Abstract
The utility model relates to a five-cylinder pump crankshaft, comprising five connecting rod journals. The axial sequence is 1-2-3-4-5, and the connecting rod journals are uniformly distributed in the range of 360 degrees according to the sequence of 1-3-5-2-4. The position where the central axis of each connecting rod journal is positioned is provided with an axial bore, and the axial bore penetrates the entire axle. An axial bore communicated with the axle journal of the adjacent chief axle is respectively arranged at the center of each gear journal. The centered point of each connecting rod journal is provided with a radial bore which is connected with the axial bore. The axle journal of every chief axle is provided with a bore which is vertically communicated with the adjacent connecting rod journal or the axial bore of the gear journal, and both ends of the axial bore of each connecting rod journal are provided with sealing elements. The center of the end face of each gear journal is provided with an oil conduit positioning hole and a fixing threaded hole. The pressure lubrication passes through the conduit and enters from the two ends of the bent axle and fills the perforated oil conduit in the bent axle, and then the pressure lubrication flows out from the oil holes of the axle journal of each chief axle and the connecting rod journal. The bearing or the bush which is positioned at the oil hole is lubricated. The five-cylinder pump crankshaft makes the discharge capacity of the oscillating displacement pump big and uniform, and the volume is small and the oscillation is also small.
Description
Technical field:
The utility model relates to bent axle, especially the bent axle in the employed reciprocating pump of oil drilling.
Background technique:
In the drilling well in oil field, well cementation, fracturing work, all to use reciprocating pump.Present employed reciprocating pump mostly is a triplex pump, and this pump has the shortcoming that volume is big, the uneven vibration of discharge capacity is big; In addition, lubricated common the taking of triplex pump bent axle realized by two kinds of approach: the main shaft necked part obtains from pump case bearing support punching oil-feed; The rod journal part then is to beat the inclined hole Oil Guide from the main shaft axle journal to rod journal.Beat inclined hole on rod journal from the main shaft axle journal, the position accuracy demand height wants to guarantee that inclined hole is just in time in the intermediate portion of rod journal.This structure makes especially difficulty of processing.
Summary of the invention:
The purpose of this utility model is for the little discharge capacity of design volume is big evenly and vibrate five little cylinder pumps bent axle is provided, and changes the lubricating system of bent axle, makes the oilhole on it be easy to processing.
The technological scheme that realizes above-mentioned purpose is: referring to accompanying drawing, five cylinder pump bent axles, two ends are gear axle journals 1, the stage casing is alternate main shaft axle journal 2 and rod journal 3, the main shaft axle journal is adjacent with the gear axle journal, has gear positioning spline 4 on the gear axle journal, the end face of the main shaft axle journal adjacent with the gear axle journal has gear fixing threaded hole 5, main shaft axle journal middle part has oil groove circle 6, it is characterized in that, rod journal is five, axial order is 1-2-3-4-5, according to uniform in 360 ° of the job orders of 1-3-5-2-4, position at each rod journal central axis place, has the axial bore 7 that connects holoaxial, center at each gear axle journal, axial bore 8 with the adjacent main shaft axle journal of a feeding, middle part has one and leads to the wherein radial hole 9 of axial bore 7 on each rod journal, on each main shaft axle journal, have one with adjacent rod journal or gear axle journal in axial bore 7 or the 8 vertical holes that communicate 10, axial bore two ends in each rod journal have Sealing, and the end face center of each gear axle journal has oil pipe positioning hole 12 and fixing threaded hole 13.
The Sealing at axial bore 7 two ends can be seal plug 11 or is embedded with the seal disc 14 of seal ring in the described rod journal, is locked by bolt 15.
Power imports bent axle into by gear makes its rotation, and each pump head that is connected in rod journal is finished suction and discharge according to the order of 1-3-5-2-4.Pressure lubrication oil enters and is full of the oil pipe that connects in the bent axle from crankshaft two end by pipeline, and the oilhole on each main shaft axle journal and rod journal flows out, the bearing or the bearing shell at lubricated this place.
The utility model has the advantages that:
1. five cylinder crankshafts make reciprocal pump delivery big and evenly and volume is little, the vibration is little.
2. changed the lubricating system of bent axle, the lubricant oil that makes main shaft axle journal and rod journal place saves and processes oilhole and beat the big Oil Guide inclined hole of difficulty of processing on the pump case bearing support on bent axle from the bent axle body, and also sieve has been changed lubricating pipe simultaneously.
3. connecting the oilhole of oil duct in the formation bent axle, is on the axial cross section or radial cross section of bent axle, thereby processing is greatly easy.Through hole on the bent axle has also alleviated the weight of bent axle.

Claims (2)
1. five cylinder pump bent axles, two ends are gear axle journals, the stage casing is alternate main shaft axle journal and rod journal, the main shaft axle journal is adjacent with the gear axle journal, has the gear positioning spline on the gear axle journal, the end face of the main shaft axle journal adjacent with the gear axle journal has the gear fixing threaded hole, main shaft axle journal middle part has the oil groove circle, it is characterized in that, rod journal is five, axial order is 1-2-3-4-5, according to uniform in 360 ° of the job orders of 1-3-5-2-4, the position at each rod journal central axis place has the axial bore that connects holoaxial, center at each gear axle journal, have an axial bore that feeds adjacent main shaft axle journal, middle part has one and leads to the wherein radial hole of axial bore on each rod journal, on each main shaft axle journal, have one with adjacent rod journal or gear axle journal in the vertical hole that communicates of axial bore, axial bore two ends in each rod journal have Sealing, and the end face center of each gear axle journal has oil pipe positioning hole and fixing threaded hole.
2. according to a kind of five cylinder pump bent axles of claim 1, it is characterized in that the Sealing at the axial bore two ends in the described rod journal for seal plug or be embedded with the seal disc of seal ring, is locked by bolt.
