Criteria for choice |
|
|
|
Choosing a TAR 270 or a TAR 160 depends on the following factors:
- the conditions of use (see following table),
- anticlockwise direction of rotation, only possible with TAR
270,
- the need to work with just 3 stations, only possible with TAR
270. |

Calculation of Moment of Inertia |
|
|
|
The total moment of inertia It [kgm²]= Ip + Ic is obtained by the sum of the moments of inertia of
the top plate and of the load handled, which can be calculated
with the formulas given hereinafter.
|
|
|
|
Ip = Mp • D²/8 moment of inertia of the top plate
Mp [Kg] = top plate mass
D [mm] = top plate diameter
Ip [kgm²] = M • D²/8.000.000 |
|
|
|
|
|
Ip = Mc • b² moment of inertia of load
|
|
|
distributed on circular ring
|
Mc [Kg] = load mass
b [mm] = load radius
Ic [kgm²] = M • b²/1.000.000 |
|

|
Speed of rotation |
|
|
|
The transportation times that can be reached in relation to the
moment of inertia are shown in the following graphs.
