WIRE ROPE VERSIONS ADDED TO VIBRATION DAMPER FAMILY OF MOUNTS AND BUFFERS
A wire rope series has been added to Elesa’s otherwise rubber-based vibration damper family of mounts and buffers, which are used throughout industry for isolation of equipment where vibration is a major issue. The new AVC series
incorporates AISI 316 stainless steel wound into helical loops where the spring damping function
is derived from innate elastic and friction properties of the rope construction. This allows a high range of deformation suitable for use in mounting of gensets, robotic mounts, stabilising platforms, e.g. for cameras and liquids. Other applications include mounting of electrical cabinets, HVAC, transport platforms, marine equipment, power systems, pumps, desalination, rail, naval, military, marine oil and research platform equipment. Designed for mounting in horizontal or vertical orientation, these are
manufactured in stainless steel so can be used in a wide range of temperatures and environments. Their high range of deformation in comparison to other materials is coupled with the level of resistance to age and atmospheric conditions expected from stainless steel. According to the company, they are excellent for shock attenuation as they operate with low natural frequencies to give a fast damping effect which is resistant to fatigue and are maintenance free. Wire rope mounts/isolators in the AVC series offer a very cost effective,
long-term solution in load capacities from 50N to 3000N, without the need for regular maintenance or replacement.

COUPLING’S DESIGN DAMPENS VIBRATION AND SHOCK
Quick Flex elastomeric couplings from US power transmission specialist, Lovejoy, Inc., are now being manufactured in Werdohl, Germany. Available in multiple cover and insert configurations, these durable couplings are easy to install and require no lubrication. Suitable applications are motor to gearbox, gearbox to driven equipment, and motors to pumps, plus any drive shaft to driven shaft application; and typical industries for their use include steel mills, food processing, pulp and paper, mining, as well as oil and gas. A stainless steel version is available for harsh environments;
and solid and split covers are designed to accommodate higher speeds and increased torque. Inherently balanced from precision machining for high-speed applications, their design dampens torsional vibration and shock to help extend life of the coupling and surrounding components. Quick Flex couplings operate without any metal-to-metal contact. Because the metal hubs don’t wear, the elastomeric insert is the only spare part needed. The inserts help reduce downtime and replacement costs because inserts can be exchanged without moving or disassembling the driving or driven equipment. Quick Flex couplings are available in twelve product families
COBOT HELPS AUTOMATE MANUFACTURING FOR A SPRING AND WIRE FORM PRODUCER
As a family-run business established in 1895, JB Springs operates from 27,000ft2 purpose-built premises dedicated to the production of springs and wire forms for sectors including medical, electronics, aerospace and automotive. During 2020, for example, the company manufactured springs for ventilators and hospital beds. To stay at the forefront of spring manufacturing in the UK, the company has
invested in technology including a Wafios BM6 CNC wire-bending machine which produces 3D wire-form components in batches of thousands, and then more recently a Universal Robots UR10e collaborative robot. The cobot offers high payload of 10kg and 1300mm long-reach and is proving
popular for applications that include machine tending, palletising and packaging. Completing this highly flexible and reliable robotic solution is a Robotiq 2 Finger 85 adaptive gripper. With a Plug + Play kit for Universal Robots, this easy to customise gripper gives full control to users who can adjust the gripper’s position, speed and force to give a perfect grasp, the company explains. Since installation at JB Springs, the UR10e has been busy automating production on
the Wafios BM6, which is fitted with a Keyence high-speed inspection camera. In one example application, 12mm diameter pre-galvanised wire forms receive four bends in a nine-second cycle time before being unloaded and packed by the UR10e. Alex Driver, managing director at JB Springs, said: “The robot picks and packs parts
neatly, saving a massive amount of costed manual labour. Our wire forms can vary from simple hooks and brackets through to complicated linkages for machinery, precision components for electronics and medical equipment, automotive parts, and welded assemblies for production line systems. We use the UR10e wherever we possibly can and it’s a perfect example of how technology is helping us to constantly improve our manufacturing efficiency and accuracy.”

16 DECEMBER/JANUARY 2021 | DESIGN SOLUTIONS
ranging from bore sizes of 10mm to 280mm. They are designed for continuous torque levels from 43Nm to 188.8kNm and peak torque levels from 85Nm to 377.5kNm, and can accommodate shaft misalignment up to 2˚. Split cover options help resist axial separating force under high torque, while standard and double-ended spacer couplings are available for shaft separations of 25mm to 3000mm. Four insert choices are offered for varying torque needs and temperature ranges up to 177˚C. The couplings are made with four bore options: bored, keyed and set screws style with clearance and interference fit, bushing style, splined style, and mill motor style.

SYSTEM FOR ELECTRIC VEHICLES An advanced semi-active suspension from DRiV that senses and adapts to changing road conditions for a more controlled and comfortable ride is a feature of Volkswagen’s ID.3 electric vehicle. The ID.3 model can be equipped with a
Continuously Variable Semi-Active suspension with external valve (CVSAe), one of several electronic suspension technologies available through DRiV’s Monroe Intelligent Suspension portfolio. The system senses and continuously adapts to changing road and driving conditions via four electronically controlled dampers. An electronic control unit (ECU) processes various sensor inputs and controls the electronic valve on each damper. The driver can select a preferred driving mode, either Comfort or Sport, to experience the desired ride and handling characteristics.
