Abstract
The invention discloses an eccentric rotation power end structure of a reciprocation pump. A crankshaft is arranged on a case through bearings, and two rows of cylindrical roller bearings are arranged on the crankshaft. A swing wheel is arranged on the outer circle of each group of the cylindrical roller bearings. The swing wheels are connected with connection rods, and one end, connected with the corresponding swing wheel, of each connection rod is of a ball structure and can swing in a clamping groove of the corresponding swing wheel. Crosshead sliding ways are arranged on the case, the other end of each connection rod is connected with a crosshead through a crosshead pin, and a seal box is arranged between each connection rod and the corresponding crosshead sliding way. A motor drives the crankshaft of the pump to rotate through a large belt wheel, a small belt wheel and a belt; the crankshaft drives a crank throw to rotate eccentrically during rotation; the eccentric rotation of the crank throw drives the swing wheels to swing and reciprocate in the case by taking the connection rods as centers; meanwhile, the connection rods are driven to reciprocate and drive the crossheads to reciprocate. According to the eccentric rotation power end structure of the reciprocation pump, eccentric rotation of the crankshaft is converted to reciprocal rectilinear motions of the connection rods and the crossheads, and the eccentric rotation power end structure can be used for the reciprocation pump; the eccentric rotation power end structure of the reciprocation pump has the characteristics that the structure is simple, a few parts are adopted, the application range is wide and the pump efficiency is high.
