What is a Bevel Gear?

A Bevel Gear (GEAR,BEVEL) is a gear in the form of a frustum of a cone, with straight, skewed, or curved teeth, cut on the external face. See also GEAR, ANTIBACKLASH, BEVEL.

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:

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.

What is a Worm Wheel Gear?

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 Matched Bevel Gear Set?

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

What is a Spur Antibacklash Gear?

A Spur Antibacklash Gear (GEAR,ANTIBACKLASH,SPUR) is an item having one fixed gear and one free gear, both having the same complement of spur gear teeth, mounted on a common hub. The free gear is attached to the fixed gear by springs and operates as one gear. Upon installation with the mating gear, the teeth of the free moving gear are preset to mesh with teeth other than those of the fixed gear. This spring tension between the fixed gear and the free gear eliminates any free motion between the driver and the driven gear. The gear is used where identical and accurate transmitted motion between gears is required.

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 Drive Motion Gear?

A Drive Motion Gear (GEAR,DRIVE MOTION) is a gear, cylindrical or conical in form, with teeth on the outer surface used for the accurate transmission of motion.

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.
