Title:
ROLLING BEARING WITH SENSOR AND LOAD CALCULATION SYSTEM
Document Type and Number:
Japanese Patent JP2021004813
Kind Code:
A
Abstract:
To provide a rolling bearing with a sensor or the like capable of obtaining information for stably determining a load regardless of a position of a rolling element.SOLUTION: A rolling bearing 5 with a sensor includes: a rolling bearing 10; and a coil 20 in which a core material is fixed on the side surface orthogonal to the direction of a rotation shaft center Ax of the rolling bearing 10 and around which a conductor wire is wound. Two coils 20 are provided. In two coils 20, a pitch angle P1 centered on a rotation axis Ax, among a plurality of rolling elements 13 having the rolling bearing 10, is 1/2 of a pitch angle P2 of the two rolling elements adjacent to each other in the circumferential direction around the rotation axis Ax.SELECTED DRAWING: Figure 4
