 Cotta
engine mounted speed increasers increase the engine speed to the
driven equipment speed allowing both the engine and the load to
operate at ideal speed and efficiency.
Cotta Speed Increasers are are designed for use with the
commercial offerings of major engine manufacturers and are used
extensively in applications where diesel engines replace
electric motors.
Direct mount speed increasers are available with SAE flywheel
housings from #5 to #00, ratios to 1:4, and horsepower capacity
to 2000+.
Flywheel connection options include over center clutches, air
clutches, drive plates, and torsional couplings. The gearboxes
can be used as independent mount by replacing the bell housing
with a mounting bracket.
Many special purpose speed increasers are available. If our
catalog offerings do not meet your needs, ask a Cotta Sales
Engineer about modified standards or special designs.

Note: the
following table contains generalized information. many
features such as
clutch size and bell housing selection affect weight
and installation
dimensions. Ratios differ from engine to anti engine
rotation. Click on an individual model to get more precise

- All dimensions are in inches.
- Bell housing are standard for the model shown. Chart dimension "A"
is base upon that standard. Consult individual spec sheets for
optional bell housing dimensions.
- Standard output shaft location for speed reducers is 12 o'clock to
the input (as shown).
- Cotta speed reducers are designed to be driven clockwise facing
the input shaft.
- Refer to individual spec sheets for speed limitations.
- Speed increasers require rear supports.
Note: in order to specify a speed increaser we will need the following
information:
- Input speed
- ideal output speed
- flywheel housing size
- flywheel connection requirement (clutch, drive plate, torsional
coupling, etc.)
- direction of rotation (engine or anti engine)
- type of driven equipment
