Remote Monitoring of Bearings
Mechanical failures caused by bearing damage can lead to huge losses. To better monitor the status of bearings and conduct preventive maintenance, InHand Networks delivers a solution featuring the IG902 edge computing gateway, helping acquire real-time data of the bearing status, upload data to the cloud for analysis and maintenance.
Background
As important basic rotating machinery parts, bearings are widely used in a variety of industrial fields. According to statistics, about 30% of mechanical failures worldwide are caused by the damage of bearings every year, so its running state has a huge impact on the normal operation of equipment.
During machinery operation, a lack of oil, collision, friction and other factors may lead to an increase in bearing temperature, causing “burning shaft” phenomenon. Fatigue wear, indentation, cracks, surface peeling, adhesive and impurities can incur abnormal vibration and damage of bearings; in worse cases, the anchor bolt may vibrate or break, with bearing burned out and bearing bush flying out. Therefore, it is necessary to monitor the running state of bearings in order to avoid sudden failures.
Customer Requirements
Extensive Interfaces for Connection to Multiple Devices
A variety of data-collecting devices require different interfaces including Ethernet ports, RS232 and RS485, etc.
Stable Cellular Network Access for Data Transmission
Onsite bearings should be constantly monitored so that faults can be prevented to avoid downtime and losses.
Support for Major Industrial Protocols and IoT Clouds
Data are collected through Modbus, OPC and other major industrial protocols. The solution is expected to read and analyze data, process data and then send them to the cloud.
Solution
InHand Networks offers a remote monitoring solution for bearings featuring its InGateway902 industrial edge computing gateway, helping collect data of the bearing status (vibration, lubrication, temperature, abrasion, etc.) and upload them to the cloud for analysis and preventive maintenance.
The solution consists of the bearings, sensors installed on bearings (such as vibration sensor, temperature sensor, lubrication sensor, etc.), the IG902, the Device Manager and a third-party cloud. Data collected by those sensors are transmitted to the IG902, where the protocols of the sensors are analyzed. The IG902 then sends the data to the cloud in a standard format. In the cloud, data are stored and analyzed, so that the operation status of the bearings can be evaluated, and maintenance staff are advised what to do with those bearings.
Benefits
Fast, Secure and Reliable Connectivity
Available with LTE CAT4/CAT1 cellular networks, Wi-Fi and wired connection, multiple link redundancy technologies and security strategies, the IG902 provides fast, secure and uninterrupted network access, ensuring that devices are constantly connected.
