  • Ways To Ensure Better Maintenance Of Electric Motors

    but, if not detected on time, vibration can reduce the life span of an electric motor, which then eventually leads to motor bearing failure or failure of windings. In most cases, the cause of vibration is mechanical in nature, such as a faulty sleeve or ball bearings, too much belt tension, or bearing distributors account representatives are trained in performing root cause analysis to identify solutions for preventing premature bearing failures. portion of this analysis is a review of annual or semi-annual detailed purchase history that should bring up any abnormally high usage items and commit to assisting in reducing consumption.

  • High Speed Spindle Design And Construction Modern

    the most common cause of bearing failure is fatigue, which causes the races to become rough, leading to heating, and eventual mechanical failure. bearing life, in general is affected by the following parameters: bearing loads, axial and radial vibration levels quality and quantity of lubrication maximum speed average bearing temperaturewhen the bearing is subjected to vibration, it causes the oil in the grease to separate from the thickener, allowing it to drain away from where it is needed much faster. therefore, these two correcting factors position and vibration should be taken into consideration. the final correcting factor is that of the bearing element shape.

  • How To Inspect A Gearbox Machinery Lubrication

    It is important to inspect gear tooth contact patterns because they can disclose gear mesh misalignment. the inspection should be done during commissioning of the gearbox to catch misalignment before it causes damage. inspections should be regularly repeated to determine any changes in contact patterns caused by problems such as bearing failure.the top bearing killers, or causes of damage and premature end of bearing life, are inadequate lubrication, contamination, overload, and improper handling and installation.
