The article is devoted to the actual problem of increasing the performance indicators of machine gear drives. To solve this problem, in the article proposed to use a conchoidal engagement made with a shifting of the  reference profile and special contact conditions. A feature of the proposed engagement is that it is less sensitive to manufacturing and assembly errors compared to conventional conchoidal engagement. As a result of theoretical studies, the performance indicators of such an engagement were determined. This made it possible to determine the level of load during further experimental tests of new gears. Contact strength and meshing losses were selected as performance indicators subject to further experimental verification. The ratios of these indicators, calculated for conchoidal spur gears with convex-convex contact, made with a shifting of the reference profile, with similar involute ones, are theoretically determined. Comparative analysis of performance indicators was carried out for gears of involute and conchoidal engagement with the same parameters and shifting of the reference profile. It was found that for experimental conchoidal drives with shifting, the maximum load is 1.2 times higher than that of a similar involute drive with shifting, and the loss in engagement is 21% less. A rational area of application of the new gearing is machine drives for high power transmissions. Keywords: spur gears, conchoidal gearing, profile shift, convex-convex contact, meshing characteristics, teeth surface strength, gearing power loss

Meshing Characteristics

The theoretical and experimental investigations on gear drive with tubular meshing surfaces are studied in this paper. Based on the theory of conjugate curves, parametric design for tubular tooth profiles is provided, and solid models are established. The performance evaluation of tubular meshing surfaces is carried out according to geometric and meshing characteristics analysis. The meshing essence of tubular tooth surfaces is revealed. Mechanics property of tooth surfaces is analyzed by finite element model. The contact stress, meshing law and deformation of tooth surfaces are introduced, respectively. Transmission efficiency experiment is made based on the developed gear prototype, and a comparison with involute gear drive is also shown. The further study on the dynamics analysis and key manufacturing technology will be carried out, and it is expected to have excellent transmission performance.
