Falk High Thermal Capacity Drives

Type YB

Type YB Right Angel Shaft

Since 1897, Rexnord has specialized in the research, design, and construction know-how built into the rugged, dependable Falk gear drives. These precision, through hardened helical right angle Type YB drives are based on earlier successful models. To maintain that reputation, and to keep a step ahead of today's increased industrial requirements, our 20 standard sizes now transmit higher capacity (up to 3727 hp and 2,684,000 lb.-in. output torque) without an increase in external dimensions. This means we've improved the strength and performance of gears, shafts and bearings. To hold them in exact alignment day after day and year after year, extra strong, accurately machined housings are provided. In addition, our Drive One and Type AB line of horizontal right angle drives offer state-of-the-art surface hardened helical and bevel gearing.

High Capacity Bearings

Roller bearings have been designed to exceed minimum AGMA specifications for the most severe loading conditions with minimum friction and easy starting. You can count on bearing life well in excess of industry standards for most applications. Precise selection methods are based on data obtained from actual test of the drives.

Heavy Duty Shafting

Large shaft diameters are designed to maintain accurate support and alignment of gearing under the most adverse loading conditions, and provide optimum external thrust and overhung load capacities. Double ended low speed shaft extensions can be supplied at no extra charge only when specified on the order.

No-Leak Seals

Keep Oil In - The Falk "Magnum™" seal keeps oil in the drive and keeps dirt out. The inner cage has close fitting clearances between the shaft and bearing race which prevent oil from leaving the drive. The oil drain back ensures an effective seal by returning any oil that gets beyond the bush seal, back into the drive. Since there are no moving parts, this throttling bush seal arrangement will last as long as the drive if properly maintained.

Keep Dirt Out

An outer cover assembly, when filled with grease, prevents the ingress of foreign particles by trapping them before they enter the drive. Periodically, introducing fresh grease through the fitting in the cover, will purge contaminants.

AirMax® Breather

Unique Moisture & Particulate Protection for Enclosed Gear Drives (Optional Accessory).

GMAX 6000™

Horsepower, Heat, Moisture, and abrasive contamination are constantly working to break down your gear drive lubricant. GMax 6000 is designed to provide superior wear protection in the most demanding gear drive applications. GMax 6000 is a Polyalkylene Glycol based lubricant or PAG. PAG synthetics have exemplary lubricating properties over traditional Polyalphaolefin or PAO Synthetics and mineral oils. The viscosity index of PAG lubricants is double that of PAO lubricants. This means that a PAG will perform much better over the range of operating temperatures experienced by an industrial gear drive.

Rugged Housings

All steel housings provide maximum strength and rigidity. Accurate machining ensures precise alignment of all revolving elements necessary to maintain engineering and performance advantages. The split housing design with large inspection cover makes maintenance easy. Surfaces are smooth, flat and easy to clean. The exterior is coated with the highest quality zinc chromate primer. The finish coat is sprayed with acid and alkali resistant enamel.

Precision Gearing

From the special alloy steel poured in our own foundry through the final finishing operation, constant quality control is maintained at each manufacturing step. Deep tooth form with high pressure angle allows greater surface durability, greater resistance to abrasion and breaking, and more load carrying capacity. High helical gear efficiency of 98 ˝% per gear mesh remains constant throughout the entire life of the gears.

Positive Lubrication

Continuous splash system is positive and thorough, and provides higher thermal ratings through the use of a large oil reservoir. Oil is carried to the working faces of the gear teeth through the oil troughs in the reservoir, than passes through the bearings. The system is basically simple, maintenance free and highly effective. Oil levels are easily checked with standard dipstick.

Type Y

Type Y Parallel Shaft

Since 1897, Rexnord has specialized in the research, design, and construction know-how built into the rugged, dependable Falk gear drives. These precision, through hardened parallel shaft drives are based on earlier models. To maintain that reputation, and to keep a step ahead of today's increased industrial requirements, our 23 standard sizes of Type Y transmit higher capacity (up to 10,000 hp and 2.8 million lb.-in. output torque) without an increase in external dimensions. This means we've improved the strength and performance of gears, shafts and bearings. To hold them in exact alignment day after day and year after year, extra strong, accurately machined housings are provided. In addition, our Drive One and Type A line of parallel shaft drives offer state-of-the-art protuberance hobbed, case-carburized and finish ground gearing.
