BMG Drives has been appointed to exclusively represent the Falk V-Class range of industrial gear units in sub-Saharan Africa. These drives reflect the latest innovations in gear unit design in the most demanding bulk materials handling applications.
“The conveying of bulk materials almost always takes place in aggressive environments and remote locations. Dust, heat, humidity and corrosive elements, coupled with shock loads, high starting inertias, high output speeds and external static loads, create a combination of extreme operating conditions which challenge the dependability of conveyor drives,” says Dave Russell, BMG’s technical director. “BMG’s confidence in the reliability and performance of this range is evident in a three-year, heavy-duty warranty.”
Falk V-Class gear drives deliver higher output torque densities than conventional units, superior thermal performance, enhanced lubrication and optimised bearing life. They are designed with adjustable installation footprints to simplify swap out of other brands and a horizontally split housing for ease of in situ maintenance.
This range, with 29 size increments, takes torque ratings up to 341 000 Nm, enabling V-Class to meet application requirements more precisely. Nickel chrome molybdenum steel helical gears are cut to a 25° pressure angle to maximise shock load sustainability. The case hardened and ground teeth are produced to AGMA 12 high quality standard to maximise strength and durability through pitting resistance. All gearing, including the precision ground spiral bevels, have optimised geometry to ensure full contact under load.
Oil feed passages in the housing ensure positive bearing lubrication and enhance the cooling effect achieved by cooling fins cast into the housing. These features, together with axial cooling fans, maintain the lubricant at tolerable operating temperatures. This ensures effective boundary layer lubrication between mating gear teeth and bearing raceways.
The housing design also keeps lubricating oil present at the bearings at all times, including cold starting. Conventional gear unit designs, where bearings start up without lubricant, have the disadvantage of high wear rates and reduced bearing life. The horizontally split housing of V-Class allows easy assembly and disassembly for maintenance of bearings and gearing, without having to remove the reducer from its location. Removable and customisable feet facilitate easy interchangeability of other gear units.
Reliable components, which ensure long-term operation are standard. These include magnum seals with a no-leak design. A purgeable grease chamber and contact seal eliminate oil leaks and prevent the ingress of dirt. For extreme conditions of ambient operating temperature environments, the patented DuraPlate self-contained cooling system is available as an option. This system requires no external power or water supply, yet has the equivalent effect of an airblast external heat exchanger or water-fed oil sump cooling coil.
BMG is able to enhance the drive system with a full range of mounting fabrications. These include traditional foot mounted baseplates, swing base designs, alignment-free lantern versions, top motor mount, motor bracket and integrated IEC motor flange designs. These arrangements can be supplied with a comprehensive range of electric motors and fluid, flexible and rigid coupling drive components.
The Falk V-Class range has been tested for endurance, durability and thermal performance in extreme conditions and high loads. Results show these gear drives can outperform any gear drive available and efficiently withstand operation in any environment, especially in dirty, dusty and hot application environments commonly found where bulk materials handling conveyors are employed.
BMG’s specialist technical resources division, which provides and supports total process solutions across the entire BMG product range, also encompasses a national field services facility. This professional service is available to install and commission Falk V-Class drives and other equipment in BMG’s portfolio.
This service, which mobilises specialist skills to support South African operating plant, complements a company’s own maintenance capability to ensure the highest level of plant reliability. Specialist services include installation, adjustment and maintenance of components, shaft and pulley alignment, balancing, oil sampling and analysis and critical equipment inspections and lubrication schedules.
Other units in the range include Nord geared motors and gear drive solutions, IE1 and IE2 high efficiency Synergy electric motors, Danfoss variable speed drives and Varvel worm and helical geared motors. BMG Drives also distributes Fenner shaft mounted drives, Sumitomo cycloidal geared motors for heavy shock loads, Dinamic Oil planetary gear units and Zollern Dorstener customised drives.
