Journal Bearing Vibration Sensor

Relying on a pair of orthogonally installed proximity sensors the orbit of the shaft.

Journal bearing vibration sensor.

Lated measurements eddy current probe systems are the best solution for shaft posi tion measurements in sleeve bearing equip ment the selection and speciications of skf s range of eddy current probes is. Journal bearing description most rotor support bearings are either. The last type of vibration sensor we will discuss is an eddy current or capacitive displacement sensor. Vibration sensor selection 3.

These sensors operate with magnetic fields. Machines utilizing sleeve journal bearings they have excellent frequency response with. Eddy current sensors are non contact devices that measure the position and or change of position of a conductive component. Individual sensor cables into a large multi conductor cable typical multi conductor cable plain bearings some fans and motors are equipped with plain bearings.

Physical characteristics such as temperature rating size and connector orientation are also considerations. So you d rather focus on the force in vibration rather than the displacement which means you shall use an accelerometer. The sensor has a probe which creates an alternating current at the tip of. Paper will present an introduction to journal bearings and lubrication.

There are no rolling elements in a plain bearing and typically the shaft is supported by a film or wedge of oil. Often need to use both sensor types. Lubrication technology goes hand in hand with understanding journal bearings and is integral to bearing design and application. If your machine has anti friction bearings rolling element bearings the expected vibrations are usually very small in displacement amplitude to be discovered clearly with a proximity probe.

These bearings are often referred to as sleeve bearings or journal bearings. Based on the mathematical model of a symmetric rotor supported by one rigid journal bearing and one oil film journal bearing muszynska 1 2 mathematically interpreted the dynamic phenomena related to synchronous vibration and self excited vibration. Vibration detection on sleeve bearing equipment. Since they have significant damping fluid film journal bearings have a strong impact on the vibration characteristics of machinery.

Wirelessly access stored data through any smart phone or tablet during routine inspections. Aside from typical mechanical issues such as misaligned couplings and unbalance the vibration analyst can also detect electrical issues that cause mechanical vibrations. Typical applications demand vibration measurements in the horizontal vertical and axial direction on both the inboard and outboard motor bearings.
