2.1 Horizontal
shaft parts
Friction
clutch is installed between motor and horizontal shaft to connect them.
The
horizontal shah is supported at two points by bearing housing (3) and bearing houseing (4)
with built-in ball bearings and spiral gear is installed between them. Bearing
housing (3) and (4) are
provided with oil seals, respectively, to prevent leakage of gear oil.
A
groove has been cut at the pump side end of horizontal shaft so that the safety
joint may enter.
2.2 Vertical
shaft parts
The
vertical shaft is supported by upper and lower bearing parts and a pinion is provided
between them.
The
upper bearing parts is provided with flat spring and the lower bearing parts
with lower spring so as to absorb vibration in vertical direction. Further. the
upper bearing parts is supported by upper springs at 6 points in a radial
direction for absorption of vibration in horizontal direction.
2.3 Brake
The
brake is so constructed that the brake is applied by causing brake lining to be
pressed against the outside of friction pulley with a spring.
Normally
it is desirable to stop without using brake, but only when prompt stopping is desired
in case of emergency or for repair and inspection, brake can be applied.

2.4 Friction
clutch
The
friction clutch is used to effect slow starting and acceleration so as to
prevent motor overload. The motor shah is equipped with friction block and
friction boss and the horizontal shaft, with friction pul!ey.
After
start-up, the motor attains its rated rotation instantly, friction block lining
is pressed under centrifugal force against the inside of friction pulley, slip
occurs between friction pulley and lining, and driving force is transmitted to
the friction pulley (horizontal shaft side).
The
bowl is so designed that normally it attains its rated rotation in about 5 to 10
minutes.
