Abstract
The utility model discloses an oil discharging device of an inside-engaged gear oil pump. The oil discharging device comprises an oil discharging seat, wherein an oil discharging hole, an oil inlet hole, a locating hole and an axle hole are formed in the oil discharging seat; the oil discharging device is characterized in that an oil discharging arc-shaped groove and an oil inlet arc-shaped groove are also formed in the oil discharging seat, the oil discharging hole is communicated with the oil discharging arc-shaped groove, the oil inlet hole is communicated with the oil inlet arc-shaped groove, and the oil discharging arc-shaped groove and the oil inlet arc-shaped groove are matched with an inside-engaged gear; the oil discharging arc-shaped groove and the oil inlet arc-shaped groove of the oil discharging device are mutually symmetrical and take the shapes of arc-shaped eyebrows. Compared with the prior art, the oil discharging device has the advantages that the structural design is concise and reasonable, the arc-shaped grooves are formed in the oil discharging seat, are connected with the oil discharging hole and are matched with the inside-engaged gear so that oil is smoothly discharged in the continuous rotation of the inside-engaged gear, and high-power hydraulic mechanical movement is achieved.
Description
Technical field
The utility model relates to the discharge equipment of a kind of discharge equipment of oil pump, particularly internal gear-meshing oil pump.
Background technique
Internal gear-meshing oil pump is the mechanical motion that is exclusively used in high-power fuel feeding, inside engaged gear is fixed in oil pump, oil drainage hole is connected with inside engaged gear and is complementary, under inside engaged gear constantly rotates, hydraulic oil injects oil pocket by oil inlet hole and forms high pressure, realizes the motion of hydraulic pressure high-power machinery by oil drainage hole.The discharge equipment of the internal gear-meshing oil pump of prior art, that oil drainage hole directly is connected with inside engaged gear, hydraulic oil rotates by inside engaged gear and produces pressure, but inside engaged gear is in continuous rotation, and oil drainage hole directly is connected on inside engaged gear, can make oil drainage hole produce semi-closed state, make inside engaged gear produce oil extraction in rotation and freely do not produce the gap, in use noise is large to cause oil pump, and reduces the working efficiency of oil pump, can not meet desirable effect.
The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and a kind of discharge equipment that is exclusively used in internal gear-meshing oil pump is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of discharge equipment of internal gear-meshing oil pump, comprise the oil extraction seat, the oil extraction seat is provided with oil drainage hole, oil inlet hole, positioning hole, axis hole, it is characterized in that also being provided with on the oil extraction seat oil extraction curve bath and oil-feed curve bath, oil drainage hole is communicated with the oil extraction curve bath, oil inlet hole is communicated with the oil-feed curve bath, and oil extraction curve bath, oil-feed curve bath all are complementary with inside engaged gear.
Oil extraction curve bath described in the utility model and oil-feed curve bath are symmetrical mutually.
Oil extraction curve bath described in the utility model, oil-feed curve bath all are circular arc eyebrow shape.
The utility model compared with prior art, have the following advantages and effect: decoration structure features simple design is reasonable, have curve bath on the oil extraction seat, curve bath is connected rear and is complementary with inside engaged gear with oil drainage hole, forming inside engaged gear is that oil extraction is unobstructed in constantly rotating, and realizes the motion of hydraulic pressure high-power machinery.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the utility model embodiment's shown in Figure 1 schematic rear view.
Fig. 3 is that schematic diagram is looked on a utility model embodiment's shown in Figure 1 left side.
Fig. 4 is that the utility model embodiment is arranged on the application schematic diagram on internal gear-meshing oil pump.
Embodiment
Referring to Fig. 1～Fig. 4, the discharge equipment 8 of the utility model embodiment internal gear-meshing oil pump is provided with oil extraction seat 1, oil drainage hole 2, oil extraction curve bath 3, oil inlet hole 4, positioning hole 5, axis hole 6 and oil-feed curve bath, the oil extraction seat 1 of the present embodiment is provided with oil drainage hole 2, oil extraction curve bath 3, oil inlet hole 4, positioning hole 5, axis hole 6 and oil-feed curve bath, oil drainage hole 2 is communicated with oil extraction curve bath 3, oil inlet hole 4 is communicated with the oil-feed curve bath, and oil extraction curve bath 3, oil-feed curve bath all are complementary with inside engaged gear.
The oil extraction curve bath 3 of the present embodiment is symmetrical mutually with the oil-feed curve bath.
The oil extraction curve bath 3 of the present embodiment, oil-feed curve bath all are circular arc eyebrow shape.
The internal gear-meshing oil pump of the present embodiment in actual applications, hydraulic oil injects the rear inflow inside engaged gear of oil inlet hole 4, oil extraction curve bath 3, oil-feed curve bath are symmetrical mutually, the interior radian of oil extraction curve bath 3, oil-feed curve bath all is complementary with inside engaged gear, no matter inside engaged gear is rotated in any angle, guarantee that hydraulic oil is unobstructed in oil-feed and oil extraction, realize the motion of hydraulic pressure high-power machinery.The design of technology solved prior art because of oil-feed and oil extraction smooth the oil pump that the causes technical problem that in use noise is large, power is little, efficient is low, loss is large.
The present embodiment also is provided with oil-return groove 7, and oil-return groove 7 is prior art.
Simple deformation or the combination of every the utility model embodiment technological scheme and technical characteristics all should be thought to fall into protection domain of the present utility model.
