First Claim
Patent Images
1. A method for reducing roller skew for a plurality of rollers configured to support a rotary body, the method comprising:
- ascertaining a first thrust load property applied to a first roller of the plurality of rollers from the rotary body while the rotary body rotates in a first rotational direction;
ascertaining a second thrust load property applied to the first roller from the rotary body while the rotary body rotates in a second rotational direction that is opposite of the first rotational direction; and
adjusting an orientation of at least one bearing assembly for the first roller until an amplitude difference between the first thrust load property and the second thrust load property is below a predetermined threshold.

Abstract
A system and method for reducing roller skew, which involve ascertaining first and second thrust load properties applied to a roller while a rotary body rotates in opposing rotational directions, and adjusting an orientation of at least one bearing assembly for the roller until an amplitude difference between the first and second thrust load properties is below a predetermined threshold.

8. A method for reducing roller skew for a plurality of rollers configured to support a rotary body, the method comprising:
-
(a) rotating a rotary body in a first rotational direction, which places a first thrust load on a first roller of the plurality of rollers; (b) switching the rotational direction of the rotary body from the first rotational direction to a second rotational direction that is opposite of the first rotational direction, which places a second thrust load on the first roller; (c) adjusting an orientation of at least one bearing assembly for the first roller to reduce a difference in amplitude between the first thrust load and the second thrust load; and (d) repeating step (a), step (b), step (c), or combinations thereof until the difference in the amplitude is below a predetermined threshold. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for reducing roller skew for a plurality of rollers configured to support a rotary body, the assembly comprising:
-
at least one sensor securable to a bearing assembly of a first roller of the plurality of rollers, the at least one sensor being configured to measure a property corresponding to a thrust load applied to the first roller from the rotary body; and a computer-based system in signal communication with the at least one sensor, and configured to monitor the property measured by the at least one sensor while the rotary body rotates in a first rotational direction and in a second rotational direction that is opposite of the first rotational direction. - View Dependent Claims (15, 16, 17, 18, 19, 20)
