GWJ Technology GmbH has presented a new version of its desktop solution TBK with numerous enhancements, particularly in the field of gearing. The TBK calculation software has been used successfully worldwide for more than four decades to dimension gears, shafts, connections, bearings, and other machine elements as well as complete gearboxes. With its various interfaces to 3D CAD systems, the TBK software is a powerful calculation tool for development, design, work planning, production, and quality assurance.

In the latest version, the load capacity calculation according to DIN 3990 and ISO 6336 has been revised and expanded in the calculation modules for cylindrical gear pairs, planetary geartrains, 3- and 4-geartrain systems and gear racks. It is now possible to individually specify additional factors such as the roughness and lubricant factor as well as the velocity or size factor. Furthermore, the calculation in the fatigue strength range has been improved.

In addition, a detailed verification of the load capacity calculation according to ISO 6336:2019 was carried out using the eight practical examples from ISO/TR 6336-30 published in December 2022. The comparative calculations performed provide very good correlation with the examples from ISO/TR 6336-30. In all eight examples, the absolute deviation of the calculated safeties is ≤ 0.01. These results once again show the high quality of the TBK calculation modules.

Furthermore, the wear resistance according to VDI 2736 for dry running plastic gears was added to the cylindrical gear pair, gear rack and geartrain system modules.

In response to many user requests, the old DIN 3967 from 1953 for gear tolerances and tooth width dimensions, which has been withdrawn for many years, has been integrated into the calculation modules for single cylindrical gears, cylindrical gear pairs, planetary gear trains, gear train systems and gear racks. The number of decimal places for the input fields can now also be configured individually in these modules.

For the design layout available in the cylindrical gear pair and planetary stage modules, additional options have been implemented for the variant calculation, such as “Allow specific sliding > 3” or “Allow small geometry errors”. The result variants can now also be exported in CSV format.

In addition to the splines according to DIN 5480, ISO 4156, ANSIB92.1 (imperial version), ANSI B92.2 (metric version) and DIN 5482, the French standard NF E 22-141 from 1955 is now also supported in the involute spline module. In doing so, the Primary Series was included as the recommended preferred series of NFE 22-141 for flank-centered splined shaft connections with a flat bottom with the associated tool reference profiles and tolerances.

The calculation of hypoid bevel gears, i.e. bevel gear pairs with offset, is now possible with a new calculation module.

In addition to the new TBK version, new versions of the CAD plugins for Solidworks, Solid Edge and Autodesk Inventor are available. Besides the additional generation of 3D rotation surfaces for tip, pitch, and root circles, these offer completely new and extensive options for the automatic generation of tables with the gear data on manufacturing drawings.

Combined Bearing：

Composite bearing is a kind of roller bearing which can bear both radial load and axial load. The structure of the combined bearing is axial and radial bearing running at 900 °, the main load is borne by the radial bearing, and the axial bearing bears the lateral thrust.

Combination bearing is used together with profile guide rail or channel steel. There are two main types of profiles, I and C profiles. The combined bearing slides into the profile guide rail to generate the required linear movement. The combined bearing is welded with the flange plate for installation according to the application requirements. The assembly is mainly used for precise heavy vertical and horizontal movement.
