Abstract
The utility model discloses a kind of stuffing box bearing with annular knurl design, comprise: outer ring, inner ring, rolling element, retainer and Sealing, retainer assembly is formed in the pocket hole that described rolling element is arranged on described retainer, described retainer assembly is arranged between described outer ring raceway and described inner ring raceway, described Sealing is arranged between described outer ring and described inner ring equally, and match with the seal groove of described outer ring, the surface of the seal groove of described outer ring is prolonged circumferencial direction and is pressed with annular knurl.By the way, the utility model can strengthen the frictional force between Sealing and outer ring seal groove, guarantees bearing geo-stationary between Sealing and outer ring seal groove in the running, does not wriggle, thus effectively ensure the sealability of bearing, improve the working life of bearing.
Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of stuffing box bearing with annular knurl design.
Background technique
For stuffing box bearing, its outer ring generally all has seal groove, for the installation of bearing seal.For ensureing the sealability of bearing, between bearing seal outer lip and outer ring seal groove, need fastening installation.When bearing working operates, there is a stiction f1 between bearing seal outer lip and outer ring seal groove, this frictional force f1 can ensure that between Sealing outer lip and outer ring seal groove, geo-stationary is motionless, does not wriggle, thus ensures the sealing effect of bearing.
But for contact seal bearing, during its work running, Relative friction between the epipharynx of bearing seal and the little cylindrical of inner ring, produces frictional force f2.As f2 >=f1, there will be the relative creep between Sealing outer lip and outer ring seal groove, the situation of even running-in, now, the sealability of bearing will lose efficacy to a great extent, the working life of the bearing that terminates in advance.
Therefore, for ensureing the stability of bearing seal performance, we are badly in need of a kind of novel seal groove structure, effectively can strengthen the frictional force f1 between seal groove and Sealing outer lip, guarantee that bearing is when working running, can not wriggle between Sealing and outer ring seal groove (f1 > f2), thus ensure the sealability of bearing, ensure the working life of bearing.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of stuffing box bearing with annular knurl design, the frictional force between bearing seal and outer ring seal groove can be strengthened, guarantee bearing geo-stationary between Sealing and outer ring seal groove in the running, do not wriggle, thus effectively ensure the sealability of bearing, improve the working life of bearing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of stuffing box bearing with annular knurl design, comprise: outer ring, inner ring, rolling element, retainer and Sealing, retainer assembly is formed in the pocket hole that described rolling element is arranged on described retainer, described retainer assembly is arranged between described outer ring raceway and described inner ring raceway, described Sealing is arranged between described outer ring and described inner ring equally, and match with the seal groove of described outer ring, the surface of the seal groove of described outer ring is prolonged circumferencial direction and is pressed with annular knurl.
In the utility model preferred embodiment, the compacting degree of depth of described annular knurl is 0.15-0.2mm.
In the utility model preferred embodiment, the compacting degree of depth of described annular knurl is 0.15mm.
In the utility model preferred embodiment, described rolling element is steel ball.
The beneficial effects of the utility model are: by the annular knurl of the seal groove surface compacting certain depth at bearing outer ring, effectively can increase the frictional force between Sealing and outer ring, ensure bearing in the running, do not wriggle between Sealing and outer ring, thus strengthen the sealability of bearing, improve the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of stuffing box bearing one preferred embodiment with annular knurl design of the utility model;
Fig. 2 is the partial enlarged drawing of A shown in Fig. 1;
Fig. 3 is that B shown in Fig. 2 is to schematic diagram;
In accompanying drawing, the mark of each parts is as follows: 1, outer ring, and 11, seal groove, 2, Sealing, 3, retainer, 4, rolling element, 5, inner ring, 6, annular knurl.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of stuffing box bearing with annular knurl design, comprise: outer ring 1, inner ring 5, rolling element 4, retainer 3 and Sealing 2, retainer assembly is formed in the pocket hole that described rolling element 4 is arranged on described retainer 3, between the raceway that described retainer assembly is arranged on described outer ring 1 and the raceway of described inner ring 5, described Sealing 2 is arranged between described outer ring 1 and described inner ring 2 equally, and match with the seal groove 11 of described outer ring 1, the surface of the seal groove 11 of described outer ring 1 is prolonged circumferencial direction and is pressed with annular knurl 6.
The compacting degree of depth of described annular knurl 6 is 0.15-0.2mm, be preferably 0.15mm, knurl wheel compacting is adopted to form, the frictional force between annular knurl 6 and Sealing 2 can be made to increase, ensure bearing in the running, do not wriggle between the seal groove 11 of Sealing 2 and outer ring 1, thus strengthen the sealability of bearing, improve the working life of bearing.
In the present embodiment, described rolling element 4 is steel ball.
The utility model discloses a kind of stuffing box bearing with annular knurl design, by the annular knurl of the seal groove surface compacting certain depth at bearing outer ring, effectively can increase the frictional force between Sealing and outer ring, ensure bearing in the running, do not wriggle between Sealing and outer ring, thus strengthen the sealability of bearing, improve the working life of bearing.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
