I would like to know if the tooth of these gears match with each other. The pairs are:
This, Part No: 4600-008 with this, Part No: 4600-015, and
This, Part No: 4600-030 with this, Part No: 4600-015 .

Gears of the same MOD will run together so 4600-008 & 015 are fine. 4600-030 is MOD 1 so you would need to use a MOD 0.5 work such as 4600-038.

If you need to work out the distance between centres of any two timing pulleys, then this calculator will eliminate the long calculations or trial & error for you.



  Timing Pulley Distance Between Centres Calculator  
  Large Pulley Teeth Number T  
  Small Pulley Teeth Number T  
  Pitch   mm  
  Belt Length   mm  
  Large Pulley PCD   mm  
  Small Pulley PCD   mm  
  Distance Between Centres mm  
  How to use the Pulley Distance Calculator  
  1. Enter the number of teeth on the largest pulley  
  2. Enter the number of teeth on the smallest pulley  
  Note: if 1:1 ratio, enter the same number of teeth in both boxes  
  3. Enter the belt tooth pitch in mm, i.e. T5 is 5mm, T2.5 is 2.5mm  
  4. Enter the belt length in mm  
  The resulting answer is shown in the bottom yellow box. For information, the PCD of the pulleys is also shown in the other yellow boxes.  
  In order to achieve the correct tension, one of the pulleys should be adjustable.
