Structural Analysis of High-power Cycloidal Pinwheel Drive for Drilling Rig Winch

Because the maximum power that can be transmitted by the ordinary cycloidal pinwheel reducer cannot meet the transmission applied to the drilling rig winch, the transmission part is improved, and the high-power cycloidal pinwheel transmission mechanism is designed. The three-dimensional model of the cycloidal pinwheel transmission mechanism was drawn by SOLIDWORKS software, the design of the two-piece cycloidal wheel in the ordinary cycloidal pinwheel reducer was changed to four cycloidal wheels, the needle tooth shell was partially reinforced, and finally the strength finite element analysis of the needle tooth shell and cycloidal wheel structure of the cycloidal pinwheel transmission mechanism was carried out by ANSYSWorkbench finite element software. Through the improvement, compared with the ordinary double-piece cycloidal pinwheel structure, the stress and deformation are reduced by 68.7% and 57%, and this new structure is more suitable for high-power cycloidal transmission.
