Nexen Group, Inc., announced a new line of Rotary Indexers. The X-Line delivers up to three times more torque and greater moment load capacity in a compact package.

GWJ Technology GmbH, a calculation specialist from Braunschweig, Germany, added new functions to the gear modules of its eAssistant web-based calculation software, which has been successful for more than 20 years.

Siemens Digital Industries Software and IBM recently announced they are expanding their long-term partnership by collaborating to develop a combined software solution integrating their respective offerings for systems engineering, service lifecycle management and asset management.
  

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.

Welcome back to Part 2 of our inner ring and creep discussion. We left off with our creep calculation resulting in a 10.5 µm minimum inner ring fit to avoid creep. For the sake of making clean dimensions, let’s call it 10 µm on the lower end and the upper end is simply whatever your manufacturer can hold.

Precision flexible shaft couplings come in two basic forms, both of which are designed to operate without backlash or excessive inertia while compensating for inevitable misalignment offsets between motor/gearbox and load. Torsionally stiff couplings are made with metallic flexible elements and with the intent to eliminate as much twisting deflection as possible so that the rotation of both shafts is kept as well synchronized as can be. 

PTE will feature a variety of new component technologies online for bearings, motors, couplings, brakes, gear drives, and motion control systems leading up to Hannover Messe 2023 in Germany. Here is a preview of some bearings suppliers to check out if you're planning on attending the event online or in-person in April.

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.

This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.

For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.

I think I spend more time talking about ball bearings today than at any other time in my career. Ball bearings have always had a large place in automotive, but not typically in high demand positions—other than a few niche areas. High demand positions, such as axles and planetaries, were typically reserved for tapers, needles and cylindricals. The landscape is changing quickly.
