When selecting couplings for precise motion applications there are often questions about the most suitable approach for optimizing both performance and economy.

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.
When fluid power and power transmission products are discontinued, finding replacements can be challenging. Zero-Max now fills this Overhung Load Adaptor void with its new 212k and 412k OHLA models for 2-bolt SAE A mount and 4-bolt non-SAE mount applications requiring a 1-1/4” output shaft.
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.
NORD DRIVESYSTEMS will be exhibiting at this year’s CONEXPO–CON/AGG March 14th - 18th in Las Vegas, Nev. CON/AGG is North America’s largest construction trade show and creates one convenient place for attendees to learn about the future of construction technology and heavy-duty solutions from industry leaders. NORD’s construction solutions focus on reliability, high-efficiency, and versatility.
Harmonic Drive announces the release of its HPF series of hollow shaft gear units. Designed for heavy-duty industrial applications, these advanced gear units offer high torque outputs and flexible installation options, making them ideal for use in demanding environments.
Thomson Industries, Inc., a leading manufacturer of linear motion control solutions, has introduced a family of compact linear systems that makes it easier for motion designers to implement complex applications in small spaces. Designers needing thrust and bearing support in a single, compact unit now have the flexibility to build such applications with versatile, time-tested components from Thomson.
Zero-Max did it again – three entirely new Extra-Duty Overhung Load Adaptor (OHLA) models. Based on decades of experience solving overhung load issues in the most demanding applications, the new designs feature a number of carefully chosen upgrades including spherical bearings, enhanced sealing technology, stronger shafts and a longer profile delivering increased operating life, heavy load capacities, and higher speed ratings.
Wachendorff is expanding its range of Ethernet-based encoders: Encoders with the EtherNet/IP protocol are now available, including the most compact in the world: the WDGA58F. Wachendorff's R&D team has succeeded in minimizing the sensor to an installation depth of just 46.5 mm.
A new version of the MESYS shaft and rolling bearing analysis software including new functionality is available. The bearing analysis software allows the calculation of the load distribution within the bearing and bearing life according to ISO/TS 16281 and it is integrated in a shaft system calculation with additional possibilities like modal analysis, strength calculation for shafts and interfaces to gear calculations. Currently the software is used by customers in 30 countries on four continents.
