Definitions

  • the present invention relates to a gear unit and particularly but not exclusively to a gear unit for a wind turbine.
  • a basic characteristic of a planetary gear stage is that it can contain only a very limited quantity of oil. A minimum quantity of oil however is required in the lubrication system of the gear unit to ensure that the oil does not degrade too fast and oil change intervals are maximized.
  • gear unit housing As the oil reservoir : the oil is continuously churned around which leads to efficiency losses and high cold-start torques, as well as possibly faster oxidation because of a more intense contact of the oil with air, foam building that can disturb lubrication systems and for instance oil level alarms, etceteras.
  • Gear units typically contain several oil pockets that are hard to flush when the oil is changed. Also, contamination of the oil bath due to a failing component may easily lead to consequential damage of other components as the particles from the failing component are coming in the common oil sump of the gear unit.
  • the present invention provides a novel solution for the specific problems mentioned above.
  • the basic idea of the present invention is to completely eliminate the oil sump in the gear unit.
  • a seperate oil reservoir is installed, from which well conditioned (cooled and filtered) oil is fed to the gear unit.
  • central lubrication systems exist that provide oil for instance to different gear units in the same plant or even to a single gear unit, these gear units mostly still also need to enjoy the benefit of their own oil baths.
  • external oil reservoirs which in general would be regarded as contrary to the objective of compactness, is not known in wind turbine gear unit design.
  • Eliminating the oil bath in the gear unit as a whole however can solve a number of the issues mentioned above.
  • the uncoupling of the gear unit lubrication circuit from the oil conditioning circuit by means of an external oil reservoir moreover simplifies the monitoring of the oil conditioning equipment itself, such as oil heaters, cooling systems and filter systems.
  • the gear unit is constructed in such a way that the main gear stages are forming seperate modules, each of which receives fresh conditioned oil from the lubrication system and returns the used oil seperately to the external oil reservoir.
  • This has the advantage that contaminating particles in one of the modules, for instance created by a failing component or by external factors such as dirt or water accumulation, are not allowed to contaminate the other modules, but are intercepted by the separate oil conditioning system of the reservoir.
  • Each of the return lines can be provided with a debris trap device for instance by means of a transparent small reservoir provided with a magnet and allowing visual inspection of the presence of particles or debris.
  • the present invention also proposes to use an oil reservoir that can be easily removed from the nacelle and replaced by another fresh oil reservoir that contains well conditioned oil.
  • This exchange may include the most important parts of the oil conditioning unit such as heaters, coolers and filtration systems.
  • the lubrication system thus receives a complete "reset" at any oil change, removing all possibly accumulated dirt or debris and also avoiding time consuming flushing of oil tanks on-board of the nacelle. Against a background of a growing off-shore market for wind turbines that are even more difficult to service, this may be a large advantage.
  • Figure 1 shows a schematic diagram of cross-section of a gear unit and plural lubrication circuits A, B, C and each serving a different module of the gear unit.
  • the shown gear unit consists of three modules comprising two planetary gear stages 1 and 2 and a helical high speed gear stage 3.
  • the wind turbine rotor bearing arrangement is integrated in the gear unit.
  • Fresh oil is fed from the external reservoir 4 by means a pump 6 and via a flow distributor 7 to the three different modules of the gear unit, and returned from these modules back to the reservoir.
  • the reservoir is provided with a separate oil conditioning circuit 5.
  • the invention with a dry sump offers the additional advantage that the sealing arrangement which has to be provided at a very large diameter, does not have to seal of against any hydrostatic pressure that would be present in case of an oil sump, and can therefore be based on non-contacting sealing principles.
