The Reinvention of the Shear Type Coupling

 

Shear type or sleeve type couplings originated in the 1950s. It is a very popular choice for pump applications where it gained early acceptance and has grown organically across many industries including wastewater, paper/pulp, marine and steel to name a few.Get more news about Elastic Sleeve Pin Coupling Factory,you can vist our website!

The shear type coupling is a very simple design and is comprised of 2 flanges and 1 sleeve. The torque is transmitted through the twisting of the elastomeric sleeve and virtually eliminates the load on bearings and shafts and is excellent with vibration dampening. As with other elastomeric couplings, it is a low maintenance and non-lubricated coupling option.

Lovejoy, Inc. set a goal to redesign the sleeve coupling product and to make it the highest quality and longest lasting offering available at the same competitive price. The result is the S-Flex Endurance^TM, a new and improved, longer lasting EPDM rubber sleeve material.

The new S-Flex Endurance coupling design has undergone extensive dynamic cycling testing. The results of this testing prove the S-Flex Endurance EPDM material provides higher performance and enhanced durability than its previous iteration.

Testing was performed to determine the actual physical performance and torsional capabilities of the new EPDM sleeves. The test articles were installed between the torque actuator's driving S-Flex flange and a driven torque transducer flange. The testing regiment consisted of accelerated fatigue testing where the sleeves were subjected to high frequency start-stop-reverse cyclic loading. The sleeves completed extensive testing at loads greater than the sleeve's torsional ratings. The sleeve's performance characteristics were collected for comparison to the original material and the competitor's product. The static torsional stiffness was repeatedly measured as the slope of a stress-strain curve during dynamic cycling testing. The dynamic torsional stiffness was also continuously evaluated over the full test duration. As an additional performance guide, the competition's equivalent sleeve materials were evaluated as well.
S-Flex Endurance sleeve's static and dynamic torsional stiffness tested at least 30% greater than the former Lovejoy material and outperformed the current products in the market. The S-Flex product operated with more resilience and consequently less heat build-up. Furthermore, post-test inspections showed the new sleeves are very durable under these extreme test conditions, as they maintained their tooth shape and displayed minimal wear.

The Sleeve Life

Test Duration Graph shows that the former EPDM sleeves lasted an average of 747k cycles before reaching torque overload failure where the sleeves failed and could no longer transmit the set torque. The new EPDM material was tested for a week up to about 4.75 million cycles and no signs of failure were present at which point testing was ended. Accelerated fatigue testing is performed at severe high-torque and high-frequency conditions. Typical operation cycle life will greatly exceed the test cycles in the graph. The cyclic fatigue test conditions demonstrate the new EPDM material has at least a 3X longer life expectancy, if not more, than the former material.

Ford patents magnetic charging connector: MagSafe for EVs?

 

Ford has filed a patent application for a new type of EV charging connector based on a magnetic coupling.Get more news about led magnetic connector supplier,you can vist our website!

In the application, which was filed with the United States Patent and Trademark Office (USPTO) November 1, 2022, Ford describes using magnetic attraction to secure a charging connector with a charge port embedded in a vehicle's bumper.Ford envisions this magnetic charging connector being used with both EVs and plug-in hybrids, and with AC and DC charging stations. It also indicated that the magnetic connector could be installed on vehicles along with conventional charge ports.

Lacking a cable, this setup does require maneuvering a vehicle to align with the charging station. To make this less challenging, Ford said in the application that it would design in some degree of articulation to allow a hookup as long as the driver is relatively close to the target.

Ford does consider this to be a form of conductive charging, with a physical connection to transmit electricity, as opposed to the inductive charging exemplified by wireless charging systems. As with MagSafe, the magnetic system will help align connectors.

Getting rid of the physical connection is attractive, too. The recent Ram Charger inductive charging robot does without it, pressing up against a charging pad once aligned below the vehicle but relying on a magnetic field in between. The General Motors EV1 also used a unique Magne-Charge induction charging paddle.
Ford hasn't confirmed plans to use this novel charging connector in future production vehicles. Among the potential problems are the cosmetic (and parking vulnerability) challenge of integrating the charge port with a vehicle's bumper.

The desire to eliminate the fuss of handling charging cables has led to some interesting ideas, such as the snake-like robotic charger Tesla showed in 2015 and quietly shelved. The automaker now appears more focused on rallying other automakers to use its NACS connector, perhaps as part of a push to win federal money reserved for a national charging network. Aptera has confirmed plans to use the Tesla connector, but the automaker's pitch doesn't seem to have generated much interest from other firms.
