01 / Platform
From the first component to the complete system.
A gearbox is a system of connected components. Bring geometry, loads and component calculations together, from the first layout to the final review.
Connection review
Review how loads move through the assembly. Check strength, deflection, bearing life, losses and temperature in the same model.
Design review
Inspect the details in specialist tools. Bring inputs, calculation steps and results together in a report for design review.
EVOLUTA / Platform

02 / Capabilities
One workspace. Specialist depth.
Move from the complete gearbox to the component you need to examine. Explore the tools below.
Integrated design
Gearbox design canvas
Arrange the assembly, inspect it in 2D or 3D, and review the connected component calculations.
Draft from a specification
Enter power, speed and ratio to create an initial gear train, bearing selection and layout.
Gears
Gear geometry
Calculate gear dimensions, backlash and inspection dimensions. Inspect the generated tooth profile.
Planetary gear design
Check assembly, interference and profile shift, then inspect the planetary mesh in motion.
Gear rating (ISO 6336)
Evaluate tooth-flank and tooth-root safety using ISO 6336 load factors and allowable stresses.
Cycloidal drives (RV-type) Pre-release
Review RV-type tooth profiles, pin contact stress and crank bearing life.
Bevel gear geometry (ISO 23509 · AGMA 2005)
Compare bevel gear geometry, tooth thickness and tool feasibility with ISO 23509 and AGMA 2005 coefficient conventions.
Shafts & connections
Bolted joints (VDI 2230)
Calculate preload, stress, slip, fatigue and tightening torque through VDI 2230 R0–R13.
Shaft strength (DIN 743)
Evaluate static and fatigue safety with the effects of shoulders, keyways and other notches.
Shaft-hub connection (DIN 7190 · 6892)
Check interference-fit pressure, torque capacity, assembly temperature and parallel-key loading.
Involute splines (DIN 5480)
Review spline geometry, tolerances and torque capacity for shear, wear and bursting.
Bearing life (ISO 281 · ISO 76)
Use catalogue or manual bearing data to calculate rating life, static safety and limiting speed.
System & operation
Oil drain holes Pre-release
Check drain capacity and the oil level needed for the selected holes.
Evoluta LubriPath
Set the nozzle and orifice hole diameters and the pump pressure needed from the oil flow each bearing and gear needs.
Gearbox thermal rating (AGMA ISO 14179-1)
Balance power losses and heat dissipation to estimate operating oil temperature.
NVH analysis
Explore critical speeds and potential resonances on a Campbell diagram.
Shaft balancing (ISO 21940-11)
Calculate permissible residual unbalance and correction values for rotor balancing.
03 / Standards
Recognised methods. Traceable calculations.
Work with ISO, DIN, VDI and AGMA methods across gear rating, shaft strength, bearings, connections and thermal analysis.
Check the calculation basis alongside the results.
Verification combines source comparisons, analytical solutions and checks on fundamental physical relationships.
Source comparisons
Equations and coefficients are compared with the relevant standard clauses.
Analytical checks
Where a closed-form solution is available, numerical results are checked against it.
Physical consistency
Units, limiting cases and expected trends have been verified for physical consistency.
