Description
Technical field
It the utility model is related to plunger pump technique field, the eccentric abrasion prevention bent axle of specially a kind of Novel plunger pump.
Background technology
The effect of plunger pump crankcase is by rotary motion by the rotary motion of power source such as diesel engine motor by connecting rod
Straight reciprocating motion is converted into, so as to drive plunger oil suction or oil extraction.Important component of the bent axle as plunger pump, its quality is directly
Influence the service behaviour of plunger pump.
Plunger pump crankshaft structure of the prior art, belt pulley is often fixedly mounted on the front end axle of bent axle and passes through belt
Transmission belt dynamic crankshaft rotates；Also the plunger pump crankshaft structure having is rotated using gear drive band dynamic crankshaft, and it is in plunger pump
Front end axle on fixation be arranged helical gear, helical gear is engaged by driving gear on power output shaft so as to drive plunger pump bent
Axle rotates, and the structure of its gear drive is generally unilateral gear built in external The gear deceleration and headstock and slowed down two kinds, outside
Put that gear reduction unit floor space is larger, and structure is not compact.
The plunger pump crankcase of prior art is primarily present following defect：
1st, the power source in crankcase is concentrated mainly on the front end axle of bent axle to the power of bent axle, although crankshaft two end leads to
Cross bearing to fix, but when power of plunger pump is larger, still can produce skew, cause crankshaft oil seal oil leak；
2nd, when power of plunger pump is larger, pulley drive or Helical gear Transmission on the axle of plug pump front end can produce larger
The driving member force unbalance such as axial force and radial load, bent axle, bent axle discontinuity can cause connecting rod to be contacted with rod journal
The abrasion in face, the reciprocating motion of connecting rod is influenceed, and because bent axle bears alternate load for a long time so that crankshaft bearing is easy to wear,
Crankcase heating is severe, and noise is big, and the service life of plunger pump reduces.
Utility model content
For in the prior art the defects of, problem to be solved in the utility model is：How to provide it is a kind of it is compact-sized,
The eccentric abrasion prevention bent axle of stress balance, Novel plunger pump not easy to wear, service life length.
In order to solve above-mentioned technical problem, the technical scheme that this practicality newly newly uses is as follows：
A kind of eccentric abrasion prevention bent axle of Novel plunger pump, including front end axle, rod journal, trunnion and rear axle, it is crucial
It is：Fixed cover is provided with driven gear on trunnion in the middle part of bent axle, the driven gear with the power output shaft in crankcase
Driving gear be meshed, drive the bent axle to rotate by gear drive；The bent axle is at least provided with three rod journals, institute
Rod journal to be stated with big end to be connected, small end of connecting rod is connected with plunger, and the bent axle rotation drivening rod pumps,
So as to drive plunger to pump, oil suction is moved downward, moves oil extraction upwards；The front end axle and rear axle of the bent axle point
Other fixed cover is provided with bearing, is fixedly mounted on by bent axle described in the bearing in crankcase.
According to the above-mentioned technical solution, the utility model is arranged driven tooth by fixation on the trunnion in the middle part of bent axle
Wheel, the driven gear are meshed with the driving gear on the power output shaft in crankcase, and the song is driven by gear drive
Axle is rotated, and to move back and forth, so as to drive plunger to pump, convert rotational motion is moved downward into suction by connecting rod
Oil, oil extraction is moved upwards.The stress of bent axle is set to be put down at the middle part of bent axle so as to reach stress by said structure the utility model
Weighing apparatus.Compared with traditional plunger pump crankcase front end stress, the utility model stress more balances, and reduces the skew of bent axle, avoids
Crankshaft oil seal oil leak, and reduce the abrasion of connecting rod and rod journal contact surface, there is a constant volume to the service life for increasing bent axle
Pole acts on.
Further, the driven gear and the main bearing journal integrally connected.Integrally connected, compact-sized, performance
It is more reliable and more stable.
Further, the driving gear is connected with motor power output shaft.
Further, the driving gear is connected with belt pulley power output shaft, passes through belt passing power.
Further, the number of the connecting rod neck of the bent axle is even number, and is symmetrically distributed in the main shaft of bent axle middle
Neck both sides, the driven gear are fixed and are set on the trunnion of bent axle middle.The number of connecting rod neck is even number, symmetrical
Distribution, driven gear are fixedly installed on the trunnion of bent axle middle, and stress more balances, and eccentric abrasion prevention effect is more preferable.
Further, the driving gear and the driven gear are deceleration transmission.
