Humanoids and cobots are rapidly serving the needs of the warehouse, logistics, material handling and packaging sectors allowing skilled workers to turn their attention to more pressing matters on the shop floor. According to MasterControl (matercontrol.com) digital transformation is revolutionizing life sciences manufacturing, driving key trends in the pharmaceutical and medical device industries.
The load limit diagram of a motor spindle serves to graphically represent the permissible operating range as a function of parameters such as rotational speed. It enables a quick assessment of the conditions under which the spindle can be operated safely and reliably without exceeding mechanical, thermal or dynamic limits. Such a diagram is a key tool for the design, selection and evaluation of spindle systems in mechanical engineering particularly in the field of machining where high demands are placed on precision, performance and service life.

Bosch Rexroth continues to expand the ctrlX platform with new capabilities and automation enhancements. The control platform ctrlX COREplus is now available with AI functions on all performance levels. In the area of motion and drives, Bosch Rexroth is presenting compact, energy-efficient, and cabinet-free drives from the ctrlX DRIVE portfolio, which cover virtually all performance ranges. These are complemented by the Motion, CNC, and Robotics software ctrlX MOTION, which is ideal solution for automating production machines and systems. PTE recently had a great conversation with Garrett Wagg, product manager, controls at Bosch Rexroth on new developments in mobile robotics.

Mechanical engineering develops the scientific and mathematical principles behind physical machines, but you can’t help feeling a little real-world magic taking place in the manufacture of components needed for large, heavy industrial applications. Cement production, for example, relies on gigantic equipment to grind raw materials using rotary kilns, ball mills, vertical mills and crushers.

The call came into Atlanta Gear Works like any other—a vertical mill drive used for a crusher application in cement needed a gearbox upgrade. The difference this time was the sheer size and scope of the gearbox in question. Similarly-sized gearbox rebuilds could take a month or more to complete, but Atlanta Gear Works had 14 days to complete this rebuild—counting weekends—with a tight schedule leaving no room for error.

This paper examines the selection process, operation, maintenance practices, and state of a Sumitomo gearbox after over 24 years of operation. It is demonstrated that a quality product and careful consideration of all these factors are essential for a longer service life of the gearbox. Detailed information is provided on the operation of the gearbox, as well as the maintenance practices that should be taken to ensure its longevity. Finally, the paper examines the state of the gearbox after over two decades of use and how all these factors result in lowering carbon emissions.
In the realm of tractor gearbox applications, gear whine noise has long been a persistent challenge that significantly impacts the user experience and overall perceived performance of the vehicle. This paper delves into a comprehensive study that discusses the approach to tackling this issue through a combination of design optimizations, simulation techniques and physical validation processes.
For over two decades, our Montreal-based engineering simulation consultancy has provided advanced solutions to a diverse range of industries. Our expertise has facilitated the resolution of complex engineering challenges, leveraging the latest technologies in computational fluid dynamics (CFD) and heat transfer analysis. Among our recent projects, one particularly notable case involved a company specializing in converting combustion engine vehicles to electric vehicles.
The drive system choice is dependent on key motion features of your application. Lead screws offer self-locking capabilities, while ball screws require brakes to prevent back-driving. The choice between them hinges on efficiency, cost, precision, and speed, with the screw drives themselves paired with a linear guide for optimal performance.
Bellows couplings are commonly used in applications requiring precise rotation, high speeds, and dynamic motion transmission. With zero backlash and a high level of torsional stiffness, they offer clear performance advantages in many servo-driven systems.
The Simplicity self-lubricating linear plain bearings are built to last, and they will often out-perform and last longer than a traditional linear ball bearing. Called the “little red bearing” by loyal customers, they have been a popular replacement for failing ball bearings. Simplicity plain bearings will not catastrophically fail.
The difference between a smooth-running drive and constant headaches? The right timing belt and pulley plus a whole lot more. Discover what works, what doesn’t, and put your design skills to the test—engineer your best system yet!

Igus has announced that it is the first supplier to qualify halogen-free chainflex TPE cables for IPA dry cleanroom classes 4 and 5 through the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA). This certification ensures customers in highly automated battery production receive energy supply solutions with a guaranteed service life of up to four years.
Neugart is introducing a new performance class above its existing precision gearboxes with the new PSNpro, PSFNpro and PSBNpro series. These are based on new, innovative gear technologies and the use of new materials in production. The optimized tooth flank quality reduces point load peaks and enables higher torques to be transmitted with the same service life.
