Crushers are key to mining operations, and parallel shaft reducers are key components of crushers. Ever since mechanical and explosive technology allowed the removal of large rock chunks, mining outfits have been looking for ways to crush ore. Rocks must be broken into similarly sized particles for two main reasons: 1) To ready materials for […]

Like all gear reducers, worm gears are used to increase torque while slowing output speed. However, worm gears are unique in that they include a worm—a cylindrical screw that reduces the gear ratio—that is set at a ninety-degree angle to the worm wheel. Overall, worm gears require less space than spur gears. Let’s review the […]

Concentric shaft reducers, also known as inline gear reducers, are unique in that they facilitate installation over a common centerline between the high-speed input shaft and the low-speed output shaft. Concentric shaft reducers thereby solve space restriction and alignment problems of right angle and parallel shaft reducers. Additional advantages of inline gear reducers include their […]

On the most basic level, a mechanical seal is a device that joins together two objects. An adhesive sealant holding pipes together in a plumbing system would therefore qualify as a mechanical seal. Sealants work by gluing together two objects. Gaskets and cartridge seals, found in power transmission products, operate through compression. Simple o-rings are […]

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 […]

The team at Mar-Dustrial recently revived a 12.5 GRF FALK Gearbox that had been stored outside since its last repair nine years ago. The methods used to prep the unit for storage were only good for one year indoors and six months outdoors, so after nine years outside you can imagine the condition this unit […]

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 […]
