Abstract
The utility model relates to a novel bearing component capable of connecting a high speed shaft and a low speed shaft. The technical key points are that the bearing component comprises a connecting piece, wherein the connecting piece is sleeved with a bearing; a spacer bush which is used for accommodating the low speed shaft and can drive the connecting piece to rotate when rotating is arranged at one end of the connecting piece; an outer ring of the bearing is sleeved with a bearing end cover; a spacer ring which is used for accommodating the high speed shaft and can drive the bearing end cover to rotate when rotating is arranged at one end of the bearing end cover; the spacer bush and the spacer ring are arranged on the same side of the bearing; the high speed shaft is a hollow shaft; and the low speed shaft is arranged in the high speed shaft and is a hollow shaft. The bearing component has a simple structure, a mounting space can be reduced when the bearing component is mounted, and a wind generating set has a compact structure.
Description
[technical field]
The utility model relates to a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft.
[background technique]
The transmission of high speed and lower velocity shaft is arranged in some cases simultaneously, particularly in wind power generating set.In the prior art, high speed shaft and lower velocity shaft are realized transmitting through two or more sets connection parts respectively, and it is bigger to take up room when being installed on the wind-power electricity generation group like this, and structure is compact inadequately, and adopt many group connection parts will improve cost of production.
[model utility content]
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of simple in structure, the connected high speed shaft that can dwindle installing space and the novel bearing assembly of lower velocity shaft are provided.
In order to address the above problem, the utility model adopts following technological scheme:
A kind of novel bearing assembly that connects high speed shaft and lower velocity shaft; It is characterized in that: comprise link; Be set with bearing on the described link; Described link one end is provided with when being used to install lower velocity shaft and rotation can drive the spacer that described link rotates, and is set with bearing (ball) cover on the outer ring of described bearing, and described bearing (ball) cover one end is provided with when being used to install high speed shaft and rotation can drive the spacer ring that described bearing (ball) cover rotates.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft, it is characterized in that: described spacer and spacer ring are located at the homonymy of described bearing, and described high speed shaft is a hollow shaft, and described lower velocity shaft is located in the described high speed shaft.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft, it is characterized in that: described link is connected through bolt with spacer, and spacer is connected through bolt with lower velocity shaft.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft, it is characterized in that: bearing (ball) cover is connected through bolt with spacer ring, and spacer ring is connected through bolt with high speed shaft.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft; It is characterized in that: establish first seal ring between described spacer and the described spacer ring; Be provided with second seal ring between described link and the described bearing (ball) cover, described first seal ring and second seal ring are backbone sealing ring.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft, it is characterized in that: described lower velocity shaft is a hollow shaft.
Aforesaid a kind of novel bearing assembly that connects high speed shaft and lower velocity shaft, it is characterized in that: described link is a flange.
The beneficial effect of the utility model has: high speed shaft is installed on the spacer ring, and lower velocity shaft is installed on the spacer, thus the transmission simultaneously of the high speed of realization and low speed, and do not need the mechanisms that organize not connect high speed shaft and lower velocity shaft respectively more, simple in structure, installation cost is low; Lower velocity shaft is located in the hollow high speed shaft, has further dwindled installing space, makes compact structure; Lower velocity shaft is hollow, can the lubricant oil conveyance conduit be installed in lower velocity shaft like this, so just need not to design other lubricant oil conveyance conduit again, dwindles installing space.
[description of drawings]
Fig. 1 is the main sectional view of the utility model.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
