Torque Limiter F symbol
Freewheel device - Y system
This device is situated inside the gearbox and
is particularly recommended when gearbox
protection is required in the event of accidental
overloading.
In this system, the final gear is connected to
the gearbox output shaft by means of a friction
assembly.
In some cases, this device can be used for time
adjustment or zero reset on timers.
The standard torque setting is from:
- 1.8 to 2.5 cm.kg for gearbox 81 021 with an
initial breakpoint of 7 cm.kg
- 7 to 10 cm.kg for gearbox 81 033 with an
initial breakpoint of 28 cm.kg
This device, situated inside the gearbox,
enables the output shaft to be rotated by an
external force (manual or mechanical)
independently of the final wheel of the gearbox.
Description
A specifically shaped cam (1) is directly fitted
on the gearbox output shaft. The final wheel (2)
of the gearbox pivots freely on this shaft and
has a housing into which the cam fits (1).
Between the cam and final wheel two rollers
are symmetrically located held in place under
the pressure of two springs(4).
When the geared motor is energized. it causes
the final wheel (2) to rotate which, via the two
rollers (3), in turn drives the output shaft.
If, under external force, the output shaft is
turned in the same direction as the final wheel
but at a higher speed, the two rollers (3)
release the final wheel and the shaft speed
becomes independent of the speed of the final
wheel.
The rollers can be located according to
whether the final wheel is rotating clockwise or
counter-clockwise.
Can be used with gearboxes:
81 021 0 and 81 033 0
