Belt vs. Chain drive
Belt vs. Chain drive
(OP)
I am currently fitting a horizontal blender with a 60HP motor and gearbox. The output of the gearbox is 120 RPM and the blender will be approx. 25 RPM. I have 2 options to drive the blender:
Option 1: Sprockets (39.4" dia (60 teeth) & 9.3" dia (13 teeth)) and Chain (#160)
Option 2: Pulley (39.3" dia (224 teeth) & 8.8" dia. (50 teeth) and HTD belt (125 mm wide)
Considering this to be severe duty operation, what are the advantages and disadvantages of one option vs. the other in terms of application and long term maintenance? I am not very experienced in this field so any insight would be greatly appreciated.

RE: Belt vs. Chain drive
Belt drives- advantages: no lubrication required;minimal maintenance;sudden shocks dampened;quiet;smooth;sheaves(pulleys) generally less expensive & wear over long periods
-disadvantages:slippage can occur;wear reduces tension;severe environment can damage belts
Chain drives: advantages:no slippage;no stretch;long operating life expectancy( assuming proper lubrication);operate in hotile environments;long shelf life ( metal won't deteriorate)
-disdvantages: noisier (generally);can elongate due to wear of chain/teeth;sprockets need replacing when chain worn
If its severe duty then I assume its not a 'food'grade application & lubrication not an issue
Remember that either system needs adequate guarding - In my experience a problem on the driven side in a belt system will burn the belts, but in a chain drive, if the chain doesn't braek the key & shaft are damaged
