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.
Difficult general conditions, rapidly rising food and fuel prices, as well as the ongoing coronavirus pandemic and related regional lockdowns weighed on economic development and slowed economic growth in the past business year. Nevertheless, Liebherr’s total revenue increased significantly compared to the previous year. The group achieved increased revenue in 10 of its 13 product segments, some of them significant. It thus surpassed its previous record from 2021 by €950 million.
The new KISSsoft release 2023 comes with numerous novelties. Among others, Gear Mesh Frequencies (GMF) can now be calculated for cylindrical and bevel gears. GMF results are visualized in two different diagrams, i.e. GMF versus rotational frequency of the reference gear, and GMF versus amplitude.
What started as a small workshop in Antwerp in 1923 has developed into a world-leading industrial gear unit manufacturer. For 100 years, Hansen Industrial Transmissions NV (HIT) has operated at the forefront of power transmission technology and shaped the industry with its industrial gearbox solutions. Since 2011, the company, headquartered at a state-of-the-art facility in Edegem with 260 employees, has been part of Sumitomo Drive Technologies. HIT supplies industrial gearboxes to a wide range of industries such as extraction material handling, energy, environment, and specialist applications in key industries.
Velo3D, Inc. has been named to Fast Company’s prestigious annual list of the World’s Most Innovative Companies for 2023. The company received the award because of how its technology is being used by innovative companies in key industries like new space, semiconductor and energy, which rely on advanced manufacturing technologies to build next-generation products.
Join Gleason's special online event to learn about design, manufacturing and inspection of e-Drive gears. The three day event features one topic per day addressing the specific requirements and challenges of e-Drive transmission manufacture, with particular attention to minimizing gear noise.
The latest version offers a wide range of powerful new features, from a new gear design module, to the influence of the wheel body during a complete rollover, to new display options for 3D images and animation of the gearbox kinematics in reports.
