5 #DriveLineHarmony www.jbj.co.uk/spider-couplings.html Jaw-in-shear Couplings Selection Process Jaw In-Shear Coupling Selection Process The selection process for determining the proper Jaw In-Shear coupling size requires using the charts shown in this section. There are four components to be selected, two hubs, one elastomer spider, and one ring. Information necessary before a coupling can be selected: ■ HP (or kW) and RPM oroTrque of Driver ■ Shaft sizes of Driver and Driven equipment and ■ Corresponding keyways ■ Application description, including operation details ■ Environmental conditions (temperature, space limitations, or corrosive/chemicals) Steps In Selecting A Jaw In-Shear Coupling Step 1: Determine the Nominal/Torque (Tkn) of your application: in-lbs = Tkn = (HP x 63025) RPM Nm = Tkn = (KW x 9550) RPM Step 2: Calculate your Application Service Factor using charts on this page. The total Service Factor (K) will be: K = K1 x K2 x K3 Step 3: Calculate the Design Torque (Tkmax) of your application. Design Torque = Nominal Torque x Service Factor: Tkmax = Tkn x K Step 4: Use the Jaw In-Shear Torque Rating table on page 6. Scan down this chart to the first entry where both the Tkn and Tkmax torque values for the coupling size are greater than your application. Once this coupling size is determined, ensure that your application does not exceed the maximum RPM or maximum bore size for that hub. Step 5: Once the coupling size, maximum RPM and maximum Bore has been verified, refer to pages 7 and 8 for dimensional data.

Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level.
