Abstract
The utility model discloses a plunger oil pump for lubrication, which mainly comprises a shell, a worm, an oil quantity adjusting pin, a plastic gear and a worm wheel and is characterized in that the shell is mounted on a host, and the worm is transversely arranged in a right hole of the shell; the worm is provided with an extension shaft; a shaft notch for oil pumping is formed in the head part of the extension shaft; the oil quantity adjusting pin is inserted into an upper hole of the shell; the plastic gear in the front of the shell is arranged on the worm wheel and meshed with the worm; when the host drives the plastic gear to rotate, the worm wheel and the worm are driven to rotate, the extension shaft of the worm rotates, and the shaft notch for oil pumping of the extension shaft pumps in the lubricating oil from an inlet; and the oil quantity adjusting pin changes the position of the shaft notch of the extension shaft of the worm at an oil inlet to adjust the oil charge quantity of an oil pump. With a small volume, the plunger oil pump disclosed by the utility model can be applied to a hand-push mower; and the plastic gear of the oil pump is driven by the power of the mower to start the oil pump to work, and lubricating oil is automatically added to a power head and a cutting head of the mower.
Description
Technical field
The utility model relates to machinery, relates in particular to a kind of plunger-type fuel pump.
Background technique
Lubricated be applied in the lubrication system of many unit heads with plunger-type fuel pump, but the shortcoming of existing oil pump being, is not can proper functioning in all positions, the few or fuel feeding not at the working position fuel feeding that has, thereby its Applicable scope is restricted.
The model utility content
Technical problem to be solved in the utility model provides a kind of lubricated plunger-type fuel pump of using, and volume is little, and fuel feeding is smooth and easy.
The utility model is achieved through the following technical solutions: a kind of lubricated plunger-type fuel pump of using, mainly comprise housing, worm screw, fuel-flow control pin, plastic gear, worm gear, described housing has lubricating oil inlet, outlet, three mounting holes and four holes that accessory is installed, it is characterized in that: be mounted on the main frame at housing, horizontal in its hole, right side worm screw is housed, described worm screw has outrigger shaft, be with fuel-displaced control spring on the described outrigger shaft, the two ends dress of fuel-displaced control spring is wanted packing ring, is provided with the axle breach of oil pumping usefulness at the head of outrigger shaft; Be positioned at the oil pumping usefulness the axle breach the position, be attached at housing main frame one side be up and down oil-feed and oil outlet (not drawing on the figure); Rubber plug is equipped with in outer end worm screw; On the housing left side aluminium plug is housed; Insert the fuel-flow control pin in the housing upper surface hole, be with Returnning spring, packing ring, O type circle on the bar of fuel-flow control pin and vertically pass housing, overlap packing ring, O type circle again and be inserted with pin, pin is with fuel-flow control lock position; Plastic gear is equipped with in described housing front, and plastic gear is contained on the worm gear, and worm gear and supporting locating stud, fiber cushion are contained in the housing, with worm meshing.
When main frame drives plastic gear and rotates, drive worm gear, worm screw is rotated, the worm screw outrigger shaft rotates, the axle breach of its oil pumping usefulness lubricant oil from the import suction.
Described fuel-flow control pin intermediate cylindrical is eccentric, is cooperated with fuel-displaced control spring by the fuel-flow control pin, rotates and regulates pin, can control worm screw outrigger shaft move left and right, changes the axle breach of worm screw outrigger shaft in the position of filler opening, regulates the volume read-out of oil pump.
The beneficial effects of the utility model are: because volume is little, can be applied in hand-push type mower, utilize the plastic gear of the power drive oil pump of mowing machine to start oil pump work, mowing machine unit head and cutter head are carried out automatic lubricating oil filling.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is a kind of lubricated plunger-type fuel pump structural representation of using of the utility model.
Embodiment
As shown in Figure 1, a kind of lubricated plunger-type fuel pump of using, mainly comprise housing 1, worm screw 2, fuel-flow control pin 3, plastic gear 4, worm gear 5, described housing 1 has lubricating oil inlet, outlet, three mounting holes and four holes that accessory is installed, it is characterized in that: be mounted on the main frame at housing 1, horizontal in its hole, right side worm screw 2 be housed, described worm screw 2 has outrigger shaft 2.1, be with fuel-displaced control spring 2.2 on the described outrigger shaft 2.1, the two ends dress of fuel-displaced control spring 2.2 is wanted packing ring 2.3; Be provided with the axle breach 2.4 of oil pumping usefulness at the head of outrigger shaft 2.1; Be positioned at the position of the axle breach 2.4 of oil pumping usefulness, be attached at housing 1 main frame one side oil-feed and oil outlet (figure does not draw) arranged up and down; In the outer end of worm screw 2 rubber plug 6 is housed; On housing 1 left side aluminium plug 7 is housed; In housing 1 upper surface hole, insert fuel-flow control pin 3, be with Returnning spring 3.1, packing ring 3.2, O type circle 3.3 on the bar of fuel-flow control pin 3 and vertically pass housing 1, overlap packing ring 3.4, O type circle 3.5 again and be inserted with pin 3.6, pin 3.6 is with fuel-flow control pin 3 lock-bits; Plastic gear 4 is equipped with in described housing 1 front, and plastic gear 4 is contained on the worm gear 5, and worm gear 5 is contained in the housing 1 with supporting locating stud 5.1, fiber cushion 5.2, with worm screw 2 engagements.
When main frame drives plastic gear 4 and rotates, drive worm gear 5, worm screw 2 is rotated, worm screw 2 outrigger shafts 2.1 rotate, the axle breach 2.3 of its oil pumping usefulness lubricant oil from the import suction.
Described fuel-flow control pin 3 intermediate cylindricals are eccentric, cooperated with fuel-displaced control spring 2.2 by fuel-flow control pin 3, rotate and regulate pin 3, can control worm screw 2 outrigger shafts 2.1 move left and right, change the breach 2.4 of worm screw 2 outrigger shafts 2.1 in the position of filler opening, regulate the volume read-out of oil pump.
