Embodiment
As shown in Figures 1 to 4, a kind of bearing fixing device disclosed in the utility model, include bearing seat 1 and mounting body 2, mounting body 2 is fixed on bearing seat 1, mounting body 2 has support bottom surface 21, mounting body 2 is provided with some mounting holes 22, bearing saddle bore 11 is provided with in bearing seat 1, the axial forward end mouth of bearing saddle bore 11 is provided with the spacing back-up ring 3 in front end, the axial rearward end mouth of bearing saddle bore 11 is provided with the spacing back-up ring 4 in rear end, described mounting body 2 is arranged on bearing seat 1 axial rearward end, the bearing saddle bore 11 of corresponding described bearing seat 1 and the support bottom surface 21 of mounting body 2 are in vertical, in mounting body 2, mounting hole 22 distributes ringwise.
In this specific embodiment, the spacing back-up ring in described front end 3 is shaping with bearing seat 1 integrated punching, and the spacing back-up ring 4 in described rear end is inlaid in the bearing saddle bore 11 axial rearward end mouth of bearing seat 1, and mounting body 2 is one-body molded with bearing seat 1.Under this structural design, on the one hand, bearing seat, the spacing back-up ring in front end and mounting body can adopt overall impact briquetting, technique is simple, easy to process, shaping product is light and intensity good, and on the other hand, the spacing back-up ring in rear end is inlaid in the axial rearward end mouth of bearing seat, formed when avoiding being assembled on equipment bearing Mounting device and interfere, compact structure, simultaneously bearing seat rear port correspondence integrated mounting body with it, this segment thickness is large, intensity is large, be convenient to the assembling of the spacing back-up ring in rear end, ensure its working strength, ensure reliable operation; The more important thing is, bearing Mounting device is when installing and using, and it needs to bear certain outwards axial force, namely the spacing back-up ring in front end is subject to the axial force of bearing comparatively greatly, and the spacing back-up ring in front end adopts with bearing seat one-body molded, and working strength is larger, more reliable, avoid collapsing lid phenomenon.Certainly as the technological scheme that the utility model is feasible, the spacing back-up ring in front end can be adopted detachably to be arranged on bearing seat through fastening piece, the spacing back-up ring in rear end and bearing seat one-body molded, but under this structure, bearing seat thickness is restricted, corresponding linkage structure is set, there is difficulty of processing large, complex structure, and reliability is low, in using process, the spacing back-up ring axially loaded in front end is large, there is the potential safety hazard collapsing lid; Certainly also can adopt the spacing back-up ring in front end through welding or riveting on bearing seat, the spacing back-up ring in rear end is one-body molded with bearing seat, and because bearing seat thickness is restricted, intensity is low, and this is arranged down, and the potential safety hazard of lid is collapsed in same existence; Therefore the utility model preferentially adopts the structural design of this specific embodiment.
For ensureing the reliable of use, the spacing back-up ring of the spacing back-up ring in front end 3 and rear end 4 is the narrow limit that coordinate spacing with the outer ring of bearing and designs, the inner ring of such bearing is free to rotate, ensure that bearing running is smooth and easy, the mesopore pore size of the spacing back-up ring in rear end 4 is less than the spacing back-up ring 3 in front end, and the inward flange of the spacing back-up ring 4 in rear end crosses bearing outer ring.The spacing back-up ring in rear end is larger to the supporting surface of rolling bearing, and the spacing back-up ring in rear end is later stage assembling, and under this structure, the spacing back-up ring in rear end is more reliable to the support limit of rolling bearing, and rolling bearing assembling is solid and reliable, good operating stability.
Wherein, the assembling mode of the spacing back-up ring in rear end can have various structures form: as shown in Figure 2, is provided with jump-ring slot 12 in the axial rearward end mouth of described bearing seat 1, and the spacing back-up ring 4 in described rear end is jump ring, and jump ring is assemblied in jump-ring slot 12.Realized bearing axial limiting by jump ring, structure is simple, and jump ring has easy to assembly, and has dismountable feature, conveniently replaced.
As shown in Figure 3, the spacing back-up ring 4 in described rear end is formed in the riveting back-up ring in the axial rearward end mouth of bearing seat 1 for pressing, and the ear end face of the spacing back-up ring 4 in rear end flushes with the support bottom surface 21 of mounting body 2; Easy to assembly, product reliability is good, and the spacing back-up ring in rear end can be supported on the casing of equipment, ensures the reliability used.
As shown in Figure 4, described rear end spacing back-up ring 4 assemble welding is in the axial rearward end mouth of bearing seat 1, and the ear end face of the spacing back-up ring 4 in rear end is lower than the support bottom surface 21 of mounting body 2 or flush with the support bottom surface 21 of mounting body 2.The ear end face being preferably the spacing back-up ring 4 in rear end flushes with the support bottom surface 21 of mounting body 2; Easy to assembly like this, and the spacing back-up ring in rear end can be supported on the casing of equipment, ensures the reliability used.
Install for convenience of bearing fixing device, described mounting hole 22 be tapped hole, and mounting body 2 deviate from support bottom surface 21 face on be extended with screw hole column 23 around mounting hole 22, the interior threaded hole 231 of screw hole column 23 and mounting hole 22 shape, size are all identical.So direct screw-in bolt can realize bearing and be assemblied in fixed installation, without the need to other attaching nut, has easy for installation, and the advantage of compact structure, screw hole column makes installation more solid and reliable.
Bearing fixing device of the present utility model can form entirety with rolling bearing, can safeguard by integral replacing, safeguard more convenient, and it is stamping part, easy to process, with low cost, can not increase the maintenance cost of equipment.
