Romax Hosts BGA Gear Noise And Transmission Measurement Course
October 10, 2017
The BGA’s Gear Noise and Transmission Measurement course was once again held at the Romax Technology Center, in Nottingham, on September 20.
The course was hosted by Dr. Michael Platten, Romax Technology’s resident expert in dynamics and NVH, and examined the basic causes of gear noise and the path from initial gear design and manufacturing errors to the final noise generation.
To begin the program, an introduction was given to define transmission error and the sources of gear noise. Subsequently, gear design for low noise was examined in more depth, including transmission error in spur, helical, and planetary gears, and the effect of misalignment on tooth contact. Afterward, noise signals, such as tooth passing frequencies, run out, and sidebands were considered. Finally, practical aspects of noise measurement and the diagnosis of the cause or source of the noise were explored.
The overall aim of the course was for attendees to be able to differentiate between gear noise problems and noise generated from other sources, and to identify remedial action required to alleviate the problem.
Feedback from attendees was positive. “The course provides a good opportunity for people from different sectors of the gear industry to get together and obtain common understanding and appreciation for noise and vibration,” said Platten.
