Description
Technical field
The utility model belongs to the reciprocating pump field of field of petroleum machinery, refers to a kind of reciprocating note water pump transmission shaft Equilibrator especially.
Background technique
At present, the reciprocating note water pump transmission device that field of petroleum machinery uses is based on belt gearing down, and existing had fractional water flooding pump to adopt gear reduced drive device.The structure of gear reduced drive device includes external gear reduction unit and the built-in unilateral gear of power box slows down two kinds.External gear reduction unit floor space is comparatively large, and structure is not compact; Power box built-in unilateral gear slowing-down structure is compact, but when water injection pump power is larger, Helical gear Transmission wherein can produce larger axial force and radial force, the driving components such as bent axle, by force unbalance, bear alternate load for a long time, make crankshaft bearing eccentric wear, crank shaft oil seal leakage of oil, crankcase generates heat, and noise is large, and the working life of water injection pump reduces.
For above-mentioned problem, prior art proposes a kind of Double side gear-reduction unit of reciprocating type water flood pump, the stable drive of the transmission co-occurrence gear drive of this device, and noise is lower, and crankcase temperature is normal, extends the working life of water injection pump.The part but this technology still comes with some shortcomings, be mainly manifested in, because the rotating speed of transmission shaft is higher, be arranged in the driving gear of motor far-end at rotation process, there will be larger vibrations, such vibrations are comparatively large to the infringement of the driving cog of gear, need to change driving gear or driven gear frequently, improve the cost of use.And dismounting is repeatedly to being sealed with adverse influence.
Model utility content
The utility model proposes improvement opportunity scheme to the Double side gear-reduction unit of reciprocating type water flood pump of existing use, and by the technical program, the vibrations of the effective transmission shaft reduced, decrease the infringement to geared teeth.
The utility model is achieved through the following technical solutions:
A kind of reciprocating note water pump transmission shaft Equilibrator, includes motor, coupling, transmission shaft, gear, bent axle and crosshead;
Described gear includes two driving gears and two driven gears, is respectively the first driving gear, the second driving gear, the first driven gear and the second driven gear;
Described motor drives transmission shaft by coupling; Described transmission shaft is provided with described first driving gear and the second driving gear; The two ends of described bent axle are respectively arranged with described first driven gear and described second driven gear;
Described first driving gear coordinates with described first driven gear, and described second driving gear coordinates with described second driven gear; Described crosshead is connected with described crankshaft mobility;
On described transmission shaft, the neutral position of described first driving gear and described second driving gear is provided with damping device.
Described damping device is the truncated cone structure with center hole, and described transmission shaft is through described center hole.
The end face that in described truncated cone structure, diameter is little is relative with described second driving gear; The end face that in described truncated cone structure, diameter is large is relative with described first driving gear.
The side surface of described truncated cone structure and the centerlines of described truncated cone structure are less than 10 degree.
The beneficial effects of the utility model are:
Pass through the technical solution of the utility model, by being provided with damping device on transmission shaft, the rotation displacement of transmission shaft away from motor side can be reduced, namely the length of overhang is reduced, like this radial displacement of the second driving gear is reduced, there will not be the shaking force of the Contact of the second driving gear and the second driven gear, reduce the infringement of the driving cog to gear.
