subject: Know What To Expect From High Quality Keyed Shafts [print this page] A keyed shaft is a regular shaft that has a key way running through its entire length. Conventionally, engineers would purchase plain shafts and then key them at the machining shop. However, this would not only consume a lot of time, but also add to the overall process costs. Hence, a number of firms today provide ready shafts in different dimensions that have a pre-machined key way. This results in significant time savings and the shaft that has been fully keyed can be instantaneously put to use. These components are available for use with OEM parts or they can be used as replacement parts in various machines and mechanisms.
In this article, we shall discuss some of the hallmarks of keyed shafts that you can expect from a reputable manufacturer:
First of all, it is advisable to make use of shafts that are 1045 grade and are turned, ground and polished.
By choosing this particular grade, you can be sure about using the best quality component that offers you high strength and accuracy.
Another important factor that you need to consider is the concentric accuracy of this component as well as its straightness.
While certain applications would require a highly perfect surface, some other operations can accommodate the use of a regular surface.
Your chosen manufacturer should be able to offer you a wide selection of standard as well as custom shafts that are pre-keyed.
When you choose the highest quality, you neednt worry about constant replacements or damages. This would not only protect your investment, but also translate into low downtime. Also, low quality shafts would not be able to bear the constant vibrations and wear and tear that is commonplace in a machine. On the other hand, a high grade shaft can be easily fitted into a standard bearing. More importantly, they will offer you a vibration-free operation even at high speeds. If you need to use these components in an environment that is highly susceptible to corrosion, you could discuss your specific requirements with your chosen manufacturer.
And, if your concern relates to high grade mechanical properties in your keyed shaft, then you should opt for medium carbon steel. Low carbon steel is better suited to combat corrosion, but might not always give you the tensile strength that you want. In addition, there are several operations where keyed shafts might be exposed to very high or very low temperatures. If your operation is one of these, then you should take the professional opinion of the keyed shafts manufacturer before making a final decision.
There are hundreds of commonly seen applications of keyed shafts. You shall find them being used in conveyor belt systems, power transmission operations, speed controllers, engines, and automobile mechanisms among several other applications.
