Strength Analysis of High-power Drilling Pump Crankshaft with Double Side Helical Gear Drive
摘要
Abstract
Crankshaft drive structure in traditional high-power three cylinder drilling pump uses a pair of meshing herringbone gears to transmit power.As the gear is located at one end of the crankshaft,the stresses and deformation of the crankshaft are the biggest when the other end of the two cranks are stressed.In order to alleviate this situation,the crankshaft drive structure of some high-power drilling pump uses two pairs of meshing helical gears to transmit power.For this kind of crankshaft drive structure,the formulas of two gears meshing force,bearing reaction force and torque and bending moment at the cross-section mutation are deduced.The strength of the crankshaft was checked,and the strength analysis via finite element method was done by using workbench ANSYS.The analysis results show that the maximum stresses on the most dangerous section on both sides of the middle crank of the transmission crankshaft with double side helical gear are reduced by 21.3％ and 11.5％ respectively comparing with the traditional transmission crankshaft.And the maximum deformation is of 45.3％ lower than that of the traditional transmission crankshaft,the strength and stiffness are improved.At the same time,it can improve the strength of crankshaft by appropriately increasing the fillet value of the crankshaft.关键词
