Spirals and Squares
When I hear the word jaw, numerous things come to mind. A few include the thriller shark movie, the jaws of life and mouths of people or animals. Then of course, there are jaw couplings. While these may not be the first thing to come to mind, for many of those in manufacturing and related industries, it may be. Types of shaft coupling, these products are used to provide mechanical power in the form of torque to pieces of rotary equipment. Jaw couplings are excellent shaft coupling solutions because of their resistance to oil, dirt, grease, sand and moisture. In addition, they do not require any lubrication making them even easier to use.
There are two main types of jaw couplings, square and spiral. Square jaw couplings are used in situations where the product does not need to be engaged and disengages in motion or under load. They are able to provide power when rotating in either direction. Meanwhile spirals jaws are able to shift fairly easily, they can be used to engage or disengage while in motion. However, this should still be done only at low speeds or with moderate loads. And while square jaw couplings can transfer power no matter what direction they are being used in, spiral jaw couplings can only transfer power in one direction.
Another nice benefit to spiral jaw couplings is that they can be designed to be either right or left handed. The only issue that jaw couplings can have is they lack misalignment capability. Yet, even with this one disadvantage, jaw couplings can be useful in countless situations. Especially useful in situations where moderate speeds and loads are being employed, these products can be the perfect solution for many manufacturers. This allows the mechanical power transfer smoothly and efficiently when needed.
