TSC 300 Power transmission couplings technology to replace Universal Joints, jaw couplings and elastomeric couplings

Twin Spring Coupling TSC 300 replacement for universal joints, jaw couplings & elastomeric couplings.

Couplings in any industry have a number of issues to contend with, annual maintenance, fundamental design flaws coming from a century old technology, products have evolved but the technology that makes up the universal joint and jaw couplings has not. Twin Spring Coupling offers something different.

Old traditional couplings verses maintenance free alternatives

Traditional flexible shaft couplings like universal joints, have to be balanced and can only run at angles of 8 degrees or less otherwise you get wear in the bearings within the propeller shaft of the universal joint, the bearing cross will start to wear on the outside which means the bearings will become loose and that creates vibration and with continual wear the ball bearings will fail.

The bearings need also to be constantly greased otherwise the bearings will not have any lubrication, and with them running at high speed the bearing will become hot and seize in their tracks meaning bearing failure.

Coupling bearings dont work in water or dust.

Bearings being very precise instruments also need to be contained to ensure infiltration by any foreign contaminants, as things like water, mud, dust or dirt will again cause the ball bearings to seize in their tracks and this means bearing failure.

Cracked Yokes or hubs another traditional coupling problem

​The other downside to a universal joint are the yokes which the bearings are contained in, the coupling piece of the yokes are quite tough but the section that contains the bearings not so much as they have to hold the bearings, this is a weak point as the bearings are usually less than 2″ across so the machining to contain the bearings is a lot smaller than the rest of the yoke, which means the likely of them cracking is that much higher.

Cracking leads to catastrophic failure and replacement of both the yoke and universal joint is assured. This makes it an expensive repair as with the price of the yoke and universal joint, it is usually cheaper just to replace everything, both yokes and the propeller joint.

Elastomeric couplings have only a very small amount of angular misalignment

Other couplings like Jaw couplings and elastomeric couplings like grid, tire, donut couplings are less flexible than universal joints but are designed to run only at very small amounts of angular misalignment, in the case of jaw couplings and grid couplings less than 1 degree and with elastomeric couplings a maximum of 4 degrees.

The insert components in elastomeric couplings is a shock absorber and vibration dampener in one. This works great at minimal angular misalignment less than .25 of 1 degree. Eventually the insert will need to be replaced due to compression and this means increased vibration and potential hub damage.

If you get to where the maximum misalignment angle is reached then the inserts start to wear at the edges, meaning they need to be replaced sooner than expected, so unscheduled maintenance stoppages and shutdowns occur.

Of the mass market couplings the mechanical designer has been forced to design their equipment around these couplings, not for what the machine can do.

We have something different, a no insert, maintenance free coupling with the flexibility of a universal joint with the high speed of a elastomeric coupling.

TSC 300 power transmission couplings are different.

Twin Spring Coupling is different it replaces the entire joint, yokes/hubs, spider/propeller/cross bearings everything, with a simple one piece design.

Designed with no internal components like bearings, means our coupling is truly maintenance free, making it impervious to water, mud, dust, dirt and other contaminants. This saves time and on annual maintenance bills, no replacing bearings or spider inserts every year.

By being a one piece design also means Twin Spring Coupling wont break like the yokes do in traditional uni joints.

Our coupling is available in all the standard industry splines for easy replacement or retrofit for OEM.
