Available with operating speeds to
80,000 RPM, Cotta high speed
transmissions are used extensively in Research and Development
testing as well as production testing of aircraft components
such as generators, CSD's, and pumps.
as both speed
increasers and speed decreasers, Cotta high speed
transmissions are also used in a full range of non-aviation
applications ranging from magnetic levitation trains to
Although each model is highly specialized, the wide range of
existing high speed designs is likely to provide a suitable
transmission for most applications, or a candidate which can be
So, whether a standard, modified standard, or a completely new
design, Cotta high speed transmissions will meet your
Cotta high speeds fall into several basic designs. Our
transmission come with either single or dual outputs. Each type
is available with either one stage gear trains with ratios to
about 1:7, or dual stage gear trains with ratios up to 1:22.
Higher ratios are available in planetary designs or via multiple
A hybrid of these transmission is the
coaxial unit. The co-ax has
test heads at both ends of the output shaft which is hollow.
This transmission is designed to test both a CSD and generator
simultaneously by mounting one at each end of the hollow output
shaft and connecting the two by means of a quill shaft through
the hollow shaft.
Cotta flex drives
are an "add on" transmission. Flex drives come in ratios to
just over 1:3 and are installed on the output of existing
transmission to multiply the output speed. The output of the
Flex drive replicates the output of the base transmission.

Cotta is now offering a special purpose transmission for use
primarily in aircraft high speed component test stands. The
although very compact, features a nominal capacity of 200 HP and
over speed ratios up
to 5.5. The SN2105 is a candidate for the most
cost effective true high speed transmission on the market. To
