Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of associated sealing arrangement for bearings for noria tensioning roller.
Background technique
Noria tensioning roller is usually located at bucket lifting drive end unit, is also called tail wheel, and its effect has 2 points, the first, tensioning adhesive tape, the second, the position that adjustable adhesive tape runs, and prevents rubber belt from deviating, avoids lift bucket and belt and bucket elevator casing to bump against.In order to practical function two, roller shaft and bearing degree is needed to have a certain amount of adjustable drift angle.The setting type of roller bearing seats has two kinds, one is external, namely bearing seat is outside afterbody casing, this structure is adopted by most of domestic bucket elevator producer, because tailing axle needs up-down adjustment, this joint configuration formula overall tightness is bad, there will be a large amount of material and spills from bucket elevator afterbody.Another kind of form is built-in bearing structure, and this joint structure is positioned at device interior due to bearing, and integral sealing effect is good, also Just because of this, requires that bearing can keep long-acting lubrication and sealing.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, designs and a kind ofly has excellent sealing effect and there will not be leakage of oil to leak the associated sealing arrangement for bearings of bucket elevator tensioning roller of material phenomenon.
For achieving the above object, design a kind of associated sealing arrangement for bearings for noria tensioning roller, comprise axle, bearing support, retaining ring, sealing slip ring, O-ring seals, set screw, it is characterized in that: the left side of described bearing support is connected with axle, the axle right-hand member being positioned at bearing support is arranged with bearing support sealing slip ring, and be positioned on the axle on the left of bearing support sealing slip ring and be arranged with bearing seal slip ring, the axle be positioned on the left of bearing seal slip ring is provided with the first O-ring seals; Described bearing seal slip ring is made up of metal slip and the second O-ring seals, and the surface cover of described metal slip outer ring has circle second O-ring seals; Described bearing support sealing slip ring is made up of another metal slip and the 3rd O-ring seals, and the surface cover of another metal slip outer ring described has a circle the 3rd O-ring seals.
The outer surface of described metal slip and another metal slip offers a circle groove respectively.
Described second O-ring seals and the 3rd O-ring seals are set in the groove of metal slip and another metal slip respectively.
The outside of a described O V-shaped ring is provided with retaining ring, and described retaining ring is fixed on axle by set screw.
The right flank of described bearing seal slip ring outer ring and bearing support seals the left surface close contact of slip ring outer ring and the surface roughness of surface of contact is little.
Described bearing seal slip ring is located between retaining ring and axle.
The utility model compared with the existing technology, adopt the Combination application of sealing slip ring and O-ring seals, suffered by O-ring seals, pre-extrusion is out of shape the reaction force produced, when can ensure that tail-gear spindle and bearing support have certain drift angle, two sealing slip rings still can fit tightly, and have extraordinary sealing effect; There will not be oil leakage phenomenon, within general more than 1 year, change a lubricant oil.Power generating ratio number of times, easy to use and maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that bearing seal slip ring of the present utility model and bearing support seal slip ring.
See Fig. 1 ~ Fig. 2, wherein, 1 is bearing support, 2 is retaining rings, and 3 is bearing seal slip rings, and 4 is first O-ring seals, 5 is set screws, 6 is axles, and 7 is bearing support sealing slip rings, and 8 is grooves, 3-1 is metal slip, 3-2 is the second O-ring seals, and 7-1 is another metal slip, and 7-2 is the 3rd O-ring seals.
Embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the left side of described bearing support 1 is connected with axle 6, axle 6 right-hand member being positioned at bearing support 1 is arranged with bearing support sealing slip ring 7, and be positioned on the axle 6 on the left of bearing support sealing slip ring 7 and be arranged with bearing seal slip ring 3, the axle 6 be positioned on the left of bearing seal slip ring 3 is provided with the first O-ring seals 4; The outside of a described O V-shaped ring 4 is provided with retaining ring 2, and described retaining ring 2 is fixed on axle 6 by set screw 5.Described bearing seal slip ring 3 is located between retaining ring 2 and axle 6.
As shown in Figure 2, described bearing seal slip ring 3 is made up of metal slip 3-1 and the second O-ring seals 3-2, and the surface cover of described metal slip 3-1 outer ring has a circle second O-ring seals 3-2; Described bearing support sealing slip ring 7 is made up of another metal slip 7-1 and the 3rd O-ring seals 7-2, and the surface cover of another metal slip 7-1 outer ring described has a circle the 3rd O-ring seals 7-2.The outer surface of described metal slip 3-1 and another metal slip 7-1 offers a circle groove 8 respectively.Described second O-ring seals 3-2 and the 3rd O-ring seals 7-2 is set in the groove 8 of metal slip 3-1 and another metal slip 7-1 respectively.The right flank of described bearing seal slip ring 3 outer ring and bearing support seals the left surface close contact of slip ring 7 outer ring and the surface roughness of surface of contact is little.
When the utility model uses, retaining ring 2 is fixed on axle 6 by set screw 5,0 shape seal ring 4 realizes the sealing between retaining ring 2 and axle 6, bearing seal slip ring 3 is made up of metal slip 3-1 and the second O-ring seals 3-2, bearing support sealing slip ring 7 is made up of another metal slip 7-1 and the 3rd O-ring seals 7-2, fit tightly between bearing seal slip ring 3 and bearing support sealing slip ring 7, and the face that contacts with each other of metal slip 3-1 and another metal slip 7-1 adopts minute surface to grind pin processes, there is very little surface roughness.When bearing seal slip ring 3 and bearing support sealing slip ring 7 are fixed on after in bearing support 1 and retaining ring 2, due to fitted position setting with ensure bearing seal slip ring 3 and bearing support sealing slip ring 7 in the second O-ring seals 3-2 and the 3rd O-ring seals 7-2 be squeezed produce distortion, metal slip 3-1 and another metal slip 7-1, under the second O-ring seals 3-2 and the 3rd O-ring seals 7-2 is out of shape the reaction force produced, keeps close contact.When the tailing axle of axle 6 rotates, retaining ring 2, O-ring seals 4, set screw 5, second O-ring seals 3-2, metal slip 3-1 rotate with axle, and the 3rd O-ring seals 7-2 and another metal slip 7-1 and bearing support 1 maintain static.Because very little surface roughness and lubricant oil add the ultra-thin oil film of one deck of rear formation, ensure that metal slip 3-1 and another metal slip 7-1 can freely relatively rotate, but lubricant oil from the outside seepage of surface of contact, can not reach good sealing effect.
