Description
Technical field
The utility model relates to the industrial sewing machine field, relates to a kind of Sewing machines gear pump in particular.
Background technology
Present Sewing machines is in the process that forms stitching, and Sewing machines plays a part to carry, reclaim needlework and tighten up stitching.In order to reduce the load of Sewing machines, can adopt oil pump that Sewing machines is carried out fuel feeding and oil return.
Existing sewing machine generally adopts the oil pump of plunger type.It mainly is made up of oil pump body, installing plate, filtration square, plunger, spring, fuel feed pump and oil return pipe.The oil pump structure of this plunger type is complicated, and manufacturing cost is high, also can't realize the function of low speed oil return and fuel feeding.And the recirculating oil quantity of this Sewing machines is low, even run up, recirculating oil quantity is also few.Run up at Sewing machines and to carry out under the situation of sewing work, when oil pump feed was too many, the recirculating oil quantity of plunger oil pump was very little, and oil return completely is clean, and the eedle position can leakage of oil.When sewing fabric, be prone to be stained with greasy dirt, cause the very big loss of manufacturer.
The utility model content
The utility model provides a kind of novel Sewing machines gear pump to the weak point that above-mentioned technology exists.
To achieve these goals, the utility model provides a kind of Sewing machines gear pump, comprises installing plate, the pump housing, master gear, pinion, first supporting plate, fuel feeding impeller and second supporting plate; Said installing plate flexibly connects the pump housing; Said master gear is installed on the pump housing, and said pinion is meshed with master gear, and said first supporting plate is located at the below of master gear and pinion; And be connected on the pump housing; Said fuel feeding impeller is installed on the master gear through first supporting plate, and said second supporting plate is located at the below of fuel feeding impeller, and is connected on the pump housing.
In some embodiments, also comprise square, said square is installed on second supporting plate.
In some embodiments; The said pump housing is provided with fuel oil supply nozzle, following fuel oil supply nozzle, oil return nozzle and cavity; Be fixed with first cylinder on the said master gear, this first cylinder is installed in the cavity of the pump housing, and said fuel oil supply nozzle, following fuel oil supply nozzle and the oil return nozzle gone up is connected with fuel feed pump and oil return pipe respectively.
In some embodiments, said first cylinder is the hexagon cylinder, and its center is provided with the hexagon groove.
In some embodiments, said fuel feeding impeller is provided with second cylinder, and this second cylinder is the hexagon cylinder, and said hexagon cylinder is installed in the hexagon groove of first cylinder.
What the utility model adopted is the gear structure pattern, simple in structure.The fuel feeding process is the engaged transmission through master gear and pinion, drives the fuel feeding wheel rotation, and lubricating oil is delivered to fuel oil supply nozzle and following fuel oil supply nozzle, through fuel feed pump lubricating oil is delivered to each position of Sewing machines again.The oil return process is the engaged transmission through master gear and pinion, make between the cavity of first cylinder and the pump housing and form the vacuum space, the lubricating oil in the oil return pipe through oil return nozzle by vacuum suction to this vacuum space, thereby realize the oil return of Sewing machines.The utility model low cost of manufacture, easy to install and use, can low speed fuel feeding and oil return.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, a kind of Sewing machines gear pump comprises: installing plate 1, the pump housing 2, master gear 3, pinion 4, first supporting plate 5, fuel feeding impeller 6 and second supporting plate 7.Also comprise square 8.Installing plate 1 can be connected on the pump housing 2 through screw.The pump housing 2 is provided with fuel oil supply nozzle 201, following fuel oil supply nozzle 202, oil return nozzle 203 and cavity 204.Last fuel oil supply nozzle 201, fuel oil supply nozzle 202 and oil return nozzle 203 are connected with fuel feed pump and oil return pipe respectively down.
Be fixed with first cylinder 301 on the master gear 3, this first cylinder 301 is installed in the cavity 204 of the pump housing 2.First cylinder 301 can be the hexagon posts body, and its center is provided with the hexagon groove.Pinion 4 is meshed with master gear 3.First supporting plate 5 is located at the below of master gear 3 and pinion 4, and is connected on the pump housing 2 through trip bolt.
What the utility model adopted is the gear structure pattern, simple in structure.The fuel feeding process is the engaged transmission through master gear 3 and pinion 4, drives fuel feeding impeller 6 and rotates, and lubricating oil is delivered to fuel oil supply nozzle 201 and following fuel oil supply nozzle 202, through fuel feed pump lubricating oil is delivered to each position of Sewing machines again.The oil return process is the engaged transmission through master gear 3 and pinion 4; Make between the cavity 204 of first cylinder 301 and the pump housing 2 and form the vacuum space; Lubricating oil in the oil return pipe through oil return nozzle 203 by vacuum suction to this vacuum space, thereby realize the oil return of Sewing machines.
The torsion in the utility model when work is less, and the not fragile pump housing, master gear and pinion have prolonged service life of Sewing machines gear pump.The recirculating oil quantity of the utility model is bigger than the recirculating oil quantity of Sewing machines oil pump, has guaranteed the oil return of machine biglyyer, has guaranteed the clean and tidy of Sewing machines.And the utility model is simple in structure, and manufacturing cost is lower, uses installation more convenient.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from utility model creation design; Can also make other distortion or improvement, these all belong to the protection domain of the utility model.
