Nautilus bearing the prominent characteristics


The bearings for the back to back configuration of tapered roller bearings, with the larger the contact angle (45). Which not only single bearing spindle configurations possible, while significantly reducing the traditional design of the drive chain length so compact wind turbine designs. Of course, the special design also ensures the bearing or drive all the features
1 larger contact angle
The traditional pairing (or double row) tapered roller bearings, the contact angle is generally only 20 or so, to ensure its larger radial load capability, bearing axial load carrying capacity and the ability to withstand the overturning moment has certain limitations. Therefore, to ensure that a spindle designed to meet the application requirements, there must be another as a second pivot bearing to bear additional radial force, and the two bearing configurations, to meet the axis when subjected to the overturning moment , no deformation.
The Nautilus Stainless steel slewing bearing contact angle break through the traditional design, the contact angle of each single bearing enlarged to 45. With conventional dual bearing configuration comparison, Nautilus bearing two single bearing contact points of connection is much higher than the normal distance between the tapered roller bearing, which connect two points of contact can be used as the point of intersection of two entire shaft a focus, a support shaft running spots.
2 segmented plastic cage
In addition to the larger contact angle, but the bearing Another notable feature is the use of segmented plastic cage. Internal parts of the bearing, the rolling bearing is an important component, in addition to maintaining the roll cage operating state, there are separate to avoid their mutual rolling friction function. Cage is not a force element, can not afford any form of force. Accordingly, it is often used to produce lighter material, while maintaining the frame material to meet another requirement that sufficient strength. Since the operation of the bearing cage rotation power needed is provided by the rolling body, therefore, the holder of the material requires a certain strength to ensure its normal operation.
For SKF Nautilus bearing, in order to ensure that the contact angle connection enough to withstand the force system, bearing sizes are often very large, more applications currently on the market with a diameter of 2 ~ 2.5 m of bearing products. Therefore, reducing the weight bearing itself as its design need to overcome technical problems. As part of the inner and outer bearing rings and rolling elements, in order to ensure that the bearing capacity, in the selection can not have the slightest careless. SKF Nautilus bearings of plastic, not only to ensure adequate strength and weight, to ensure the rotation of the bearing performance, while reducing friction within the bearing.
