Background technique
At present, the power end structure of Five-cylinder piston pump mainly drives crank rotation by bull gear, bent axle is equipped with connecting rod and slide block, converts rotary motion to to-and-fro motion.Bull gear drive form has two kinds, namely one-sided driving driving with bilateral, as shown in Figure 1 and Figure 2.
WQ 2700 Five-cylinder piston pump of FMC Corp., as shown in Figure 1, adopts one-sided driving.Gear-box 2 is arranged in left side or the right side of bent axle 1, is with dynamic crankshaft 1 to rotate by gear 2, and the deficiency of this structure is, there is unbalance loading problem, the stationarity of pump can be caused to be deteriorated, noise rising etc.
QHB 2500 Five-cylinder piston pump of SPM company, as shown in Figure 2, adopt bilateral driving, gear-box is arranged in the two ends of bent axle, is divided into left-hand teeth roller box and right-hand teeth roller box.Rotate because left-handed gear 5 and dextrorotation gear 4 are distributed in both sides band dynamic crankshaft 1, stationarity and mechanical characteristic are greatly improved, but its huge structure, takes up room comparatively large, be unsuitable for being configured on the equipment such as fracturing unit truck, reduce applicability.
Summary of the invention
The object of this invention is to provide a kind of Five-cylinder plunger pump crankshaft structure, solve in prior art and there is unbalance loading, cause stationarity to be deteriorated, the problem that noise raises; Or there is huge structure, the problem of inconvenience configuration.
The technical solution adopted in the present invention is, a kind of Five-cylinder plunger pump crankshaft structure, the land of horizontal axis is provided with in frame, land excircle is set with bull gear, bearing is provided with between land and bull gear, land axle center is provided with connecting cylinder, bull gear is coaxially connected with gear ring gland, gear ring gland is coaxially connected with connecting cylinder, connecting cylinder two ends are coaxially connected with right bent axle gland, left bent axle gland simultaneously, right bent axle gland is fixedly connected with right bent axle, and left bent axle gland is fixedly connected with left bent axle.
The invention has the beneficial effects as follows, adopt bull gear midway drive form, bent axle is divided into left bent axle and right bent axle two-part, operates steadily, compact structure, volume is little, and quality is light, uses reliable.On the basis ensureing power end transmission performance, improve space availability ratio, be applicable to being configured in the space-saving equipment of needs, especially on fracturing unit truck, for Five-cylinder piston pump provides, a kind of stress performance is good, space availability ratio is high, the crankshaft structure of easy accessibility; In addition, the axial force that bull gear will be born of this structure and radial force are transferred directly in frame without bent axle.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The crankshaft structure mainly integrated type of existing plunger pump, by arrangement of gears at the one-sided of bent axle or bilateral, as shown in Figure 1 and Figure 2, comprises bent axle 1, gear-box 2, dextrorotation gear 4 and left-handed gear 5.Plunger pump power end structure mainly bent axle-bar linkage structure, the position of gear on bent axle and mode have influence on the stressed of bent axle and physical dimension, and then have influence on structural type and the size of plunger pump, are one of key influence factors of plunger pump.
As shown in Figure 3, Figure 4, Five-cylinder plunger pump crankshaft structure of the present invention, power end of plunger pump is set to split type bent axle.The crankshaft structure of plunger pump comprises right bent axle 6, left bent axle 7, bull gear 8, connecting body 9, connecting cylinder 10, right bent axle gland 11, gear ring gland 12, land 13, bearing 14 and left bent axle gland 15.Bull gear 8 between left bent axle 7 and right bent axle 6, for driving left bent axle 7 and right bent axle 6 synchronous axial system.
The concrete structure of Five-cylinder piston pump bent axle of the present invention is, the land 13 of horizontal axis is fixedly installed in frame 3, land 13 excircle is set with bull gear 8, bearing 14 is provided with between land 13 and bull gear 8, land 13 axle center is provided with connecting cylinder 10, bull gear 8 is coaxially connected with gear ring gland 12, gear ring gland 12 is coaxially connected with connecting cylinder 10, connecting cylinder 10 two ends are coaxially connected with right bent axle gland 11, left bent axle gland 15 simultaneously, right bent axle gland 11 is fixedly connected with right bent axle 6, and left bent axle gland 15 is fixedly connected with left bent axle 7.
Between bull gear 8 and gear ring gland 12, between gear ring gland 12 and connecting cylinder 10, connecting cylinder 10 simultaneously and right bent axle gland 11, all adopt spline joint between left bent axle gland 15; Right bent axle gland 11 and right bent axle 6, with bolts between left bent axle gland 15 and left bent axle 7; Installation location when right bent axle 6 and left bent axle 7 realize original state by connecting body 9.
