A kind of as can be known taper roller bearing with a retainer from US-A-4425011, this retainer are designed to realize by oil lubricant better lubricated.But this known bearing is not suitable for grease lubrication.
The solution that the purpose of this invention is to provide a kind of these problems.
It is because bearing is grease lubrication, keeps hack lever to have a flat internal surface that can bond an oil layer on it that this purpose is achieved.
In normal course of operation, in the operation process of bearing, grease can flow in group of rollers, is splashed then.Because centrifugal force, when new grease entered in this group of rollers, grease was slightly along keeping hack lever to drive.
Generally, forming one " balance " layer below each keeps hack lever, should " balance " layer be quite stable for specific speed and fatness.
This oil layer is particularly suitable for guaranteeing the correct lubricated of bearing.Grease produces lubrication effect by oozing out the oil that is contained in wherein, and this oil will directly arrive close position, i.e. roller and the corresponding hack lever that keeps.Can carry out the conveying of oil by capillarity and under steam condition.
According to a preferred embodiment, each internal surface that keeps hack lever from the minor diameter spacer ring to major diameter spacer ring diagonally extending, thereby impel grease lubricant under action of centrifugal force, to flow to the major diameter spacer ring.
The present invention relates to dissimilar taper roller bearings; But especially, bearing can comprise two groups of taper rollers, and every group of roller is spaced apart by a corresponding retainer, and the minor diameter spacer ring of described retainer is oppositely arranged, and surrounds an intermediate space, and wherein this intermediate space is equipped with grease lubricant.
In operation process, the grease in the intermediate space can little by little flow towards two row rollers.Grease can enter each row roller by the slit between inner bearing ring or spacer ring and the minor diameter spacer ring.It also can enter by the slit between retainer and the outer bearing ring.Subsequently, arrive the roller end and arrive the maintenance hack lever then.
Therefore according to a preferred embodiment, this bearing can comprise by separated two inner bearing rings of an intermediate annular element, described two race rings have a raceway that is trapped among between a minor diameter convex shoulder and the major diameter convex shoulder respectively, its medium-small diameter spacer ring is around the minor diameter convex shoulder, thus impel grease lubricant from middle spatial flow to keeping on the hack lever.
For similar purpose, this minor diameter spacer ring also can be around to the small part mesosphere.
Outer bearing ring can be the integral type outer bearing ring that comprises two raceways.But this outer bearing ring can comprise two separated adjacent bearing coil components.
The motion of retainer when spacer ring also is used for stable the use near convex shoulder.
The minor diameter spacer ring can inwardly stretch out with respect to the inner surface radial direction that keeps hack lever; The major diameter spacer ring can be concordant with the internal surface that keeps hack lever.The minor diameter spacer ring also can axially reach outside the inner bearing ring end face towards intermediate space.The major diameter spacer ring also can inwardly stretch out with respect to the inner surface radial direction that keeps hack lever.
Cooperate with the correct of roller in order to ensure retainer, each keeps hack lever to have two jaws that deviate from the internal surface of described maintenance hack lever.Each jaw can have an extension part, and this extension part extends above the minor diameter spacer ring and is attached thereto.In this way, between jaw/maintenance hack lever and described race ring, obtained being connected of firm and a rigidity.
In addition, at least one seal ring can be connected with this outer bearing ring.
With reference to the accompanying drawings the present invention is further described.
