Description
Technical field
This utility model belongs to the main shaft bearing technical field of sealing technology of wind-driven generator, is specifically related to a kind of mainshaft bearing of wind-driven generator sealing device.
Background technology
At present, wind power generating set generally mainly includes wind energy conversion system, gear-box, electromotor, controller and structural member etc., and the poor sealing of the main shaft bearing of the wind-driven generator of MW class, when wind-driven generator works time, friction is there is, it is necessary to inject lubricating oil, but the Leakage of lubricating oil is commonplace between bearing and bearing block, and the pollutant such as the dust in the external world also can enter into bearing, affect the service life of bearing; Furthermore, environment can be caused certain pollution by the lubricant grease of leakage, if oil leak also can threaten the life security of fan repair personnel to the ladder of tower. Additionally the metal structure of wind-driven generator due to for a long time exposed outside, it is easy to causing that it corrodes, once corrosion of metal structure is serious, maintenance difficulty is big, cost is high, the generator performance effect that impact is overall.
How can create a kind of good sealing effect, simple in construction, change easily, and the main shaft bearing sealing device of the little wind power generating set of required requirements of installation space, be one of the important research and development problem of current this area.
Utility model content
The purpose of this utility model is in that to solve problems of the prior art, it is provided that a kind of good sealing effect, simple in construction and the mainshaft bearing of wind-driven generator sealing device being easily changed.
In order to solve above-mentioned technical problem, this utility model is accomplished by:
A kind of mainshaft bearing of wind-driven generator sealing device, including port cap I, main shaft bearing, rolling element, bearing block, port cap II and port cap installing hole, described port cap I and port cap II is bolted on bearing block by port cap installing hole, main shaft bearing is arranged on inside bearing block, the first half of main shaft bearing offers upper groove, its the latter half offers low groove, described rolling element is arranged in the accommodating grooves of upper groove and low groove composition, the sealing ring with sealing function it is provided with between described port cap I and port cap II and axle sleeve, described bearing block includes bearing block body, bearing mounting base, installing hole and tank filler sleeve, described bearing mounting base is symmetrically arranged at bearing block body both sides, bearing mounting base is provided with multiple installing hole, the outer surface of upper of bearing block body offers tank filler sleeve.
Further, the outer surface of described main shaft bearing and bearing block is provided with anticorrosive coat, and described anticorrosive coat includes epoxy zinc rich primer layer, epoxy micaceous iron intermediate primer layers and fluorine carbon finishing paint layer from the inside to the outside.
Further, described sealing ring is trapezoidal O-ring seal and O type O-ring seal.
Described rolling element is double-row conical.
Preferably, described tank filler sleeve is arranged in the groove of bearing block body upper part outer surface.
Compared with prior art, this utility model has the advantages that the mainshaft bearing of wind-driven generator sealing device that this utility model provides passes through unique structural design, solve the thickness low LCL because of outer seal ring, the technical problem of rubber seal can not be installed, achieve application industrially, be provided that better seal effect; On bearing, it is provided with anticorrosive coat, it is ensured that the safe and stable operation of main shaft bearing simultaneously.
