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.
|
|
|
- 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.
