Abstract
The utility model relates to a sealing of the shaft and the end cap, in particular to a magnetic sealing which is applicable for the shaft and the end cap of the common speed reducer. The utility model solves the problem puzzling for several years that the speed reducer leaks the oil when running. The technical solving proposal of the utility model is that a magnetic sealing applicable for the speed reducer comprises a gear shaft of the speed reducer, wherein the gear shaft is sleeved with a bearing, the bearing is arranged inside a bearing base, an output shaft end is provided with a shaft-face side end cap, and the end cap is fixed on the bearing base through a bolt. The utility model is characterized in that the circumference of the shaft-face side end cap close to the gear shaft is perforated and equipped with a plurality of strong magnets, and the interval between the strong magnets is homogeneously disposed and has 4 to 6 strong magnets. The positions of the inner side and the outer side of the shaft-face side end cap which correspond to the strong magnets are separately provided with an inner sealing disc and an outer sealing disc. The inner sealing disc is a plane labyrinth sealing disc, the outer sealing disc is a ring sealing disc which is equipped with plumbago, and the contacting surfaces between the inner sealing disc and the outer sealing disc, and the gear shaft are all provided with O-shaped sealing rings. The utility model is mainly applicable for the shaft and the end cap of the common speed reducer.
Description
Technical field:
The utility model relates to a kind of axle and end bracket enclosed, particularly a kind of magnetic seal that is applicable to common deceleration arbor and end caps.
Background technique:
Cold rolling mill finishing subsidiary factory is the finishing operation of cold-strip steel retrofit finished product packing.Finishing subsidiary factory often has oil droplet to drop on the band surface of steel plate during driving lift cargo, causes flat cold-rolled sheet to pollute, and produces quality and descends.With reference to Fig. 1, the sealing of deceleration arbor and end caps comprises speed reducer tooth axle 1, socket bearing 2 on the tooth axle 1, bearing 2 is installed in the bearing support 3, be equipped with axial plane side end cap 4 at the output axle head, end cap 4 is equipped with reinforced seal by being bolted on the bearing support 3 between axial plane side end cap 4 and output shaft, because of the input of braking action of vehicle machine, output shaft axle envelope seepage, once used two pass rubber skeleton sealing instead, to grind groove on axle promptly ineffective when sealing lip, and working life is short.Existing magnetic seal costs an arm and a leg, and the complex structure heaviness is limited by rigging position, change the related components structure, so be starved of a kind of Sealing that need not too much change of component structural and favorable sealing property.
Summary of the invention:
The purpose of this utility model provides the magnetic seal that is applicable to common deceleration arbor and end caps, solve and perplex a braking action of vehicle machine seepage oil difficult problem for many years, its technical solution is: a kind of magnetic seal that is applicable to speed reducer, comprise speed reducer tooth axle, socket bearing on the tooth axle, Bearing Installation is in bearing support, be equipped with the axial plane side end cap at the output axle head, end cap is by being bolted on the bearing support, it is characterized in that, install a plurality of strong magnets at the axial plane side end cap additional near punching on the circumference at tooth axle place, evenly arrange at interval between the strong magnets, be 4-6.Seal disc and external sealed dish in end cap inboard and outer survey in axle side is installed additional respectively corresponding to the strong magnets place.
Interior seal disc is a plane labyrinth seal dish, and the external sealed dish is for installing the carbon ring seal disc additional, all adds O-ring seals at interior seal disc and external sealed dish and tooth axle surface of contact.
The beneficial effects of the utility model are: owing to installed strong magnets additional on end cap, make that inside and outside seal disc adhesive is more firm, but strong magnets is difficult for above 6, many dress strong magnets, then end cap both sides sealing dish can not rotate with axle, and the O-ring seals of seal disc avoids machine oil to leak outside with the axle friction.Seal disc outer rim and labyrinth tank car system groove sealing in the casing, oil seals to circumferential outer edge during rotation, does not adopt carbon ring here in order to avoid pollute oil, and end cap outside seal disc installs carbon ring additional, plays secondary seal and dustproof effect.The utility model utilizes the original end cap of speed reducer, installs inside and outside seal disc additional, and simple in structure effectively physical life reduced amount of maintenance more than 2 years, is applicable to that all kinds of speed reducers of important events use.
Description of drawings:
Fig. 1 is existing deceleration arbor and end bracket enclosed structural representation
Fig. 2 is the utility model structural representation
Among the figure: 1-tooth axle, 2-bearing, 3-bearing support, 4-axial plane side end cap, 5-strong magnets, seal disc in the 6-, 7-external sealed dish, 8-carbon ring, 9-O shape seal ring.
Specific implementation method:
With reference to Fig. 2, a kind of magnetic seal that is applicable to speed reducer, comprise speed reducer tooth axle 1, socket bearing 2 on the tooth axle 1, bearing 2 is installed in the bearing support 3, is equipped with axial plane side end cap 4 at the output axle head, and end cap 4 is by being bolted on the bearing support 3, install 6 strong magnets 5 at the axial plane side end cap additional near punching on the circumference at tooth axle place, evenly arrange at interval between the strong magnets.Seal disc 6 and external sealed dish 7 in end cap inboard and outer survey in axle side is installed additional respectively corresponding to the strong magnets place.Interior seal disc is a plane labyrinth seal dish, and the external sealed dish is for installing carbon ring 8 seal discs additional, all adds O-ring seals 8 at interior seal disc and external sealed dish and tooth axle surface of contact.The strong magnets φ 10mm of buying, long 10mm, end cap install seal disc place two sides finish turning to thickness 10mm, roughness 0.8,60 ° of uniform φ 10mm 6 holes interlace, each strong magnets 5 hits heart dotting punch at 6 bore edges, is convenient to better fixed magnet, on the interior seal disc 6 dress axles, assembling end cap 4 and external sealed dish 7, adjust end cap 4 and paste mutually with interior seal disc 6 bit copper positions, seal arrangement integral body pushes the fastening end cap screw of casing bearing hole, and this skeleton rubber hermetic resistance is slightly greatly normal during the setting stick moving axis.Normally move working life greater than 2 years, the diameter of axle is wearing and tearing not, thoroughly solve leakage of oil, and processing cost is low, and is simple in structure, are applicable to that all kinds of speed reducers use.
