Ground Gears
As
commonly seen grinding is most of the time thought in context of quantity
fabrication of premium quality gears as a sort of secondary refining
operation. We tend to forget that grinding is essentially a basic process in
the step towards manufacturing case hardened gears. Moreover, the teeth of
high-precision fine-pitch gears often totally ground from the blanks itself.
Advantages of Ground Gears
The
Ground
Gears offers specific advantages to its users. Some of which are
listed below.
- High Precision
Getting high precision is not a big task for Ground Gears as in the
grinding process there is little removal of material in the final pass.
- Finer Surface Finish
Grinding gives the Gears a surface finish more finer than that obtained
from any other machining process.
- Added Flexibility
It is possible to use hardened steel alloys to be developed into Ground
Gears.
- Minimal Surface Stress
There is minimal residual surface stress in case of Ground Gears.
- Load Carrying Capacity
Ground Gears displays a superior load carrying capacity.
- Minimal Wear and Tear
This reduced wear results in prolonged life for Ground Gears.
Limitations of Ground Gears
Though there are many advantages associated with Ground Gears, but they are
not without any weakness.
- There is a limit to grinding operations and that is to ferrous
metals.
- Hard metals can be grind in a better way than the soft ones.
- In case of helical or worm gears, grinding may not be the right
solution. As it often involves deviations in terms of profile and
removal.
- Gear grinding machinery is not so popular as hobbing machines.
- Grinding involves higher costs as it is a secondary operation.
