Description
Technical field
The utility model relates to a kind of axis part, specifically a kind of retaining rings.
Background technique
Circlip for hole is installed in circular hole, as the axial movement for preventing components, belongs to standard component, state's label:
GB893.1-1986, specification 8-200mm, material 65Mn, heat treatment hardness HRC44-51.The outer diameter of this kind of retaining ring is than assembly circular hole
Diameter is slightly larger, therefore need to be installed using Circlip tongs, will first clamp retaining ring when installation in the pincers hole of plier insertion retaining ring, then by retaining ring
It is put into pre-processed circular hole inside groove.
But such mounting means will cause reliability for bearing axial load and being greater than for the retaining ring of 200mm
It reduces, so the circular hole greater than 200mm selects end cover part to be fixed mostly.In addition, the hole elasticity gear greater than 200mm
, since the planform by itself is limited, easily there is moderate finite deformation, and finished product manufacture difficulty during heat treatment in circle
It increases.And the retaining ring greater than 200mm sold on the market now, using effect and price are less desirable, and are not formed
Unified standard.
Utility model content
The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, provide a kind of hole retaining ring, which answers
Have the characteristics that structure is simple, easy for installation, high reliablity.
The technical solution of the utility model is:
A kind of hole retaining ring, it is characterised in that: the hole includes the interior clamping ring and outer gear fixed by fastener with retaining ring
Circle；The outer retaining ring is made of several arc block plates for being arranged in annulus, and the top surface of baffle is equipped with and interior clamping ring outer circumference surface
The arc groove to match, adjacent baffle keep a fixed spacing in a circumferential direction；The interior clamping ring is fixed on the recessed of baffle
On slot.
The outer diameter of the interior clamping ring is greater than the internal diameter of outer retaining ring and is less than the outer diameter of outer retaining ring.
The fastener is screw.
The connecting hole for securing member is equipped on the interior clamping ring and baffle.
The beneficial effects of the utility model are:
The utility model processing it is relatively easy, there is no excessive demand to material, specification and size also without limitation, and
Identical fixed form (being mounted in circular hole inside groove) is used with the circlip for hole of standard, there is stronger reliability；Separately
Outside, the utility model will not generate boss, good appearance, it is ensured that the planarization of host housing on host surface.

Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Figure 1, a kind of hole retaining ring, including interior clamping ring 1, outer retaining ring and fastener 3.
The outer diameter of the interior clamping ring is greater than the internal diameter of outer retaining ring and is less than the outer diameter of outer retaining ring, and interior clamping ring, which is equipped with, to be used
In the upper connecting hole 1.1 of securing member.
The outer retaining ring includes several arc block plates 2, and it is (outer with interior clamping ring that the top surface of baffle is equipped with arc groove 2.1
Periphery matches), baffle is equipped with the lower connecting hole 2.2 for securing member, and lower connecting hole is located in arc groove.Institute
Baffle is stated to be arranged in the surrounding of interior clamping ring and fix with interior clamping ring that (interior clamping ring is fixed on the recessed of baffle by fastener
On slot), these baffles are arranged in circular ring shape, and adjacent baffle keeps a fixed spacing (to guarantee that baffle can smoothly pacify in a circumferential direction
Dress).Screw or bolt can be used in the fastener.
The application method of the utility model are as follows:
As shown in figure 9, baffle first to be filled in the outer retaining ring of composition in the inside groove 9.2 of pre-processed circular hole 9.1 respectively, so
Interior clamping ring is put into circular hole again afterwards, it is (existing that interior clamping ring and outer retaining ring are finally connected to form a whole 7 using fastener
Some retaining rings are as shown in mark 8 in Fig. 9).
In Fig. 9, the thickness of circular hole inside groove is slightly larger than the thickness of baffle, to ensure that baffle can be filled in inside groove.Circular hole inside groove
Thickness it is selected according to specification, for example, when the utility model uses the ruler matched with standard circlip for hole φ 100
When very little, baffle with a thickness of 2.5mm, the thickness of circular hole inside groove is then 2.7 (+0.14/0) mm.
