Abstract
An F type slurry pump comprises a frame assembly, a power end assembly, a crankshaft assembly, a cross head assembly, lubrication and cooling mechanisms of each part, a hydraulic end assembly and a base, and is characterized in that the power end assembly has a herringbone gear shaft and an integrated herringbone gear ring meshing with the herringbone shaft; the herringbone gear ring is connected with the crankshaft in to a whole through bolt and piston nut; in addition, a connecting rod is connected with the crankshaft. Compared with the prior art, the utility model changes the prior medium soft tooth flank into a rigid tooth flank without changing the prior installing dimension; meanwhile, the utility model adopts monolithic machining of herringbone gear so as to overcome machining difficulty, increase transmission accuracy of the power end, reduce weight and improve installation condition; moreover, the utility model which accelerates batch production rate and prolongs the service life of slurry pump overcomes the disadvantages caused by the actuality that the prior big herringbone gear is assembled by two bevel gears because the prior F type slurry pump adopts medium soft tooth flank.
Description
One, technical field
The utility model relates to a kind of slurry pump, particularly relates to a kind of oil, geological drilling with horizontal three cylinder single action piston pumps, i.e. F type slurry pump.
Two, background technique
The F series slurry pump is horizontal three cylinder single-action reciprocating reciprocating pumps, in order to circulating mud.Longer because of its stroke, can remain under the lower jig frequency and use, with the working life of prolongation fluid end easily damaged parts, thereby fluid end is more durable than conventional mud pump, and has greatly improved the service behaviour of triplex mud pump.Yet the mechanism of action of F series pump is with slurry pump is unanimous on the whole both at home and abroad, the material of major part and structural type thereof are also roughly the same, and its structure is very complicated, the efficient of manufacturing is very low, the device fabrication cost is very high, process-cycle is long, is unfavorable for current manufacturing development, can not satisfy the demand of petroleum industry, especially power end transmission system, be that the gear pair of the soft flank of tooth carries out transmission in adopting, the herringbone profile of tooth of its little herringbone gear is whole processing, and middle tool withdrawal groove is very little, has only 6mm, a because left side, tool withdrawal groove is little between the right-hand teeth, thereby makes processing left, right-hand teeth is difficulty especially, and the method that solves this difficult point has following two kinds: first kind, on SYKE1600 type gear generator, process, a roughing left side, right-hand teeth, semi finishing left side right-hand teeth again, fine finishing left and right sides hand-screw tooth more at last.Second kind, roughing left-hand teeth on general hobbing machine, roughing right-hand teeth, fine finishing left side right-hand teeth on SYKE1600 type gear generator more again.From its process route and course of working, the former design of the herringbone gear of little tool withdrawal groove makes the process-cycle very long, and the tooth accuracy of processing is very low, does not usually reach the drawing designing requirement.Simultaneously, big herringbone gear does not have tool withdrawal groove, form with the combination of two halves helical gear, its bull gear left side right-hand teeth carries out separate machined, assembles with bolt again, and the error of centralization of bull gear herringbone tooth is big like this, transmission accuracy is low, vibration and noise are also very big, make the life-span of slurry pump reduce, and have run counter to the design original intention of F type slurry pump.
In sum, little tool withdrawal groove or the slurry pump transmission system of not having a tool withdrawal groove herringbone gear make its process-cycle long, and manufacturing efficiency is low, and difficulty of processing is big, and its design proposal has lagged behind current advanced person's gear machining technology, is unfavorable for its mass production.
Three, summary of the invention
It is horizontal three cylinder single-action reciprocating reciprocating pumps that the purpose of this utility model is to provide a kind of F type slurry pump, and the transmission structures complexity, the manufacturing efficient that solve existing F series slurry pump are low, and service time is short, the problem of assembling difficulty.
Purpose of the present utility model can reach by the following technical programs, it is this F type slurry pump, comprise lubricated and cooling mechanism, fluid end assembly and the base at support assembly, power end assembly, crank assemblby, cross head assembly, each position, it is characterized in that: the integrated type herringbone gear ring that described power end assembly has a herringbone gear shaft and is meshed with it; This herringbone gear ring connects as one by bolt, piston unt and bent axle, and connecting rod is connected with bent axle.
The flank of tooth of described herringbone gear shaft and herringbone gear ring is the hard flank of tooth;
The left and right position of revolving the tooth transition of described herringbone gear shaft and integrated type herringbone gear ring is equipped with the tool withdrawal groove that its width is enough to guarantee that herringbone tooth processing is carried out smoothly.
According to the above-mentioned F type slurry pump that assembles, during work, herringbone gear shaft drives the motion of herringbone gear ring, thereby also drives the bent axle motion, and bent axle drives piston motion by connecting rod, thereby realizes the work of slurry pump.Being characterized as of its power end transmission system: under the form that does not change original installation, the flank of tooth is the hard flank of tooth, and tooth-face roughness improves, enough tool withdrawal grooves are left in the centre, adopt Gear Processing technology fast, usually are gear hobbing, roll flute again reaches the purpose of quick manufacturing.
The utility model compared with prior art, at first, adopt the hard flank of tooth herringbone gear of integrated type transmission, because tooth face hardness improves, also the accuracy of gear has been improved, therefore the contact strength of gear pair and flexural strength also improve greatly, just can correspondingly reduce for the required effective engagement facewidth of gear, and so total facewidth is constant, effectively the engaging tooth reductions is little, the tool withdrawal groove width just increases, and can satisfy the requirement of gear hobbing, roll flute fully, thereby reduce manufacture cost and process-cycle.Secondly, by the herringbone gear transmission is carried out tip relief, repair to, gear contact strength and flexural strength have been improved so again, make the engagement running of its gear driving pair more steady, solve not high vibration that brings of traditional gear-shaping precision and noise problem, thereby prolonged the working life of slurry pump; The 3rd, reduced because gear operation is not steady, and the fluid end piston operating mode shakiness of bringing has reduced the wearing and tearing of cylinder sleeve.The 4th, because the gear pair of the hard flank of tooth is more wear-resisting than soft tooth flank gear pair, for long running, the wearing and tearing of the flank of tooth are very little, by the test to the F1600 slurry pump, this slurry pump is smooth running always in use, has reduced to reduce because of the gear operation imbalance causes the life-span.
The utility model has solved galloping in traditional F type slurry pump transmission system, and noise is big, and the herringbone gear process-cycle is long, the problem that precision is low.Make F type slurry pump transmission system be suitable for the fast processing method of modern gear, thereby improved the manufacturing efficient of F type slurry pump, make F type slurry pump enter fast development and play an important role, can realize considerable economic.
