Belt drive v/s gear drive
Belt drive Gear drive
  • Belt drive is a method of transferring rotary motion between two shafts. belt drive includes one pulley on each shaft and one or more continuous belts over the two pulleys.
  • Gears are machine elements used to transmit rotary motion between two shafts, normally with a constant ratio. The pinion is the smallest gear and the larger gear is called the gear wheel.
  • Requires more space compared to gear drive
  • Requires less space compared to belt drive
  • High friction loss compared to gear drive, therefore lower transmission and less efficiency.
  • Low friction loss compared to belt drive, therefore higher transmission and more efficiency.
  • Less safety.
  • Comparably higher safety.
  • Requires high inspection and maintenance, but maintenance cost is relatively cheaper and convenient.
  • Requires less maintenance, but maintenance cost is relatively dearer and cumbersome.
  • Low life expectancy than gear drives.
  • Much greater life expectancy than belt drives.
  • Easy, flexible equipment design, as tolerances are not important.
  • Complicated equipment design, as tolerances are very much important.
  • Isolation from shock and vibration between driver and driven system.
  • No isolation from shock and vibration between driver and driven system.
  • Requires relatively less or no lubrication.
  • Requires regular lubrication.
  • Very quiet in operation.
  • Noisy in operation.
