Abstract
The utility model relates to a gu well equipment machinery original paper, in particular to plunger pump bent axle. The utility model discloses a plunger pump bent axle comprises trunnion, connection axle journal and crank arm, be provided with a plurality of crank arms on the trunnion, be provided with the connection axle journal between two adjacent crank arms, every connects axle journal for the setting of all squinting of the axis direction of trunnion, every connects the inside oil duct that all is provided with the crank arm at through connection axle journal and both ends along the axis direction of axle journal, it is stifled that oil duct both ends port department all installs oil. The utility model discloses an oil pump bent axle simple structure, the oil duct leakproofness is better, and the seal structure simple installation, and the effectual bent axle oil duct of having avoided influences the situation of connecting rod bearing shell and crankshaft bearing's lubrication because of a variety of causes arouses the oil leak, has improved the reliability of crankshaft drive.
Description
Technical field
The utility model relates to a kind of cementing equipment machinery original paper, particularly a kind of plunger pump bent axle.
Background technique
Bent axle effect is straight line motion through connecting rod by convert rotational motion by the rotary motion of power source diesel engine or motor, and by this energy transferring to needs workmanship fluid end, complete corresponding work, when rotating, bent axle plays an important role, and the quality of bent axle directly affects the service behaviour of plunger pump.
Traditional plunger pump bent axle, its oil duct inner seal liner structure is comparatively complicated, comparatively inconvenience is installed, and part is comparatively fast aging, and along with the growth of service time, oil channel sealing deleterious, thus cause the lubrication effect of connecting rod bearing shell and crankshaft bearing to reduce, parts depreciation is serious, greatly reduces stability and the working life of transmission of crankshaft.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of plunger pump bent axle, effectively solve traditional plunger pump bent axle, its oil duct inner seal liner structure is comparatively complicated, install comparatively inconvenience, and part is comparatively fast aging, and along with the growth of service time, oil channel sealing deleterious, thus causing the lubrication effect of connecting rod bearing shell and crankshaft bearing to reduce, parts depreciation is serious, greatly reduces the stability of transmission of crankshaft and the defect in working life.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of plunger pump bent axle, be made up of main journal, connection axle journal and crankweb, above-mentioned main journal is provided with some crankwebs, connection axle journal is provided with between above-mentioned adjacent two crankwebs, above-mentioned each connection axle journal all offsets setting relative to the axial direction of main journal, above-mentioned each connection axle journal inside is provided with the oil duct running through the crankweb connecting axle journal and two ends thereof in the axial direction, and it is stifled that port, above-mentioned oil duct two ends is all provided with oil.
As optimization, above-mentioned two adjacent connection axle journals are that disalignment skew is arranged.
As optimization, the stifled taper oil that is set to of above-mentioned oil blocks up, and its outer surface is provided with screw thread.
As optimization, above-mentioned oil duct two ends port inner wall is all set to tapered thread, above-mentioned oil block up be threaded in oil duct two ends tapered thread on.
As optimization, above-mentioned connection axle journal is provided with the oilhole being communicated with oil duct.
As optimization, above-mentioned connection axle journal is radially vertically provided with the oilhole being communicated with oil duct.
The beneficial effects of the utility model are:
Plunger pump crankshaft structure of the present utility model is simple, tightness of oil conduit is better, and sealing configuration simple installation, effectively avoid crankshaft oil gallery affects the lubrication of connecting rod bearing shell and crankshaft bearing situation because a variety of causes causes leakage of oil, improve the reliability of transmission of crankshaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of plunger pump bent axle of the present utility model;
Fig. 2 is the cross-sectional view along axle journal direction of plunger pump bent axle of the present utility model;
In accompanying drawing, the list of parts representated by each label is as follows:
1, main journal, 2, connect axle journal, 3, crankweb, 4, oil duct, 5, oil is stifled, 7, oilhole.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment: as shown in Fig. 1 to 2, the plunger pump bent axle of the present embodiment, be made up of main journal 1, connection axle journal 2 and crankweb 3, above-mentioned main journal 1 is provided with some crankwebs 3, be provided with between above-mentioned adjacent two crankwebs 3 and connect axle journal 2, above-mentioned each connection axle journal 2 all offsets setting relative to the axial direction of main journal 1, above-mentioned each connection axle journal 2 inside is provided with the oil duct 4 running through the crankweb 3 connecting axle journal 2 and two ends thereof in the axial direction, and port, above-mentioned oil duct 4 two ends is all provided with oil stifled 5.
Above-mentioned two adjacent connection axle journals 2 are disalignment skew setting.
