Abstract
A double-raw self-aligning tapered roller bearing consists of an outer ring, inner rings, rolling elements, holders, a self-aligning sleeve and an inner ring spacer. The outer ring is composed of a double conical surface outer raceway, an external diameter of an outer spherical surface and an oil groove and an oil hole located on the external diameter surface of the outer spherical surface. The self-aligning sleeve comprises an outer spherical raceway which is matched with the external diameter of the outer spherical surface of the outer ring, the oil groove and the oil hole located on the external diameter surface and a groove installed on the outer ring. The self-aligning sleeve is sleeved with the outer ring, double-raw rolling elements are installed between the outer ring and the two symmetrically arranged inner rings, and the double-raw rolling elements are respectively installed in the rolling element positioning window orifice of the double-raw holders. Each of the inner rings is composed of an inner cylindrical surface and an outer cylindrical surface, and the inner ring spacer is installed between the two symmetrically arranged inner rings and plays a role of adjusting the bearing clearance, thus a double-raw self-aligning tapered roller bearing is formed. The double-raw self-aligning tapered roller bearing has the advantages of being easy to assemble, convenient to disassemble, long in service life, low in maintaining cost and high in production efficiency.
Description
Technical field
The utility model relates to bearing, particularly relates to a kind of double-row self-aligning tapered roller 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, the double-row self-aligning tapered roller bearing is series product in the bearing class, yet the double-row conical bearing that uses at present is all without the aligning structure, therefore there is not aligning function, when using, rolling element and in, the raceway of outer ring two ends produce edge stress, therefore rolling element and in, the raceway of outer ring two ends produce early fatigue, make lubricant oil contaminated, rolling element and the scratch of lasso raceway face are large, have destroyed greasy property, and bearing life is reduced, this means that also bearing will often change, this must run into great difficulty in the process of dismounting or installation, 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 double-row self-aligning tapered roller bearing of enhancing productivity.
The technological scheme that adopts is:
A kind of double-row self-aligning tapered roller bearing comprises outer ring, inner ring, rolling element, retainer, aligning cover and cone spacer.The outer ring is made of the oil groove oilhole of the outer raceway of Double-conical-surface, outer spherical surface external diameter and outer spherical surface external diameter surface, inner ring is made of inner cylindrical surface, male cone (strobilus masculinus) raceway, the large-flange of guide rolls and the little rib of a gear roller, rolling element is the cone rolling element, and retainer is made of dress rolling element fenestra on frame type conical surface and the conical surface.Described aligning cover is made of oil groove oilhole and the dress outer ring groove of the external spherical surface raceway that is complementary with outer ring outer spherical surface external diameter, external diameter surface, aligning cover and outer ring suit, between outer ring and symmetrically arranged two inner rings 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 fenestra.Described cone spacer is made of inside and outside cylndrical surface, and cone spacer is contained in middle the plaing of inner ring of two symmetries and regulates the bearing clearance effect, so just forms the double-row self-aligning tapered roller 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 200% service time, and it is over half to reduce maintenance expenses, boosts productivity.This bearing is through particular design, and working resistance is little, and smooth running is reliable, and the bearing parts operating temperature reaches 120 and spends, and is fit to very much high speed, heavily loaded, the occasions uses such as impact force is large, major axis.This bearing mainly bears radial load, also can bear certain axial load.Can in places such as the supporting of steel rolling Trace Roller, Continuous Casting Rolls supporting, papermaking equipment equipment, be used for replacing original biserial conical bearing and Biserial cylindrical roller bearing.This bearing is 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.
