Abstract
The utility model discloses a combined bearing which comprises a first bearing and a second bearing, wherein the first bearing comprises a first outer ring, a first inner ring and a first rolling body positioned between the first inner ring and the first outer ring; the second bearing comprises a second outer ring, a second inner ring and a second rolling body positioned between the second inner ring and the second outer ring; a first connection ring is arranged on the right side of the first outer ring, and multiple connection teeth are arranged on the first connection ring; a second connection ring is arranged on the left side of the second outer ring, and connection tooth slots matched with the connection teeth are formed in the second connection ring; the first bearing is jointed with the left side of the second bearing, and the connection teeth are inserted into the connection tooth slots. When two combined bearings disclosed by the utility model are in use, the outer rings are connected together to realize synchronous rotation, and the condition of abrasion of lateral contact surfaces of the outer rings of the bearings occurring when the rotation speeds are different or one bearing rotates while the other one does not rotate is avoided.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of bearing being used in combination.
Background technique
Existing bearing is all generally single row bearing, when bearing load is larger, can use multiple row roller bearing, also can use many cover bearings to be used in combination, when many covers bearing is used in combination, often the outer ring of its bearing or inner ring sometimes one turn one do not turn form friction, cause bearing outer ring or inner ring side direction surface of contact form wearing and tearing, have influence on bearing life.
Summary of the invention
The easily deficiency of wearing and tearing of side direction surface of contact while being used in combination in order to overcome existing bearing, the utility model provides a kind of combination bearing of overcoat interlock.
The technical scheme in the invention for solving the technical problem is: combination bearing, comprise clutch shaft bearing and the second bearing, described clutch shaft bearing comprises the first outer ring, the first inner ring, the first rolling element between the first inner ring and the first outer ring, between described the first inner ring and the first outer ring, is also provided with the first seal; The second described bearing comprises the second outer ring, the second inner ring, the second rolling element between the second inner ring and the second outer ring, between described the second inner ring and the second outer ring, is also provided with the second seal; The first described right side, outer ring is provided with the first fastener rings, and described the first fastener rings is provided with some connection teeths; Described the second left side, outer ring is provided with the second fastener rings, and the second described fastener rings is provided with the teeth groove that is connected with connection teeth coupling; Described clutch shaft bearing is bonded on the second bearing left side and described connection teeth inserts in described connection teeth groove.
The utility model also comprises another kind of combination bearing, comprise clutch shaft bearing and the second bearing, described clutch shaft bearing comprises the first outer ring, the first inner ring, the first rolling element between the first inner ring and the first outer ring, between described the first inner ring and the first outer ring, is also provided with the first seal; The second described bearing comprises the second outer ring, the second inner ring, the second rolling element between the second inner ring and the second outer ring, between described the second inner ring and the second outer ring, is also provided with the second seal; The first described right side, outer ring is provided with the first fastener rings, and described the first fastener rings is provided with some connection squares; Described the second left side, outer ring is provided with the second fastener rings, and the second described fastener rings is provided with and the connection oblong slot that is connected block matching; Described clutch shaft bearing is bonded on the second bearing left side and described connection square inserts in described connection oblong slot.Adopt and connect square replacement connection teeth, shear strength is higher.More be not easy to skid.
The utility model puts band installation shaft and from left to right puts successively clutch shaft bearing and the second bearing in use, and the outer ring of the outer ring of clutch shaft bearing and the second bearing is taken jail and linked together.
The beneficial effects of the utility model are: when two combination bearings are used, outer ring links together, thereby rotate while rotating simultaneously, can not cause rotating speed inconsistent or one rotate another not situation of rotation situation lower bearing outer ring side direction contact surface abrasion.
