Setting Up a Motor-Gearbox for Vibration Measurement

Gearboxes are common in industry.  They are used to increase or decrease speed from the driver, provide increased torque, and change direction of power transmission.   There are two main types of commonly-used gearboxes:   GEARBOX TYPE Parallel or Standard Gearbox-one where the input and output shafts are parallel. Bevel or Right Angle Gearbox-one where…

Calculating Output Speed Using Pulley Diameters and Input Speed

Knowing the correct shaft speed of both shafts on a belt-driven machine is important when performing machinery diagnostics. Ideally you would do this by first identifying the input and output speeds using a strobe light, photo tach or laser tach. Once you know the accurate speed of both components, use this formula to determine the…
