Abstract
The utility model provides a manual quantitative grease lubricating device, comprising a pressurizing screw rod, an end cover nut, an oil containing cylinder, a piston, a rear cover, a fixing nut, a sealing ring, an adjusting screw, a pressing spring, a positioning steel ball and a rolling path steel ball hand wheel. The manual quantitative grease lubricating device adopts a trapezoidal thread pair and a rolling ball-rolling path structure; great thrust can be generated by a screw rod through easily rotating an end cover with an inner thread so as to extrude grease out; when the end cover is rotated for one ring, the extruded grease is quantitative; and rotating times are determined according to specific lubricating requirements (wherein the positioning steel ball is reset by the spring to realize a counting effect), so that the quantitative lubrication is achieved. The manual quantitative grease lubricating device has the advantages that oil is quantitatively supplied; the structure is simple and the manufacturing is convenient; and the lubrication in any position can be achieved.
Description
Affiliated technical field
The utility model belongs to general lubricator, and being applicable to provides quantitative lubricating fat to various machinery equipments.
Background technique
In order to guarantee the needs of machinery equipment service behaviour, the lubricated link that is absolutely necessary.Add the oiling agent that needs and not only can reduce friction between rubbing surface, alleviate wearing and tearing, the protection part does not suffer corrosion, and can also play the effect of radiating and cooling.
At present at home in the grease lubrication fuel-servicing equipment, hand-pushing grease gun and cap-rotating type grease are to use to get the widest lubricator, they can satisfy oily needs substantially, but the delivery volume of lubricating grease can not scientific quantitative analysis, can only be by virtue of experience, sense organ is familiar with to estimate, can not reach the lubricated of arbitrary position.The machinery equipment that the has lubricating grease of heatproof more than 250 ℃ of must annotating, and this lubricating grease is expensive, quantitatively use can be saved cost of production.
Summary of the invention
In order to guarantee the service behaviour that machinery equipment is good and to save production cost, the utility model proposes a kind of Manual quantitative lubricator.
The technical solution of the utility model makes such realization: it comprises pressurization screw rod, end cap nut, oil containing drum, piston, bonnet, set screw nut, seal ring, adjusting screw, holddown spring, positioning ball, raceway steel ball and handwheel.Pressurization screw rod and end cap nut adopt trapezoidal thread to connect, one end of pressurization screw rod is equipped with handwheel, the other end connects with piston by set screw nut, oil containing drum and bonnet adopt scyewed joint, the end cap nut forms to roll by the raceway steel ball with oil containing drum and contacts, oil containing drum and piston form sliding contact by seal ring, and the compacted spring of positioning ball and adjusting screw are positioned in the positioning hole on the end cap nut.Adopt the secondary and ball road structure of this trapezoidal thread, just can make screw mandrel produce very large thrust when easily rotating tapped end cap, extrude grease, whenever the grease that extrudes that turns around is quantitative, determines that according to concrete lubricated needs number of revolution (positioning ball plays the numeration effect with spring reset) has namely reached quantitative lubricating.
The utility model has the advantages that: 1. quantitative fuel feeding; 2. simple in structure, it is convenient to make; 3. can reach the lubricated of arbitrary position.
Description of drawings
Fig. 1 is quantitative manual lubricator structural representation.
Fig. 2 is the connecting mode schematic representation of oil outlet and extraneous flexible pipe.
Among the figure: 1. pressurization screw rod, 2. end cap nut, 3. oil containing drum, 4. piston, 5. bonnet, 6. set screw nut, 7. seal ring, 8. adjusting screw, 9. holddown spring, 10. positioning ball, 11. raceway steel balls, 12. handwheels.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, pressurization screw rod 1 and end cap nut 2 adopt trapezoidal thread to connect, one end of pressurization screw rod 1 is equipped with handwheel 12, the other end connects with piston 4 by set screw nut 6, oil containing drum 3 and bonnet 5 adopt scyewed joint, end cap nut 2 and oil containing drum 3 form to roll by raceway steel ball 11 and contacts, and oil containing drum 3 and piston 4 be by seal ring 7 formation sliding contacts, and positioning ball 10 compacted springs 9 and adjusting screw 8 are positioned in the positioning hole on the end cap nut 2.
Lubricating grease is stored in the oil containing drum 3, thereby rotary end cover nut 2 pressurization screw rods 1 and piston 4 produce downward axial motion and extrude lubricating grease, positioning ball 10 breaks away from the positioning hole of end cap nut 2 in the rotation process, positioning ball 10 resets to again the positioning hole of end cap nut 2 because of holddown spring 9 after rotating a week, thereby plays the numeration effect.End cap nut 2 whenever turns around and extrudes the lubricating grease of fixed amount, determines according to actual needs number of revolutions, has satisfied the needs of quantitative refueling.
Fig. 2 is the connecting mode schematic representation of oil outlet and extraneous flexible pipe.According to the difference of lubricating point position, can according to actual needs at the supporting pipe joint of screwing on the bonnet 5 of conical inner screw thread, can reach the lubricated of arbitrary position behind the hose.
