Description

Portable electric dry-oil pump

The utility model is the utensil for various machinery lubricating point filling drier oils.

According to the interrelated data retrieval, also there be not the hand held, electric dry oil pump identical at present with the utility model structure.In industrial production and general machinery equipment transmission system, except that adopting centralized lubrication and pneumatic lubricating utensil, all adopt hand gun filling drier oil at present.The deficiency that adopts hand gun to refuel is: use manually and refuel, it is slow to add speed oil, and labor intensity is big, adds shortage of oil sometimes and causes the lubricating component oil starvation and damage mechanical device.

The purpose of this utility model is, overcomes the deficiency of hand gun in using, and provides a kind of and can substitute the model utility oiling utensil that oil gun uses fully.

The utility model is achieved through the following technical solutions.The hand held, electric dry oil pump is made up of motor, retarder, oil pump, oil tank, portable mechanism and base plate.Retarder, oil pump and portable mechanism are contained on the base plate, motor be contained on the casing of retarder and and input shaft of speed reducer connect with pair of engaged gears, the piston rod of clutch end of retarder (axis of guide) and oil pump links (contact), and oil tank is contained on the oil pump body.Portable mechanism is made up of side plate, carriage and handgrip, and electric switch is loaded on the carriage.The casing of retarder is made by aluminum alloy, and driving gear is arranged in the speed reducer, driven gear, worm screw, worm gear, worm-wheel shaft, cam and the axis of guide.Driving gear is loaded on the motor output shaft, and driven gear is loaded on the worm screw, the engagement of driving gear and driven gear, dress worm gear and cam, worm gear and worm meshing on the worm-wheel shaft, the wheel rim of cam and the output terminal of retarder (axis of guide) link (contact).Oil pump is made up of cylinder body, piston rod, ring washer, Returnning spring, one-way valve, fittings body.Piston rod is loaded in the cylinder body, and back-up ring is contained on the piston rod, and multiple resilience spring is loaded between the back-up ring and cylinder body on the piston rod, and one-way valve is loaded on the oil cylinder output terminal, and fittings body is loaded on the one-way valve end.On cylinder body, have oil-sucking hole with the end of piston rod work original state, oil-sucking hole communicates with oil tank.Oil tank is made up of staving, case lid, piston, Sealing, pull bar, pressure spring.Staving is an Al-alloy parts, and Sealing is contained on the piston, and case lid and staving connect, pull bar and piston spiral marking connection, and pressure spring is loaded between piston and the case lid.On the first half Cylinder of pull bar, a groove is arranged.The biside plate of portable mechanism is screwed in the base plate both sides.Fill it up with drier oil in the oil tank, connect power supply and get final product work.

The utility model is compared with the oil gun of present use, uses motor as power source, and it is fast, laborsaving to add speed oil, can overcome because of adding shortage of oil to cause mechanical oil starvation to damage.Have compact structure, in light weight equally, can carry, characteristics easy to use.

Accompanying drawing is a structural representation of the present utility model.Fig. 1 is the plan view of hand held, electric dry oil pump, and Fig. 2 is the worm-wheel shaft axial section, and Fig. 3 is a portable mechanism left view.Among the figure:

The 1--motor; The 2--driving gear; The 3--driven gear; The 4--worm screw;

The 5--base plate; The 6--worm-wheel shaft; The 7--worm gear; The 8--axis of guide; The 9--cam;

The 10--back-up ring; 11 Returnning springs; The 12--piston rod; The 13--cylinder body;

The 14--one-way valve; The 15--Sealing; The 16--piston; The 17--pressure spring;
