Abstract
The utility model relates to a retainer ring for a combined hole. A cross universal transmission shaft is equipment in which multiple retainer rings are used, eight retainer rings for holes are generally used on a shaft, and a phenomenon that a cross bearing drops due to breakage of the retainer ring, so that the transmission shaft is ineffective occurs in the actual application process. The retainer ring comprises a pressing plate (1) and a retainer ring block combination, wherein the retainer ring block combination is formed by fastening every two of the group of retainer ring blocks (2); and a boss (1-2) is formed below the pressing plate. The product is used for positioning a bearing end, one of two sides of the retainer ring is provided with the boss and the other side of the retainer ring is provided with a pin shaft in the operating process, the whole retainer ring is uniformly stressed, and the retainer ring is effectively prevented from being broken.
Description
Technical field:
the utility model relates to a kind of location and fixed combination formula hole that is used for hole axle head part and uses back-up ring.
Background technique:
part should be located with reliably fixing on axle vertically exactly, also can bear axial force and not produce axial displacement so that it has definite mounting point.Axial fixing method commonly used has the shaft shoulder, axle collar location, nut location, sleeve location and shaft end ring location etc.The axially locating of parts on shaft and fixation method depend primarily on the size of axial force.When the suffered axial force of part is big, modes such as the shaft shoulder commonly used, the axle collar, interference fit; When receiving medium axial force, modes such as available sleeve, round nut, shaft end ring, conical surface and circular cone pin.Shaft end ring, the outer jump ring that is commonly called as exactly, he makes with spring steel, struts with Circlip tongs during use, is placed on the jump ring groove on the axle, unclamp Circlip tongs after, be stuck in the groove on the axis hole through elastic reset, play and do not allow bearing, part axials such as gear move.Must use Circlip tongs during installation, jaw is inserted in the pincers hole of back-up ring and shrink back-up ring, just can put into pre-processed axis hole groove.The hole is wider with back-up ring using scope in commercial production, and it is simple in structure, installation is convenient, but back-up ring fracture is general phenomenon.
cross universal transmission shaft is to use the more a kind of equipment of back-up ring, generally has eight holes to use back-up ring on the axle, can occur back-up ring fracture in actual use and causes the cross bearing packet to come off to cause the transmission shaft failure phenomenon.
patent relevant with this case has the CN200420031115.9 circlip for hole; It is with standard circlip for hole matrix; On the matrix inner peripheral surface, be provided with and be connected as a single entity with it and, but the phenomenon of jump ring fracture in use also can occur to the interior radial teeth of central protuberance.
patent CN200820230226.0 discloses a kind of hole and circlip for shaft; Adopt circlip for hole and circlip for shaft to be used; The axial force that produces in the working procedure is directly carried by circlip for hole and circlip for shaft; Be convenient to bear larger axis to load through the thickness that increases its axial direction merely, it is very limited that it bears axial force, do not overcome the working procedure guide ring defective of fracture easily.
The model utility content:
The purpose of
the utility model is that the problem to above-mentioned existence provides a kind of combined type hole use back-up ring, can effectively prevent the Sealing shield ring breaking releasing and causes the phenomenon generation of equipment failure.
Above-mentioned purpose realizes through following technological scheme:
Back-up ring is used in
combined type hole, comprises the combination of pressing plate and one group of back-up ring piece, and described back-up ring piece combination is formed by connecting interlocking in twos between one group of back-up ring piece, has boss below the described pressing plate.
Back-up ring is used in
described combined type hole, and described back-up ring number of blocks is no less than 3.
Back-up ring is used in
described combined type hole, and the boss external diameter of described pressing plate is less than the internal diameter of back-up ring piece combination.
Back-up ring is used in
described combined type hole, has the dismounting aperture on each described back-up ring piece.
Back-up ring is used in
described combined type hole, has one group of chek bolt on the described pressing plate.
Beneficial effect:
1. the utility model back-up ring in the course of the work both sides one side of back-up ring have boss, opposite side is a bearing pin, whole back-up ring is stressed evenly, has effectively avoided the back-up ring fracture; Adopt the compound mode that interlocks in twos between the back-up ring piece, easy installation and removal, and avoided the phenomenon of each back-up ring piece landing.
the utility model is provided with the back-up ring piece more than at least 3, makes the length of each back-up ring piece less than the internal diameter of equipment axis hole, guarantees to be installed in the draw-in groove smoothly.
The boss external diameter of
the utility model pressing plate is less than the internal diameter of back-up ring piece combination; Its boss is just in time fixed the back-up ring inner ring behind the pressing plate installation in position; Pressing plate is fixed on the apparatus body through chek bolt; The axial float power of bearing pin acts directly on the back-up ring and does not contact with pressing plate, and the bearing pin axially locating is effective.
All be provided with the dismounting aperture on each back-up ring piece of
the utility model, be convenient to installing/dismounting.
