One inner ring assembly, described inner ring assembly comprises an inner ring main body, and this inner ring main body is circular, has a ring raceway A extended along inner ring body outer wall circumferencial direction at the middle part of the outer wall of inner ring main body;
One outer ring assembl, described outer ring assembl comprises an outer ring main body being sleeved on inner ring main body lateral wall and the tooth-shape structure be arranged on outside the main body of outer ring, outer ring main body shape ringwise, the outer wall of outer ring is evenly provided with some tooth-shape structures matched with chain that is that extend along outer ring body outer wall circumferencial direction, and tooth-shape structure and outer ring main body one-body molded, there is at the middle part of the inwall of outer ring main body a ring raceway B extended along outer ring inwall circumferencial direction, and raceway B and raceway A forms the overall raceway for ball component activity jointly;
One ball assembly, described ball assembly is made up of jointly several ball between inner ring main body and outer ring main body, and the bearing of trend of raceway that ball can be formed along raceway B and raceway A rolls;
One poted assemblies, described poted assemblies is made up of jointly two seal rings, and two seal rings are embedded between inner ring main body and outer ring main body respectively, and be positioned at the outer end of ball assembly, and the lateral wall of seal ring and madial wall are close to the inwall of outer ring main body, the outer wall of inner ring main body respectively.
Further, the hardness at the raceway A place on the main body madial wall of described outer ring is between HRC58-62, and all the other positions of outer ring main body and the hardness of tooth-shape structure are between HRC40-45.
The utility model has the advantage of: in the utility model, utilize design integrated between tooth-shape structure and outer ring main body, make this bearing can directly replace composite sprocket and chain carry out with the use of, eliminate the step of original sprocket wheel assembling, very convenient, and, when carrying, carried by ball assembly, can axial force be met, also can meet its diametral load; The outer ring of Novel chain bearing adopts raceway local quenching process, make the hardness at raceway place reach HRC58-62, guarantee raceway durable wear, and the hardness of remainder is HRC40-45, ensure that intensity and toughness, thus meet the performance requirement of overall low speed high-mechanic.
In addition, utilize two seals circle to seal, avoid dust and enter in bearing, affect it and use normally; Chain bearing in buying the utility model just can directly use, and purchases different parts, decrease purchase cost without the need to many places, and can directly use after purchasing, and installs after being assembled into composite sprocket again, very convenient.
