High Torque Capacity Coupling Resists Axial Motion

Schmidt-Kupplung is offering the axially fixed Loewe GK Torque, designed for torque applications where the coupling has to resist axial motion. The coupling combines the technical features of a single universal joint and a shaft coupling. The crossed pins slide in the plain bearings, which allow a pivotal and radial displacement of the two anodised aluminium hubs with lowest side and bearing loads.

The series GK Torque is available with outer diameters ranging from 27mm to 100mm and with a torque range up to 220Nm. Anodised aluminium clamp hubs ensure a press-fit shaft connection. For higher torque requirements, a special customised steel version of the axially stiff coupling is realised. This coupling size has an increased outer diameter and a torque capacity of 600Nm.

Alloy Resists Heat And Corrosion

Etching is a controlled corrosive process and Inconel has been developed with a high nickel and chromium content, specifically to resist corrosion. The Inconel 617 nickel-chromium-cobalt-molybdenum superalloy offers excellent high-temperature strength and oxidation resistance It also exhibits excellent resistance to a wide range of corrosive environments, which to date have largely prevented the material being photo etched

Etching is a controlled corrosive process and Inconel has been developed with a high nickel and chromium content, specifically to resist corrosion.

Processing thin sheet Inconel by conventional means (punching and slitting) has always given cause for concern as parts tend to come out wavy and the material has a tendency to roll at the edges after processing. Now, thanks to this by the Precision Micro Technical Team, perfectly flat, precision parts can be produced from 0.006in Inconel sheet, economically and with outstanding repeatability.

Epoxy-Resin System Resists High Temperatures

Cures to a tough, strong solid with excellent long term durability and chemical resistance even when exposed to adverse environmental conditions. Master Bond has developed a high-temperature-resistant epoxy-resin system called EP121CL for service up to 260C The two-component optically clear low-viscosity epoxy-resin system features high thermal stability, superior electrical insulation properties and outstanding dimensional stability for casting, sealing, potting, encapsulation and impregnation applications.

Especially noteworthy are its mechanical properties of 83MPa in tensile strength, 119MPa in compressive strength, and its exceptional electrical insulation properties including, a volume resistivity greater than 30Tohm-cm, a dissipation factor of 0.020 at 1MHz and a relative permittivity of 3.34 at 60Hz. EP121CL is an elevated temperature curing epoxy resin system that passes NASA's low-outgasing test.

It cures to a tough, strong solid with excellent long term durability and chemical resistance even when exposed to adverse environmental conditions. There is no cracking or separation of properly cured EP121CL resin from metal, glass etc, over a wide temperature range. Having excellent optical clarity it can be used in optical and fibre-optic applications. The two components are storage stable and after mixing have a working life of 2-3 days at ambient temperatures.

EP121CL is also available in one component and thermally conductive versions. It comes packaged in premixed bipacks and cartridge/gun applicators for convenient dispensing as well as in pint, quart, gallon and 5 gallon containers. Master Bond has developed various "low outgssing" epoxy resin based adhesive systems manufactured with exceptionally high quality standards.

Master Bond's speciality low-outgasing systems include those that are optically clear, cryogenically serviceable, electrically conductive, thermally conductive/electrically insulative and high temperature resistant. Some formulations have been tested by NASA authorised facilities, whereas others have been independently tested.
