In KISSsoft, 97 (yes, ninety-seven!) plastics are available for calculation of cylindrical and crossed axis helical gears. The materials range from unreinforced POMs and PAs to high performance reinforced and internally lubricated materials. 

GWJ Technology GmbH has introduced new versions of its integration modules for Solidworks, Autodesk Inventor and Solid Edge. In addition to comprehensive tooth form output in 2D DXF or 3D STEP/IGES for various gear types, GWJ also offers integration modules for its calculation solutions eAssistant and TBK in various 3D CAD systems.

The loaded tooth contact analysis (LTCA) is crucial in understanding the deformation of gears and its impact on various factors such as noise generation, contact patterns, contact shocks, and torque variations. With the contact analysis feature in KISSsoft, users can calculate tooth contact under specific torque and speed levels, thereby assessing the performance of gears and gearboxes.

Croix Gear, recognized as a leader in the custom manufacturing of loose gears, is excited to announce new branding for the organization. Ruthie Johnston, CEO/Owner, stated, “We are excited to have our brand reflect how Croix Gear has grown and developed over the past several years. It is a new look, but the same commitment to our customers, team members and industry.”

In KISSsoft's scheduled trainings until December 2023, attendees will find introductory training courses, advanced training courses and special training courses on selected topics.

The toothed belt and pulley system known by the designation T, which has been selected as an example within this paper, was developed in the 1950s and standardized first in DIN 7721 (1977) and then in ISO 17396:2014. In this case study, the authors check if a single hob can properly cut T5 profile pulleys with 25 and 30 teeth—and if
so, define the range of the number of teeth covered by this hob.

In the KISSsoft shaft calculation, the proof of fatigue strength can be performed by generating an equivalent stress verification according to the FKM Guideline.

The conjugacy of meshing gears is one of the most important attributes of gears because it ensures a constant velocity ratio that gives smooth, uniform transmission of motion and torque. Some of the world’s greatest gear theoreticians like Earle Buckingham, Wells Coleman, and John Colbourne laid the foundation for understanding conjugacy. Their teachings and interpretations of the law of gearing have been used by generations of gear engineers to design and manufacture gear transmissions for almost everything that is mechanically actuated. 

In an urgent assignment, a gear has to be designed, with the engineer already knowing the required reduction ratio, torque and speed. On the manufacturing side, the preferred materials, possible qualities and the reference profiles are specified. This initial situation represents an everyday task.

In this interview, we learn about Gleason Plastic Gears (GPG), a division of Gleason Corporation that specializes in designing and manufacturing plastic gears using their proprietary no-weldline technology. GPG has diversified its customer base and serves various industries such as automotive, medical, electronics, home and leisure, marine, education, and hobby. The interview covers topics such as the advantages of the no-weldline technology, surprising applications where plastic gears are replacing metal gears, promising materials and methods for the future of plastic gears, challenges faced by plastic gear designers, and recent developments in services, software, and manufacturing technology.
