What is the role of track shoulders in fasteners?

The track shoulder plays an important role in fasteners. It can limit axial movement, bear axial load, increase axial stiffness and improve the self-locking properties of fasteners. Below we will introduce in detail the role of rail shoulders in fasteners:
Limiting axial movement: The track shoulder generates friction through the contact surface with the shaft shoulder. This friction can hinder axial movement, thus limiting axial movement. This limitation is important to maintain the stability and accuracy of mechanical systems.
Bearing axial loads: The track shoulders are structurally designed to withstand axial loads. In fasteners, axial load is usually caused by the weight of the connected parts, external force or torque, etc. The track shoulder supports these axial loads through its structural strength and friction, ensuring that the fastener remains stable when loaded.
Increase axial stiffness: The design and processing quality of the track shoulder have a positive effect on improving the axial stiffness of the fastener. Axial stiffness refers to the ability of a fastener to deform in the axial direction. The thickness, width and material strength of the track shoulder will all affect its axial stiffness. Through reasonable structure and processing methods, the track shoulder can provide sufficient axial stiffness to ensure that the fastener remains stable during use.
Improve the self-locking performance of fasteners: The design of track shoulders can also improve the self-locking performance of fasteners. Self-locking refers to the ability of a fastener to remain stable in a pre-tightened state and prevent loosening and falling off. The track shoulder achieves self-locking through the friction generated by its contact surface with the shaft shoulder. This friction can provide a reverse force to keep the fastener in a pre-tightened state, ensuring the reliability and stability of the connection.
In short, the role of track shoulders in fasteners is multi-faceted. It can limit axial movement, bear axial load, increase axial stiffness and improve the self-locking properties of fasteners. These effects are very important to maintain the stability and accuracy of mechanical systems, so track shoulders are of great significance in the design and manufacture of fasteners.
