Greatly increased torque Disk Couplings Echt-Flex NER Series
No need to assemble the disk, no need to replace the disk in the center unit during maintenance
Echt-Flex Coupling NER series does not require to assemble the disk in the center unit to the customer's equipment nor replace/disassemble the disk in the center unit during maintenance.
Reasons for not needing disk replacement-1: Torque transmission mechanism
Transmission of torque by frictional force
Axial force is generated on the bolt by tightening the U-nut, and torque is transmitted by the frictional force between the hub, washer and disk.
Since there is no sliding part, it is not necessary to replace the disk during maintenance.
Reasons for not needing disk replacement-2: Tsubaki's original center unit structure
In the conventional disc coupling, the disk part had to be assembled by the user, but NER series has a center unit structure, and the disk is shipped from the factory as assembled with the spacer and flange. Even during maintenance, the disk can be attached and detached without disassembling, and there is no need to replace the disk.
Benefits
- ・No need to assemble disks on site.
- ・Can be tightened with a small torque wrench.
- ・Extra man-hours can be reduced by eliminating incorrect washer insertion and loss of parts.
- ・Hub A can have larger shaft bore diameter.
- ・Detachable without disassembling the disk during maintenance.
【Example of customer's consideration 】
Disk coupling is friction transmission and has no sliding parts and can be used for a long time.
In addition, NER Series has a center unit structure, eliminating the need to assemble and disassemble the disk section.
It is usually not necessary to have a disk ready for maintenance.
We'll be checking the pump next month, so we have to prepare a coupling disk.
There is no need to prepare the disk because the disk does not wear and does not need to be disassembled!
Certainly, with this coupling, we don't have to replace the disk!
