Self Adjust Belt Tensioning Motor Mount

      Disclosed is a mechanism that provides proper timing belt
tension between a printer carriage drive shaft and printer carriage
motor without the use of screws, brackets, springs, take-up pulleys
or adjustments.

      In the figure, motor 7 is mounted into cavity which is part of
molded carriage support frame 8.  Motor 7 is lifted to highest
position 2 along angled surface 1 and drive belt 3 is positioned on
motor pulley 4 and carriage shaft pulley 5.  Gravity pulls motor 7
down vertically and tension in drive belt 3 causes motor 7 to rest
against angled surface 1.  The angle between surface 1 and centerline
6 running between carriage motor and carriage drive shaft is
approximately 100 degrees.  The force exerted by the combination of
the motor 7 weight, the drive belt 3 tension, and the wedging angle
created on surface 1 creates friction force between motor 7 and
surface 1 sufficient to maintain motor position and drive belt
tension during carriage motor 7 starting and stopping.
