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.

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.

Understanding the Dynamic Influences of Gear Oils and Radial Shaft Seals

February 1, 2018

Sustainability is becoming one of the most important aspects within the power transmission business. Users demand low-maintenance drive systems with as little disruption as possible, and expect lifetimes of more than 10,000 hours. Approximately 40 percent of long-term gearbox leakages can be traced back to poor interaction between the radial shaft seal (RSS) and the lubricant. Thus, it becomes essential to analyze the tribological system as a whole, which includes the gear oil, seal grease (if required), elastomer material and design, and the shaft.
