Assembly of Mechanism without Keyways
Keyways (also known as keys) are an integral component of many types of mechanisms, from clocks to automobiles. They are a series of grooves or cuts which are made in a component that fit perfectly onto an adjacent component. This helps to keep the two components perfectly aligned and prevents them from moving out of place, as well as providing extra strength and support. Unfortunately, keyways also require additional work and cost to manufacture, so many people are looking for alternatives to traditional keyway assembly.
One such alternative is the assembly of mechanisms without the use of keyways. This technique eliminates the need for manufacturing grooves or cuts in components, reducing the cost of production and assembly time. Moreover, it provides a secure, stable connection between parts that is robust enough to withstand vibrations and shock.
This method of assembly without the use of keyways starts with three components, an inner part, an outer part, and a third piece referred to as a “saddle”. Firstly, the inner part is located in the outer part, and then the saddle is inserted in between them. This creates a meshing of the parts that prevents them from moving out of alignment.
Once the parts are meshed, a special locking compound is applied to the outside of the components to ensure that the parts stay in place. This locking compound is usually an epoxy or a two-part resin. It fills up the gaps between the parts and provides a strong seal that bonds the parts together.
When the compound has been applied and allowed to harden, the mechanism without the use of keyways is ready to use. This assembly technique is used in applications such as bearings, varying speed pulleys, and electric motors.
Using this method, the assembly time and cost is drastically reduced. In addition, the assembled parts are less likely to wear out or require replacing, as there are no grooves or cuts that can become worn or damaged. This increases the lifespan of the mechanisms and reduces the amount of maintenance required.
In conclusion, the assembly of mechanisms without the use of keyways has shown itself to be an efficient, cost-effective alternative to traditional assemblies. It eliminates the need for manufacturing grooves or cuts in components, reducing cost and assembly time, while providing a secure, stable connection between components that is strong enough to withstand vibrations and shock.
