IMS Standard Gearbox Typical Design Features

• Designed in accordance with CMAA 70

• Parallel shaft reducer designed specifically for use in hoist and crane applications

• Housing is horizontally split, steel fabricated, stress-relieved, machined, foot mounted with over‐sized inspection covers

• Shafting is through hardened alloy steel

• All helical gearing using normal diametral pitch sizes, full fillet tooth roots, 25 degree pressure angle, made from through hardened alloy steel

• Self-aligning, double-row spherical roller bearings

• Ductile iron bearing capsules that encapsulate the bearing

• Taconite style seals (double seals) on input and output running against a carburized and ground seal sleeve

• Standard lubrication is ISO VG320, special performance lubrication is synthetic

• All IMS reducers come equipped with site glasses, drain valves, and breathers

Rebuild and Redesign Capabilities

• In house engineering with many years of gear design experience

• Active members of the American Gear Manufacturer’s Association (AGMA), including involvement with various AGMA technical committees

• Services available include gearing related failure analysis, inspection, capacity evaluations, and upgrade studies

• Experience with helical, spur, worm, bevel gearing, housing and shaft design, bearing selection

• Old gearboxes can be rebuilt to match the existing design using a combination of existing components and new components

• Old gearboxes can be rebuilt/redesigned using an existing housing and replacing all old gearing with newly designed and upgraded gearing, shafting, and bearings

• Old gearboxes can be completely replaced with a drop-in unit that typically includes a newly designed set of gears, shafts, and bearings that improves the gearboxes overall capacity
