DISC SPRINGS t ho Di De lo DISC SPRINGS Disc Springs are conically-shaped, washer-type components designed to be axially loaded What makes Disc Springs unique is that based on the standardized calculations of DIN EN 16984 (formerly DIN 2092), the deflection for a given load is predictable and the minimum life cycle can be determined Disc Springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling They can be used singly or in multiples, stacked parallel, in series or in a combination thereof The advantages of Disc Springs compared to other types of springs include the following: • A wide range of load/deflection characteristics • High load capacity with small deflection • Space savings – high load to size ratio • Consistent performance under design loads • Longer fatigue life • Inherent dampening especially with parallel stacking • Flexibility in stack arrangement to meet your application requirements

In most cases, braking occurs when pressurized fluid compresses stationary friction Discs against plates that rotate with the drive shaft The amount of friction between each set of plates controls the deceleration of the vehicle Without an additional fail safe system, this design alone has limited reliability If a hydraulic seal is compromised, or the hydraulic cylinder loses pressure for any reason, the brakes fail Solution: The mechanical back-up design uses SPIROL Disc Springs Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes The reliability of this safety system is dependent on the consistent performance of Disc Springs In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety SPIROL Disc Springs have a consistently high capacity to store potential mechanical energy The conical design of SPIROL Disc Springs makes their spring characteristics and performance more predictable than traditional compression springs Disc Springs are also capable of providing more force in less space than a compression spring or wave spring They are commonly stacked in multiples to achieve application specific spring rates: a stack in series provides less force over more travel; a stack in parallel provides more force over less travel The precise tolerances of each individual Disc Spring provides unparalleled performance predictability when they are stacked (either in series or in parallel) SPIROL Disc Springs also allow fatigue endurance to be predicted Stress analysis enables the minimum cycle life of Disc Springs (singularly or stacked) to be calculated as a part of the application’s design 16 DISC SPRING APPLICATIONS Pick-Off Unit for CNC Machines Application: Pick-off spindles in CNC screw machines are designed to hold a part as it is cut to length and then finished The spindle uses a collet to release the part when it is complete and then clinch a new part When the machine is setup, the clamping force required to hold each part in the collet must be precisely calibrated to prevent the finished product from slipping (if the force is too low) or being crushed (if the force is too high) This calibration is dependent on the geometry and material of the final product After calibration, the quality of the finished product relies on a consistent clamping force for thousands of cycles at a time Solution: Left: Disc Springs are compressed, collet is open Right: Disc Springs are uncompressed, collet is closed, work piece is clinched This high degree of reliability is provided by SPIROL Disc Springs When the collet is opened, 16 SPIROL Disc Springs stacked in series are compressed by a hydraulic cylinder Each time the force from the cylinder is released, SPIROL Disc Springs provide a consistent force to close the collet on the part Pipe Supports for Industrial Pipe Systems Application: As mandated by the ASME code for pressure piping, proper design and installation is critical for the performance and safety of piping systems Industrial pipe systems are primarily supported by rod hangers, base line or base elbow supports While these static supports are used to carry weight, dynamic supports are necessary to control loads on the pipe system Solution: For example, in heat exchanger applications, SPIROL Disc Springs are used to accept thermal dynamics As the temperature of the fluid within the pipe changes, the pipe will expand (when hot) and contract (when cold) accordingly SPIROL Disc Springs support the system by maintaining a constant pressure at any temperature This consistency is transmitted to the pipe joint and is essential for maintaining a proper seal A well sealed gasket prevents fluids from escaping and reduces costly maintenance SPIROL Disc Springs offer an advantage to coil springs by providing an equivalent displacement in a fraction of the space In many instances, such as under a heat exchangers bottom flange, this space savings is required SPIROL Disc Springs are the solution to providing a robust, maintenance free support system for industrial pipe systems Disc Spring Coil Spring A coil spring cannot provide the proper support given the limited space in this example Only a Disc Spring stack is able to package the required load and travel in the restricted space Innovative fastening solutions Lower assembly costs Americas Technical Centers SPIROL International Corporation 30 Rock Avenue Danielson,
