Abstract
The utility model discloses a kind of bearing back-up ring and bearing assembly, it is related to technical field of bearings.The back-up ring includes flexible c-type back-up ring main body, the c-type back-up ring main body is adapted with the circlip groove on bearing block, elastic opening, the lug boss for being provided with several indents being spaced in the c-type back-up ring main body are formed between two free ends of the c-type back-up ring main body.The generally elastic component of the back-up ring, which is provided with elastic opening, and bearing is positioned by the lug boss on the back-up ring.When installing the back-up ring, the elastic opening can be reduced, and now, the diameter of the back-up ring diminishes, and easily the back-up ring can be installed in the circlip groove；When needing to dismantle the back-up ring, the lug boss facilitates instrument or finger to insert, and therefore, the back-up ring has the advantages of installation and removal facilitate.
Description
Technical field
It the utility model is related to technical field of bearings, more particularly to a kind of bearing back-up ring and bearing assembly.
Background technology
Bearing is generally stiff with back-up ring with one of common components that back-up ring is plant equipment, bearing common at present
C-type laminated structure, as shown in Figure 1.However, non-resilient back-up ring dismounting is inconvenient, and may be to bearing during dismounting
Or bearing block causes to damage.
Utility model content
Technical problem to be solved in the utility model is how to provide a kind of bearing back-up ring of convenient disassembly.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of bearing back-up ring, its feature
It is：Including flexible c-type back-up ring main body, the c-type back-up ring main body is adapted with the circlip groove on bearing block, the C
Elastic opening is formed between two free ends of type back-up ring main body, what is be spaced in the c-type back-up ring main body is provided with several
Recessed lug boss.
Further technical scheme is：The lug boss is provided with five, is symmetrically arranged at the elastic opening two
In the c-type back-up ring main body of side.
The utility model additionally provides a kind of bearing assembly.A kind of bearing assembly, it is characterised in that：Including described bearing
With back-up ring, bearing and bearing block, the bearing is located in the mounting hole of the bearing block, the inwall of the mounting hole on the upside of bearing
Circlip groove is provided with, the back-up ring is located in the circlip groove, and the inside edge of the lug boss is located at bearing inner race and outer ring
Between, and the lug boss directly with the bearing touch.
It is using beneficial effect caused by above-mentioned technical proposal：The generally elastic component of the back-up ring, which is provided with
Elastic opening, bearing is positioned by the lug boss on the back-up ring.When installing the back-up ring, the elastic opening can
To reduce, now, the diameter of the back-up ring diminishes, and easily the back-up ring can be installed in the circlip groove；When needs are torn open
When unloading the back-up ring, the lug boss facilitates instrument or finger to insert, and therefore, the back-up ring has installation and removal convenient excellent
Point.

With doing similar popularization in the case of new intension, therefore the utility model is not limited by following public specific embodiment.
As shown in Fig. 2 the utility model embodiment discloses a kind of bearing back-up ring, including flexible c-type back-up ring
Main body 1.The c-type back-up ring main body 1 is adapted with the circlip groove 21 on bearing block 2, two freedom of the c-type back-up ring main body 1
Elastic opening 11, the lug boss 12 for being provided with several indents being spaced in the c-type back-up ring main body 1 are formed between end.
Preferably, as shown in Fig. 2 the lug boss 12 is provided with five, the elastic opening both sides are symmetrically arranged at
The c-type back-up ring main body on.It should be noted that the specific number and particular location of the lug boss can also be other
Mode.
As shown in Figure 3-4, the utility model embodiment also discloses a kind of bearing assembly, including described bearing gear
Circle, bearing 3 and bearing block 2.The bearing 3 is located in the mounting hole of the bearing block 2, the mounting hole of the upside of bearing 3 it is interior
Wall is provided with circlip groove 21, and the back-up ring is located in the circlip groove 21, and the inside edge of the lug boss 12 is located in bearing
Between circle and outer ring, and the lug boss 12 directly contacts with the bearing 3.
The generally elastic component of the back-up ring, which is provided with elastic opening, by the lug boss on the back-up ring to bearing
Positioned.When installing the back-up ring, the elastic opening can reduce, and now, the diameter of the back-up ring diminishes, and can facilitate
