A locking device constitutes a crucial mechanical component designed to prevent coupled shafts and other machine elements from dislocating when subjected to external forces. These forces may include initial installation errors, temperature variations, vibrations, and more. The locking devices are paramount for the safety of an entire system and are commonly utilized in systems requiring the coupling of multiple components.
Applications of Locking Devices
Locking devices find extensive applications across diverse industries, including aerospace, mechanical, medical, and commercial sectors. Designers often work closely with shaft collars in these industries, creating myriad moving machinery applications. These devices are particularly prevalent in electric motor-driven designs, especially at the gearbox and electric motor assemblies.
Shaft collars fulfill three basic functions:
- Setting shaft position
- Spacing locking device components on shafts
- Limiting shaft movement
Role as a Mechanical Stop
Shaft collars often serve as mechanical stops on cylinders and actuators, location points for motors and gearboxes, and for maintaining the shafts connected with bearings and sprockets. Some variants of shaft collars are more suited for specific applications than others.
Setscrew shaft collars, for instance, are cost-effective and easy to assemble, making them a popular choice despite the advent of clamping collars. Setscrew shaft collars are particularly prevalent in applications that don’t require post-installation adjustments and where cost plays a significant role.
The Design and Functionality of Locking Device
A locking device is engineered to keep mated shafts and components from loosening out of place when subjected to a variety of operating conditions. They are often the linchpins of safety in multiple systems and are frequently used in systems that require coupling various components.
Frictional locking devices perform the same functions using the coefficient of friction between the two contacting surfaces. A classic example is when the locking device is inserted between the shaft and the hub of a system. The locking device then expands to fill the gap, holding the components in place through friction. This is usually a metallic or nonmetallic hollow cylinder, sometimes with a slit on one side. The nut is another common frictional locking device, working with a combination of friction on the shaft threads, slight stress on the bolt, and compression of the parts held together.
