Abstract
The utility model discloses a double-row sealed angular contact thrust ball bearing. The double-row sealed angular contact thrust ball bearing comprises an outer ring, inner rings, rolling bodies, retaining frames and side surface sealing assemblies, wherein each side surface sealing assembly comprises a steel framework arranged in a sealing ring and a pre-tightening spring steel wire embedded outside the sealing ring; two rows of the rolling bodies are mounted between the outer ring and the first inner ring and between the outer ring and the second inner ring symmetric to the first inner ring, and correspondingly mounted in the rolling body positioning pockets of two rows of the retaining frames respectively; the side surface sealing assemblies are mounted in cylindrical holes for mounting the sealing assemblies in the two sides of the outer ring and on the outer cylindrical surfaces of the large lips of the two inner rings in a pressed way; and the sealing rings are tightly pressed on the outer cylindrical surfaces of the large lips of the inner rings through pre-tightening springs. The double-row sealed angular contact thrust ball bearing has the performance of preventing water, preventing dust and preventing residues from entering into the bearing, and is convenient to mount and dismount and long in service life; and the repair cost is reduced, lubricating greases are saved and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to biserial sealing angular contact thrust ball bearing.
Background technique
Bearing belongs to part commonly used in machinery, general part, because of the position difference of using, the not equal reason of bearing load, the kind of bearing, specification, model also is not quite similar, biserial sealing angular contact thrust ball bearing is series product in the bearing class, yet the biserial thrust angular contact bearing that uses at present is all without sealing configuration, therefore when practical application, because the impact of working environment, water often occurs, dust, enter in the bearing in dregs, make lubricant oil contaminated, therefore rolling element and in, raceway of outer ring produces early fatigue, rolling element and lasso raceway face roughness descend, and have destroyed greasy property, and bearing life is reduced, need simultaneously frequently to add lubricating grease, this means that also bearing will often change, and has so just increased cost of production, and this is in dismounting or the process of installing, both wasted manpower, material resources have increased again engineering time, have reduced manufacturing efficiency.
The model utility content
The technical problems to be solved in the utility model, provide a kind ofly convenient install, for convenience detach, long service life, reduction maintenance cost, the biserial sealing angular contact thrust ball bearing saving lubricating grease, enhance productivity.
The technological scheme that adopts is:
Biserial sealing angular contact thrust ball bearing comprises outer ring, inner ring, rolling element, retainer and side seal assembly.The cylindrical hole that black box is installed by oil groove oilhole, endoporus centre rib and the both sides of two outer raceway grooves, external diameter surface in described outer ring consists of, inner ring is made of inner cylindrical surface, outer raceway groove, large-flange and a cone cylndrical surface, rolling element is the balls tumble body, retainer is provided with pocket hole, dress rolling element location at cylindrical shell one end face and is consisted of by inside and outside cylndrical surface cylindrical shell.Described side seal assembly by establish Steel Skeleton in the seal ring, outer embedding preloading spring steel wire ring consists of.Between the raceway groove of described outer ring and symmetrically arranged two bear inner ring grooved railway two row rolling elements are installed, the two row rolling elements respectively rolling element that is contained in two row retainers of correspondence are located in the pocket hole, the side seal assembly is fitted in the both sides, outer ring and installs on the external cylindrical surface that reaches two inner ring large-flanges in the cylindrical hole of black box, and by the preloading spring steel wire ring seal ring is pressed on the external cylindrical surface of inner ring large-flange, consist of biserial sealing angular contact thrust ball bearing.
The above-mentioned side seal assembly that is fitted in the both sides, outer ring with raceway, retainer in two raceways of outer ring, rolling element, the inner ring all in the formed seal space of both sides sealing assembly, bearing has waterproof and dustproof like this, anti-dregs enters in the bearing, affects the life-span of bearing.
The utility model is reasonable in design, makes easily, and it is very convenient to remove and install, and extension device reaches more than 400% service time, and it is over half to reduce maintenance expenses, saves more than the lubricating grease twice, boosts productivity.This bearing is through particular design, and working resistance is little, and smooth running is reliable, bearing parts adopts special process, seal ring adopts the high-temperature resistant rubber manufacturing, but makes the operating temperature of bearing reach 120 degree continuous operations, is fit to very much at a high speed, the occasions such as heavy duty, impact force are large, major axis use.This bearing mainly bears axial load, also can bear certain light radial load.
Can in the place of the supporting of steel rolling Trace Roller, Continuous Casting Rolls supporting, papermaking equipment equipment etc., be used for replacing original biserial open type angular contact ball bearing and open type deep groove ball bearing.This biserial seals angular contact thrust ball bearing also applicable to machinery, mine, metallurgy, oil, chemical industry, boats and ships Submarine manufacture, all trades and professions such as hydraulic and electric engineering, processing.
