Introducing the EDC Elastomer Drive Shaft Coupling

The EDC is designed, machined, and assembled to order in Mt. Prospect, IL.  CAD models are online and easily configurable for download in minutes.  The EDC is available in four sizes based on the torque rating: 25Nm, 35Nm, 80Nm, and 110Nm. Derived from the design of GAM's EKC elastomer coupling, the EDC is a quality drive shaft solution at an economical price for this torque segment.

Split Hub Design

The EDC has a split hub construction for easy installation.  This design feature allows the coupling to be installed by placing it directly over the shafts that need to be connected.  The shafts can remain fixed and do not need to be retracted during installation to get proper shaft engagement.

GAM's Drive Shaft Lineup

The EDC is the latest addition to GAM's family of drive shaft coupling solutions. GAM now has three options to cover various motion applications and torque requirements.

Option 1 - EDC
The EDC is rated up to 110Nm of torque and was designed to be an economical drive shaft option, suitable for general motion / lower torque applications.

Option 2 - EKZ
The EKZ is rated up to 700Nm of torque and is the next progression in GAM's drive shaft coupling range.  While still an elastomer style drive shaft coupling, the EKZ is suitable for higher torque applications.

Option 3 - WDS
The WDS is rated up to 1600Nm of torque and is GAM's highest performing drive shaft coupling, intended for dynamic applications that require high positioning accuracies.  It features a torsionally rigid bellows design which yields a 1208% increase in torsional rigidity over an elastomer style drive shaft coupling of a comparable torque rating.

GAMMY Winner - November 2013

Austin was awarded the GAMMY award for the month of November.  He is in charge of GAM's coupling cell and played a big role in helping GAM to hit a record shipping month in September and another great shipping month in October.  All along the way, he displayed great teamwork and professionalism.  For more information about GAM or our core values.

What is an Elastomer Coupling?

Elastomer couplings can be plugged in, are backlash free, flexible shaft couplings for small to medium torques.  An elastomer coupling is typically a three piece design comprised of two hubs and an elastomeric spider.
The elastomer spider (insert) serves as the connection and compensation element with involute shaped teeth and high Shore hardness.  The spider is inserted with slight preload between two high precision machined hubs with matching involute shaped jaws.  The elastomer spider can compensate for shaft misalignments, is electrically insulating and demonstrates good oscillation dampening.

Areas of use for elastomer couplings range from general motion control applications to demanding drive systems in machine design including the spindle and axis drives of machine tools.  To learn more about elastomer couplings visit http://www.gamweb.com/elastomer-couplings.html

What is the GAM EASY-Clamp system?

Because the bore tolerances on couplings are so precise, installing or un-installing a servo coupling can be very difficult.  In fact, machine builders have been known to wedge screw drivers in the coupling hubs to help open the bores up.  Not only is this unsafe but the coupling and/or shafts can be damaged.

A better engineered solution is the EASY-Clamp system which is found on many GAM couplings.  This system allows easy installation without the need for additional tools (screw drivers included).  The EASY-Clamp pin is located just above the clamping bolt.

To engage the system, simply loosen the clamping bolt until it backs out and hits the pin.  This expands the clamping head making installation or un-installation quick and easy.
