What is a Helical Gear?

A Helical Gear (GEAR,HELICAL) is a gear, cylindrical in form, with teeth on the outer surface at an angle to the axis of the gear. See also GEAR, ANTIBACKLASH, HELICAL:

What is an Internal Gear?

An Internal Gear (GEAR,INTERNAL) is a gear with teeth formed on the inner surface of a cylinder or cone.

A Spur Gear (GEAR,SPUR) is a gear, cylindrical in form, with straight teeth on the outer surface parallel to the axis of the gear. See also GEAR, ANTIBACKLASH, SPUR. For bulk material, see ROD, PINION.

A Worm Gear (GEAR,WORM) is a gear with teeth on its outer surface in the form of helical threads.

What is a Groove Pulley?

A Groove Pulley (PULLEY,GROOVE) is a pulley with one or more grooved faces or rims of the same diameter. For pulleys encased in a shell or frame, see BLOCK, TACKLE.For items specifically designed for aviation, see PULLEY(1), GROOVE, AVIATION.

What is a Cone Pulley?

A Cone Pulley (PULLEY,CONE) is a pulley having two or more adjoining grooved, flat or crowned faces in steps of different diameters or one having a single tapered face. For pulleys encased in a shell or frame, see BLOCK, TACKLE.

What is a Flat Pulley?

A Flat Pulley (PULLEY,FLAT) is a pulley with a straight or crowned face. The item may include belt aligning flange(s). Excludes PULLEY, CONE. For pulleys encased in a shell or frame, see BLOCK, TACKLE.

What is an Engine Starter Rope Pulley?

An Engine Starter Rope Pulley (PULLEY,ENGINE STARTER ROPE) is a grooved or flat faced pulley having one or more notches in the rim or flange for attaching a rope or cable for the purpose of cranking an engine.

What is a Matched Spur Gear Set?

A Matched Spur Gear Set (GEAR SET,SPUR,MATCHED) is a grouping of two or more or any combination of GEAR, SPUR; GEARSHAFT, SPUR and/or GEAR CLUSTER, SPUR which have been matched together for a given characteristic within a specified tolerance. Includes only those gears designed and tested to accomplish a specifically designed function.

What is a Gear Cluster?

A Gear Cluster is a cylindrical item having a full 360 degree (6.282 radians) complement of teeth on two or more surfaces. It may be a one-piece casting or composed of two or more separate items firmly held together by welding, rivets, pins, or the like, to form a single unit. It is designed to mount on a shaft. For items consisting of a shaft with an integral complement(s) or gear teeth, see GEARSHAFT (as modified). Excludes GEAR SUBASSEMBLY, SPEED DECREASER.

What is a Cable Chain?

A Cable Chain (CHAIN,CABLE) is a flexible mechanical device consisting of one or more rows of cast or stamped links without side plates or rollers. The links may be replacable by splicing. Excludes metallic chains and belts.

What is a Timing Belt Pulley?

A Timing Belt Pulley (PULLEY,TIMING BELT) is a pulley with regularly spaced grooves parallel to the pulley axis on the face. It is designed to be used for timing purposes such as to synchronize the igintion spark with the completion of the compression stroke of the piston.

What is a Mechanical Drive Guard?

A Mechanical Drive Guard (GUARD,MECHANICAL DRIVE) is a safety device fabricated of rigid or semirigid material formed in various shapes. It may be fabricated from a single piece of material, and contains brackets, holes, or other means of attachments. It is designed to partially or fully inclose gear(s), pulley(s), sprocket(s), and the like.

NATO Supply Class 3020 is a classification within NATO Supply Group 30, which is dedicated to Mechanical Power Transmission Equipment.

NATO Supply Class 3020 specifically focuses on Gears, Pulleys, Sprockets, and Transmission Chain. These components play a crucial role in the mechanical power transmission process, enabling the transfer of power from one component to another within a system.

Gears are rotating mechanical devices with teeth that mesh with other gears to transmit power and motion. They are commonly used in various applications, such as automobiles, machinery, and industrial equipment.

Pulleys are wheel-like devices with a grooved rim designed to support and guide belts or ropes. They are used to transmit power and change the direction of force in systems like conveyor belts, elevators, and engines.

Sprockets are toothed wheels that engage with a chain or belt to transmit power and motion. They are commonly found in bicycles, motorcycles, and industrial machinery.

Transmission chains are flexible, linked chains that transmit power between two or more sprockets. They are commonly used in motorcycles, bicycles, and industrial machinery.

In summary, NATO Supply Class 3020 encompasses gears, pulleys, sprockets, and transmission chains, which are essential components in mechanical power transmission systems.
