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

Use the below calculation program to calculate the second moment of area about the x-axis and y-axis, the second Polar moment of area about the z-axis, and the Radius of gyration about the x-axis and y-axis. Take care of the units of measurement such as mm or inch while entering the inputs. You can calculate
Mechanical power is transmitted through the reciprocating and rotating parts such as shaft, gear, sprocket, couplings, motor, etc. whereas the fluid power is transmitted by the pressurized fluid which can be the air, gas, or oil. In general, systems with air as a medium are known as Pneumatic system,s and with oil are known as

Whenever a machine component such as a shaft or structure is under loaded condition a complex stress is generated in its material. The machine Designer has to take care of the weakest part or portion, the maximum possible stress condition, or other practical factors for the component to survive under load conditions. It is critical

Mechanical power press works on the principle of slider crank mechanism or modified mechanisms such as Kuncle joint or linkage drive. The tonnage of the press (pressing force) is required before the slide reaches the bottom dead center (BDC). The reason is that the metal sheet has some thickness and forming force should be transferred

Introduction The power generation industry can be regarded as the cornerstone of modern civilization. Modern power generation takes a variety of forms as will be seen in the below article. It will be evident that the magnitude of this industry is such that one article cannot cover all of its details. The top 10 electricity
Introduction Power Screws are one of the common machine elements used in various applications that require converting the rotating motion (Torque input) into a linear motion (Force output). The best example of a power screw is the Lifting Jack used for changing the car wheel. Power Screws are also called lead screws and are used
