Abstract: Less-teeth gear is increasingly promoted and applied because of the big single-stage transmission ratio, light weight, compact structure. The selection of gear parameters has been the key and difficult point of the design of less-teeth gear. At present design method involved in less-teeth gear design is rarely existed. According to the relationship between the characteristics and parameters of the less-teeth gear, using MATLAB for the optimization choice of the less-teeth gear, reasonable selection of the spiral angle and modification coefficient is realized, which can provide clues to further research of the less-teeth gear.

Abstract: In this paper, the gear acceleration noise model is first built up. The theoretical formula for calculating meshing acceleration noise is developed by dynamic analysis. Base on the impact theory, we first treat the gear meshing behavior as two variable radius cylinders, construct dynamics model, and then according to the industry standard to calculate sound pressure value one meter away by simulation,. Finally, we obtain the optimize equation according to the relation of parameters and noise.

Abstract: In this paper, an asymmetric double circular arc gear which is suitable for large-scale high-pressure gear pumps is introduced. While demonstrated its superiority, the displacement formula of the double circular arc gear pump is derived and the gear parameters are identified. The asymmetric double circular arc gear can meet the needs of large displacement and high pressure. There are advantages such as constant flow, no pulse, and no topping, which make this kind of gear has a bright future.
