Pendulum joint, the cost-efficient drive
solution with only one unbalanced motor
If a single vibration motor is built onto an elastic pendulum
joint (e.g. a DK element), the device will carry out a slightly
elliptical oscillation shape (linear movement). The final oscil-
lation motion is dependent on the distance between pendu-
lum axis and motor axis. The pendulum suspension has only
been used on rather smaller feeding devices. The inclination
angle of the motor configuration is approx. 45°.
Suspensions of spiral or coil feeders
Spiral-shaped conveyors are used in processing systems
where bulk goods should stay on the conveying trough in the
smallest possible space for a long period in order to cool
down or dry. Not infrequently, the resulting channel length
can be 25–30 meters in a spiral tower that is only five me-
ters high! With a spiral conveyor supported on ROSTA
Oscillating Mountings Type AB-D, there is no need for ad-
ditional fall-prevention devices such as cable bracings or
securing pipes in the spiral, as is the case for helical spring
supports. If a spring breaks here, the complete spiral tower
tilts – unless it has been secured with cable bracings.
ROSTA AB-D suspensions offer a high isolation effect, clear-
ly defined oscillations up to the topmost spiral and absolute
stability for the spiral tower.
