Spur Gears
Global Gear produces more than 300,000 spur gears annually for a variety of applications, including pump drives, secondary gear trains, and constant/positive speed drives. These gears range from 25 mm to 300 mm in diameter, with widths up to 150 mm and module parameters up to 8. Operating on parallel shafts with the same diametric pitch and pressure angles, spur gears are a very cost effective gear design for many applications.
Helical Gears
Global Gear produces highly engineered helical gears for a variety of applications and can produce gears with up to a 42º helix angle. Typical helix gear applications require higher torque, high pitch line velocities, and low NVH. These applications inlcude hardened and non-hardened diesel engine gear trains, as well as pinion gears, rings and shafts for transmissions and transfer cases.
Transfer case ring gear with shaped internal helical teeth and external hob positioning features.
Helical transmission gear with lubrication slots and internal broached spline.
Shafts
Global Gear produces machined shafts used in applications that provide the interface of power devices to transmissions, axles, and power takeoff (PTO) components. These typically include shafts with internal or external splines with custom-designed engagement features. Global Gear manufactures these in a variety of machining centers with lengths up to 600 mm.
Coupling shaft with external hobbing and internal spline used in agricultural applications.
Precision machined transmission shaft having ground helical gear teeth, internal spline coupling, clutch engagement and lubrication features.
Pulleys & Couplings
Global Gear manufactures pulleys from steel and cast iron that typically include bushings or bearings, as well as couplings that are produced from steel materials incorporating rubber bushings for load distribution and absorption. Global Gear is experienced in a variety of surface treatments to meet the specific customer requirements for these products
Typical V belt pulley with bearings assembled for auxiliary component drives.
Engine coupling with steel-inserted vibration dampening grommets.
Precision Machining
Global Gear utilizes a variety of precision machining and automation equipment to produce complex designs for applications requiring exacting tolerances measured in microns. These products range from low volume shafts to high volume air bag components. The specific technologies employed and quality control plans utilized are developed to meet these tolerances.
