Heavy-Duty, Enclosed Gear Assemblies
TRUMBULL MITER GEARS are designed to fulfill the following primary functions:
• To be used as an add-on component to Trumbull Floorstands or Pedestals
• To be mounted directly to valves where a 90 degree change in the input shaft direction is required
• For use as a stand-alone component in a valve operating assembly with rotating elements, such as extension stems, where the installed conditions require one or more 90 degree changes of direction
Housings are cast ductile iron 65-45-12 with a Tnemec N140-1211 two-part epoxy, NSF-61 certified exterior coating. The gears are case hardened steel; the gear shafts and fasteners are 316 stainless steel.
Trumbull Miter Gear Assemblies are provided standard with a recessed grease fitting for easy maintenance and Buna-N O-ring seals on each end adapter.
Trumbull Miter Gears have a recommended maximum torque of 300 ft-lb (406 N-m). For applications with higher torque requirements, please consult Trumbull.
Gear Ratio = 1:1, Input/Output Shaft Diameter = 0.984″.
