Hansen QHPF1 User Manual

6.7. LUBRICATION AFTER INSTALLATION
After levelling, alignment and securing, the gear unit must be lubricated. All instructions mentioned in
chapter 7 "LUBRICATION" must be followed up.
If a long period of standstill is expected before starting up the gear unit, the instructions mentioned in
paragraph 12.6 "EXTENDED PERIODES OF STANDSTILL" must be followed up.
7. LUBRICATION
Lubrication serves four main functions :
- prevents metal to metal contact in gears and bearings
- reduces friction losses
- dissipates the generated heat from gears and bearings
- prevents corrosion
Different lubrication systems can be used, depending on
- gear velocity
- gear unit mounting position
- operating conditions
Hansen Industrial Gearboxes use one of following systems :
- splash lubrication
- forced feed lubrication: - circulation lubrication
- pressure lubrication
These systems can be completed with auxiliary cooling in different forms (see chapter 9: "COOLING").
