One side of the bearing outer ring of the device is self-sealed by adopting the sealing plate integrally arranged, more coal ash and other foreign matters can be effectively prevented from entering, the sealing effect is greatly improved, the other end of the bearing outer ring is sealed by adopting the sealing ring, so that the foreign matters can be effectively prevented from entering the interior of the bearing and the leakage of the grease is also prevented, and the sealing performance of the integrally sealed four-point contact bearing is greatly improved.
Description
Technical field
The utility model relates to technical field of bearings, is specifically related to a kind of four spot contact bearings of integrated sealing.
Background technique
The bearing that uses in coal mine machinery, 4 traditional tactile ball bearings of general employing, as shown in Figure 2, this bearing generally comprises bearing outer ring, bearing inner race and is arranged between the two steel ball, the madial wall of bearing outer ring and the outer side wall of bearing inner race form a raceway, and raceway is built-in with retainer, and steel ball is arranged on retainer, the both sides of steel ball adopt seal ring to seal, to prevent entering of the foreign matter such as coal ash on the colliery.When but the bearing of this structure is installed all adopt seal ring sealing with sealing inwardly outwardly, a side inwardly is because the sealing of seal ring does not have entering of coal ash, but a bearing side outwardly is direct and coal ash on the colliery contacts, and the internal surface of bearing outer ring is smooth periphery, and in actual conditions, the foreign matters such as coal ash are more, can not much seal bearing outer ring well.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides four spot contact bearings that a kind of selfsealings are effective, can effectively stop the integrated sealing that foreign enters.
To achieve these goals, the utility model has adopted following technological scheme:
a kind of four spot contact bearings of integrated sealing, comprise bearing outer ring and bearing inner race and be arranged on bearing outer ring and bearing inner race between steel ball, described bearing outer ring comprises outer ring body in the form of a ring, the outer side wall of described outer ring body is the cylndrical surface, described steel ball is arranged between outer ring body and bearing inner race, one annular side of the inwall of described outer ring body is provided with sealing plate, described sealing plate is with the collar extension sealing of this annular side of outer ring body, sealing plate is wholely set with the outer ring body, described bearing outer ring deviate from sealing plate a side be provided with seal ring, described seal ring is sealed and matched with bearing outer ring and bearing inner race respectively.
As preferably, the madial wall of described bearing outer ring and steel ball corresponding position are provided with outer raceway groove, and the outer side wall of described bearing inner race is provided with interior raceway groove, and described outer raceway groove and interior raceway groove are the rounded channels suitable with the steel ball shape.After adopting above-mentioned preferred version, utilize outer raceway groove on bearing outer ring and the interior raceway groove on bearing inner race that steel ball is positioned, can omit retainer, directly utilize these structures that steel ball is positioned, this structure can be installed the steel ball of greater number simultaneously, improve the bearing capacity of bearing, the loading ability of bearing better effects if.
As preferably, described seal ring is backbone sealing ring.After adopting above-mentioned preferred version, the structure of seal ring is stronger, can improve the bearing capacity of the utility model bearing.
As preferably, the madial wall of described bearing outer ring and seal ring corresponding position are provided with the external sealed groove of annular, the outer side wall of described bearing inner race and seal ring corresponding position are provided with the interior seal groove of annular, the interior ring side of described seal ring embeds in interior seal groove, the outer rim side of described seal ring embeds in the external sealed groove, forms seal ring described above and bearing outer ring and bearing inner race and is sealed and matched.After adopting above-mentioned preferred version, the sealing effect between seal ring and bearing outer ring and bearing inner race is better, can prevent effectively that foreign matter from entering the leakage of bearing inside and grease.
One side of the bearing outer ring of four spot contact bearings of integrated sealing of the present utility model adopts the sealing plate that is wholely set to carry out selfsealings, even the more foreign matters such as coal ash are arranged, also can effectively prevent entering of these coal ash foreign matters, sealing effect improves greatly, the other end adopts the seal ring sealing can prevent effectively that foreign matter from entering the leakage of bearing inside and grease, has greatly improved the sealability of four spot contact bearings of integrated sealing.
