When it comes to any vehicle including an aircraft, securing hardware is a primary task that needs to be done for safety. Loose hardware wiring can be a cause of tragic accidents and threaten many lives. As a result, it is crucial to secure the aircraft’s bolts and fasteners with safety wires to prevent accidents. Furthermore, one should always check such assemblies often to confirm whether they are tight and ready before take-off.
Roller bearings are mechanical components that support connecting and rotating shafts to help with movement and mobilization within machinery. Essentially, thesy are metal elements utilized to reduce friction and are equipped to handle radial, axial, and thrust loads. Moreover, they are found in a wide range of applications from the motor industry to home appliances, making them incredibly versatile devices. As such, there are different types of roller bearings available on the market, some of which we will outline in this blog.
Bearings of any type are not ever-lasting components. Over time, they experience wear, corrosion, and other forms of degradation depending on the applications in which they are installed. However, it is not common for them to fail without reason. Consisting of a donut-shaped piece of material, bearings are intended to restrict or limit the motion of a machine’s moving parts while simultaneously reducing friction between such parts.
In the world of fasteners, nuts are one of the most common types of hardware used for assembly. Typically, nuts are paired with a correlating screw or bolt, twisting onto the tail-end of the component to hold two or more objects together with compression. Depending on the application in question and the types of materials being used, there are a number of nut types that one may take advantage of. One notable option is the wing nut fastener, that of which is distinguishable by its large metal wings that extend outward from the circular component. Wing nuts are popularly used in applications where tightening and removal are done by hand, and they are used in projects small and large. To help you determine whether the wing nut is the right type of fastener for you, we will discuss its characteristics in more detail!
Propeller blades are similar to aircraft wings, with cambered and flat sides, chord lines that run throughout the blade length, and leading & trailing edges. Aircraft propulsion generated by rotating propellers requires the use of a highly complicated mechanism since the propeller takes on the features of a rotating wing. There are differential aerodynamic properties between the top and bottom of the propeller blades. Propeller blades tend to be long and thin, and because of their rotation, the speed of the blade tips tends to be faster than that of the near-hub sections. Consequently, analyzing the differential airflow generated around the rotating blades becomes difficult. This blog aims to deconstruct the complex working mechanism of propeller propulsion into a more simplified explanation for ease of understanding.
A fastener is a device used to mechanically connect two objects. Examples include screws, nails, nuts, bolts, washers, anchors, and rivets. They are not permanent in that they can be unscrewed, loosened, and taken apart. The advantage of fastening two objects together rather than welding them is that the separate components can be replaced and maintained more easily. Different fasteners provide different amounts of strength, but there is also more to consider when purchasing fasteners for varying applications.
A shaft bearing is a common mechanical component, often placed within assemblies to bear applied loads while facilitating the rotational or sliding movement between parts. With their general, yet important, role, shaft bearings commonly find use in a wide variety of applications ranging from industrial machinery to aerospace vehicles. To accommodate a diverse set of industries and needs, shaft bearings come in various types and designs, each varying in its qualities and characteristics.
In general, bearings are specialized components that assist an object’s rotation. Typically supporting the shaft that rotates inside machinery, bearings are found in automobiles, aircraft, electric generators, and more. As they find countless uses, bearings are available in varying types, one of which is called a rolling bearing.
