Gears are components that are applied in numerous industries, especially in automotive, aerospace, and industrial machinery. This article provides an extensive guide on gear functions, principles, manufacturing, types, classification, teeth profiles, nomenclature, and the essential calculations involved in gear design and analysis. What Are the Functions of Gears? Gears are mechanical components that serve several critical functions in transmitting and controlling rotational motion. They adjust rotational speed by meshing gears of different sizes, either increasing or decreasing it based......

Welding is a fabrication technique that joins materials and creates strong, permanent bonds. However, the complexity of welding leads to the potential for defects and imperfections that can compromise the quality and safety of welded joints. This guide introduces the most common types of welding defects with definitions, diagrams, detection methods, causes, preventive measures, and effective remedies. What Are Weld Defects? Weld defects, which are irregularities that occur during the welding process, can stem from inappropriate techniques, unsuitable materials, poor workmanship, and a la......

Fasteners refer to components that serve the function of securing objects together. Threaded fasteners, which contain threads and are manufactured to precise dimensions, exert their fundamental function through the interaction between external and internal threads. This capability allows threaded fasteners to play a significant role in the connection and fastening of objects, as well as in facilitating movement.  I. What are Threaded Fasteners? Fasteners are universal components used for mechanical connection, fixation, or sealing. They securely join two or more parts ......

Whether you’re an engineer, technician, or someone involved in industrial operations, knowing what a blind flange is and how it works can make a significant difference in your projects. We’ll explore the definition, types, applications, and dimensions of blind flanges, ensuring you have all the necessary knowledge to select and use them effectively in your piping systems. What Is a Blind Flange? Blind flanges are crucial components in piping systems designed to block off sections of pipelines or vessel openings. They are essentially solid discs used to cover or close the end ......

Set screws are widely used in mechanical assemblies to secure components such as gears, pulleys, and collars onto shafts. Unlike standard screws, they do not have a protruding head, allowing them to be used in confined spaces. The purpose of this guide is to provide detailed information on set screw types, size charts, and torque specifications. What is Set Screw? A set screw is a fully threaded fastener without a head, designed to secure one object within or against another. It is tightened using an internal drive such as a hex socket (Allen), slotted, or Torx. The tip of the......

Jam nuts are an important component in mechanical fastening, providing a secure way to prevent loosening in applications where vibration or movement occurs. This article provides a detailed look at jam nuts, including their purpose, sizes, torque specifications, and how they compare to other types of nuts. What is a Jam Nut? A jam nut, also known as a thin nut, is a type of fastener that is about half the height of a standard finish nut. While the circumference and thread sizes are the same as a standard nut, its reduced height makes it suitable for applications where spac......

Gear couplings are essential components in many industrial applications, which sizes are available, and how to select them? This article will talk about what gear couplings are, how they work, manufactured, their dimensions, and their differences from other types of couplings. Additionally, we will provide full and half gear coupling size charts to aid in selection and application. What Is Gear Coupling? A coupling in mechanical connection refers to a machinery device that connects two shafts together. The gear coupling is one of the types of couplings, used for the transmission of torqu......

Angle is one of the major shapes of structural steel, with a unique shape, mechanical properties, and specific ways to measure it. Today, we’ll break down the steel angle types, properties (strength), grades, measurement, and cutting, as well as the angle iron size chart in mm and inches (PDF provided). What Is Steel Angle? Steel angle, also known as angle iron or steel angle bar, is a type of structural steel shape that is commonly used in construction and manufacturing. Steel angles have an L-shaped cross-section, which consists of two legs that meet at a 90-degree angle. These ......
