New Version of Calculation Software for Gearboxes

Software company GWJ Technology GmbH, headquartered in Braunschweig, Germany, has launched a new version of TBK, its calculation software for machine elements and gearboxes. In addition to a significant speed improvement, especially at startup, the latest TBK version is loaded with new features and enhancements.

One example is the new menu item "New". Clicking the menu item "New" closes the current calculation and opens the calculation module with the internal TBK default setting for all values.

The calculation modules "Cylindrical single gear“, "Three- and four-gear train systems“ as well as "Gear rack" have been enhanced. The modules now include DIN 58405 for fine mechanics, ISO 1328 and ANSI/AGMA 2015 in addition to DIN 3961 for gear tolerances/gear qualities.

The SKF bearing selection in the bearing module has also been updated. The new filtering function enables user to search for "Popular items" easier and faster. Popular items have a high level of availability and generally provide a cost-effective solution. The new release also adds SKF Explorer bearings. The Explorer bearings are marked which makes it much easier for customers to select the right bearing. There is also a new direct link to open the SKF online catalogue.

For the DXF output of the 2D gear tooth form, a new function for setting the minimum point distance has been added to all gear modules. This makes it easy to set the accuracy and point density for the output of the tooth form in order to use it for wire and laser cutting.

Data reuse seems like a topic that’s been covered for a long time, especially in the industry 4.0 era. With the integration of the standardised GDE format into the modules for gears and involute splines, TBK takes a step closer to a seamless data workflow.

GDE stands for Gear Data Exchange. This format, which is defined in VDI/VDE guideline 2610, is already supported by many measuring machine manufacturers. With the GDE format, geometries of cylindrical gears and involute splines can be loaded directly from the software into the measuring machine. It only takes a few clicks to create a measuring program. This avoids transmission errors and allows to work with standard measuring instructions. By means of the GDE format, data transfer to cutting machines could be also an option.

GWJ is Celebrating 15 Years of Providing Web-based Calculation Software

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, gear racks, 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.

System Calculation Enhanced With New Features

SystemManager is an extension to the web-based calculation software eAssistant (web solution) and TBK. eAssistant and TBK have been around for many years now and are among the most popular software solutions in the business today. SystemManager is a true software application for complete systems of machine elements, i.e., the software is a coupled FE calculation of multi-shaft systems with gears as non-linear coupling elements.
The new version provides an alternative method of importing and automatically meshing housings and planet carriers. This offers an even better mesh quality and allows a meshing of very complex geometries, for example the geometries of gearbox housings in automotive applications are known to be very complex.
The system calculation considers now rotating 3D elastic parts for the calculation of eigenfrequencies (e.g., of planet carriers) using modal reduction.
Coupling connections were added in addition to the previous connection types cylindrical gears, planetary gear trains, bevel gears, worm gears and belts. It easily allows to consider hydraulic or electric connections between subsystems.
Many small extensions had been added like splitting or merging shafts in addition to copy, shift or mirror options. All bearings types are now drawn with separated inner and outer rings in 2D and 3D views. The animations for 3D mode shapes therefore allow a better understanding of the movement in the bearings.
Graphics can be frozen inside the program to allow comparisons and a copy option using the system clipboard was added for graphics for quicker transfer into other documents. The default format for reports is now PDF/A instead of standard PDF. The software documentation is now available as context sensitive help allowing faster access of information to certain inputs.
There are other new additions to the integrated bearing calculation.

Motor Spindle Safety System MS³

The most common accidents involving the use of machine tools include spindle crashes. Common causes include programming errors, incorrectly defined tools, disregarded interference contours, or unintentional high-speed operation. The forces involved are so enormous that components of the motor spindle, ceramic spindle bearings, shafts, encoders, clamping system and the entire machine geometry can be affected or even completely destroyed. A case study from RWTH Aachen shows that repair costs after a crash in the amount of five-digit euro amounts are not uncommon. Collision avoidance systems for machine tools minimize damage and reduce downtime and repair costs in the event of a collision. Nevertheless, only very few machine tools have a spindle collision protection at all. This is usually based on compression elements that act like a car bumper and are completely destroyed in the event of a crash.

Although the spindle components remain intact, downtime still occurs. The motor spindle protection system MS³ from JAKOB Antriebstechnik GmbH detects collisions by means of several sensors and reports them electronically to the machine control. This can bring the feed axes of the machine tool to a halt with measures such as braking and reversing the drives. But beyond that, the motor spindle protection system can immediately interrupt the power flow at the interface between the spindle box and the motor spindle by means of 3D deflection in the event of a collision-induced overload, even before the electronic emergency stop, mechanically and energy-autonomously.

This effective combination of mechanical protection system and active electronic sensor monitoring makes the system superior to purely electronic collision avoidance systems and effectively protects the shock-sensitive components of the motor spindle from the high force peaks of the collision. The resulting kinetic energy of the crash intercepts a built-in shock absorber. The difference is made by a double flange system with built-in permanent magnets. They can guarantee the required high holding forces and rigidity. During the disengaging process, compression springs guide the motor spindle and then return it to its original position. The downtime is limited to the exchange of tools, additional external service is no longer needed. The system is energy self-sufficient, maintenance-free and adaptable to all common motor spindle geometries.
