Detailed description of the invention
Below according to accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
According to Fig. 1 to Fig. 6, the axial composite cylindrical roller bearing in a kind of footpath described in the present embodiment, include journal bearing assembly and axial bearing assemblies；Described journal bearing assembly includes outer ring 1, inner ring 2 and rolls the radial roller group 3 being arranged between outer ring and inner ring, and described radial roller group is arranged on a radial direction retainer 4.
Described outer ring inwall forms outer roller surface, and one end of described outer ring forms outer ring retaining wall 10, and the other end of described outer ring forms the conical surface 12, and the cone angle of the described conical surface is 22-24 °, and the conical surface 12 enters outer ring raceway face 13 smoothly in order to guide radially set of rollers..Described outer ring inwall and retaining wall junction, outer ring form outer ring oil groove 14.
Described inner ring 2 outer wall forms interior roller surface 21, and described inner ring forms inner ring retaining wall 20 away from one end of outer ring retaining wall, and described interior ring outer wall and inner ring retaining wall junction form inner ring oil groove 22.
It is concordant with the inner surface of described outer ring retaining wall that described inner ring differs from one end end face of inner ring retaining wall.
Described axial bearing assemblies includes the axial set of rollers 8 that blowout patche 6, seat ring and rolling are connected between blowout patche and seat ring, and described axial set of rollers is arranged on an axial cage 9；
Described blowout patche and described inner ring differ from one end of inner ring retaining wall and offset.
Described radial direction retainer 4 circumferentially forms multiple pocket hole 41 equably, is radially tie-beam 40 between biphase adjacent pocket hole on retainer, and radial direction retainer periphery is positioned at the position of each described tie-beam and forms groove 42；The end position being positioned at tie-beam on described radial direction retainer forms oil storage tank 43, and described tie-beam forms two contact heads 44 towards each sidewall in pocket hole.Described radial direction retainer adopts the processing of glass-fiber-reinforced polyamide 46 material integrated injection molding.It is four point-contact types that described pocket hole contacts with radial roller group, and four contact head 44 actually four segment salient points, set of rollers is maintained in retainer pocket hole by four contact heads；Described groove 42 is in order to oil storage and increases retainer installation elasticity, is beneficial to the dismounting of radial roller, and the weight of retainer decreases, and has saved cost, has embodied economic benefit.Described radial direction retainer is processed by PA46-GF25 (glass-fiber-reinforced polyamide 46) material integrated injection molding, is just producing processing and bearing assembling is all very convenient, and efficiency is higher.PA46-GF30 material can improve bearing heat resisting temperature.
Described outer ring outer wall forms O groove, and described O groove is arranged with O RunddichtringO.The phenomenon causing outer ring to skid because bearing outer ring is different from sheathing material harmomegathus at bearing operation adstante febre can be prevented to occur, improve the life-span, reduce failure rate of machinery.
When the axial composite cylindrical roller bearing in this footpath assembles, first O 5 is enclosed within outer ring, in many pocket holes being manually loaded radially retainer 4 of radial roller group 3, then inner ring is inserted in the roller set bore diameter installing retainer, making set of rollers be placed on interior roller surface 21, inner ring has the one of inner ring retaining wall to face down to keep flat, afterwards the outer ring conical surface is enclosed within down inner ring with the molectron of set of rollers outside, make radial roller group external diameter be external in outer ring raceway face 13, measure the end-play value of this journal bearing.Then, by in many pocket holes being manually loaded axial cage 9 of axial set of rollers 8, making each axial roller and put up a combination with axially retaining, placed without the laminating of inner ring retaining wall end face with inner ring 2 blowout patche outer face, axial set of rollers is placed between blowout patche inner face and seat ring inner face.For preventing from scattering, all parts are held together by available nylon binding strap from inside to outside.So far, the assembling of the axial composite cylindrical in a set of footpath roller bearing is complete.
