Description
Technical field
The present invention relates to and press interior ball selflubricating fuel-injection pump, be applicable to the surperficial oil injecting lubricating of gear and threaded pipe and plain tube, belong to lubrication sciemtifec and technical sphere.
Background technique
Gear in modern power transmission in occupation of maximum accounting, but the lubrication of gear is all utilize gear to infiltrate in a large amount of lubricant oil, so both wasted a large amount of lubricant oil, transmission system is made again to seem very " dirty ", the present invention is the mode of the interior ball oil impregnate of extruding touching utilizing gear, make gear obtain lubricant oil, so not only consume lubricants capacity fewer, but also untapped lubricant oil can not be polluted.
Summary of the invention
The object of this invention is to provide a kind of by mutually ball displacement oil impregnate and make two gears be meshed mutually lubricate press interior ball selflubricating fuel-injection pump in extruding touching between gear.
Press interior ball selflubricating fuel-injection pump, comprise the interior ball in a fuel-injection pump and fuel-injection pump, piston holder, spring, fuel-injection pump bottom plug; It is characterized in that:
1, the centre of fuel-injection pump roof has a circular open to be hole on fuel-injection pump, on fuel-injection pump, the inside edge in hole is an oblique sphere, fuel-injection pump is provided with an interior ball immediately below hole, interior ball is circular ganoid hardware ball, on fuel-injection pump, the interior skew back sphere in hole and the outer spherical surface of interior ball match, the piston holder of a piston shape is installed immediately below interior ball, the upper-end surface of piston holder is a recessed smooth sphere, the recessed smooth sphere radius of piston holder and the radius of interior ball match, interior ball is made to be placed on the recessed smooth sphere of piston holder, and make interior ball can on the recessed smooth sphere of piston holder rotary rolling, little 0.5mm ~ the 2mm of fuel-injection pump internal diameter radius that the radius ratio of piston holder is smooth, piston holder can be done piston type and move up and down in smooth fuel-injection pump, a spring is installed with immediately below piston holder, the lower end of spring and the upper plane of fuel-injection pump bottom plug are fixedly linked, fuel-injection pump bottom plug is fixedly mounted on the position near fuel-injection pump under shed, there are a bottom plug center hole in the central authorities of fuel-injection pump bottom plug, bottom plug center hole is connected with the oil inlet hole of gear, spring in the holder of such fuel-injection pump bottom plug, latch bracket piston holder, interior ball in the recessed smooth sphere holder of piston holder, the top sphere of interior ball is made to withstand on the inner side surface in hole on fuel-injection pump, the spring-force driven dual of spring is utilized to make the stressed inner side surface withstanding on hole on fuel-injection pump of interior ball, and seal laminating mutually with the inner side surface inclined-plane in hole on fuel-injection pump, on fuel-injection pump, the radius in hole is less than interior ball, make the top sphere of interior ball stretch out hole on fuel-injection pump and exceed fuel-injection pump roof distance for 0.5mm ~ 5mm, the lubricant oil of coming in from the oil inlet hole of gear enters into fuel-injection pump inner chamber by bottom plug center hole, and along gap between piston holder and fuel-injection pump inwall move up enter into piston holder upper-side area and interior ball around, when interior ball is not subject to external force extruding touching, the upper sphere of interior ball is fitted with the interior skew back sphere in hole on fuel-injection pump and is sealed mutually, therefore, lubricant oil around interior ball now can not ooze out from hole fuel-injection pump, when interior ball is subject to external force extruding touching, the spring-force driven dual that interior ball overcomes spring moves down, interior ball is made to exceed the upper-end surface of fuel-injection pump roof and concordant with the upper-end surface of fuel-injection pump roof by the top sphere being squeezed to interior ball downwards, now, the upper end sphere of interior ball is separated with skew back sphere in hole on fuel-injection pump, thus the lubricant oil around interior ball is oozed out from hole fuel-injection pump.
2, fuel-injection pump installed by gear: a gear in a pair gear is installed the lubricating requirement that two fuel-injection pumps just can meet these two gears, fuel-injection pump is arranged on the between cog paddy position between two gear teeth of gear, two fuel-injection pumps are arranged on the asymmetric position of gear, because the radius of two gears is different, the number of teeth is not etc., so two of asymmetric installation fuel-injection pumps just can reach the requirement of mutually lubricating after two gears meshing rotate a few, fuel-injection pump adopts freezing to install, after freezing by fuel-injection pump, in the straight hole of the between cog paddy between the gear tooth being directly installed on normal temperature, be warming up to after normal temperature heat expansion until fuel-injection pump, fuel-injection pump is made to be fixed in the straight hole of between cog paddy firmly, the oil inlet pipe of fuel-injection pump is arranged on the side of gear, and be connected with total oil inlet pipe, total oil inlet pipe is arranged on central gear axis, and it is parallel with central gear axis, when two gears are meshed in rotary course, the gear teeth meshing of a gear is to when being provided with the between cog paddy of fuel-injection pump, interior ball on the fuel-injection pump of between cog paddy is squeezed to interior ball upper end sphere by the gear teeth is concordant with the between cog paddy face of fuel-injection pump, now, because lubricant oil is with pressure or the effect of gear rotary centrifugal force, lubricant oil around interior ball is oozed out and the gear teeth of ball in lubrication extrusion from hole fuel-injection pump, be arranged on the between cog paddy of gear asymmetrically owing to there being two fuel-injection pumps, so, after two gears meshing rotate a few, interior ball on the fuel-injection pump that all gear teeth of the gear not installing fuel-injection pump just can be made to be squeezed to be arranged between cog paddy, the gear teeth being simultaneously expressed to interior ball are also just stained with oil lubrication, in rotation, the gear teeth be engaged with are made to be stained with oil lubrication with other gear teeth meshing of gear of installing fuel-injection pump by the gear teeth being stained with oil lubrication again, like this after engagement rotates a few, installation fuel-injection pump can be made and all gear teeth of two gears not installing fuel-injection pump to be all stained with oil lubrication, this mode can reduce the use amount of lubricant oil relatively largely, also lubricant oil can be made before not entering oilgear can not to be subject to the pollution of gear simultaneously, and when the lubricants capacity on the gear teeth is more, because centrifugal action will be got rid of a part, particularly contaminated lubricant oil is more easily got rid of because its attached power of work reduces.
3, on threaded pipe or plain tube, fuel-injection pump is installed: multiple fuel-injection pump can be installed on threaded pipe, fuel-injection pump is arranged on the position, the lowest point between externally threaded two screw threads of threaded pipe, position, the lowest point between the fuel-injection pump roof outer side surface of multiple fuel-injection pump with two screw threads of threaded pipe is concordant, when sleeve in rotary moving on threaded pipe or sleeve pipe are expressed to ball in fuel-injection pump, the lubricant oil around interior ball will ooze out from hole fuel-injection pump and the sleeve of ball or sleeve pipe internal thread in lubrication extrusion; Multiple fuel-injection pump can be installed on plain tube, the fuel-injection pump roof outer side surface of multiple fuel-injection pump is concordant with the outer wall of plain tube, when sleeve in rotary moving on plain tube or sleeve pipe are expressed to ball in fuel-injection pump, the lubricant oil around interior ball will ooze out from hole fuel-injection pump and the sleeve of ball or casing tube internal hole wall in lubrication extrusion.
