Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to produce a huge variety of answers to address the most exceptional bearing challenges, producing Ever-power’s leading supplier of wind turbine bearings. Kaydon has the experience and capacity to support vital pitch, yaw and gearbox applications in devices from 200 kW to 5.0 MW and beyond.
Whether the need is for huge or low wind velocity, terrain based or off shore, 200 kW or 5.0 MW-along with appointment critical customer requirements and industry rules such as those specified by Germanischer Lloyd “Non-Marine Technology-Offshore Wind Strength”-Kaydon’s engineers can fix even the most challenging challenges.
Slewing bearing is identical to regular bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of dissimilarities. Normally, slewing bearing has huge dimensions, OD generally betwwen 0.4m to 10m, plus some even to 40m. Under normal circumstances, slewing bearing functioning in a minimal speed, high load state. Slewing bearing comes with mounting holes, lubricating holes and sealing machine. It has compact stucture, convenience to guide rotate, simple assembly and easy maintenance etc.
Four point speak to – Four point contact ball bearings will be radial single row angular get in touch with ball bearings with races that can support both axial and radial loads in either course. Available with internal gear teeth, external gear pearly whites or gearless designs.
Eight point contact – Eight point speak to ball bearings are radial double row angular contact ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Obtainable with internal gear the teeth, external gear pearly whites or gearless designs.
Three row roller – three row roller bearings are designed with three independent rows of rollers to accommodate a mixture of axial and radial overturning moment loads. Readily available with internal gear the teeth, external gear teeth or gearless designs.
Cross roller – Cross roller bearings are designed with multi-directionally installed cylindrical rollers. They are made to accommodate radial, axial and overturning moment loads with a compact design footprint.
Angular contact – An angular contact ball bearing uses axially asymmetric races. Axial loads complete in a straight collection through the bearing, whereas a radial load normally takes an oblique course that will want to split up the races axially. Therefore the angle of get in touch with on the inner competition is equivalent to that on the outer race. Angular speak to bearings better support “merged loads” (loading in both the radial and axial guidelines) and the contact position of the bearing ought to be matched to the relative proportions of each.
Axial thrust ball bearing – Thrust ball bearings, made up of ball bearings backed in a ring, can be utilized in huge thrust applications where there is certainly high axial load. An axial load is normally transmitted immediately through the bearing, while a radial load is poorly supported and tends to separate the races.
Deep groove ball bearings – In a deep-groove radial bearing, the race dimensions happen to be near the dimensions of the balls that run in it. Deep-groove bearings can support bigger loads.
WireX wire-race turntable bearings
WireX® wire-race bearings
Ever-power bearings were originally designed for military turret applications, where space and weight are at a premium and corrosion resistance is essential. They consist of wire raceways inserted in light-weight support rings, enabling a high load capacity and large diameter in a bearing that can be 60% lighter than one made entirely of steel. EP bearings are custom manufactured to match each design and specification. EP bearings have already been used efficiently in applications requiring a lightweight, corrosion-resistant bearing, which includes turrets, radar, and sonar.
