Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a force analysis method of the double-sided helical gear meshing transmission system of the high-power drilling pump, so as to overcome the inability of the traditional force analysis method of the single-side herringbone gear meshing transmission system of the drilling pump. It is used for the force analysis of the double-sided helical gear meshing transmission system of the high-power drilling pump, and provides a force analysis method for the double-sided helical gear meshing transmission system of the high-power drilling pump. Calculation of the safety factor of each acting force in the side helical gear meshing transmission system and the sudden change section of the crankshaft and transmission shaft lays the foundation for the design and optimization of the double side helical gear meshing transmission system of the high-power drilling pump

Embodiment 1

[0090] The principle of double-sided helical gear meshing transmission system of high-power drilling pump is as follows: figure 1 As shown, the power is input from the right end of the drive shaft, and the crankshaft and drive shaft are shown as Figure 3 ~ Figure 4 shown.

[0091] 1) Kinematic relationship of the crank-link mechanism

[0092] The displacement, velocity and acceleration of the piston can be determined from the geometric relationship and kinematic relationship of the crank-link mechanism, such as Figure 5 As shown, taking the positive direction of the X-axis as the positive direction, the displacement origin of the piston is at the rear dead center 5-1, and the crankshaft rotation angle Count from the front dead center, that is, φ=0 at this time, S=2R, and the crankshaft rotates clockwise. In order to facilitate the calculation, it is considered that the crankshaft rotates at a constant speed. It can be known from theoretical derivation that the calculatio...

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...
