SUMMARY
20+
years experience in power transmission gears, fiber reinforced composite
plastics, engineering software development, mechanical design in aerospace and
automotive. Expert in 3-dimentional CAD gear modeling. Promoter of cutting spiral bevel gears on 5-axis CNC machines as an alternative to Gleason and Klingelnberg machines. Inventor
of Direct Digital Simulation
method for gear design and manufacturing. 15 years experience in
engineering software development related to tooth contact analyses and gear
manufacturing for spiral bevel,
hypoid, globoid, worm face, crown face, helical gears and variable ratio rack
and pinion drive. Experience includes: 15 years in composite gear
design and fabrication, 7 years in helicopter transmissions, 8 years in
automotive power trains and activators, 5 years in marine drives. Familiar with
gear manufacturing: hobbing, shaving, honning, cutting, grinding, CNC dressing, tooth surface
modification, crowning, shaping, forging, tip and root relief, face milling
(GLEASON), face hobbing (OERLIKON), palloid (KLINGELNBERG), not involute
tooth, Wildhaver-Novikov tooth form, whirling, CBN
grinding, CMM inspection, gear machine summary calculation, heat treatment.
Design experience with: Pro/Engineer, AutoCAD and Mechanical Desktop. Familiar
with composite manufacturing: filament winding, resin transfer, injection
molding, vacuum molding, spray applications with chopped fibers, hand laminate,
bounding between metal and composite plastic, structural carbon and glass
fibers. Software development experience in Windows environment with: FORTRAN,
Visual Basic, C, Java, 3-d Studio Max, OpenGL, FEA, CFD, NURBS, IGES, HTML.
Have an extended experience with design and manufacturing of light weight and
non corrosive power transmission gears incorporated with composite plastic
structural elements for boats, helicopters, airplanes, automobiles
and racing vehicles. Proposed and
developed practical solutions for improving driving efficiency of gears for
increasing of fuel economy and reducing noise of cars and trucks, increasing
power to weight ratio on helicopter transmissions and activators, and
increasing efficiency of marine propulsion systems. Proposed new solutions for
mechanical mating components with different surface geometry for lower friction
and improved lubrication. Designed novel cutting, grinding, shaving,
forging and molding tools. Have numerous engineering awards, inventions and
publications.
