Abstract
The invention discloses a novel wind power generator paddle changing sliding bearing belonging to the field of wind power generators and bearings. The sliding bearing is composed of an outer sleeve 1, an outer sleeve 2 and an inner sleeve 3, wherein the outer sleeves are fixed on a hub, and the inner sleeve is connected with a paddle; a layer of antiwear self-lubricating composite material is arranged between inner and outer bearing sleeves and is bonded on inner cavities of an the outer sleeve 1 and an outer sleeve 2, the antiwear self-lubricating composite material and the inner sleeve form a sliding pair. The novel wind power generator paddle changing sliding bearing is mainly characterized in that the inner sleeve of the sliding bearing is driven through a gear, the angle of a wind turbine blade is changed, and the powder of a wind driven generator is adjusted.
Description
Patent type: invention
Applying unit: Hadian Generating Equipment State Engineering Research Center Co., Ltd.
Technical field:
The invention belongs to bearing and manufacturing field, is a kind of wind generating set pitch control sliding bearing structure design and manufacture method.
Background technique:
At present, the Large-scale Wind Turbines pitch variable bearings all adopts traditional rolling bearing both at home and abroad.
The problem that prior art exists:
Wind power generating set works under land and the maritime environment high altitude conditions, unmanned.Pitch variable bearings is the critical component of wind-powered electricity generation unit, and deadweight and centrifugal force that it bears tens meters linear leaf parts transmit wind load, and pushing generator rotates.Under the wind load action of different wind speed and directions, pitch variable bearings band moving vane changes the angle of attack during unit operation, changes pneumatic power.Regulating electric machine power, when wind speed oversteps the extreme limit wind speed, the feathering brake.Pitch variable bearings bears larger dynamic load and centrifugal force, but it transfers the oar operating time not long.The conventional rolling bearing that problem (1) prior art adopts, the manufacturing cycle is long, and the process equipment required precision is high, and cost is higher.The rolling bearing of problem (2) prior art because its structure determines it is a contact is had relatively high expectations to bearing intensity, not only strengthens the weight of fitted position but also increase unit.
The object of the invention:
The present invention solves the existing problem of prior art, invents a kind of wind generating set pitch control self-lubricating plain bearing, improves the safety reliability of wind electricity pitch variable bearings operation, prolongs maintenance cycle, improves its working life, reduces cost.
Technical solution of the present invention:
The present invention relates to a kind of wind generating set pitch control sliding bearing and manufacture method.Its feature: bearing is comprised of inner ring (1), outer ring (2), outer ring (3).The bearing general structure is to opening structure, bearing assemble form and deciding.The outer ring inside diameter surface is covered with antifriction, abrasion-proof self-lubricating composite material as the surface friction material; The external diameter of inner ring is the conical surface; With the outer ring internal diameter conical surface sliding pair that partners, has aligning function; The outer ring is provided with accumulator with storing lubricating grease, and the relative inner ring of accumulator is open architecture, and forms Seal cage between the inner ring, and bearing directly contacts with lubricating grease.The adsorption effect at friction pair interface and the viscosity effect of lubricating grease during the sharf rotation carry out long-acting lubricated to the sliding friction surface.
Scheme 2, outer ring inside diameter surface are covered with antifriction, abrasion-proof self-lubricating composite material as the surface friction material.Making matrix with the metal outer ring, is the surface friction layer at its surface binded phenolic aldehyde laminated cloth plate material, and its thickness is 1.5～4mm, and microcephaly's width optical axis holds width and decides.
The present invention is compared with the prior art:
1, have long-acting reliable oil lubrication characteristics, maintenance cycle is long, and bearing capacity is high, and bearing is safe and reliable to operation;
2, interior rubbing surface of the present invention has good self-lubricating property, even the non lubricant oil situation appears in the friction pair interface, bearing also can work;
3, simple in structure, volume is little, lightweight, easy installation and removal, the characteristics such as low cost of manufacture.
4, structural composite material uses the specific process bonding, guarantees the working life in 20 years.
Annotate: the content of patent protection: bearing structure and manufacture method
Description of drawings: Fig. 1 is the bearing structure schematic diagram.
Embodiment: bearing internal external sleeve is by the Chilled Hardened Steel manufacturing, and machine adds the bonding wearing layer composite material of rear overcoat.After machine adds or grinds, assembling.
Claims (3)
1. construction design of journal bearings.
2. high-abrasive material selection and adhesive method.
3. bearing manufacture method.
