Latest Patents

Kellstrom's latest patents include innovative designs for roller skew control in tapered roller bearings. One of his patents describes a tapered roller bearing that features inner and outer members along with frusto-conical rolling elements. This design incorporates means for controlling the skew angle of the rolling elements during operation, which helps to lower overall friction and increase the service life of the bearing. The profiles of the rolling elements and raceways are specifically designed to allow for skewing at a predetermined angle, enabling the rolling elements to slide relative to the raceways during operation.

Another patent focuses on roller bearings that comprise rollers with a positive skew angle. This design includes inner and outer members with raceways that define an annular space for the rolling elements. The rolling elements are engineered to engage the members at contact zones, and the design allows for a non-negative skew angle within a predetermined range. This innovative approach ensures that the friction forces arising from the skewed roller position work to reduce the magnitude of the normal contact forces between the roller and raceways.
