Disc springs - Import export

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. Chemical resistance Polysorb disk springs are resistant to many chemicals. iglidur® A500 has a higher resistance than iglidur® J. Medium Resistance iglidur® J iglidur® A500 Alcohols + + Hydrocarbons + + Fats, oils without additives + + Fuels + + Diluted acids 0 to - + Strong acids - + Diluted bases + + Strong bases + to 0 + Humidity absorption The low humidity absorption allows them to be used in wet or humid environment. Polysorb® disk springs absorb humidity. Thereby their mechanical properties alter. In the worst application that can be thought of - extremely long application in water - Polysorb® disk springs still exhibit high spring force. iglidur® Standard environment saturated in water J 18 15 A500 24 23 Increased operating temperature Increased temperatures lead to the decline of stiffening in polymers. Polysorb® disk springs exhibit a maximum spring force of 8 N even at the maximum permitted temperature of 80° C. See figure for relationship of spring force to ambient temperature.

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.

FlexDur FD-C-couplings are flexible compensating couplings of all metallic design which transmit the torque in a torsionally rigid and backlash-free manner. The transmission elements are disc packs of stainless spring steel plates which are attached to the coupling components by closetolerance bolts. The most important characteristics and advantages of FlexDur FD-C couplings: Torsionally rigid torque transmission with zero torsional backlash Wear-free compensation of axial, radial and/or angular shaft displacements ittle restoring forces in the case of shaft displacements Neither maintenance, nor lubrication required For use at ambient temperatures from – 25 °C to + 250 °C Compact design even suited for high and very high rotational speeds Infinite life, proper shaft alignment provided We are glad to see that you are interested in our product line and are happy to answer all questions!

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.

The swivel motors with attached hydraulically released spring-applied multi-disc brake are recommended if a swivel position must remain unchanged once it has been reached – even over an unlimited period of time – despite the effect of a load torque. The brake is used solely to hold the load. It should only be noted that large transmission delays in the lines can cause time differences between the switching off of the swivel motor and the application of the released brake caused by spring force. In order to provide our customers with the right drive for all areas of application, the HSB swivel motor is available in a total of 5 different versions. We have listed the most important data below. You can find all further details in our data sheet.
