Description
Technical field
The utility model relates to a kind of bearing, specifically, relates to a kind of wind-driven generator double-sealing main bearing.
Background technique
Main bearing is the critical component in the wind power generating set, the quality of its performance directly influences the reliability of fan operation, and to guarantee main bearing energy proper functioning, then must make it obtain good lubricating, therefore, except will be regularly adding the new grease lubrication, also require main bearing to obtain good sealing to main bearing.Because existing seal ring all is to be exposed to airbornely, oxidative phenomena is very serious, damages easily, and sealability is difficult to effectively be guaranteed, like this, tends to reduce the functional reliability of main bearing, influences the working life of main bearing.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of functional reliability height, the wind-driven generator double-sealing main bearing of long service life.
The utility model is achieved through the following technical solutions: it comprises the main bearing inner ring, main bearing outer ring I, main bearing outer ring II, also comprise the seal ring I, the seal ring II, the seal ring III, the seal ring IV, main bearing inner ring upper end is provided with the groove I, main bearing outer ring I is provided with stepped slot I and stepped slot II, the seal ring II is located on the stepped slot I, the stepped slot II is provided with the pressing plate I that the seal ring II is played pressuring action, the pressing plate I is fixed on the I of main bearing outer ring, seal ring I one end is fixed in the groove I, the seal ring I the other end is close on the pressing plate I, main bearing inner ring lower end is provided with the groove II, stepped slot III and stepped slot IV are arranged on the II of main bearing outer ring, the seal ring IV is located on the stepped slot III, the stepped slot IV is provided with the pressing plate II that the seal ring IV is played pressuring action, the pressing plate II is fixed on the II of main bearing outer ring, and seal ring III one end is fixed in the groove II, and the seal ring III the other end is close on the pressing plate II end face.
The utility model with nexine seal ring and isolated from atmosphere, can effectively prevent that the nexine seal ring is oxidized by outer seal ring, makes main bearing can obtain excellent sealing, helps prolonging the working life of main bearing.
Description of drawings
Fig. 1 is the utility model example structure schematic representation;
Fig. 2 is main bearing inner ring embodiment illustrated in fig. 1 and main bearing outer ring I, main bearing outer ring assembly structure schematic representation;
Fig. 3 is an A embodiment illustrated in fig. 1 place structure for amplifying schematic representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
With reference to accompanying drawing, present embodiment comprises main bearing inner ring 1, main bearing outer ring I 6, main bearing outer ring II 7, seal ring I 2, seal ring II 4, seal ring III 11, seal ring IV 10, main bearing inner ring 1 upper end is provided with groove I 12, main bearing outer ring I 6 is provided with stepped slot I 13 and stepped slot II 14, seal ring II 4 is located on the stepped slot I 13, stepped slot II 14 is provided with the pressing plate I 3 to 4 pressuring actions of seal ring II, pressing plate I 3 is fastened on the main bearing outer ring I 1 by bolt I 5, seal ring I 2 one ends are fixed in the groove I 12, seal ring I 2 the other ends are close on the pressing plate I 3, because the interaction between seal ring I 2 and pressing plate I 3 end faces, thereby make that seal ring II 4 and outside air are isolated, seal ring II 4 is closed in the lubricating grease system, is difficult for oxidized; Main bearing inner ring 1 lower end is provided with groove II 15, stepped slot III 16 and stepped slot IV 17 are arranged on the main bearing outer ring II 7, seal ring IV 10 is located on the stepped slot III 16, stepped slot IV 17 is provided with the pressing plate II 9 to 10 pressuring actions of seal ring IV, pressing plate II 9 is fastened on the main bearing outer ring II 7 by bolt II 8, seal ring III 11 1 ends are fixed in the groove II 15, seal ring III 11 the other ends are close on pressing plate II 9 end faces, because the interaction between seal ring III 11 and pressing plate II 9 end faces, thereby make that seal ring IV 10 and outside air are isolated, seal ring IV 10 is closed in the lubricating grease system, is difficult for oxidized.
More than be a kind of mode of execution of the present utility model, a preferred demonstration example.The scope that the utility model patent application is asked for protection has more than and is limited to described mode of execution.All and technological scheme present embodiment equivalence all belongs to protection domain of the present utility model.
