Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of limit oiliness bearing, including bearing main body 1, the axis
It holds 1 inner wall of main body and oiliness shaft lining for powder metallurgy 2 is installed, and movable position-limit mechanism 3 is installed, and bearing inside bearing main body 1
1 one end of main body is equipped with from lock set 4, when installing and using bearing, by movable position-limit mechanism 3 to bearing main body 1 into
The adjustable activity limit of row, under conditions of not needing extraneous be fixedly mounted, the stabilization that bearing main body 1 still may be implemented makes
With realizing the quick limit of bearing, can use in different environments, and being easy to implement fastly from lock set 4 using end
Speed installation, it is simple and convenient.
The activity position-limit mechanism 3 includes the loose slot 301 being arranged in inside bearing main body 1, and the loose slot 301 is inner
Portion one end is connected separately with several expansion slot 303 by several cone tanks 302, is equipped with inside the loose slot 301 crowded
Pressure ring 304, the extrusion ring 304 are connected with several by external one end and adjust stud 305, and 304 other end of extrusion ring is connected with
Several wedge-shaped catch 306,306 outer surface of wedge-shaped catch are provided with bronze finish 307, pacify inside the expansion slot 303
Equipped with live metal bar 308, one end is connected with tilted vane 310 by spring stack 309 to the live metal bar 308 close to the inner portion,
308 other end of live metal bar is connected with locking head 311.
When in use, it when bearing main body 1 is inserted into corresponding slot inside installation, needs to fix bearing main body 1,
Multiple adjusting studs 305 are rotated simultaneously at this time, so that multiple adjusting studs 305 are simultaneously to the extrusion ring 304 inside loose slot 301
Squeezing action is generated, extrusion ring 304 is mobile towards the direction of cone tank 302 under squeezing action, so that extrusion ring 304
Push wedge-shaped catch 306 constantly mobile, as wedge-shaped catch 306 is constantly manoeuvred into inside cone tank 302, in wedge-shaped catch
Under 306 impetus, tilted vane 310 slides on the smooth bronze finish 307 of wedge-shaped catch 306, since wedge shape is kept off
Block 306 is continuously increased in continuous moving process with the contact surface of tilted vane 310 height, so that live metal bar 308
The spring stack 309 of one end is compressed close to the inner portion, pushes live metal bar 308 mobile to outside later, live metal bar 308 is pierced by
Expansion slot 303 simultaneously extends outward, and bearing main body 1 is fastened on mounting groove by the locking head 311 of 308 outer end of live metal bar
Inner wall, to realize that stablizing for bearing main body 1 is installed.
For different size of mounting groove, the extruded length of stud 305 is adjusted by changing, changes wedge-shaped catch at once
306 compressive plane adjusts the extrusion length of live metal bar 308, locking head 311 can be fixed on different size of mounting groove
Inner wall, use when, are more convenient, improve the use scope of entire bearing, can meet different use demands.
311 surface of locking head is provided with several friction plates 9, and 9 surface of friction plate is uniformly equipped with several
Frosted protrusion 5, when in use, the friction plate 9 by surface with frosted protrusion 5 increases locking head 311 to locking head 311
Rubbing action improves stability, prevents from loosening when fixed.
It should be added that 302 inner wall of cone tank is equipped with several cushion compounds 6,1 table of bearing main body
Face be equipped with several with adjust the clamping spiral-tube 7 that connect of 305 spiral of stud, and 7 surface of clamping spiral-tube be equipped with it is several
A heat conduction copper sheet 8 guarantees that wedge-shaped catch 306 can stablize movement, and utilize clamping spiral shell by the position-limiting action of cushion compound 6
Rotation cylinder 7 provides accommodation space and guiding protective effect to adjust the use of stud 305, and when bearing uses, passes through
The heat conduction copper sheet 8 on 7 surface of clamping spiral-tube plays good heat spreading function.
It further illustrates, it is described to be mounted on the becket 401 of 1 one end of bearing main body including several from lock set 4,
Several threaded holes 402 are installed, and 401 outer end face of becket is equipped with isolation pad 403 on the becket 401,
, as needed can be by the way that one end of bearing main body 1 be fixedly mounted from lock set 4 when use, use is more convenient, leads to
The multiple threaded holes 402 for crossing becket 401 are installed, more convenient to use, at the same isolation pad 403 can play it is good
Insulation blocking effect, prevents becket 401 from damaging because of squeezing action.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
