The utility model discloses reduced the diameter of eccentric wheel, the central point who has reduced the slush pump puts, has reduced the complete machine volume of slush pump, adopts the left -hand teeth wheel and the dextrorotation gear of two components of a whole that can function independentlys, makes the atress of bent axle and transmission equitable more balanced, has reduced the processing cost simultaneously.
Description
Technical field
The utility model is related to petroleum drilling and mining mud pump equipment technical field, and specifically a kind of slush pump three-level is eccentric
Double gear-ring bent axle.
Background technology
Traditional slurry pump crank can be divided into entirety and split two big class.In order to meet stroke needs, slurry pump crank
Eccentric wheel is substantially in the case of coaxial, directly passes through oblique shoulder transition or separable assembled once, is displaced to required
Eccentric distance.Adopting casting crankshaft traditional slush pump, the eccentric wheel of casting crankshaft is relatively large in diameter, and needs to raise slush pump more
Center, the overall volume of final equipment is larger, causes the difficulty transported, install.Conventional crankshafts use herringbone tooth
Circle, cost is more expensive, and its arrangement form is " crank crank herringbone shaped ring gear crank ", and this arrangement form makes bent axle
Stress is not uniform, easily produces vibrations during crankshaft operation, affects equipment reliability of operation.
Utility model content
The purpose of this utility model be a kind of slush pump three-level bias Double-gear bent axle is provided so that the stress of bent axle more
Rationally, equalize, and reduce slush pump center, reduce the package size of slush pump.
For achieving the above object, technical solution adopted in the utility model is:
A kind of slush pump three-level bias Double gear-ring bent axle, it includes crankshaft body, and described crankshaft body includes two spindle noses,
It is provided with three transition axises that interconnective axial line is arranged successively in 120 ° of dislocation, the middle part of each transition axis sets between spindle nose
There is eccentric boss, the eccentric throw between the central axis of transition axis and the central axis of spindle nose is e1, the central axis of transition axis
The eccentric throw and central axis of eccentric boss between is e2；The outside of each eccentric boss is mounted on eccentric wheel, eccentric wheel
Central axis and the central axis of eccentric boss between eccentric throw be e3；It is provided with gear convex between two neighboring transition axis
Platform, the axial line of gear boss is coincided with the axial line of spindle nose.
Preferably, the axial line of three described eccentric wheels is in 120 ° of dislocation arrangements.
Preferably, two described gear boss are separately installed with left-handed gear and dextrorotation gear, left-handed gear, right-hand teeth
Bonded structure is adopted between wheel and gear boss.
Preferably, the indentation of described left-handed gear and dextrorotation gear exterior is symmetrically set.
The beneficial effects of the utility model are:
Exist partially between the central axis of transition axis and the central axis of spindle nose in crankshaft body described in the utility model
The heart is away from e1, between the central axis of the central axis of transition axis and eccentric boss, there is eccentric distance e 2, the central axis of eccentric wheel
There is eccentric distance e and the central axis of eccentric boss between3, constitute three-level eccentric structure bent axle, and the axle of three transition axises
Heart line be in 120 ° of dislocation arrangements so that the stress of bent axle, transmission more rationally, equilibrium, improve the stability of equipment operation；
The utility model passes through the setting of three-level eccentric structure bent axle, reduces the diameter of eccentric wheel, effectively reduces mud
The center of stock pump, reduces the machine volume of slush pump, reduces production cost；
The utility model instead of traditional herringbone toothed ring gear using the left-handed gear of two splits and right-hand teeth wheel, makes song
The stress of axle and transmission more rationally equalize, and reduce processing cost simultaneously.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail.
A kind of slush pump three-level bias Double gear-ring bent axle, it includes crankshaft body 1, and crankshaft body 1 includes two spindle noses 2,
It is provided with three transition axises 3 that interconnective axial line is arranged successively in 120 ° of dislocation, in each transition axis 3 between spindle nose 2
Portion is provided with eccentric boss 4, and the eccentric throw between the central axis of the central axis of transition axis 3 and spindle nose 2 is e1, transition axis 3
Eccentric throw between the central axis of central axis and eccentric boss 4 is e2；The outside of each eccentric boss 4 is mounted on bias
Wheel 7, the eccentric throw between the central axis of the central axis of eccentric wheel 7 and eccentric boss 4 is e3, the axle center of three eccentric wheels 7
Line is in 120 ° of dislocation arrangements；It is provided with gear boss 8, the axial line of gear boss 8 and spindle nose 2 between two neighboring transition axis 3
Axial line coincides.Left-handed gear 5 and dextrorotation gear 6, left-handed gear 5, dextrorotation gear are separately installed with two gear boss 8
Bonded structure is adopted between 6 and gear boss 8.Indentation outside left-handed gear 5 and dextrorotation gear 6 is symmetrically set.
The utility model passes through the setting of three-level eccentric structure bent axle, reduces the diameter of eccentric wheel, effectively reduces mud
The center of stock pump, reduces the machine volume of slush pump；Left-handed gear and right-hand teeth wheel using two splits instead of
Traditional herringbone toothed ring gear, makes the stress of bent axle and transmission more rationally equalize, reduces processing cost simultaneously.
