Having a Ball: The Technology Behind the Ball Drop

The New Year’s Ball Drop wouldn’t be possible without a sophisticated electromechanical system that must operate reliably during the most critical 60 seconds of the year.
April 6, 2023

More than a billion people around the world unite to ring in the New Year, their eyes set upon the glittering New Year’s Ball in Manhattan. Thousands are gathered at Times Square — the famed “Bow Tie” of Midtown — braving the December cold and peering through glasses with numerically shaped frames. Millions more tune in from their various screens at home.
With so much riding on its descent, the Ball, along with the mechanical and electrical systems responsible for its operation, must operate like clockwork.

Precision Coupling Basics—Stiff or Stiff Enough?

When selecting couplings for precise motion applications there are often questions about the most suitable approach for optimizing both performance and economy.
April 6, 2023

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.

The Variation of Servomotor Efficiency in Different Applications

April 6, 2023
Don Labriola

Unlike HVAC applications, servomotors are not normally operated at the same speed or torque for extended periods, thus the overall efficiency of a servomotor is not easily given a single numeric value. The efficiency varies greatly with the application, and thus different applications favor different types of servomotors.

Ball Bearing Inner Ring Fits and Creep (Part 2)

April 6, 2023
Norm Parker

Welcome back to Part 2 of our inner ring and creep discussion. We left off with our creep calculation resulting in a 10.5 µm minimum inner ring fit to avoid creep. For the sake of making clean dimensions, let’s call it 10 µm on the lower end and the upper end is simply whatever your manufacturer can hold.

On the Potential of High-Ratio Planetary Gearboxes for Next-Generation Robotics

April 6, 2023
Marcin Wikło

The earliest example of a gear train dates to at least 2,000 B.C. when Chinese engineers built a chariot that used a complex planetary mechanism made of wooden gears to let a dragon head continuously point south when driven around (Ref. 1). In Greece, a surprisingly advanced Antikythera gearbox mechanism, incorporating at least 37 precisely crafted bronze gears, was built years later, between 205–60 B.C. (Ref. 2).

Bosch Rexroth Introduces Smart Flex Effector Sensor-Based Compensation Module

February 22, 2023

Small component, significant impact: The Smart Flex Effector, a new, sensor-based compensation module from Bosch Rexroth, gives robots and Cartesian linear systems human-like sensitivity and thus offers new opportunities for factory automation. Processes that are difficult to manage can now be automated, optimized and monitored through simple retrofitting. Thanks to a kinematics system that works independently in six degrees of freedom, the tactile device with sensitive touch precisely records the position of the work piece and passes the information to the robot control unit for active compensation purposes.
