This abstract first appeared for US patent application 20240035906 titled 'LOAD ESTIMATING DEVICE FOR ROLLING BEARING, CONTROL DEVICE FOR MECHANICAL DEVICE PROVIDED WITH ROLLING BEARING, LOAD ESTIMATING METHOD, AND PROGRAM

==Simplified Explanation==

The abstract describes a load estimating device for a rolling bearing. It includes a vibration sensor to measure vibrations of the bearing during rotation, a rotational speed sensor to measure the rotational speed of the bearing, a deriving means to calculate a vibration value for a predetermined frequency using the vibration information, and an estimating means to estimate the load on the bearing based on the rotational speed and vibration value using a predefined table.

* The device measures vibrations and rotational speed of a rolling bearing during rotation.
* It calculates a vibration value for a predetermined frequency using the measured vibration information.
* It estimates the load acting on the bearing based on the rotational speed and vibration value using a predefined table.

Potential applications of this technology:
* Industrial machinery: This device can be used in various industrial machinery that relies on rolling bearings, such as motors, pumps, and turbines. It can help monitor the load on the bearings and detect any abnormal conditions or potential failures.
* Automotive industry: Rolling bearings are widely used in vehicles, and this device can be integrated into automotive systems to estimate the load on the bearings and ensure optimal performance and reliability.
* Aerospace industry: Rolling bearings are critical components in aircraft engines and other aerospace applications. This device can provide valuable information about the load on the bearings, helping to prevent failures and improve safety.

Problems solved by this technology:
* Accurate load estimation: By combining vibration and rotational speed measurements, this device provides a more accurate estimation of the load acting on the rolling bearing. This can help prevent overloading and optimize maintenance schedules.
* Early fault detection: Abnormal vibrations in rolling bearings can indicate potential faults or failures. This device allows for early detection of such issues, enabling timely maintenance or replacement before catastrophic failures occur.
* Improved reliability and lifespan: By monitoring the load on the bearings, this device helps ensure that they operate within their designed limits. This can extend the lifespan of the bearings and improve the overall reliability of the machinery or system.
