of the above criteria are met, the normal lubrication interval must be
divided by four.
1. Calculate the load comparison factor fv with
the help of the formula for combined loads
(è 12 Technical data) and determine the
lubricating interval S
2. Lubricate the roller bearing guide at all lubric­
ation holes aB (permissible oil è 10 Accessor­
ies).
Relubrication amount per lubrication hole:
– ELGA-RF-70:
– ELGA-RF-80:
– ELGA-RF-120:
For checking the cover band:
• Check the cover band after every 2000 km of operating distance.
Waves on the cover band are a sign for wear of the band reverser.
• In case of wave formation, tighten the cover band as follows:
1. Loosen screws aF (è Fig. 14).
2. Push the cover band into the end cap.
3. Retighten the screws with 2 Nm.
If the cover band can no longer be retightened, the wear of the band reversers is too great and they
must be replaced (è 9 Repair).
