2. Bonfiglioli Transmission Pvt. Ltd.
• About the Company :
Bonfiglioli was established on 16 April 1956 to
put into practice the business ideas of
Clementino Bonfiglioli, who brought to his
new company years of experience in the
design and manufacture of gearboxes for
agricultural machinery and motorcycles
(including legendary names like Ducati, Gilera
and Moto Morini).

3. Founder Of The Company
• Clementino Bonfiglioli :
Clementino Bonfiglioli was born in Bologna in 1928.
He dedicated himself to the study of engineering and
graduated from the “AldiniValeriani” Technical
Institute. He began work as a designer and tester in
leading gearbox companies in Bologna where he very
soon came to appreciate how much growth that
sector would soon enjoy as the result of
developments in industrial automation in the
Bologna area.

4. Brands of the Company
• Bongfiglioli Riduttori: Bonfiglioli Riduttori designs
and produces gear motors and power
transmission components for integration into
applications of all kinds and dimensions.
• Bonfiglioli Trasmital: Bonfiglioli Trasmital
specialises in the production of planetary
gearboxes for mobile machines, from excavators
to road construction machinery, and also
produces gearboxes for wind turbines.

5. • Bonfiglioli Vectron: Bonfiglioli Vectron offers a
wide range of electronic products and
solutions for electrical power control and
conversion, including frequency converters,
photovoltaic inverters, regenerative systems
and servomotors.
• Tecnoingranaggi: The Tecnoingranaggi brand
is dedicated to the production of high
precision, low backlash planetary gear units.

6. Gear-motors & Gearboxes
A complete range of gear-motors,
gearboxes and mechanical speed
variators for light duty industrial
automation applications are produced by
the company.

7. Helical Gear-motors & gearboxes
A comprehensive range of versatile
multipurpose industry in-line, shaft-mounted,
single and multi-stage, high torque helical
gear motors and gearboxes.

8. Bevel Helical Gear Motors &
Gearboxes
Versatile bevel helical gear motors &
gearboxes for high efficiency application and
high torque ratings.

9. Worm Gear Motors
Industry worm gear motors comprehensive
range combining state-of-the-art technology
and price effectiveness.

10. Planetary Gear Motors
Compact, powerful planetary gear
motors for industrial and heavy duty
severe applications.

11. Specific Work
• Purpose:
To understand the process of gear box
selection and subsequent installation with
derailing on preventive maintenance
procedures.

12. Processes Conducted
• Gear box selection – (based on cost,
application)
• Gearbox ordering (internal)
• Gearbox installation and commissioning
• Preventive and pre-emptive maintenance

13. Gearbox Selection Tools
• Online Selection of Gearboxes:
We can select gearboxes online by providing
basic information like ratio required, motor
form, torque required etc. Other factors like
cost, models etc. are decided with the help of
company’s representatives.

14. • Gearbox Selection Tools:
Some companies like Nord, Sew etc. use selection
software like Nord Cad etc. However, Bonfiglioli
currently does not use any such software. This is due
to high variety and range of gearboxes.
• Catalogue of Bonfiglioli:
Bonfiglioli has a very well maintained and
defined catalogue for each range of product
offerings. The data required for selection of
gearbox can be applied to sort out the
required model and same can be discussed
with the Bonfiglioli representatives.

15. Information of AS Series Gearbox
• Torque:
Rated Torque: Torque transmissible through
output shaft, under uniform loading.
Required Torque: Torque corresponding to
application requirements. It must always be
equal to or less than rated torque for the
gearbox under study.
Calculated Torque: torque value to be used
when selecting the gearbox.

16. • Power:
Input Rated Power: the power applicable to
input shaft based on input speed n1 and
corresponding to service factor fs = 1.
• Thermal Capacity: Pt is the power that can be
transmitted through the gear unit, under a
continuous duty and an ambient temperature
of 20C, without resulting into damage of the
inner parts or degradation of the lubricant
properties.

17. • Efficiency: Obtained from the relationship of
output power to input power.
• Gear Ratio: The value for the gear ratio is
referred to with the letter (i) and calculated
through the relationship of the input speed n1
to the output speed n2:
i= n1/n2
The gear ratio is usually a decimal fraction.

18. • Service Factor: This factor is the numeric value
describing reducer service duty. It takes into
consideration, with unavoidable
approximation, daily operating conditions,
load variations and overheads connected with
reducer application.
• Maintenance:
Life lubricated gearboxes do not require any
periodical oil changes. For other types of
gearboxes, the first oil changes must take
place after about 300 hours of operation.

19. Installation of the Gearbox
• Make sure that the gearbox is correctly secured
to avoid vibrations.
• Before being paint coated, the machined surface
and the outer face of the oil seals must be
protected.
• Mating surfaces must be cleaned and treated
with suitable protective products
• For outdoor installation provide adequate guards
in order to protect the drive from rainfalls as well
as direct sun radiation.

20. Gearbox Selection by taking One
Instance
