Step 1: Types of Timing Belts
Step 2: Select Pitch
Let's work with 3MM (GT2) Pitch and select belt and pulleys. I use this Center Distance Designer for my design. click this link.
Ratio 2:1 and center distance 6 inch or 152.4 mm.
Small pulley that goes on the AC/DC motor is 16 tooth.
Large pulley that goes on my work output is 32 tooth.
Plug in the data into the CD designer to find the belt length. As you see 130 grooves or teeth recommended.
Step 3: Selecting Pulley
16 tooth SDP A 6A53M016DF0606 and 32 tooth SDP # A 6A53M032DF0606.
Step 4: Pulley Drawing
Step 5: Belt Selecting
Step 6: Selecting Shaft
Note: Both pulleys bore tolerance +.025/-.000
AC/DC motor must have 6.00 mm shaft.
Shaft selected SDP A 7X 1M060100 6.00 mm bore and 100 mm length
shaft is 5.996 mm and pulley bore is 6.025 mm, both will work fine.
Step 7: Design Assembly
List of Components on hand:
AC/DC power source (Adapter or Batteries)
Mounting Plate or Base
Stainless steel shaft
Drive pulley or small pulley
Driven Pulley or larger pulley
Test anything on the work output end, where the large pulley is located.
