Modulo function
Position Detection and Positioning
Chain conveyor
with carrier
Step 1: Defining the output unit
Now, the previous example shall be extended:
A gear wheel is mounted to the gear unit that drives a chain. There are 35 chain links
between each carrier.
Step 2: Determining the SHELL parameters
Number of teeth of the additional gear chain sprocket: Z
AG
1 = 5
Carrier spacing in chain links: Z
AG
2 = 36
i additional gear = 5/36
