F A Q
1.What should I do in case of an oil leak?
- Check the oil quantity
- Check the seal and replace as necessary
- Has the transport securing device of the vent been removed?
- Has the gear unit been mounted in the correct version
- Check the installation location (impermissible ambient temperature, for example from direct sunlight, may lead to damages on the seals)
- Check the ambient conditions (foreign particles in the immediate vicinity may lead to leakage at the seals)
- Check the gear unit temperature (an impermissible gear unit temperature may lead to excess pressure in the gear unit and therefore leakage)
- Were suitable radial shaft seals used for the application (e.g. use version with dust lip in dirty environments)?
2. What should I do if the temperature of my unit increases?
- Check the oil quantity
- Has the gear unit been mounted according to the correct verion
- Check the installation location – is there unavoidable ambient temperature, for example, from direct sunlight?
- Check the motor speed – speeds too high overload
3.What should I do if I hear unusual noises while the machine is running?
- Check the oil quantity
- Check the oil condition (oil analysis)
- Change the oil as required
- Check the gear unit fastening/base
- Check whether the noise results from the application itself or whether it is caused by the application (resonances)
- Check the application for excess load (damage to bearing/gearing)
- Disassemble the motor from the gear unit and check the motor separately to narrow down the source (note: a new seal may be required!)
4.What should I do if there are an increased amount of vibrations?
- Check the gear unit fastening/base
- Check the coupling (if present) and adjust as necessary
- In case of operation with a variable frequency drive (VFD), check the VFD’s parameters and match it with the motor data
- Check whether the vibration results from the application itself (resonance frequency)
- Match the vibration frequency to the source (e.g. high-frequency vibrations indicate the motor or the input shaft)
- If necessary, carry out a vibration analysis by qualified personnel
