How to reduce the gear motor noise.
There are many methods of noise reduction for dc gear motor, which are divided into two categories: one is to actively reduce noise from the gear motor design, which enables the product to have low noise performance at the beginning of its formation. The product is easier to meet the lower noise requirements. The other type is that the product has been formed, and remedial measures are passively taken to reduce noise on the product, so that the product meets the predetermined low-noise performance requirements; such as improving the processing accuracy and careful assembly on the product, so that the noise can be reduced to a certain extent. Effect; but the method of improving gear accuracy and assembly accuracy has to pay a great economic price, and the improvement of accuracy also has certain limits and cannot be endless. Through the analysis of gear transmission noise and the analysis of the international research situation, it is emphasized that more damping materials should be used in the gear and installation. Pay attention to the gear design, measurement, inspection and good box design to make the gear transmission emit less noise. Method. The study of the influence of the external damping layer on noise, especially the noise reduction and remediation of the equipment that has been produced, has the advantages of simplicity and convenience, low economic cost, no need to make any changes to the equipment structure, significant noise reduction effect, and high cost performance. The improvement of equipment can be comprehensively controlled with other noise reduction measures. In this way, under the current market economy conditions, it is a better method that not only enhances product market competitiveness, but also improves performance and economic benefits. In this paper, through experimental research, an in-depth discussion on noise reduction by adding a damping layer is carried out, and the direction of the main application of the damping layer is proposed.
