Title:
LOAD MEASURING DEVICE OF ROLLING BEARING UNIT
Document Type and Number:
Japanese Patent JP2005321236
Kind Code:
A
Abstract:
To provide a structure capable of constituting at low cost, and capable of precisely calculating the load activated between a hub 11 and an outer race 1 regardless of secular change or assemble error.
The revolution speed of balls 8a, 8b constituting each line is detected by a pair of revolution detection sensors 6a, 6b and encoders 10a, 10b for detecting the revolution assembled on each retainer 9a, 9b. The operator calculates the load based on the detection signal of each revolution speed detection sensor 6a, 6b. the operator estimates the preload of each ball 8a, 8b, and corrects the gain performance and zero point based on the estimated value.
