Abstract
The paper analyses the increased noise levels that occurs and reaches 10–18 dB when performing milling work on gear hobbing machines at the machine operator workplace. It deals with the issues of substantiating the choice of noise protection systems in work processing on gear hobbing machines. The calculation is based on theoretical studies of the noise generation process and experimental data, as well as an acoustic calculation performed when designing noise reduction systems. The technological process of gear hobbing and the layout of the hobbing machine's workplace make it possible to reduce noise at the source of its occurrence. The author proposes the design of noise protection systems for machine operators and presents the results of experimental tests of the system effectiveness.
