Executive Summary:
The skewed roller clutch has become a subject of interest in recent years
due new ideas in its many possible uses. Taking the place of common clutch
disks, the skewed roller claims many advantages over conventional braking
mechanisms, such as better friction coefficient stability, lower wear
rate, and higher power absorption capabilities. For this reason, the commercial
aircraft industry has endeavored to learn more about the skewed roller
clutch.

| By taking
a two-phased approach, our team will demonstrate how roller geometry, skew
angle, and contact pressure contribute to performance, which will ultimately
be characterized by the coefficient of friction. Researching previous analysis
preformed on clutches and brakes as well as on roller thrust bearings, a
detailed theoretical analysis will be available to generate relationships
between variables and coefficient of friction. This new analysis will be
comprised of systems of equations solved via MathCAD, enabling efficient
calculations and dimensionless parameter results. With a theoretical analysis
in hand, a test fixture built to measure output torque will be used to verify
the theoretical analysis by measuring static parameters. Dynamic parameters
will not be able to be investigated due to insufficient time and funds.
However, consideration will be given to future testing which will include
dynamic parameters. The test fixture will be setup to measure torque. With
the conclusion of testing, a comparison of test data to theoretical data
will be conducted to verify or discredit previous assumptions and analysis.
