It has been a challenge to reduce unwanted vibration in rotating equipment. The impact of this vibration can range from premature failure of the machine to consumer’s perception of poor product quality. Many designers and product engineers from all industries have been working diligently to
Numerous companies specialize in supplying measurement and data acquisition systems. Equipment is available at various price points and with different capabilities. Selecting the appropriate equipment can save you time and money if done correctly. Before purchasing any equipment, it is important to identify your particular
Rolling element bearings have been widely used in rotating equipment. They are designed to carry load and provide constrained motion between two or more parts. A rolling element bearing consists of outer race, rolling elements (balls, cylindrical roller, etc), inner race, and a cage to
Any mechanical looseness in a rotating machine will typically generate a peak in the spectral data at the 1X speed (synchronous speed). There are a few types of looseness that may occur: 1. Rotating looseness 2. Structural looseness Rotating Looseness This form of mechanical looseness is
The main functions of a rolling bearing are to carry load and provide near frictionless environment to support and guide a rotating shaft. Rolling bearings have four components: outer race, rolling elements, inner race, and a cage to support and guide the rolling elements. The
A gear consists of a rotating part with teeth or cogs that are used to mesh with other gears in order to transmit torque. Gears are useful for changing the speed, torque and direction of the source of power. Most gears rotate, however linear motion
