With continued reference to Fig. 1, close and offer perforation on the relative both sides housing wall of housing 11.The two ends of multidiameter 10 are respectively
Penetrate perforation and connect closing housing 11.Multidiameter 10 connects closing housing 11 by sealing connecting component after passing through perforation, permissible
It is easy to high magnetic absorption rod 9 is installed in closing housing, and easy to disassemble, be conducive to the impurity of high magnetic absorption rod 9 to clear up
And change.
Sealing connecting component at least includes sealing-plug 12.This sealing-plug 12 is used for being tightly connected the one end of multidiameter 10
Position is naturally it is also possible to be used for being tightly connected the two-end part of multidiameter 10.In the present embodiment, sealing-plug 12 sealing is used for penetrating
Multidiameter 10 has the perforation of ladder position one end.One side multidiameter 10 is inserted into wearing of the side housing wall of closing housing 11
Kong Shang, another aspect sealing-plug 12 is fixedly connected the side housing wall of this perforation.Spiral shell can be passed through between sealing-plug 12 and housing wall
Fitting screws tight fixation.
Preferably, penetrating the perforation with ladder position one end of multidiameter 10, that is, the perforation of connection sealing-plug 12,
Flare openings including integrally connected and straight hole portion.Multidiameter 10 has ladder position one end and penetrates straight hole from flare openings
Portion is simultaneously fixed in straight hole portion.When connecting due to high magnetic absorption mechanism, need to extend in closing housing 11, right with boring a hole
Connect, thus flare openings are conducive to the rapid-aligning of multidiameter 10, and straight hole portion then can avoid multidiameter 10 in perforation
Rock, play fixation.
Referring to Fig. 1, sealing connecting component includes:End cover 2, exterior seal ring 4, guide ring 5, inner seal ring 6.Sealed end
Lid 2, exterior seal ring 4, guide ring 5, inner seal ring 6 are arranged at multidiameter 10 and do not have at the perforation of ladder position one end, when
So, the other end of multidiameter 10 can also arrange these parts.
Inner ring position (inside ring) and the inner seal ring 6 of guide ring 5 are connected, and the outer shroud position of guide ring 5 is (outside ring
Side) it is connected with exterior seal ring 4, realize better seal effect.Referring to Fig. 3, exterior seal ring 4 preferably sets on inside edge
There is exterior seal ring inner groove 41 inwardly, be tightly connected for mating with the outer ring portion of guide ring 5.Referring to Fig. 4, inner seal ring
6 are preferably provided with inner seal ring outer groove 61 outwardly on outer ledge, for mating sealing with the annular inner portion of guide ring 5 even
Connect.Guide ring 5 side, the preferably inner side of inner seal ring 6, the one end not having ladder position with multidiameter 10 is connected, and realizes
The fixation at this end of multidiameter 10 in the mounted state.
Referring to Fig. 1, close to be used on housing 11 penetrating multidiameter 10 not having and have inside the perforation of ladder position one end
Back-up ring.Exterior seal ring 4, guide ring 5, inner seal ring 6 are inwardly sealed the gear being pressed on this perforation outside perforation by end cover 2
On circle, realize the sealing of this perforation, end cover 2 is detachably connected closing housing 11, for example, can pass through end cover bolt 1
Be spirally connected seal casinghousing 11, is additionally provided with pad 3 so that connecting portion uniform force between end cover 2 and closing housing 11, close
Envelope is more preferably.
Setting exterior seal ring 4, guide ring 5, these discrete parts of inner seal ring 6, so that high magnetic absorption rod 9 Hes
The dismounting of positioning component is more convenient, and is all connected with sealing ring on guide ring 5 inner and outer ring, and sealing reaches most preferably, outside
Portion is sealedly connected by end cover 1 again, strengthens sealing property further, prevents internal lubrication oil seepage, even if repeatedly
Dismount high magnetic absorption rod, still ensure that high sealing performance.
Preferably, exterior seal ring 4 and inner seal ring 6 are high elastic rubber material, due to having high resiliency, exterior seal ring 4
With inner seal ring 6 diametrically can elastic telescopic, thus size can be adjusted according to flexible situation so that guide ring 5 and outer
The sealing structure that sealing ring 4, inner seal ring 6 are monolithically fabricated can be installed in the perforation of different pore size, can avoid in perforation
Size has the problem that during deviation, sealing effectiveness is deteriorated, and prevents from producing permeability phenomenon in work.
Preferably, referring to Fig. 1 and Fig. 2, the cross section of high magnetic absorption rod 9 is in X-type, when decelerator in the course of the work,
The metal impurities such as its abrasion iron filings and lubricating oil are blended in together, and when lubricating oil drops in X-shaped high magnetic absorption rod, X-type cuts
Face region effectively expands the adsorption storage area of metal impurities.In the mounted state, a groove of X-type is towards engaging piece
Position, can adsorb the metal cast with storage effectively, and the lubricating oil being difficult to be flowed washes away.
Further, in the case that the cross section of high magnetic absorption rod 9 is in X-type, the fork of X-type is exactly protruding parts,
Being preferably directed bar 8 is two guide posts, is axially disposed within the middle both sides position of X-type high magnetic absorption rod 9, in order to guide high magnetic
Property adsorbing bar 9 enter multidiameter 10, and make high magnetic absorption rod 9 circumferentially positioned, guide post 8 is supported by closing housing 11.Guiding
Ring 5, guide post 8 material are nylon or high-strength engineering plastic, and Portable durable is difficult to get rusty.
In one embodiment, the decelerator of self-cleaning metal impurities can also include high magnetic absorption bar type dipstick (figure
Not shown in).High magnetic absorption bar type dipstick sealing is plugged on closing housing 11, in order to detect the lubrication in closing housing 11
Oily liquid level, can point out fluid too high or too low, and the chi body of high magnetic absorption bar type dipstick is made using high magnetic material,
Thus helping the metal impurities in adsorpting lubrication oil, it is to avoid be again introduced into site of engagement and cause to damage.
Although the present invention is open as above with preferred embodiment, it is not for limiting claim, any this area
Technical staff without departing from the spirit and scope of the present invention, can make possible variation and modification, therefore the present invention
Protection domain should be defined by the scope that the claims in the present invention are defined.
