A key is a mechanical part used to connect two rotating elements, such as a shaft and a pulley or a gear, thus allowing the transmission of movement and force.
It comes in various forms, such as Half moon key, the Straight end key or even the 2-round end key.
They are essential in many industries to ensure a reliable and durable connection between mechanical components.
A disc key, often called a half-moon key, also known as a Woodruff key, is a type of key that has a round shape.
It is inserted into a disc-shaped groove on the shaft and hub, ensuring a solid and reliable connection.
They are mainly used in applications that require a sturdy attachment, such as drive shafts and heavy industrial machines. 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 the compatibility and the interchangeability of keys in industrial systems.
Standards, like NFE 22179, are critical in ensuring that mechanical components are manufactured to precise specifications, ensuring their reliability and effectiveness in a variety of applications.
Shapes and dimensions
They have a round, semicircular shape. Dimensions vary according to industrial standard specifications and application requirements.
Materials used
Disc keys are generally made of carbon steel, stainless steel, or aluminum alloys. The choice of material depends on the needs in terms of resistance to wear and corrosion.
Comparison of applications
They are used for sturdy fasteners in high-load applications and in precise alignments with easy installation.
Industrial sectors
These keys are used in various industrial sectors, such as automotive, aeronautics, machine manufacturing, and energy. Their versatility makes them suitable for numerous mechanical applications.
Types of machines
