Engineers can define flank modifications, such as end relief, and both symmetric and asymmetric lead crowning. Both full-depth teeth and stub-tooth gears are possible. Additional chamfer can be part of the gear design calculation. The allowances for tooth thickness and center distance can come from a database or be defined individually. The latest release also includes a variety of enhancements to the program’s 3D exports to common CAD packages, such as Autodesk Inventor 2016, Dassault Systèmes SolidWorks 2015, PTC Creo Parametric 3.0, and both Siemens PLM Software NX 10 and Solid Edge ST7.Ĭylindrical gear pair designs, for example, follow DIN 3960, 3961, 3964, 3967, 3977 and 868. In January, a new algorithm was introduced for shaft calculations, yielding increased stability, better performance, and easier fault correction. Moreover, the load and speed direction of each element can be considered separately. In March, reports from load spectra calculations became available for beveloid gears these reports show the values for partial damage per load element. The resulting output includes the contact pattern, transmission error, stress distribution, and the risk of flank fracture. In June, flank modifications were added to bevel gear designing. For instance, flank modifications used to be assessed in a contact analysis under load, which also accounted for mounting deviations and tooth deformations. KISSsoft gets updated all the time, with the latest release dated March 2015. Today, these benefits come not only from the features found in gear design software, but also from the availability of the software on so many different computer systems: standalone desktop, part of a desktop suite, online, and even software as a service. Gear design software provides so many benefits, continues Romax, including “more rapid gearbox concept modeling and analysis, fewer errors, improved processes, reduced rework, faster time to market, and lower overall development costs.” “For the engineering teams tasked with developing new powertrains, resources are being pushed harder than ever and development processes are now very much under scrutiny,” say officials at U.K.-based Romax Technology. Getting a handle on this variety in gears-what’s called designing and engineering-is crucial for the proper working of increasingly sophisticated and efficient moving machines, including electric and hybrid vehicles, wind turbines, consumer appliances, aerospace and defense, and so much more.
