The inventive bearing assembly is simple in structure, and can reduce mounting space and make the wind power generator unit structure compact.
Description
[technical field]
The present invention relates to a kind of bearing unit that connects high speed shaft and lower velocity shaft.
[background technique]
The transmission of high speed shaft 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.
[summary of the invention]
The objective of the invention is to overcome the deficiency of existing technology, provide a kind of simple in structure, can dwindle the connected high speed shaft of installing space and the bearing unit of lower velocity shaft.
In order to address the above problem, the present invention adopts following technological scheme:
A kind of bearing unit 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 bearing unit 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 bearing unit 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 bearing unit 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 bearing unit that connects high speed shaft and lower velocity shaft 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.
Aforesaid a kind of bearing unit that connects high speed shaft and lower velocity shaft is characterized in that: described first seal ring and second seal ring are backbone sealing ring.
Aforesaid a kind of bearing unit that connects high speed shaft and lower velocity shaft is characterized in that: described lower velocity shaft is a hollow shaft.
Aforesaid a kind of bearing unit that connects high speed shaft and lower velocity shaft is characterized in that: described link is a flange.
Beneficial effect of the present invention 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 a main sectional view of the present invention.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As shown in Figure 1, a kind of bearing unit that connects high speed shaft and lower velocity shaft is characterized in that: comprise link 1, link 1 is a flange, and flange is installed on the slip ring, and slip ring is to be responsible for the electric component that solid of rotation is communicated with, carries the energy and signal.Be set with bearing 2 on the link 1, link 1 one ends are provided with when being used to lower velocity shaft 3 and rotation are installed can drive the spacer 8 that link 1 rotates, and lower velocity shaft 3 is a hollow shaft, and lower velocity shaft 3 spacers 8 connect through bolt, and spacer 8 links 1 are through the bolt connection.Be set with bearing (ball) cover 4 on the outer ring of bearing 2; Bearing (ball) cover 4 one ends are provided with when being used to high speed shaft 5 and rotation are installed can drive the spacer ring 9 that bearing (ball) cover 4 rotates; Simultaneously high speed shaft 5 and spacer ring 9 are connected through bolt; Spacer ring 9 and bearing (ball) cover 4 are connected through bolt, spacer ring 9 one ends with the outer ring axial compression of bearing 2 on bearing (ball) cover 4.Spacer 8 and spacer ring 9 are located at the homonymy of bearing 2, and high speed shaft 5 is a hollow shaft, and lower velocity shaft 3 is located in the high speed shaft 5.Establish first seal ring 6 between spacer 8 and the spacer ring 9, be provided with second seal ring, 7, the first seal rings 6 between link 1 and the bearing (ball) cover 4 and second seal ring 7 is a backbone sealing ring.
