Oil Bath / Spalsh Oil Lubrication Decisions in connection with the selection of lubricants must parallel decisions in connection with the supply of the lubricant to the bearing for maintaining conditions that will prevent rapid deterioration of the lubricant and bearing. An oil sump applicable to horizontal, inclined, and vertical axis arrangements provides a small […]

What is Unbalance? According to the International Organization for Standardization (ISO) unbalance or imbalance is defined as “that condition which exists in a rotor when a vibratory force or motion is imparted to its bearings as a result of centrifugal force.” The effect occurs when a rotor’s mass is unevenly distributed about the axis of

What is Grease? Grease composition can be assumed like a sponge with fluid absorbed inside. In place of a sponge, the thickener is there that holds the base oil and additives. The base oil and additives are the major components in grease formulations and have a considerable influence on the performance of the grease in

Importance of Gearbox in a Machine Gearboxes are devices for the transmission or translation of movement. In industry, gearboxes are used to transform the speeds and torques produced by the prime mover in order that they are appropriate to the machine which is to be driven. The speeds and torques required by the machine are

What is Hertzian Stress? The area of contact, when two curved surfaces are in contact, is theoretically zero, so this will cause infinite stress and immediate failure of the object. However, on the application of load, a real area of contact is formed due to the deformation of the mating surfaces. Thus, when two bodies

Rolling element bearing, also known as a rolling bearing or simply bearing is a part of rotating machinery that carries a load by placing rolling elements (such as balls or rollers) between two bearing rings. Bearing performs three functions – Support the shaft, Carry the load from the shaft, and reduce friction. The importance of rolling-element bearing
