SPIROL offers a line of austenitic stainless steel Disc Springs in diameters ranging from Ø8mm to Ø71mm. Austenitic stainless steel is typically used for static and low cycle applications that require a heightened level of corrosion resistance. It withstands fresh water and atmospheric marine conditions very well, and is suitable for many other industrial conditions including acidic environments. This material will continue to work harden with use so cycle life is limited, but creep resistance is good. SPIROL supplies both single Disc Springs as well as Pre-Stacked Disc Springs in custom configurations, packaged in shrink wrap with a perforated tab for easy of assembly.

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!

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 high capacity to consistently store releasable mechanical energy. Visit www.SPRIOL.com to learn more!

DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

Disc Springs are conically-shaped precision components designed to be axially loaded. Disc Springs are often incorrectly referred to as belleville disc springs, belleville springs, belleville washers or simply conical washers. SPIROL offers the full range of DIN EN 16983 (formerly DIN 2093) Group 1 and 2 Disc Springs in Series A, B, and C. In addition to the DIN specified sizes, SPIROL stocks its own standard sizes with outside diameters ranging from Ø8mm to Ø200mm. SPIROL Standard Disc Springs were designed around the standardized calculations of DIN EN 16984 (formerly DIN 2092), and meet all material, dimensional tolerance, and quality specifications as laid out in DIN EN 16983 (formerly DIN 2093) yet offer an expansion in the diameter and thickness combinations that are not included in the DIN standard. Standard materials include carbon steel and alloy steel, both finished with a protective coating of zinc phosphate and oil.

Automatic clamping takes place over disc springs, which are adjustable in the pre-loading and are solved pneumatically to the workpiece change. Manual clamping is made by a knurled knob on the opposite side of the collet. Due to the integration into the existing through-hole of the rotary table, the rotary table with the clamping system remains very compactly. Compact High run-out accuracy Easy to operate Retrofit possible

Disc springs (also called Belleville springs) are geometrically a cylindrical washer with a slightly conical shape. It is used as compression spring and is the best solution when forces are high and travel relatively limited. This type of springs can or in parallel, which increases travel and/or force.

Polysorb Disk springs delivery program De [mm]: Di [mm]: disc springs are annulus discs stressable in the axial direction, which are turned over in the shape of a disc in the axial direction. disc springs provide a more favorable space usage than other spring types. They are particularly suitable for designs that demand a small spring deflection. + When not to use Polysorb Disk springs? For the implementation of specially flat load deflection curves that are possible with metal only with considerable complexity and expenditure (slotted versions). For compensation of axial clearance and manufacturing tolerances For vibration compensation For noise dampening When an antimagnetic material is required For electrical and thermal insulation When no corrosion problems should arise When lubrication is not necessary For low weight For low space requirement – When not to use polyserb disk springs? When constant spring forces are necessary over a wide temperature range When high spring forces are required The spring deflection of the disk spring is relatively small. Therefore a number of disk springs are combined in practice. Alternatively layered disk springs enhance the spring deflection in proportion to the number, whereby the overall spring force is as large as the force of the individual disk spring. To increase the force, the disk springs can be layered in parallel as a spring packet.

Punching units Punching unit with exchangeable cutting elements for sheets and profiles up to a material thickness of 25.0 mm and a hole diameter of 150.0 mm JOKA punching units consist of a special cast stand that accepts the punch and die and ensures the exact axis alignment between the cutting elements (punch and die). In addition, there is a stripping system in the upper part of the tool stand, as the material wipes off automatically after punching. The scraper contains two or more disc spring packages that guarantee perfect scraping even in the border areas. A fixed connection between the tool and the upper part of the press is therefore not required. To determine the exact position, each tool has a positioning pin (two for shaped holes) on the underside, which is precisely aligned with the cutting elements (center of the hole). The above picture shows a complete punching unit without cutting elements and one cutting set (punch and die) each for round hole or shaped hole.

