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.
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.

When Australian steelmaker InfraBuild needed two new circuit breakers to provide backup for its main electric arc furnace, ABB had the solution—its VD4-AF vacuum circuit breaker with an innovative servomotor actuation system that delivers more than five times the operations of a standard breaker, supporting greater reliability and safety as well as lower operational costs.
.
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.

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.

Half a million global visitors visit Aiguille du Midi as an access point for skiing in the winter and hiking, rock climbing and paragliding in the spring, summer, and autumn seasons. The mountain—part of the French Alps—boasts the current title of employing “the world’s highest vertical ascent cable car.” This unique transportation takes passengers from 3,396 to 12,605 ft. above the clouds. The planetary gearboxes needed for the cable car operation are provided by CMD Gears.
Atlanta Drive Systems, Inc., Farmingdale, NJ, offers rack and pinion systems, actuators, gearboxes, servo reducers and lubrication systems for many different industries including machine tool, automation, aerospace, woodworking, material handling, robotic, food, packaging, stone and special machinery. PTE recently discussed the company’s lubrication solutions with Peter Alfano, senior applications engineer.
Bearing damage due to electric current in variable frequency drives (VFD) is well understood as a general concept. What is not yet fully developed are the models that better predict when a system is at risk and where we should be looking for early signs of damage.
Closed-loop control systems can handle a wide range of motions with a wide range of loads if the control system and the mechanics of the system are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable but also how to get the desired performance.
Spiroid Gearing delivers precision gearing for advanced mechanical systems, engineered to handle extreme torque and complex motion requirements. With unique right-angle gear solutions, our technology enhances efficiency, reliability, and design flexibility - empowering engineers to push boundaries in aerospace, defense, robotics, and industrial applications where performance and durability are non-negotiable.
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!
