Torsional Rigidity is the amount of torque (twisting) that a radial shaft can take during rotation. You can envision torque as the twisting force created when wringing out a washcloth—each hand wrings in the opposite direction, just as a structural member under rotation along a longitudinal axis will tend to twist in opposite directions. As […]

Choosing a Falk gearbox is no simple task. Dozens of variables must be taken into consideration. A single incorrect calculation can cause costly damage, particularly in the case of thermal horsepower. Thermal horsepower is the actual horsepower (without the service factor) that a drive is able to convey constantly for three or more hours without […]

Gear heads and gear engineers both recognize stall speed as a critical figure for torque converters. In automobiles, marine drives, and high shock load industrial transmissions, torque converters (specialized fluid couplings) allow variable speed operation as well as sudden starts and stops. Prior to the invention of fluid couplings in 1905, clutches were required to […]

Proper alignment of Falk gear couplings optimizes power transmissions while maximizing machine runtime. In contrast, poor alignment causes excess friction, limits efficiency, and decreases the lifespan of gearbox components. When machines are properly aligned, axes of rotation are collinear at the point of power transfer. Typically, this means that the rotation axes of the motor […]

Mixer drives are amazing machines. Without them, many industries wouldn’t exist. From pulp and paper mills, to concrete mixing, to food manufacturing and many other trades, mixer drives are crucial for all steady, extended stirring operations. Mixers are also used in pharmaceutical manufacturing, mining, wastewater treatment, power generation, and chemical processing. In today’s post, we’re […]

The gear may seem like a simple, unimportant object, but it drastically changed the course of human history. Gears are simple machines that transmit energy from one part to another. On a bicycle, for instance, gears help transmit energy from the pedals to the gears. (The chain is involved in this transfer as well.) From […]

Here at Mar-Dustrial, one of our mottos is: You can’t go wrong with a Falk coupling. Truly, these ingeniously designed couplings offer countless benefits and are available in a variety of configurations to suit virtually any application or budget. Still, there are plenty of coupling situations that may require some finesse, even if you’ve got […]

Mixer drives are the workhorses of the pulp and paper industry. To provide an industrial mixer with massive torque on a continuous basis – and in a harsh chemical environment – requires a drive with more brawn than your average gear reducer. And while sufficient torque output is, of course, a critical factor in selecting […]

Even the most hardy parallel shaft reducers will eventually need some TLC, given the punishing conditions under which gear drives typically operate. By catching and addressing problems quickly, however, facility maintenance crews can minimize damage, downtime and repair costs. If you notice any of the following issues with a parallel shaft reducer, swift action is […]

There are a number of factors that influence Falk F coupling selection. The first step, of course, is to calculate your torque requirements – grid-style F couplings are designed to handle the most torque of any coupling type. The next rating to consider is service factor. A coupling’s service factor is based on the estimated […]
