Gearbox: Selection Criteria, Types of Bearings, Lubrication and Performance Monitoring

There are many factors to consider in the selection process of the proper gear speed reducer. Unfortunately, it is not as simple as calculating speed, torque, horsepower, and output RPM. With the introduction of computerized engineering manuals, most gear reducer manufacturers have made it easy to make basic gearbox selections. The basic selection process is […]

Gearboxes: Detailed Explanation, Terminology and Selection Process

What is a Gearbox? A box or case containing gear sets has many different names: speed reducers, reduction gearboxes, gear speed reducers, and gearboxes. Gearboxes are devices for the transmission of movement (precisely torque and speed) between two shafts, those shafts can have axis parallel, perpendicular, or cross to each other. In industry, gearboxes are

Column Buckling

What is Buckling ? Columns are an important part of machines or even civil structures such as bridges. To differentiate column and Beam, Take the example of the most common case of horizontal beams subjected to load perpendicular to its length (such as simply supported beam or cantilever beam). Those beams undergo bending or flexural
