Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a force analysis method of a double-sided helical gear meshing transmission system of a high-power drilling pump. Background technique [0002] Drilling is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. The drilling pump is the most commonly used mechanical equipment in drilling, and the transmission system is an indispensable structure in the drilling pump. The traditional high-power three-cylinder drilling pump crankshaft transmission system uses single-sided herringbone gear meshing to transmit power. Since the gear is located at one end of the crankshaft, when the two cranks at the other end are stressed, the stress and deformation of the crankshaft are the largest. This phenomenon is more obvious when the power of the drilling pump is increased. In order to solve this problem, the crankshaft trans...
