‘SMART-G’ is a cyber-physical system that allows the monitoring and diagnosis in-situ of the transmission components allowing us to carry out:
Continuous monitoring of gearbox status.
Diagnosis of possible failure modes that may occur.
Analysis of the evolution of their status.
Data transmission to other upper layer monitoring systems via MQTT.
Direct communication with the system that controls the reducer through industrial field buses (EtherCat, Profinet, Powerlink, etc …)
Storage of collected data.
‘SMART -G’ On Planetary Grinder for Sugar Mill
Steel industry
Coiler
Sheet cutting line
Starting Point
The equipment lacked construction plans.
Our technical service used a scheduled
shutdown and a short intervention time to
perform multiple in-situ measurements for
reengineering.
Result
Complete reengineering of all gears for
gearbox power enhancement, achieving
better performance of the cutting line.
Design and manufacturing of all gears at
GUIBE. Gearbox disassembly, housing
repair, supply of bearings, seals, and
other commercial elements. Chevron and
gear adjustments, contact and clearance
checks, mechanical assembly, and
testing on the test bench.
Using a scheduled shutdown, installation
and commissioning of the refurbished
gearbox in minimal intervention time.

Finishing line
Starting Point
Response to an urgent repair need for the
immediate implementation of the solution
GUIBE despliega una reparación en dos
fases:
1) Reparación provisional urgente paramantener la producción en marcha.
2) Reparación definitiva haciendo uso de
una parada programada.
Result
Repair is divided into two phases: urgent
repair with provisional gears (no heat
treatment) to avoid production stoppage.
Final repair during scheduled shutdown to
replace provisional gears with cemented
final gears.
GUIBE manufactured all gears in F125
steel and cemented, cleaned internal
piping, and measured housing with FARO.
Gearbox assembly and adjustments,
clearance and contact checks, and testing
on GUIBE’s test bench.
Paper industry
Pulper
Starting Point
Equipment with recurring problems without
apparent causes. GUIBE identified the
issue through technical analysis and
provided advice and the best technical
solution.
Gearbox in a hard-to-access location.
GUIBE proposed and implemented
lubrication system improvements and
developed a system to monitor critical
parameters and minimize interventions.
Result
Disassembly, cleaning, inspection, and
inspection report with improvement
proposals: suitable lubrication system for
application conditions.
Housing machining and verification with
FARO technology, manufacturing and
replacement of worn gears, bearings, and
seals.
Implementation of proposed
improvements. Design changes solved
the original problem.
Gearbox assembly and adjustments,
testing on the test bench, and exterior painting
Paper industry
Planetary gearbox
Paper press
Starting Point
No construction plans for the gearbox.
Gearbox was discontinued by original
manufacturer. Equipment with prolonged
and recurring issues and repeated gear
wear.
GUIBE performed engineering, gear and
carrier measurements. After assembling
the first repaired gearbox, GUIBE detected
vibrations and metal particles in the
lubrication system.
GUIBE conducted vibration analysis and
application study, identifying a mounting
fault in the press.
Result
Due to lack of documentation, GUIBE
performed thorough inspections to
determine missing and reusable parts.
Measurement of parts and carriers in 3D
machines, reengineering of existing
gears, design improvements, and carrier
bushing after detecting deviations.
Assembly, adjustments, testing on test
bench, assistance, and in-situ vibration
analysis.
Rubber industry
Tandem duo
Rubber mixer
Starting Point
Preventive maintenance on gearbox and
replacement of all worn elements in noisy
equipment.
GUIBE performed thorough gearbox
inspection (housing measurement,
magnetic particle inspection, contact and
clearance checks) and proposed measures
to restore optimal condition.
Result
Disassembly, cleaning, gearbox
inspection, housing measurement with
FARO technology, magnetic particle
inspection on gears.
Gear manufacturing, bearing and seal
replacement, reuse of critical elements,
gear tooth grinding, and replacement of
piping and flow meters.
Assembly and adjustments, contact and
clearance checks, testing on test bench,
gearbox painting, and delivery of quality
documentation/repair report
