The combination of these components provides a torsionally stiff connection and accommodation for misalignments. This product is available in materials and elements that are optimized for close coupled applications. Function and Design BoWex® - couplings, suitable for horizontal or vertical applications, are constructed from a variety of materials providing a torsionally stiff platform optimizing the balance between coupling performance and application requirements. The double-crowned tooth reduces edge loading while accommodating misalignments and transmitting torque. The symmetrical relationship of the hubs and floating nylon sleeve allows for minimal maintenance in a close coupled design. The design of the BoWex® allows the nylon sleeve to float independently of the two hubs thus minimizing restoring forces. The result is a double-cardanic coupling with high torsional stiffness, low inertia and chemical resistance while accommodating large axial movement. Unlike other gear couplings, BoWex® does not require lubrication and can be used for shaft to shaft and engine flywheel drive applications. BoWex® is available in a variety of standard mounting options to accommodate shafts up to 4.813 inches and a maximum nominal torque of 22,120 lb-in while still accommodating blind assembly. As defined by the sleeve, BoWex® couplings are suitable for moderate industrial temperature ranges. All these design features reduce the maintenance required during the life-cycle of the coupling. sleeve sleeve hub hub sleeve sleeve Straight tooth hub On couplings with straight teeth, high edge pressure contributes to considerable wear at the contact surfaces when misalignment is present. Double-crowned BoWex® hub The curved teeth avoid any edge pressure on the coupling when angular and radial misalignments occur. Explosion-proof use BoWex® couplings design M up to size 65 including an electrically conductive nylon sleeve (PA-CF) are suitable for power transmission in drives in hazardous areas. The couplings are certified and conform to EC standard 94/9/EC (ATEX 95) as units of category 2G/2D and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22.

If it is difficult to determine the distance dimension “E”, reference may be made to the overall assembled length. The shaft ends to be connected should be supported close to each coupling half. 1) The listed distance dimension “E” must be observed in every case, particularly for parallel and angular misalignments. 2) If the coupling hubs have been shortened or lengthened on the outside, the overall length of the coupling assembled will be reduced by the corresponding figure. 3) The allowable misalignment figures depend on speed and performance. Prior to operation of the BoWex® coupling please make sure that the coupling sleeves are capable of axial movement.

This design features a plug-in assembly that provides considerable system dampening for low driven inertias. This product is available in SAE and Metric flywheel configurations. Function and Design MONOLASTIC® - couplings are constructed from materials designed to provide a torsionally flexible solution in an easy to assemble one-piece design. The rubber element allows for misalignment and some dampening while reducing restoring forces on driven components. The flexible one-piece design enables a compact assembly while reducing the likelihood of fretting and premature wear of the spline connection. MONOLASTIC® is available in a variety of standard mounting options to accommodate flywheels up to SAE 11.5” and a maximum of 185 HP nominal in a plug-in design. They are also available in metric, and engine specific configurations. They are suitable for low inertia drives typically found in hydrostatic applications. BoWex® FLE-PA General description: BoWex® FLE-PA – couplings are designed to transmit torque on flywheel driven applications via a curved tooth hub and nylon engine flange. The combination of these components provides a torsionally stiff connection for low driven inertias. This product is available in materials and elements that are optimized for close coupled applications. Function and Design BoWex® FLE-PA - couplings, intended for flywheel driven applications, are constructed from materials designed to provide a torsionally stiff solution while optimizing the balance between coupling performance and ease of assembly. The double-crowned tooth reduces edge loading while accommodating misalignments and transmitting torque. The compact two-piece coupling design enables the hub to be securely fastened to the driven shaft eliminating the need for lubrication, reducing fretting and corrosion, while allowing for minimal maintenance in an engine drive coupling. The two-piece design of the BoWex® FLE-PA allows the nylon flange to provide high stiffness, low inertia, corrosion resistance, and allows for blind assembly. Nylon flanges are available from stock in standard SAE, metric and engine specific configurations. BoWex® FLE-PA is available in a variety of standard mounting options to accommodate flywheels up to SAE 18” and a maximum of 1,075 HP nominal, while still accommodating blind assembly. They are suitable for low inertia drives typically found in hydrostatic applications. BoWex-ELASTIC® General description: BoWex-ELASTIC® – couplings are designed to transmit torque on flywheel driven applications via a curved tooth hub and elastomeric engine flange. The combination of these components provides a highly flexible connection for large driven inertias. The torsionally flexible connection modifies the torsional profile of the system, moving critical resonance out of the operating range. Function and Design BoWex-ELASTIC® - couplings are intended for engine driven high inertia applications. Constructed from natural rubber, the coupling design provides a highly flexible solution while optimizing the balance between coupling performance and ease of assembly. The two-piece coupling design enables the hub to be securely fastened to the driven shaft, eliminating the need for lubrication, reducing fretting and corrosion, while allowing for minimal maintenance in an engine drive coupling. BoWex-ELASTIC® elements are available in several hardnesses. When the proper hardness is selected, maximum benefit can be achieved between dampening and torque transmission, insuring proper torsional profile for your application. Elastic elements are available in standard SAE and metric sizes. BoWex-ELASTIC® is available in a variety of standard mounting options to accommodate flywheels up to SAE 18” and a maximum of 1,500 HP nominal. They are suitable for high inertia drives typically found in compressors, pumps and generators. 87 BoWex® MONOLASTIC® BoWex® - FLE-PA BoWex - ELASTIC® MONOLASTIC® 003_bowex p69-98_Layout 1 11/28/2012 8:31 AM Page 86 MONOLASTIC® One-piece, flexible flywheel couplings Coupling selection 1. BoWex-ELASTIC® couplings should be selected in accordance with DIN 740 part 2. The coupling must be sized to ensure that the maximum allowable coupling torque is not exceeded during operation. It is therefore necessary to compare the actual loads with the rated parameters of the coupling according to tables 1.1 - 1.4 listed below. For drives subject to torsional resonance it is necessary to review the drive by means of a torsional vibration calculation to ensure proper operation. 1.1 Load by rated torque 1.2 Load by torque shocks The maximum permissible torque of the coupling must, at operating temperature, be as high as the operational peak torque TS, taking into account the shock factor SZ. 3 1.3 Passing through critical resonance TKN ⱖ TN · St The allowable rated torque TKN of the coupling must, at TN [lb-in] = 63,025 · operating temperature, be at least as high as the rated torque TN of the machine.
