WORM SCREWS

Calculation of lubricant consumption during worm screw lubrication

Lubrication of the worm screws is necessary to reduce the friction of the teeth and to facilitate their movement. For this purpose, it is necessary to provide an adequate amount of lubricant between the parts in contact.

REMARKS AND ADDITIONAL NOTES
The lubricant values calculated with the previous formulas have the indicated value and in any case are valid for:
- Automatic Plant
- Continuous service
- Normal operating conditions

Please note that this volume may be affected by heavy-duty operating conditions and in any case by the following factors:
- Impact and/or Heating
- Speed of the part to be lubricated (number of revolutions or number of strokes per hour)
- Specific pressure between contact surfaces
- Presence of dirt, water ingress, contaminants

It is possible to apply corrections to the lubricant supply (service factor) in the presence of special conditions, due to environmental situations or specific to the part to be lubricated. Specifically:
- 0,5 for intermittent service
- 1.0 for continuous service (considered in this specification)
- 2.0 for medium-heavy continuous service
- 4,0 for heavy-duty continuous service
