Abstract
The utility model relates to an antirust corrosion-resistant bearing and a corresponding bearing component. The conventional bearing cannot meet the requirements of aquaculture, particularly mariculture. The antirust corrosion-resistant bearing comprises a bearing body, wherein the bearing body is totally made of plastics and has a ball table shape; and a through hole is formed in the center of the bearing body. An antirust corrosion-resistant bearing component comprises a bearing block and a bearing, wherein the bearing block is totally made of plastics; the bearing is the bearing provided by the utility model; a cylindrical hole is formed on the bearing block and has a diameter of more than or equal to a spherical diameter of the bearing; two opposite tile bulges are formed in the cylindrical hole; the space between the two tile bulges is greater than the thickness of the ball table of the bearing; opposite inner surfaces of the tile bulges are machined into a spherical inner cavity; and the spherical inner cavity corresponds to a spherical surface of the bearing. The antirust corrosion-resistant bearing and the corresponding bearing component have the advantages of simple structure, high rust resistance, high corrosion resistance and convenience for installation and are widely applied to the fields of aquaculture, shipbuilding and the like.
Description
Technical field
The utility model relates to a kind of antirust corrosion resistant bearing and corresponding bearing unit.
Background technique
The aerator that aquaculture, particularly mariculture industry are used, aerator often with water/contact with sea water, its bearing machine oil of should not too much annotating again, antirust corrosion resistant performance requires harshness.
Existing sliding bearing is many to be made up of two blocks of brasses, and brasses is seawater corrosion resistance not, can't be used for aquaculture.
Existing steel rolling bearing comprises parts such as outer ring, inner ring, rolling element (ball or roller) and retainer; Except that retainer; All need want temper fire, even stainless steel can sex change when adopting stainless steel material matter temper fire) also can't adapt to the sea-farming requirement, need frequent change, maintenance.
Existing plastic bearing also comprises parts such as outer ring, inner ring, rolling element (ball or roller) and retainer, and the plastic bearing of this structure has been ignored plastic material and steel qualitative difference, bad mechanical strength, and pressurized is yielding.
More than three kinds of bearings frequent filling lubricant oil when using.
Aquaculture, particularly during sea-farming, be to guarantee water quality, the bearing lubricant oil of can only annotating on a small quantity, continually.Water quality requirement is extra high, at all can not lubricating oil filling, and can only the frequent change bearing.
The model utility content
The technical problem that the utility model will solve is the above-mentioned defective that how to overcome existing technology, and a kind of antirust corrosion resistant bearing and corresponding bearing unit are provided.
For solving the problems of the technologies described above, this antirust corrosion resistant bearing comprises bearing body, and this bearing body is made of plastics fully, is billiard table shape, and the center has through hole.Bearing body selects for use duroplasts to process, and preferentially selecting molecular weight for use is 1,000 ten thousand ultra-high molecular weight polyethylene.Bearing body running in a day 24 hours in seawater of using ultrahigh molecular weight polyethylene to do, continuous operation 8 months, its center through-hole wall wearing and tearing are no more than 0.05 millimeter.
The billiard table structure is adopted in so design, mixes bearing support, can play the effect of aligning; Parts such as outer ring, inner ring, rolling element (ball or roller) and retainer all are reduced to parts, and structural strength is high, and antirust corrosion resistant performance is good.
As optimization, the hole wall of said through hole extends into annular protrusion respectively up and down.Material is saved in so design.
As optimization, also be provided with a stop screw on the said bearing body.So design is convenient to bearing body is fixed in the bearing support.
The antirust corrosion resistant bearing unit of the utility model; Comprise bearing support and bearing, said bearing support is made of plastics fully, it is characterized in that: said bearing is an aforementioned bearings; Said bearing support has cylindrical hole; The spherical diameter of its diameter >=said bearing body, it is protruding to be provided with two relative tile fragments in this cylindrical hole, and the spacing of the two protruding two ends of tile fragment ports is greater than the billiard table height of bearing body; The protruding opposite inner face of tile fragment is processed into the sphere inner chamber, and this sphere inner chamber is corresponding with the sphere of said bearing body.
As optimization, it comprises two limited rings, is equipped with fastening screw trip bolt on two limited rings, is separately positioned on the bearing body both sides, is enclosed within on the adapted axle with bearing body.So design can prevent that bearing is along the axle play.
It is superior that this antirust corrosion resistant bearing and corresponding bearing unit have simple in structure, antirust corrosion resistant performance, and convenient installation adaptable across fields such as aquaculture, shipbuildings, is particularly suitable for mariculture industry and uses.
Description of drawings
Below in conjunction with accompanying drawing this antirust corrosion resistant bearing and corresponding bearing unit are described further:
Fig. 1 is the structural representation of this antirust corrosion resistant bearing;
Fig. 2 is the structural representation of this antirust corrosion resistant bearing unit;
