“…C stands for compression and T for tension. Previous research results have demonstrated that the load distribution law of C-T and T-C cases are similar, and so are T-T and C-C cases (Yao et al, 2021). Accordingly, this paper selects C-T and C-C cases for analysis.…”

“…On the other hand, however, up to now, only few attempts have been made to improve the load distribution of PRSM. Zhang et al (2016) and Yao et al (2021) proposed a method of uniform load distribution that considers compensation for the cumulative deformation of the shaft through pitch matching and tooth thickness adjustment. The pitch adjustment they proposed is relatively tiny, usually about 1 μm, which brings forward a great challenge for the existing processing level.…”

Planetary roller screw mechanism (PRSM) is a novel high-performance linear transmission device. The non-uniformity of load distribution over PRSM threads is a vital problem severely affecting its load-carrying capacity and service performance. This work aims to develop a PRSM load distribution improvement approach with good manufacturability and general applicability. A roller taper modification method for load distribution optimization is proposed based on the deformation compatibility and force equilibrium, then the roller grinding experiment is carried out. Finally, the effects of external load and thread number on load sharing optimization are analyzed to examine the applicability. The results show that the maximum reduction in load sharing coefficient reaches 31.4% after roller taper modification under the case studied. The taper modification of roller threads could be rapidly implemented by only adjusting the roller grinding angle. The roller grinding experiment results agree well with the theoretical values, and the maximum error is no more than 2 μm. As the external load and thread number change, the improvement approach still works well. The proposed method has been verified by comparisons with finite element simulations and available references. This work can provide theoretical guidance for the optimal design of PRSM and has good engineering application prospects.

“…Sandu et al 52 presented a general method considering the profile shape of the thread to meet the design requirements of many types of PRSM and deduced the surface equations under three helical profile shapes, which are applied to both standard and inverted PRSM. Yao et al 53 proposed an improved optimization method which can solve the non-convergence of calculation caused by machining error. The load distribution on both the screw-roller and nut-roller interfaces is more uniform by searching the best designed pitches.…”
