9. GEAR TRANSMISSION
 Hero Motors is manufacturing top-
notch gears and transmission
systems in its world-class plants with
the most modern machinery . The
company has been successfully
catering to the needs of its
esteemed customers like Rotax,
BMW etc.

10. PRODUCTION OF GEARS :
1. GEAR CUTTING :
 The material between conjugate tooth
is removed by machining. The
material removal is complete in each
instance as a result one by one tooth
form is produced.
 Gear cutting method follows the LAW
OF MACHINING.
1) GEAR MILLING
2. GEAR GENERATION
 Whereas in Generation all the
locations where the material should
be machined are machined
simultaneously. As a result in an
intermediate machining time all the
tooth are partially formed. The
generation may be along the width or
along the depth
 Gear generation follows the LAW Of
GEAR MESHING along with METAL
CUTTING PRINCIPLE.
1) GEAR SHAPING
2) GEAR HOBBING

11. GEAR MILLING : set the cutter rotation. Feed the job against the
cutter upto required depth. Feed the indexing attachment with the
job upto required distance.
 DRAWBACKS : The accuracy of gear is not very good.
 sources of erros : Non uniform spacing and Error in profile.

12. GEAR SHAPING : Reciprocating motion of cutter(rack or circular),
Meshing motion of cutter and blank and feed motion of the cutter are
provided simultaneously.
Rack cutters are cheaper but due to frequent resetting is uneconomical, so
Circular cutters are preferred. This method is known as Universal Gear
generation method as all type of gears spur and helical (also internal and
external) of all industrial size can be made.

13. GEAR HOBBING : Motion of cutter and blank are matching motion of
Worm and Worm wheel. Feeding of the job is continued until whole
length of gearing is coverd.
For each module different cutters are available.
Cutter is costly due to manufacturing
difficulties. But due to rapidness of
cutting and better tool life, in mass
production cost becomes much
lesser compare to other methods.
It is not possible to generate internal
gears by hobbing.

14. HEAT TREATMENT :
 PRE WASHING
 PRE HEATING (at 450 C, 2hrs) CARBURISING (905 C-910 C, %C=0.95, 85mins)
DIFFUSION (905 C, %C=0.70, 40mins)
 CASE HARDENING HARDENING (840 C, %C=0.65, 30mins)
QUENCHING (oil temp=110 C, 10mins)
 POST WASHING (50mins)
 TEMPERING (at 180 C, 2hrs)
 SAMPLE INSPECTION
 SHOT BLASTING

15. PERFORMANCE OF GEARS : It depends on accuracy of cut and
the surface property i.e. Hardness. As all the machining to mfg the gear is
done on unhardened blank, hardening is necessary which likely to induce
certain geometric errors. Gear shaving and Gear burnishing may be
employed followed by Grinding.
GEAR SHAVING(BROACHING)
 Gear shaving is the method to remove
the minute amount of unwanted
material from the gear prior to heat
treatment.
GEAR BURNISHING(METAL FORMING)
 Gear burnishing works on the principle of
Cold Working(metal forming) which
simultaneously gives the correctness of the
profile as well as surface hardening.
