Shaft locking device

A shaft to hub lock is critical in the design of a mechanical transmission as an unsuitable choice could cause serious damage to the machine or system and result in economic loss. ‍ Shaft-hub coupling designs must take several parameters into account: ‍ » Assessing application loads: torque, bending moment, axial force, radial force. Stresses that may occur simultaneously. » Alternating loads, sudden starts and stops, very rapid acceleration. » Fatigue limits of the coupling components. » Suitable material use. » Frequent installation and removal requirements. » Fretting corrosion. Traditional shaft-hub locking systems include: ‍ » Feather keys. » Key. » Spline coupling. » Interference coupling: forced. Simply by tightening the screws, SIT-LOCK® keyless locking devices create an axial force on the shaft and the hub that is spread over the entire contact surface. Unlike traditional systems. They offer numerous advantages.
