The rolling element bearing is a standard element for the construction ofmachinery and equipment. The correct function of this force-transmitting and moving component is critical for uptime of machinery and equipment. Due to the high dynamic and static loads during operation as well as design limitations the rolling element bearing is often the Achilles' heel with regard to lifetime. Thus unforeseen damage to the bearing often leads to produc- tion or quality loss. State-of-the-art for industrial monitoring of rolling ele- ment bearings is presently restricted to the intermittent measurement with handheld measuring instruments and to expensive central measuring systems which due to their enormous acquisition costs only make sense economically for monitoring expensive machines like turbines or large gears.

Parameter setting software for rolling element bearing monitor VBS001

Easy parameter setting

Expert software for vibration diagnostic unit VES001

For the easy parameter setting of the rolling element bearing monitor, it isonly necessary to take the relevant bearing data from the rolling element bearing database. For variable speed drives information on speed must be provided. The speed can either be provided by an analogue signal or a pulse generator connected to the sensor. The mechanical dimensions are 36 x 36 x 36 mm.

With the efector octavis ifm brings the first vibration sensor with integratedrolling element bearing diagnosis based on frequency analysis on the mar- ket. Due to the implementation of a proprietary diagnostic algorithm several different rolling element bearings can be monitored separately and their condition can be displayed via a “green-yellow-red” logic. Monitoring and diagnosis are performed in real time. Thus vibration measurement technolo- gy is integrated into automation technology so that expensive expert know- how for a reliable bearing diagnosis is not required. Therefore permanent monitoring of small machines and components is possible for the first time without losing the diagnostic quality of expensive systems.
