Based on the proven ROBA-DS steel disk pack coupling, Mayr Power Transmission developed a weight-optimized aluminum version. Compared to the steel version, the outer diameter of this new design has been reduced by up to 10 mm; the mass and mass inertia range from 40 to 60 percent of the steel version, depending on the design and size. The performance density, however, remains unchanged. It is tailored to meet the requirements of high-speed applications, for example in the field of test bench technology.

Regal Rexnord Corporation has added two new models to its portfolio of Boston Gear Gen2 SS700 Series stainless steel worm gearboxes. The new sizes bring the full product lineup to seven. A larger output shaft bore expands the number of applications each model of gearbox can support, providing flexibility and versatility for customers in a range of industries, including food, beverage and pharmaceuticals. 

Demand for specialty wire and cable—fueled in part by data center expansion as well as new charging stations for electric vehicles (EVs)—is in turn creating greater demand for cable production capacity. As you design machines that will satisfy the demand, you’ll want to incorporate an effective driving method that controls speed and torque with the highest precision.

Incorporating electromagnetic clutches into industrial applications brings numerous advantages for enhancing system reliability, functionality, and safety. KEB’s Combinorm power on clutches provide a critical solution by ensuring parts of a machine can engage and disengage as needed, particularly in emergencies.

Ruland Manufacturing continues to expand its motion control coupling product line by introducing bellows couplings with increased misalignment capabilities. These new bellows couplings complement Ruland’s existing high-stiffness line by offering equivalent torque with greater misalignment flexibility.

NSK has developed a practical magnetostrictive torque sensor (3rd-generation sensor) for automobiles which enables failure prediction, a comfortable ride, extension of driving mileage and performance improvement thanks to its weight-reducing and space-saving features, while also shortening the development period.

In the machinery and plant engineering sector, ensuring reliability and performance is now at the forefront. Particularly, manufacturers of machine tools, automation systems, and general mechanical engineering have significantly increased their requirements for high-performance elastomer couplings recently.

Ruland Manufacturing now offers bellows and double disc couplings with bore sizes up to 1-3/4 in or 45 mm for use in systems with torque up to 1,4000 in-lbs. (158 Nm). High torque applications commonly found in precision semiconductor, solar, conveyor, and factory automation applications often use these shaft sizes. Ruland disc and bellows couplings accommodate all forms of misalignment, are zero-backlash, and have a balanced design for reduced vibration at speeds up to 10,000 rpm.

It's no secret that cycloidal gearboxes are important in mechanical engineering, especially when it comes to precision motion control and efficient power transmission. The gear systems differ from harmonic wave/strain wave gearboxes by using a cycloidal disk and needle bearings to transmit torque with minimum backlash, achieve high reduction ratios, and support substantial loads. This Sumitomo Drive Technologies blog will talk about single-stage and multi-stage cycloidal gearboxes.
