- Efficiency
With new helical-worm gear units the tooth flanks are not completely smoothed down. The efficiency is lower than after the running in process. For a two start worm the decrease is about 6%. The running-in process is essentially concluded after 24 hours. The rated efficiencies are achieved if:
- the gear unit has been run in completely,
- the gear unit has reached the nominal operating temperature,
- the recommended lubricant is used,
- the gear unit is working with rated load.
