- 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
