Gear Design Optimisation
Precision Solutions for Quieter Gears and Enhanced Gearbox Performance
Transmission Dynamics specialises in gear microgeometry optimisation, focusing on minimising Transmission Error (TE) to reduce gear noise and vibration. Transmission Error is a function of gear geometry design (both macro and microgeometry) and is influenced by mesh stiffness, manufacturing errors, gear load and mesh alignment.
Through detailed gear microgeometry analysis under various load conditions and mesh alignments, lead and profile modifications can be optimised to minimise noise characteristics.
Our Gear Analysis
Typical analysis includes investigation of the effects of:
Involute profile modification (tip and root relief and profile crowning)
Lead modification (crowning and end relief)
Misalignment
Gear Load
Manufacturing tolerances
The graph above shows an example of radiated noise for automotive scissor gears, where the flanks of the main gears and bias gear were optimised to achieve significant noise reduction of around 12 decibels across the speed range.
Transmission Dynamics also offers full gear design services, including turnkey solutions for any type of industrial gearboxes.
At Transmission Dynamics, we’re not just shaping gears; we’re optimising the future of industrial technology. Our decades of engineering expertise have empowered numerous companies over nearly 30 years.
With an unwavering dedication to precision, performance, and reliability, we stand as your trusted partner in realising your industrial aspirations.
