Let me start by covering a little bit about bearings in general. Wind
turbine bearings need to be corrosion resistant due to their constant
exposure to the elements. The reason for this is that it allows the
inner and outer rings of the bearing to appear with a slight slant and
they are out-of track in relation to each other without damaging the
bearing while running.
With the spherical bearing you will find that it
has two sets of rollers, which both allow for absorption of radial
loads, which come from across the shaft from the weight of the rotor and
shaft etc and from the large axial forces, again across the shaft,
which results in wind pressure on the rotor. In order to ensure that all
wind turbine bearings are corrosion resistant they should come
available with a wide range of surface treatments. With wind turbines
the main bearings are mounted within the bearing housings, which are
bolted to the main frame.
Each of the bearing arrangements that are
available come with their advantages and their disadvantages but the
amount of bearings that you will need is basically calculated through
the amount of wind turbines that you have and the size of these
turbines.The inner and outer rings of the bearing can slant to a maximum
of half a degree. It is highly important that you only enlist the help
of an experienced supplier when it comes to wind turbine bearings due to
their size and their use. This may not sound like a large amount but
this is all that is needed as it is a big enough slant to ensure that
any possible small errors in alignment between the wind turbine shaft
and the bearing housing will not give excessive edge loads, which could
result in possible damage to the bearing. But what exactly should you be
looking for when it comes to wind turbine bearings?Well with all modern
forms of wind turbines you will find spherical roller bearings as the
main bearings that are present. Without this resistance the bearings
ability would be slowly reduced, affecting its performance, which would
then go on to cause the wind turbine to stop working. If for whatever
reason this isnt the case then you should enquire into what forms of
surface treatments are available as the last thing you want to do is
spend a lot of money on your bearings only to find that they need
replacing in a short space of time.
For example if you have a small wind turbine, which includes 150kW then they will be fitted with two bearings. You can tell just how important bearings are for the fact that pretty much any form of machinery or piece of technology that twists or turns probably has a bearing in it. They are highly engineered and precision made components, which enable various aspects to move at high speeds. So what does this mean to you? Well the term spherical means that the inside of the bearings outer ring is shaped to resemble a cross section of a ball. When it comes to wind turbine bearings, the manufacturers need a bearing supplier with experience and capability to support critical pitch, yaw and gearbox applications in systems. If you have 250/300kW however they will only have the one bearing. The quantity of the bearings that are present is gloves making machine Suppliers a factor that varies among the different types of wind turbines that are available.
