Drones are tasked with providing state-of-the-art autonomous capabilities, unique movements, automated inspection, urban delivery solutions and advanced military operations. They upgrade agricultural farming technology, provide safety and logistic solutions and report key disaster and engineering mapping. PT components such as motors, controllers, and sensors are an integral part of their core structure.
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.

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.

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.

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.

Motion + Power Technology (MPT) show brings together the gear and power transmission industries for a unique balance of education, new technologies and networking opportunities. The show takes place October 17-19,2023 in Detroit.
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.
As industries adopt more automation, the demand for reliable and efficient pneumatic systems, which power everything from robotic arms to air-powered tools, continues to rise. However, despite their widespread
use, these systems often suffer from hidden inefficiencies. Here, Chris Johnson, managing director at SMB Bearings—Oxfordshire, U.K.) explores how an overlooked component, industrial bearings, can improve the
efficiency of pneumatic technologies.
Curious about the state of robotics and automation? A day or two at Huntington Place in Detroit this spring should clear everything up. Automate 2025 attendees might see robots serving coffee, robots maintaining shop floors, robots building other robots. We have officially crossed the threshold from future possibility to practical application.
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!
