GWJ Technology Presents New Version of TBK Calculation Software
GWJ Technology GmbH has presented a new version of its desktop solution TBK with numerous enhancements, particularly in the field of gearing. 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-gear train 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.
Profile Shift
The objective of this report is to determine the origin of the phrase “profile shift.” Several technical books, technical papers, and industrial standards were reviewed for nomenclature associated with profile shift. The phrase “profile shift” translates directly to the German term “Profilverschiebung,” which originated in the last quarter of the 19th century. At first, profile shift was used to avoid undercutting pinions with small numbers of teeth. Later, it was recognized that profile shift improved the gear mesh's load capacity and extended manufacturing tools' service life.
