Aluminum Core Spur Gear Specification

alum spur 1

 

OD 19", 2.50" face, spur gear, AL core

Problem:
Gear weight, heat dissipation

Solution:
Metal core: AL, OD 15"
For weight reduction, heat dissipation, etc.

 

 

alum spur 2OD 8.5", 0.75" face, spur, AL core

Problem:
High torque, extremely low inertia

Solution:
Metal core: AL 7075-T651 for maximum strength and dimensional stability - OD 8"
Finite element analysis to determine wall thickness in AL core
Minimized inertia
Very high torque to mass ratio
