Selecting the right coupling bolt requires careful examination and asking the right questions. It may be challenging to find the “perfect fit,” but by keeping these tips we have compiled in mind before visiting an auto parts manufacturer in Australia, you can soon get your hands on the solutions you need.
Without further ado, here are some tips for choosing the right coupling for your application.
What should the Coupling do?
The first question you should ask yourself before purchasing new couplings should be related to the capabilities and what you expect these components to do. Are the application speed and torque high or low? Is it backlash free? How much maintenance does it need? Does the coupling need to absorb shock? What about the cost?
Never Select Couplings Based only on Habit
Often, engineers purchase couplings for their next project based on their previous one. It can be a habit for most, but not all couplings are made the same. It is best always to identify the parameters and capabilities rather than just by familiarity.
Mounting Method
One way to determine the success of your coupling is to figure out its mounting method. Keyless locking devices are preferred for shock applications and reversing loads because they are backlash-free, while taper bushings and traditional keys are best for applications with minimal shock.
The Environment
You also need to consider if your coupling will operate in a corrosive or harsh atmosphere since the material required will vary depending on the type of environment. You should also keep in mind the temperature to which the coupling will be exposed. Materials may go from stainless steel and titanium for less harsh environments to Inconel for higher temperatures.
Choose the Correct Type and Size
A common mistake when specifying a coupling is choosing the wrong size and type. With many choices in the market, it is easy to mismatch the necessary application requirements. Before you select a coupling, always understand the application requirements and functional advantages.
Performance Ratings
Remember, each manufacturer will have different performance ratings for their products since there is no singular governing body for all couplings and how their performance is rated. Torque ratings may be from calculations or the manufacturer’s tests, so always examine their data and footnotes.
Purchase Coupling from one of Australia’s Top Manufacturers
Another aspect you need to consider when choosing couplings is the quality. Only the best manufacturers can provide you with components made of durable and efficient materials to suit your every need.
Poly Flex offers flexible disc transmission coupling designed to cover many gearboxes. Though their couplings are made for marine use, they can also be utilised for many industrial driveline applications. Check out our website to learn more.
