Description
Technical field
The utility model relates to a kind of oil pump parts, specifically hydraulic gear pump lateral plate.
Background technique
Gear pump is a kind of broad-spectrum power plant; Gear pump forms two enclosed spaces by two gears, the pump housing and front and rear covers, relies on the change of the swept volume formed between pumping cylinder and engaging gear and move carry liquid or make it supercharging.When pinion rotation, the volume in the space of the side that is out of gear is large from little change, forms vacuum, is sucked by liquid; Liquid from diminishing greatly, and is clamp-oned in pipeline and is gone by the volume in the space of gears meshing side; Suction chamber and discharge side rely on the line of contact of two gears to separate.The pressure of the exhaust port of gear pump depends on the size pumping place's resistance completely.
The structures shape of gear pump self its to exist " entrap phenomenon, namely in the course of the work, the gear teeth of original pair of meshing are not yet thrown off, and a pair gear teeth below enter engagement; Between two gear teeth to engagement, so just produce the volume (being called pocketed oil district) of a choke-out, the fluid stayed between these two pairs of gear teeth is trapped in this volume closed.The existence in pocketed oil district, increases mechanical vibration, wearing and tearing and noise, also reduces working life.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiency in above-mentioned background technology, a kind of gear pump side-plank of modified node method is provided, this gear pump side-plank can be accelerated pocketed oil district high pressure oil and release, and there is better vibration damping, Noise Reduction, reduce the dynamic alternate load of pump shaft, to ensure that equipment normally effectively works.
The technological scheme that the utility model proposes is:
With a Novel hydraulic gear pump side plate for compensating groove, comprise the plate-like body being manufactured with two gear shaft holes, described two gear shaft holes keep at a certain distance away the layout and the axis of two axis holes is parallel to each other; It is characterized in that: the working surface of plate-like body is manufactured with communication two gear shaft holes and the waveform oil groove corresponding with gear pump pocketed oil district, with oilgear axle; The working surface of described plate-like body also sets up certain depth and the U-shaped compensating groove corresponding with gear pump pocketed oil district, to reduce vibration and noise; The edges at two ends of described U-shaped compensating groove is communicated with the external world by the bottom side edge edge of side plate.
Described certain depth is 2-4mm.
The width of described U-shaped compensating groove is 10-15mm, and width is 1-2mm, is highly 10-15mm.
The width of described waveform oil groove is 1-2mm, and the degree of depth is 2-4mm.
The beneficial effects of the utility model are:
Set waveform oil groove corresponds to gear pump pocketed oil district, and during work, the pressure oil in pocketed oil district just successfully can enter two gear shaft holes, effectively lubricates two gear shafts, reduces pump shaft wearing and tearing, reduces noise; U-shaped compensating groove corresponds to gear pump pocketed oil district, and during work, the pressure oil in pocketed oil district just can flow (intake side entering gear pump) fast outward, thus reduces mechanical vibration, reduces noise; Waveform oil groove and U-shaped compensating groove produce certain damping to the pressure oil run in oil groove again simultaneously, prevent because the oil pressure in pocketed oil district declines excessive and occur the problem that gear pump output oil pressure declines.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Embodiment
The hydraulic gear pump lateral plate of band compensating groove as shown in the figure, comprise the plate-like body A being manufactured with two gear shaft holes 3 (driving gear axis hole and driven gear axis hole), described two gear shaft holes are mutually isolated and keep at a certain distance away, and the axis of two gear shaft holes is parallel to each other layout.These structures are all identical with existing hydraulic gear pump lateral plate.
Improvement of the present utility model, it is the waveform oil groove 1 being manufactured with communication two gear shaft holes on the working surface (this working surface facing to driving gear end face and driven gear end face, and carries out sliding friction with driving gear end face and driven gear end face) of described plate-like body; This waveform oil groove is corresponding with gear pump pocketed oil district, thus the gear pump oil in gear pump pocketed oil district can be caused oilgear axis hole, for the lubrication of gear shaft, reduces pump shaft wearing and tearing, reduces noise.As recommendation, the width of described waveform oil groove is 1-2mm, and the degree of depth is 2-4mm.
The working surface of described plate-like body is also set up the U-shaped compensating groove 2 of certain depth, this compensating groove is also corresponding with gear pump pocketed oil district, and the edges at two ends of compensating groove is communicated with the external world by the bottom side edge edge of side plate; During work, the pressure oil in gear pump pocketed oil district (gear pump oil) is just discharged into the outside of plate-like body fast by the groove of U-shaped compensating groove, enter the intake side of gear pump; Because the incompressible pressure oil in pocketed oil district can partly discharge, significantly reduce vibration and the mechanicalness noise of gear pump, reduce the dynamic alternate load of pump shaft; Simultaneously by selecting the size in U-shaped compensating groove cross section, the flow of pilot pressure oil, prevents gear pump output oil pressure decline problem.
As recommendation, the certain depth of described compensating groove is 2-4mm; Or determine as required.The width b of described U-shaped compensating groove is 10-15mm, and width a is 1-2mm, and height h is 10-15mm; Or determine as required.