It is recommended that the cam lever is in a vertical position when the collet is positioned in the bore. The function of the clamping system was tested in bores with tolerance H7. All values for retaining force are guide values and are given without safety factor. The suitability for the respective application must be checked by the user. Advantages: Two components can be joined together without tools. The components are perfectly centred in the clamped state. The compact design means that the mandrel collet with cam lever can even be used in blind holes. There are no specific dimensional requirements for the holes. Additionally, the surfaces and design do not need to have any specific properties. Functional principle: The clamping system is inserted in the hole in the open state. At the beginning of the locking process, the mandrel collet expands and clamps itself in the lower component. The integrated disc spring assembly creates a positive down force

With the Therma friction thermocouple you can determine the surface temperature of the brakes while driving. Attaching the mounting adapter puts uniform pressure on the brake disc through the spring-loaded sensor by using a bayonet cap. That perfectly compensates movements caused by centrifugal force and vibrations as well as the volume decrease caused by disc wear while ensuring a valid measurement. The brake disc friction sensor measures the surface temperature of the brake disc. It imparts important insights about the temperature development. That enables an indication about the brake line, intake and temperature radiation. A brake disc that becomes too hot during a race massively loses its effectiveness and deceleration to the accustomed and optimal degree is no longer possible. If the temperature is too high, the brake pads start gassing on top of that.

While the spring leg disc harrow performs more effective shredding and mixing process than the other known disc harrows due to its spring independent disc structure and machine construction, each disc runs separate from each other thanks to its independent bearing. By means of the springs in each disc, the breakage and damages that may occur on the chassis are eliminated by the back and forth movement of the discs when the machine is stuck because of an obstacle. It is less affected by the surface

End spring legs are made of cast and are sealed with plate fins on both sides. Fertilizer and seed pass the hose between flaps and lays on the soil. Because resultant force forces the leg to come out of the soil due to wide penetration angle, sowing depth can be increased with additional loads. This feature shows superiority over other types of legs. Good seed bed is prepared. Disc and spring-type chisel legs when faced with obstacles such as stone clod, tries to get up, but the axe is mounted to the chassis, leg movement does not come up. Should be replaced when axe is worn.

The water staying pressurized in the pipes is released over the fire area after the sprinkler is activated due to fire. The pressurized water system is not only feed contionuously, but also fills in the retard chamber. After the chamber is filled, the pressure switch on the chamber is actuated. The pressure switch sends the alarm information to the fire warning system or the automation system. After the pressure switch is actuated, the water is delivered to the water-motor gong and releases a mechanical alarm.

Havar® is a heat treatable Cobalt base alloy that provides very high strength. The alloy has excellent corrosion resistance and is non-magnetic. Applications have included metal diaphragms for aerospace sensors, metal diaphragms for burst discs, power springs, gap spacers in magnetic heads, and target foils in nuclear physics. Forming cold rolled Havar requires large radius (90° Bend – 8 X thickness) prior to age hardening. The joining can be accomplished using both welding and soldering techniques.The ultimate endurance life is achieved by heat treating the alloy at 1000°F after 80% cold work. The alloy will retain 75% of room temperature strength up to 950°F (Figure 1). Available Sizes: Havar® is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) and widths to 7.5” (190.5 mm). A foil product is available in thicknesses down to 0.000060” and widths of 4.0” (101.6 mm). The material corresponds to UNS R30004.

The Compact Line includes spring-pressure single-disc brakes that can be mounted as complete units to the motor with very little assembly work. The compact design is of advantage when limited space complicates mounting. Electromagnetically-operated spring-applied brakes build up the braking torque when the current is switched off.

The VARIO LINE includes DC spring-pressure single-disc brakes, which can be matched to the individual application due to a wide range of variants. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off. By means of the electromagnetic force or an additionally mounted hand lifting device, the braking effect can be neutralized. Fitting dimensions and the grading of the type series of the VARIO LINE are matched to IEC motors.
