Define the issue and the meaning of inputs
Define the issue
describe changes with speed, load, direction and start-stop operation, including sensor locations/directions. Preserve time waveforms, spectra, units and sampling conditions. A sound video assists description but does not replace measured values.
Gear geometry determines the load path
Bearing positions
input, intermediate and output shafts and gear supports.
Arrangement differences
the deck lists deep-groove balls/cylindrical rollers for spur gears; helical gears add axial loading and use angular-contact balls, tapered or spherical rollers; internal meshes use cylindrical, tapered or spherical rollers.
Engineering focus
radial/axial load directions, locating/floating supports and shaft deflection from meshing.
Provide
gear geometry, ratio, torque, shaft position, support spacing and rotation direction.
Stage-specific wind gearboxes
Bearing positions
carriers, planet gears, low- and high-speed shafts.
Arrangement
single-row tapered carrier bearings, outer-ring-free cylindrical planet supports, and NU cylindrical rollers with paired tapers on shaft positions.
Conditions
low-speed heavy loads coexist with high-speed friction and temperature rise; a single speed/life figure cannot describe the whole gearbox.
Engineering focus
stage-specific load spectra, profiles, axial support, oil supply and housing deflection.
Steel-mill main drives: shocks and torque
Equipment positions
bar, section and plate main reducers and converter tilting drives.
Conditions
high power/torque, shocks and overturning moments with process-dependent loads.
Arrangement
full-complement cylindrical and spherical-roller examples.
Engineering focus
roller contact profiles, friction, precision and housing stiffness, together with installation and maintenance access.
Follow an evidence-based inspection path
Inspection path
correlate gear stages, bearing location, force direction, fastening and lubrication records. Pair each hypothesis with a verifiable observation. Without rolling-element counts and geometry, do not generate designation-specific fault frequencies or generic acceptance thresholds.
Information for a technical enquiry
Equipment and position
machine model, mounting position and complete bearing designation with suffixes. For replacements, include the original arrangement and fit dimensions.
Operating records
bearing speed in rpm, radial and axial loads, shocks and starts/stops. Paper-web and rolling-line speeds are not bearing rotational speeds.
Lubrication and assembly
lubricant grade, oil supply or relubrication records, temperature, mounted clearance or preload, seals and contamination.
Problem and objective
temperature rise, noise, vibration or flaking, timing, photographs and maintenance records, plus the outage window or redesign objective.
Record a practical verification plan
Record drawing/reference versions, original duty, proposed changes, verification methods and results. Separate observations, hypotheses and verified conclusions. Follow equipment procedures; do not exceed operating limits to gather test data.
