FLEXURE FACTS

Solved Application Story # 38

OFFICE EQUIPMENT

THE CHALLENGE

 Here is an example of a customer who was already using Helical's flexible coupling. They were entering into the design stage of a new product and wanted to use a standard MCAC150. It met all of the primary requirements of the new product but it needed to be shorter. They later found, when disassembling the machine for maintenance purposes, one end was required to have a removable cap. To be assured that a positive drive was maintained, they asked that a double "D" bore be incorporated. This was a case where the customer wanted it a standard "except for...."

There was a second coupling used in another location. It was a standard coupling but also required a double "D" in place of the normal round quarter inch bore. Another "except for...."

THE SOLUTION

As a change request was made, Helical's Application Engineer was able to meet the requirements. Each time there was a change, a sample coupling was sent for the customer to test and evaluate in the actual application. Being able to meet the specifications in a timely manner allowed Helical to supply the customer these couplings for several years. There were 5 couplings of the smaller size and 1 of the larger size per machine.
