Abstract: Aiming at the problem that deformation and error reduced the meshing performance of assembled double helical gears transmission, the assembled double helical gear of the power transmission system of plunger pump was taken as the model, a study of the meshing characteristics of the double helical gears was executed by means of theoretical strength calculation, error analysis, simulation modification and test verification. Firstly, the structural form of the gear pair was analyzed, also, the contact strength and bending strength of the gear pair were analyzed and calculated, and the influence factors of gear contact strength and bending strength were analyzed. Then ,the error forms and compensation measures of the gear type were analyzed and discussed, also, the shaft deformation and tooth modification characteristics of assembled double helical tooth gear shaft were analyzed in the aspect of theory. Finally, based on the software platform of KISS soft software, the modification quantities of the gears were analyzed and calculated. The modification parameters were optimized by comparing the meshing spots, transmission errors and contact stress of the gear pairs with different modification quantities. And moreover, the results were used to process the sample products as a validation. The analysis results show that after compensating the influence of deformation and error on gear transmission characteristics, the peak-to-peak value of transmission error is reduced by 38%, the gear surface line load is reduced by 41.3%, the contact area of the gear surface is evenly distributed along the tooth direction, and the transmission meshing performance is improved.
Key words: gear transmission error; meshing performance; gear pair; tooth modification; KISS soft software; contact strength and bending fatigue strength; contact stress and meshing spots
