Abstract
The invention relates to a sealing structure for a bearing. The sealing structure is characterized in that an annular sealing ring is arranged on the joint of an outer bearing ring and an inner bearing ring, and the outer surface of an annular sealing ring body is provided with multiple teeth and a wing panel which extends outwards; the inner bearing ring is provided with a sealing groove, the annular sealing ring body is embedded into the sealing groove of the inner bearing ring, the wing panel is connected to the end face of the outer bearing ring in an overlapped mode, and the sealing structure for the bearing is formed. According to the sealing structure, the sealing degrees of the inner bearing ring and the outer bearing ring are improved, a rolling channel of the bearing is prevented from being accessed by foreign objects, and a sealing mechanism is prevented from being damaged due to the fact that a sealing block in the sealing mechanism is prone to falling and winding other structures.
Description
Technical field
The present invention relates to a kind of sealing configuration of bearing.
Background technique
Bearing is the supporting member in mechanical transmission mechanism, and for determining running shaft and other part relative movement position, its quality directly affects the service behaviour of mechanical complete machine, is driven the motion of associated mechanisms by the running of bearing.Bearing operates in various environment, particularly rugged environment (as: dust storm, water, oil, salt fog etc.), and foreign matter enters raceway easily via the gap between the inside and outside circle of bearing, makes bearing on-stream destroyed.In order to solve the problem, need to arrange sealing mechanism to prevent Bearing inner destructurized, under the state avoiding bearing to enter raceway at oil starvation and foreign matter, running uses, but sealing mechanism of the prior art all exists the problems such as poorly sealed, easy leakage of oil.In addition, the sealing block in sealing mechanism easily comes off and sealing block is easily wound around other structures, causes sealing mechanism to damage.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of sealing configuration of bearing.
The sealing configuration of described a kind of bearing, arranges an O-ring seal; Described O-ring seal is arranged on the binding site of bearing outer ring and bearing inner race; The outer surface of O-ring seal body has some teeth, and described O-ring seal body has outwardly directed fin; Described bearing inner race has seal groove; Described O-ring seal body embeds in the described seal groove of bearing inner race, and described fin is overlapped on the end face of bearing outer ring, forms the sealing configuration of described bearing.
Described teeth on described O-ring seal body, fin and described O-ring seal body are formed in one structure.
Invention increases the seal degree of bearing inner race, bearing outer ring, avoid bearing to be entered the state of raceway by foreign matter, the sealing block avoided in sealing mechanism easily comes off and sealing block is easily wound around other structures, causes sealing mechanism to damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of O-ring seal in the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A sealing configuration for bearing, arranges an O-ring seal 2, and described O-ring seal 2 is arranged on the binding site of bearing outer ring 1 and bearing inner race 3; With reference to Fig. 2, the outer surface of O-ring seal body 6 has some teeth 4; Described O-ring seal body 6 has outwardly directed fin 5, described bearing inner race 3 has seal groove; Described O-ring seal body 6 embeds in the described seal groove of bearing inner race 3, and described fin 5 is overlapped on the end face of bearing outer ring 1, forms the sealing configuration of described bearing.Described teeth 4 on O-ring seal body, fin 5 and described O-ring seal body 6 are formed in one structure.
Invention increases the seal degree of bearing inner race, bearing outer ring, avoid bearing to be entered the state of raceway by foreign matter, the sealing block avoided in sealing mechanism easily comes off and sealing block is easily wound around other structures, causes sealing mechanism to damage.
Claims (2)
