multi disc brakes for universal input
12. multi disc brakes:
D
A
Our gear units can be supplied with hydraulically released negative multidisc
brakes.
Y A1
Negative brakes are held on by a series of oil springs pressing together
alternate fixed and rotating plates. This means they work as a „negative“
brake and are intended for parking or emergency stopping only. Normal stopping of the machine should be done by the hydraulic system.
øP
The performances, with +/- 10 % accuracy margings, are always calculated
without back pressure; otherwise the braking tourque is reduced as a percentage of the ratio back pressure/minimum opening pressure.
When carring out the selection, the following two conditions must be taken
into account:
1) Braking torque x ieff > required output torque;
2) Braking torque x ieff < 1,1 ∙ T2max
C
We remind you that high rotation speed, or extended running with vertical
axis , can generate considerable temperature increases; in such cases, or
when braking of high interial loads is required, please apply to tecnical-office
staff for advice.
B
For lubrication we recommend to use mineral oils, heat and aging resistant,
having viscosity ISO VG 32 and viscosity index at least 95; hydraulic oils are usually suitable.
