A key is a mechanical part used to connect two rotating elements, such as a shaft and a pulley or gear, enabling the transmission of motion and force.
They come in a variety of forms, including half-moon, straight-end and 2 round-end keys.
They are essential in many industries to ensure a reliable and durable connection between mechanical components.
A disk key, often called a half-moon, also known as a Woodruff key, is a type of key with a round shape.
It is inserted into a disc-shaped keyway on the shaft and hub, ensuring a solid, reliable connection.
They are mainly used in applications requiring robust fastening, such as drive shafts and heavy industrial machinery. They are common in environments where high torque forces are present.
The nfe 22179 standard specifies the dimensions and tolerances of half-moon keys used in mechanical assemblies. This standard ensures compatibility and interchangeability of keys in industrial systems.
Standards, such as nfe 22179, are essential to ensure that mechanical components are manufactured to precise specifications, ensuring their reliability and efficiency in a variety of applications.
Shapes and dimensions
They can be round or semicircular. Dimensions vary according to industry standard specifications and application requirements.
Materials used
Disc keys are generally made from carbon steel, stainless steel or aluminum alloys. The choice of material depends on wear and corrosion resistance requirements.
Application comparison
They are used for robust fastening in high-load applications and in precise alignments with easy installation.
Industrial sectors
These keys are used in a wide range of industrial sectors, including automotive, aerospace, machine building and energy. Their versatility makes them suitable for a wide range of mechanical applications.
Machine types
They are found in electric motors, compressors, transmission equipment, and various other types of industrial machinery. They are essential for ensuring a solid, reliable connection.
Durability
Thanks to their robust design and the high-quality materials used, disc keys offer great durability and increased resistance to wear and corrosion.
Efficiency
They ensure efficient torque transmission and reliable fastening, even under difficult operating conditions. Easy installation and minimal maintenance make them popular choices in the industry.
