Detailed description of the invention
The present invention is the method for seal closure on the sealed double-row taper roll bearing of a kind of quick fractionation two sides, in split process, any damage is not produced to the inside of two sides sealed double-row taper roll bearing, the planform of seal closure can not be destroyed, bearing after quick fractionation can reflect its original case the most really, can not affect the abrasion analysis of bearing, splits that to pull out closure assembly structure simple, easy to make, assembling is quick, uses laborsaving, alleviates the labour intensity of workman.
The large end face of two sides sealed double-row taper roll bearing is fitted with seal closure and other end is fitted with dust cover, described large end face and described other end refer to the both ends of the surface of inner ring, the right angle end that seal closure contacts with outer ring except having other shape is called large step, large end face described in inner ring is reserved and is misunderstanded each other and pass to the described large step of seal closure, reserved clearance height is given as H, and the diameter of described large step is given as 2R.
Composition graphs 2, fractionation relates to fractionation and pulls out closure assembly fast, and described fractionation is pulled out closure assembly and comprised end cap 1, pressing plate 2, gusset 3, garden base plate 4 and T-shaped axle 5.From train wheel shaft, two sides sealed double-row taper roll bearing is disassembled; described fractionation is first installed and pulls out closure assembly; be separated seal closure again; the following examples can explain the present invention in more detail; the present invention is not limited to the following examples, discloses object of the present invention and is intended to protect all changes and improvements in the scope of the invention.
Garden base plate 4 to be connected and fixed on the garden platform of T-shaped axle 5 by several soket head cap screw and together to put into inner ring endoporus.
By two fan-shaped gussets 3 by symmetric position lie in large end face described in inner ring extend to below described large step in the gap reserved, upwards mention T-shaped axle 5 and successively pressing plate 2 and two fan-shaped gussets 3 be connected and fixed on garden base plate 4 by several screw, or upwards mention T-shaped axle 5 and directly two fan-shaped gussets 3 be connected and fixed on garden base plate 4 by several screw.Described fractionation pulls out the manufacture difficulty of the higher and fan-shaped gusset of the frequency of utilization of closure assembly comparatively greatly, if do not consider that two fan-shaped gussets are directly connected and fixed on the base plate of garden preferably by several screw by these 2 to use pressing plate mainly to consider.
The support end of end cap 1 and inner groovy are held level with both hands on the cycle surface being placed on described large end face end, by T-shaped axle 5 through upper high nut equipped after end cap 1 centre bore, tightening described high nut makes T-shaped axle 5 rising cause obtaining pretension between end cap 1 and gusset 3, now end cap 1 acts on two fan-shaped gussets 3 on cycle surface downwards and upwards acts on the described large step of seal closure, the downward active force of end cap 1 equals two fan-shaped gussets 3 active force upwards and constitutes described pretension, then continuing to tighten described high nut makes two fan-shaped gussets 3 under the lifting lead of T-shaped axle 5, make seal closure depart from the spacing fastening of outer ring completely and be split fast.
End cap, pressing plate and two fan-shaped gussets can be separated and therefrom take off seal closure by the described high nut of the complete rear loosening removal of quick fractionation, described screw.Continue said method to split fast the seal closure of next two sides sealed double-row taper roll bearing.
The external diameter of garden base plate and the diameter of bore of inner ring match, shaking phenomenon is not produced when can ensure that garden base plate puts into inner ring endoporus like this, the central through hole internal diameter of garden base plate mates with the external diameter of T-shaped axle, on the base plate of garden, uniform being processed with supplies the first lap internal thread hole of described several soket head cap screw connection and encloses internal thread hole for second of described screw attachment, the centre-to-centre spacing of the second circle internal thread hole described in the centre-to-centre spacing < of described first lap internal thread hole, described first lap internal thread hole is for being connected and fixed T-shaped axle with TXing Zhou garden platform configures to enclose stepped hole corresponding, described second circle internal thread hole is used for be connected and fixed two fan-shaped gussets and pressing plate.
Platform external diameter < garden, the garden base plate external diameter of T-shaped axle, described garden platform is configured with a circle stepped hole, the centre-to-centre spacing of a described circle stepped hole equals the centre-to-centre spacing of described first lap internal thread hole, the shaft rod end threading of T-shaped axle, described externally threaded nominal diameter mates with the nominal diameter of described high nut.
Fan-shaped gusset is made up of outer impeller and interior impeller, the radius of curvature of described outer impeller is mated with described R, R described in the action < of described outer impeller, 2R described in the chord length < of described outer impeller, thickness≤described the H of described outer impeller, the described radius of interior impeller mates with the internal bore radius of inner ring, the thickness of described interior impeller equals described H+10mm, described interior impeller configures several semicircle elongated hole side by side, the width of described semicircle elongated hole equals the aperture of described second circle internal thread hole, the length of described semicircle elongated hole equals the aperture of three times of described second circle internal thread holes.
The support end external diameter of end cap is greater than outer ring external diameter, the support end internal diameter of end cap mates with outer ring external diameter, aperture >=described externally threaded the nominal diameter of end cap central bore, the maximum gauge of the minimum-depth >=seal closure of endcap support end, the several through hole of balanced configuration on end face residing for end cap central bore, several through hole except weight reduction, convenient mobile except, being connected and fixed of pressing plate and two fan-shaped gussets can also be used for.
