Description
Technical field
The invention belongs to the oil drilling and r eoovery machine equipment technical field, be used to cement the well, the reciprocating plunger pump of pressure break and acidizing unit, be specifically related to a kind of Five-cylinder piston pump crankshaft structure.
Background technique
At present, the power end structure of Five-cylinder piston pump mainly is to drive bent axle by bull gear to rotate, and connecting rod and slide block are housed on the bent axle, and will rotatablely move converts to-and-fro motion to.The bull gear drive form has two kinds, and is promptly one-sided driving driving with bilateral, like Fig. 1, shown in Figure 2.
WQ 2700 Five-cylinder piston pumps of FMC Corp., as shown in Figure 1, adopt one-sided driving.Gear-box 2 is arranged in the left side or the right side of bent axle 1, drives bent axles 1 by gear 2 and rotates, and the deficiency of this structure is, has the unbalance loading problem, can cause the stationarity variation of pump, noise rising etc.
QHB 2500 Five-cylinder piston pumps 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.Because left-handed gear 5 is distributed in both sides with dextrorotation gear 4 and drives bent axle 1 rotation, stationarity and mechanical characteristic are greatly improved, and still, its structure is huge, and it is bigger to take up room, and is inappropriate on the equipment such as being configured in fracturing unit truck, has reduced applicability.
Summary of the invention
The purpose of this invention is to provide a kind of Five-cylinder piston pump crankshaft structure, solved and have unbalance loading in the existing technology, cause the stationarity variation, the problem that noise raises; Perhaps exist structure huge, the problem of inconvenience configuration.
The technological scheme that the present invention adopted is, a kind of Five-cylinder piston pump crankshaft structure is provided with the land of horizontal axis in frame; Be set with bull gear on the land excircle; Be provided with bearing between land and the bull gear, the land axle center is provided with connecting cylinder, and bull gear is connected with the gear ring gland is coaxial; The gear ring gland is connected with connecting cylinder is coaxial; Connecting cylinder two ends while and right bent axle gland, left coaxial connection of bent axle gland, 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 the middle drive form of bull gear, bent axle is divided into left bent axle and right bent axle two-part, operate steadily, compact structure, volume is little, and light weight is used reliable.On the basis that guarantees the power end transmission performance, improve space availability ratio, be fit to be configured on needs space-saving equipment, the especially fracturing unit truck, a kind of stress performance is good, space availability ratio is high, the crankshaft structure of easy accessibility for Five-cylinder piston pump provides; In addition, this structure will directly be transferred to axial force and radial force that bull gear bears on the frame without bent axle.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
The crankshaft structure of existing plunger pump mainly is an integrated type, with the one-sided or bilateral of arrangement of gears at bent axle, like Fig. 1, shown in Figure 2, comprises bent axle 1, gear-box 2, dextrorotation gear 4 and left-handed gear 5.Plunger pump power end structure mainly is bent axle-bar linkage structure, the stressed and physical dimension that position and the mode of gear on bent axle has influence on bent axle, and then have influence on the structural type and the size of plunger pump, be one of key influence factor of plunger pump.
Like Fig. 3, shown in Figure 4, Five-cylinder piston pump crankshaft structure of the present invention, the plunger pump power end 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 is used to drive left bent axle 7 and rotates synchronously with right bent axle 6 between left bent axle 7 and right bent axle 6.
The concrete structure of Five-cylinder piston pump bent axle of the present invention is; In frame 3, be set with the land 13 of horizontal axis, be set with bull gear 8 on land 13 excircles, be provided with bearing 14 between land 13 and the bull gear 8; Land 13 axle center are provided with connecting cylinder 10; Bull gear 8 and 12 coaxial connections of gear ring gland, gear ring gland 12 and 10 coaxial connections of connecting cylinder, connecting cylinder 10 two ends simultaneously with right bent axle gland 11,15 coaxial connections of left bent axle gland; 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 the gear ring gland 12, between gear ring gland 12 and the connecting cylinder 10, connecting cylinder 10 all adopts spline to be connected simultaneously with between right bent axle gland 11, the left bent axle gland 15; The employing bolt is connected between the right bent axle gland 11 and right bent axle 6, left bent axle gland 15 and left bent axle 7; Installing and locating when right bent axle 6 is realized original state with left bent axle 7 through connecting body 9.
As shown in Figure 3, when crankshaft structure embodiment one of the present invention installed pattern for the left side, adopting right bent axle 6 was that three to turn with left bent axle 7 be two to turn structure.As shown in Figure 4, when crankshaft structure embodiment two of the present invention installed pattern for the right side, adopting right bent axle 6 was that two to turn with left bent axle 7 be three to turn structure.
When apparatus of the present invention are installed; As shown in Figure 3; Right bent axle 6, connecting body 9, connecting cylinder 10, right bent axle gland 11, land 13, bearing 14, gear ring gland 12, bull gear 8, left bent axle gland 15 and left bent axle 7 are installed successively, simultaneously, are guaranteed the location of bent axle on frame.During dismounting, oppositely dismounting gets final product successively.Structure as shown in Figure 4, but the mounting or dismounting of analogy structure shown in Figure 3 are installed and removed in proper order.
During apparatus of the present invention work; Bull gear 8 drives connecting cylinder 10 through splined; Connecting cylinder 10 drives left bent axle gland 15 and rotates synchronously with right bent axle gland 11, and left and right sides bent axle gland adopts bolt to be connected respectively with left and right sides bent axle, realizes driving the synchronous rotation of left bent axle 7 and right bent axle 6.The axial force and the radial force that produce in bull gear 8 engagement processes in addition, the bent axle without the left and right sides directly passes on the frame 3 through land 13.
Apparatus of the present invention operate steadily, compact structure, and it is convenient to change, and uses reliable; Can the load of bull gear directly be transferred on the frame without bent axle, so load-carrying properties are good, complete machine is in light weight.
