Klüber Lubrication

Offers Fully-Synthetic Oil for Rail Gearboxes

Klüber Lubrication, a worldwide manufacturer of specialty lubricants, offers Klübersynth GE 4 80 W 140, a fully synthetic high-performance gear oil based on polyalphaolefin (PAO) chemistry that offers high stability and protection even under shock loads.

With Klübersynth GE 4 80 W 140, Klüber Lubrication complements its range of efficient high-performance oils for railway gears. Klübersynth GE 4 75 W 90, with a kinematic viscosity of approximately 130 mm²/s at 40 degrees C, has proven to be successful in the market. For applications requiring an elevated viscosity, Klübersynth GE 4 80 W 140, has a kinematic viscosity of approx. 250 mm²/s at 40 degrees C. This new product concept corresponds to that of Klübersynth GE 4 75 W 90, which is approved by many OEMs, but with a higher viscosity.

Klübersynth GE 4 80 W 140 offers high resistance to scuffing and micropitting as well as good protection against wear on gear teeth and rolling bearings. The shear stability prevents the lubricant film from collapsing, which is essential to protect both gear teeth and rolling bearings.

The low foaming tendency and anti-corrosion properties of the product enable problem-free gear operation. Klübersynth GE 4 80 W 140 offers a much longer service life than conventional mineral oils, due to the excellent aging and oxidation resistance. As a result, service intervals are extended and maintenance costs are reduced.

High-performance gear oils from Klüber Lubrication can be used in spur, bevel and hypoid gears, particularly if API GL4 or API GL5 is required. Klübersynth GE 4 75 W 90 is approved by several gear manufacturers like IG Watteeuw, Voith Turbo, Siemens-Flende, Stadler Rail, Bombardier, CAF and the German railway operator Deutsche Bahn.

Igus

Introduces Bearing that assists in quick, Easy Liner Replacement

Igus has introduced a new bearing, drylin W Exchange, for its drylin W linear system in which the liner can be replaced directly on the rail without dismantling the system.

By using a practical assembly tool, users can push the old liner out of the housing, clip the new one on to the shaft and push it into the housing for a flush fit. The quick and easy swap of liners will save engineers time and money while maximizing machine up-time.

“When changing the liner on the linear glides guide rail, for example where extremely abrasive sand or glass dust is present, the entire linear slide has to be pushed off the rail,’’ said Robert Dumayne, director at Igus. “For linear axes or multi-axis gantries with a toothed belt drive, this requires a high assembly effort and long machine downtime.”

The new bearing housing for the drylin W linear system ensures easy changing of the liner directly on the linear rail. The side cover of the bearing housing on the linear slide can be removed easily with a screwdriver. The liner is pushed out of the carriage and removed. The replacement liner, which is made of highly wear-resistant and abrasion-resistant iglidur J200 tribopolymer material, is clipped on to the rail and inserted precisely into the slide with the assembly tool. The change is completed by putting the side cap back on the bearing housing. The assembly tool is supplied free of charge, and it can be 3D printed.

The practical benefits of the drylin W Exchange is that the rail cannot be damaged, and replacement takes place directly on the system. A pin in the middle of the side cover secures the liner on the carriage. It can also be replaced using a screwdriver. In this instance, igus provides special recesses on the new liner and in the carriage.

The new Exchange bearing housing can be retrofitted to all existing drylin W systems of size 10 with a shaft, including guides, linear axes and linear robots. Additional sizes are currently being planned.

Rheintacho

Provides Sensor Options for Electric Drives

The FQ, FP, FM and FK mobile electric drives from Rheintacho are equipped with a proven differential-hall technology for safe and reliable detection of rotational speed even in critical electrical and magnetic environmental conditions. The 2-channel design allows not only detection of rotational speed but also the direction of rotation.

In the price-sensitive market of electric drives, users can choose these sensors to match their needs regarding: the required signals, the necessary protection class for their specific applications, an interface via cable, a connector integrated into the sensor body and a wide variety of cable lengths and connector types.

The sensors can be used in a wide range of temperatures (up to +140 °C) due to the housings made of high-quality plastic as well as other constructive measures. The housing material used has exceptional mechanical properties. For example, compression strength and material durability reach values that already allow for substitution of metal housings depending on the respective application. Among other features, the electrical structure provides a very wide range of possible supply voltages and a high level of EMC stability. The Hall elements which are used cover a wide frequency range. The geometric design as flange sensor automatically ensures the proper installation position required for good signal determination.

The FK series has proven over the last decade as a kind of world-standard for speed detection inside electric drives. The FM series features connectors integrated directly into the sensor housing to its sensor portfolio. The sensor is made of a proven high-tech-plastic. The FP series comes with completely new designed sensor electronics resulting in standstill detection and high-temperature resistance. The FQ series achieves the high protection class of IP69K.

GWJ Technology

Celebrates 15 years of eAssistant

GWJ Technology GmbH from Braunschweig, Germany, is marking the 15th anniversary of its web-based calculation software eAssistant - the engineering assistant. The eAssistant software allows calculation, design and optimization of machine elements, including shafts, bearings, gears, different shaft-hub connections and bolted joints etc.

After several years of development, eAssistant was released in 2003 during Hannover Fair. Dial-up Internet was literally the only kind of Internet modem back then. The actual release was in May 2003 and included three calculation modules for shafts, rolling bearings and interference fits. The development process of the eAssistant continued thanks to the positive market response.

Further modules for parallel keys, serrated and splined shaft connections as well as involute splines were added in 2003 and 2004. At the Hannover Fair 2005, the first version of the cylindrical gear pair was introduced. Even back then, this module already included the real gear tooth form based on a mathematical simulation of the manufacturing process. Based on this, the first 3D CAD plugins for Solidworks, Solid Edge and Autodesk Inventor were implemented shortly afterwards. This was followed by the release of an English version and other gear modules.

Single cylindrical gears, cylindrical gear pairs, planetary gear trains, three- and four-gear train systems, gearracks, bevel gears as well as worm gears can now be determined. eAssistant provides different standards in order to calculate the load capacity. DIN 3990/ISO 6336 Method B or ANSI/AGMA 2101 are available. Calculation modules for bolted joints, timing belts, clamp connections and bolts and pins are also part of the eAssistant.

By the end of 2012, GWJ reached another major milestone SystemManager, a true software application for complete systems of machine elements, was released. It runs as a classic desktop application, including FE libraries. The individual system elements are directly linked to the eAssistant calculation modules. The software engineering process of eAssistant and SystemManager is heavily influenced by user feedback to improve the software quality. The applications are constantly being developed.
