METHOD OF SELECTION
3. Selection of types with input speeds
of 1440 r.p.m. approx.
Knowing the corrected power the output speed and the reduction ratio, you have to consult to the power tables and choose the type of reducer, bearing in mind that the maximum transmissible power of this one being the same or superior to the corrected power.
 
Selection of types with input speeds different from 1440 r.p.m.
The powers given in tables, are only valids for one nominal input speed similar or approximate to the one indicated in them. To choose a type of reducer serie "L", please use the power graphics on pages 2.1.2, 2.1.3 and 2.1.4
 
To choose a type of reducer serie "I", please go on of follows:Only using the table zone of page 1.1.2 corresponding at 1420 r.p.m. mode first the input speed ratio in order to correct the power.
 
Example: Corrected power kW.: 1.1 kW.

Input shaft speed: 567 r.p.m.
Output shaft speed: 150 r.p.m.
Reduction ratio: 3.78/1

..........................Ratio of As table 1420
input speed: ---------------------------------------------- = 2.5
...........................Wished speed 567

Correction of power (only for selection)
1.1 kW. x 2.5 = 2.75 kW.
 
 
The corresponding table does not include 2.75 kW., although it does have those of 1.9 kW. and 3.3 kW. one should therefore pick the speed reducer that corresponds to 3.3 kW. On the corresponding table, for one reduction ratio of 3.78/1 it doesn't appears the power of 2.75 kW., so, you should choose the reducer corresponding for power 4 kW.

Speed reducer selected: TYPE 142
