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]
There is in some cases the transmission of high speed shaft and lower velocity shaft, particularly in wind power generating set simultaneously.In the prior art, high speed shaft and lower velocity shaft are realized transmission by two or more sets connection parts respectively, take up room larger while being arranged on like this in wind-power electricity generation group, and structure is compact not, and adopt many group connection parts will improve cost of production.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, 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 by the following technical solutions:
A kind of bearing unit that connects high speed shaft and lower velocity shaft, it is characterized in that: comprise link, on described link, be set with bearing, described link one end is provided with the spacer of the link rotation described in driving when lower velocity shaft being installed and being rotated, on the outer ring of described bearing, be set with bearing (ball) cover, described bearing (ball) cover one end is provided with the spacer ring of the bearing (ball) cover rotation described in driving when high speed shaft being installed and being rotated.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: described spacer and spacer ring are located at the homonymy of described bearing, and described high speed shaft is hollow shaft, and described lower velocity shaft is located in described high speed shaft.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: described link and spacer are bolted, and spacer and lower velocity shaft are bolted.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: bearing (ball) cover and spacer ring are bolted, spacer ring and high speed shaft are bolted.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: between described spacer and described spacer ring, establish the first seal ring, between described link and described bearing (ball) cover, be provided with the second seal ring.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: the first described seal ring and the second seal ring are backbone sealing ring.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: described lower velocity shaft is hollow shaft.
A kind of bearing unit that connects high speed shaft and lower velocity shaft as above, is characterized in that: described link is flange.
Beneficial effect of the present invention has: high speed shaft is arranged on spacer ring, and lower velocity shaft is arranged on spacer, thus the transmission simultaneously of the high speed of realization and low speed, and do not need Duo Zu mechanism to connect respectively high speed shaft and lower velocity shaft, simple in structure, installation cost is low; Lower velocity shaft is located in hollow high speed shaft, has further dwindled installing space, makes compact structure; Lower velocity shaft is hollow, and lubricant oil conveyance conduit can be installed like this in lower velocity shaft, so just, without designing other lubricant oil conveyance conduit, dwindles installing space again.
[accompanying drawing explanation]
Fig. 1 is 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 flange, and flange is arranged on 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.On link 1, be set with bearing 2, link 1 one end be provided with for install lower velocity shaft 3 and rotate time can drive link 1 to rotate spacer 8, lower velocity shaft 3 is hollow shaft, lower velocity shaft 3 spacers 8 are bolted, spacer 8 links 1 are bolted.On the outer ring of bearing 2, be set with bearing (ball) cover 4, bearing (ball) cover 4 one end be provided with for install high speed shaft 5 and rotate time can drive bearing (ball) cover 4 to rotate spacer ring 9, high speed shaft 5 and spacer ring 9 are bolted simultaneously, spacer ring 9 and bearing (ball) cover 4 are bolted, spacer ring 9 one end by 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 hollow shaft, and lower velocity shaft 3 is located in high speed shaft 5.Between spacer 8 and spacer ring 9, establish the first seal ring 6, between link 1 and bearing (ball) cover 4, being provided with the second seal ring 7, the first seal rings 6 and the second seal ring 7 is backbone sealing ring.
When use, lower velocity shaft 3 is to be driven and rotated by generator blade, lower velocity shaft 3 drives spacer 12, adpting flange 11 to rotate together with bearing 2 inner rings while rotation, high speed shaft 5 drives while rotation together with the outer ring of spacer ring 9, bearing (ball) cover 4 and bearing 2 and rotates, and what high speed shaft 5 connected is gear-driven variable-speed motor structure.And lower velocity shaft 3 is also hollow, can in lower velocity shaft 3, establish lubricant oil conveyance conduit or electric wire etc., reduce like this installing space.
