Embodiment
below in conjunction with accompanying drawing and specific embodiment, technological scheme of the present invention is further elaborated.
see a kind of electromagnetic-permanent magnetic drive-type rolling bearing multi-point lubricating pump shown in Fig. 2, Fig. 3, for carrying out feed lubrication to rolling bearing.This lubricant pump comprises electromagnetic-permanent magnetic driving mechanism, lays respectively at the pump head body 5 of these electromagnetic-permanent magnetic driving mechanism both sides.
see shown in Fig. 2 and Fig. 3, electromagnetic-permanent magnetic driving mechanism comprise be fixedly installed hollow shape yoke 1, be housed in DC coil 2 in yoke 1 inner chamber regularly, be located in armature 3 in DC coil 2 regularly, lay respectively at the axial both sides of armature 3 and can two sliding assembly 4 moving vertically of armature 3 relatively.Each sliding assembly 4 includes slide block 41, is fixedly arranged on slide block 41 inner end to close on the permanent magnet 42 of armature 3, the wherein shaft axis of the slide block 41 and shaft axis of armature 3 is parallel to each other or conllinear extends, slide block 41 can slide along the relative armature 3 of Pivot Point Center line.Herein, the shaft axis of armature 3 extends in left-right direction, and two groups of sliding assembly 4 are located at the left and right sides of armature 3 respectively.
the inner end of slide block 41 offers accepting groove, and namely permanent magnet 42 is embedded regularly in this accepting groove.The outer end, both sides of yoke 1 all has the perforation 11 that can penetrate slidably for permanent magnet 42 correspondence, the inner end of permanent magnet 42 penetrates in this perforation 11 with may correspond to, and the diameter of slide block 41 is greater than the aperture of perforation 11, when sliding assembly 4 slides towards armature 3, slide block 41 can be kept out on the outer end of yoke 1 spacing to the slip of sliding assembly 4 to be formed like this.
on the sliding assembly 4 of armature 3 left and right sides, permanent magnet 42 is arranged on the contrary near the end pole of armature 3, that is, if the permanent magnet in left side 42 is near the end of armature 3, that is the right part of left side permanent magnet 42 is N pole, then the permanent magnet 42 on right side is near the end of armature 3, that is the left part of right side permanent magnet 42 is then S pole.Like this, when DC coil 2 is energized, armature 3 produces magnetic, and the magnetic pole at armature 3 two ends is contrary, thus makes to produce repulsion between the permanent magnet 42 of both sides and armature 3 simultaneously, and then the relative armature 3 of the sliding assembly 4 ordering about both sides outwards slides.
shown in Fig. 2, Fig. 3, pump head body 5 comprise be fixedly installed and there is the cylinder body 51 of oil pocket 51a, pump plunger 52 that opposing cylinder 51 stretches vertically, the shaft axis of pump plunger 52 parallels with the shaft axis of armature 3, and the external part of pump plunger 52 is fixedly attached in the outboard end of slide block 41.Be provided with oil exit pipe 6 between cylinder body 51 and the rolling bearing 20 treating feed lubrication, oil exit pipe 6 is provided with discharge opeing one-way valve 7, and this discharge opeing one-way valve 7 is arranged to rolling bearing 20 unilaterally connected by oil pocket 51a; This lubricant pump also comprises fuel tank 10, and be also provided with fuel supply line 8 between this fuel tank 10 and cylinder body 51, fuel supply line 8 is provided with imbibition one-way valve 9, and this imbibition one-way valve 9 is arranged to oil pocket 51a unilaterally connected by fuel tank 10.
particularly, in the present embodiment, the same side of armature 3 is provided with multiple pump head body 5, thus feed lubrication can be carried out to multiple rolling bearing 20.On the same side of armature 3, the cylinder body 51 of all pump head bodies 5 is wholely set; On all pump head bodies 5, the external part of pump plunger 52 is all fixedly attached on the slide block 41 of this side, herein, the cross section of slide block 41 is rounded, external part compartment of terrain distribution in the end face outside of slide block 41 of all pump plungers 52, wherein, the shaft axis of pump plunger 52 that all pump plunger 52 king-rod footpaths are maximum and the shaft axis conllinear of slide block 41 extend, as shown in Figure 4.
like this, under original state, when DC coil 2 is not energized, because armature 3 is ferromagnetic metals, produce attraction force between permanent magnet 42 and armature 3, sliding assembly 4, near armature 3, forms negative pressure in the oil pocket 51a of pump head body 5 and from fuel tank 10, sucks lubricant oil by imbibition one-way valve 9; Then, DC coil 2 is energized and generation current, armature 3 produces magnetic, the magnetic at armature 3 two ends should be contrary with the magnetic pole of both sides permanent magnet 42 respectively, even the permanent magnet 42 in left side is N pole near the end of armature 3, the permanent magnet 42 on right side is S pole near the end of armature 3, and so armature 3 left end is N pole, right-hand member is S pole.Like this, all repulsion is produced between the permanent magnet 42 of armature 3 and both sides.Between armature 3 and both sides permanent magnet 42 repulsion effect under, the sliding assembly 4 of both sides all slides towards the direction away from armature 3, namely the sliding assembly 4 of both sides all outwards slides, this makes piston rod 52 slide towards cylinder body 51, and piston rod 52 fluid extruded in oil pocket 51a makes the lubricant oil in oil pocket 51a arrive rolling bearing 20 place to be lubricated by discharge opeing one-way valve 7.Obtain after lubricant oil until rolling bearing 20 place, DC coil 2 power-off, between armature 3 and both sides permanent magnet 42 gravitation effect under, the sliding assembly 4 of both sides all slides towards armature 3 and realizes resetting, automatically realize backhaul, the fluid in fuel tank 10 enters to be entered in pump head body 5 by imbibition one-way valve 9 again.After certain interval of time, DC coil 2 is energized again, make pump head body 5 again by discharge opeing one-way valve 7 to rolling bearing 20 feed lubrication.So repeatedly, just achieve the fuel feeding of the duration impulse formula to rolling bearing 20, under rolling bearing 20 place so just can be made to be in good oil lubrication environment all the time, can also save lubricants capacity, the machine avoiding fluid too much to cause pollutes simultaneously.
to sum up, by adopting electromagnetic-permanent magnetic driving mechanism to drive multiple pump head body 5 simultaneously in the present invention, the sliding assembly 4 wherein only adopting an armature 3 just can order about both sides slides simultaneously and orders about pump head body 5 working in reciprocating mode, pump head body 5 is made constantly to complete oil suction and force feed work under the cooperation of imbibition one-way valve 9 with discharge opeing one-way valve 7, thus the pulsed fuel feeding realized multiple rolling bearing 20, under making rolling bearing 20 place be in good oil lubrication environment all the time, can also save lubricants capacity, the machine avoiding fluid too much to cause pollutes simultaneously.This electromagnetic-permanent magnetic drive-type rolling bearing multi point lubricating pump structure very simple, easily manufactured, with low cost, is applicable to the rolling bearing lubrication under many occasions.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
