Detailed Description
The invention provides a thrust angular contact ball bearing for a steering gear, which comprises a shaft ring 1, a seat ring 2, a retainer 3 and rolling bodies, wherein the bearing is more suitable for installation and use by redesigning the structures of the shaft ring 1 and the seat ring 2.
In the present invention, the "upper" and "lower" are based on the reference when the race 2 of the bearing is laid down and the ring 1 is laid flat on top. The inner part is the inner part at one side of the center of the bearing, and the outer part is the opposite side.
In this embodiment, be provided with on the pore wall of the hole of collar 1 with the integrative internal thread 11 structure of collar 1 integration, make collar 1 be equivalent to a nut when the installation, with the installation threaded connection that corresponds can, made things convenient for the assembly greatly. A flange 12 extending toward the race 2 is provided at a bottom portion of the outer side of the ring 1 facing the race 2, the flange 12 wraps the outer end portion of the race 2, and an interval between the flange inner wall 121 and the outer wall of the outer end portion of the race 2 is 0.2 to 0.5mm, i.e., d0 shown in fig. 4, thereby forming an upper seal structure in which the flange 12 and the upper side of the outer end portion of the race 2 are staggered. In the upper sealing structure, the flange 12 on the outer end of the shaft ring 1 is matched with the outer end 22 of the seat ring 2, and the gap is limited within a small range, so that the upper sealing structure has stable and effective sealing function, and a sealing cover between the outer side of the shaft ring 1 and the outer side of the seat ring 2 is eliminated, so that the upper sealing structure is convenient to assemble and use in practice.
Further, the bore diameter of the inner bore of the retainer 2 is larger than the bore diameter of the shaft ring 1, and in a preferred embodiment, the difference in bore diameter between the inner bore of the retainer 2 and the inner bore of the shaft ring 1 is on the order of 0.05mm or less, preferably 0.01mm or less, so that when the shaft ring 1 is mounted to a mounting shaft of a steering gear, the clearance d1 between the retainer 2 and the mounting shaft is extremely small, and a lower seal structure is naturally formed between the retainer 2 and the mounting shaft.
It should be noted that the channels on the shaft ring 1 and the seat ring 2 are arranged obliquely and present the structural characteristics of high outside and low inside, so that the upper sealing structure formed by the oblique channels and the clearance fit action of the flange 12 of the shaft ring 1 and the seat ring 2 can effectively prevent the entry of foreign matters or the outflow of lubricating grease; when the bearing rotates and the lubricating oil is thrown by the centrifugal force, the amount of the lubricating oil flowing out is greatly reduced due to the blockage of the inclined channel.
With the structure, in the embodiment, the flange 12 on the outer side end of the shaft ring 1 is matched with the outer side end 22 of the seat ring 2 to form an upper sealing structure, and the inner side end 21 of the seat ring 2 is matched with the mounting shaft by a small clearance to form a lower sealing structure, so that the bearing is protected from the outside, the use of a sealing cover in the traditional structure is eliminated, the sealing without the sealing cover between the inner side end 21 of the shaft ring 1 and the inner side end 21 of the seat ring 2 is realized, the bearing structure is simplified, and the assembly and the use of the bearing are cheaper.
Embodiment 2 this embodiment provides a thrust angular contact ball bearing for a steering gear, which is further provided on the basis of embodiment 1 as follows: the inner hole wall of the seat ring 2 extends radially to the position of the inner hole wall of the shaft ring 1 to form an extension channel 5, the length of the extension channel 5 is not less than 0.5mm, and the length d1 of the extension channel 5, which is opposite to the upper side wall 23, is not less than 0.3 mm.
In this embodiment, the retainer 3 has a first radial plane 31 and a second radial plane 32 which are in parallel clearance fit with the lower sidewall 212 and the upper sidewall 13 of the extension passage 5, respectively. In a preferred embodiment, the clearance d4 between the inner end 21 of the retainer 3 and the lower sidewall 212 of the extension passage 5 is 0.05-0.2 mm. Moreover, the inner end 21 of the retainer 3 is opposite to the upper side wall 211 of the extension passage 5, and the gap d3 between the inner end 21 of the retainer 3 and the upper side wall 211 of the extension passage 5 does not exceed 1/2 of the gap d4 between the inner end 21 of the retainer 3 and the lower side wall 212 of the extension passage 5.
Through the clearance fit of the retainer 3 and the sealing channel, the sealing effect of the extension channel 5 is improved.
In the above embodiment, in order to ensure the sealing effect of the lower seal structure, the inner hole surface of the cage 4 may be provided as the axial plane 33 parallel to the axial direction of the shaft ring 2 and the race 1. When the bearing rotates, the inner hole surface of the retainer 4 is the axial plane 33, so that the inner hole surface and the mounting shaft can form a state of being relatively parallel and not interfering with each other in the rotating process, and the innermost end of the retainer 4 is still positioned in the extension channel and still has a certain distance with the mounting shaft, so that the phenomenon that the mounting shaft generates suction force to attract lubricating grease in the inner cavity where the retainer 4 and the steel ball 3 are positioned in the rotating process can be effectively prevented, the steel ball 3 is fully lubricated, and the bearing can normally run.
In conclusion, the invention provides the angular contact thrust ball bearing convenient to mount, which can be mounted in place only by mounting the locking nut once, thereby not only reducing the parts for mounting the assembly, but also achieving the effects of locking the bearing and normally operating the bearing. In addition, because the flange 12 structure with sealing function is arranged in the shaft ring 1, the inner diameter design of the seat ring 2 is designed according to the clearance between the shaft and the flange, the sealing function can be realized, and the sealing structure is not required to be installed in the steering assembly.
