Description
Technical field:
The utility model relates to a kind of wind-powered electricity generation set main shaft bearing, especially a kind of simple in structure, easy installation and removal, cost are low, can avoid unbalance loading and can bear bigger multidirectional load, wind-powered electricity generation set main shaft three-dimensional safe and reliable, long service life makes up self-lubricating plain bearing.
Background technique:
The wind-powered electricity generation unit is a kind of power generating equipment in aloft work, and its main shaft bearing is one of critical component of unit.Wind-powered electricity generation set main shaft bearing is except the deadweight of bearing rotating parts such as wheel hub with under the wind-force effect axially the positive-reverse thrust, also to bear between wheel hub and the bearing formed tilting moment load under wheel hub deadweight and wind-force effect, so the wind power principal axis bearing is to move under multidirectional stressed operating mode.Existing high-capacity direct-driving or semi-directly driven wind-powered set main shaft bearing is all selected rolling bearing for use and for single shaft holds supporting structure, bear bigger axial load in order to satisfy generally adopts cylindrical rolling body, has following shortcoming:
1. when cylindrical rolling body moved in a circle, causing rolling element because of the linear velocity at two ends is different was not PURE ROLLING, produces thus to be detained between blocked portion and the friction pair slippage takes place; Because of rolling element, Internal and external cycle are rigidity, can not correct the unbalance loading situation of tumbling and producing because of main shaft, cylindrical rolling body is operated under the unbalance loading operating mode; Two kinds of phenomenons have all increased surface friction drag and have accelerated rolling element and the wearing and tearing of raceway groove, and bearing is short working life.
2. because rolling bearing does not have good anti-seismic performance, under the wind-force effect, produce vibrations easily and bear bigger impact load, again because the actual bearer of rolling bearing is a contact or line contact, so tired conquassation fragmentation easily takes place when bearing the greater impact load rolling element, the bearing reliability is low;
3. when the wind-powered electricity generation unit opens, shutdown or slow-speed of revolution operation, fricting working surface can not effectively be set up the hydrodynamic lubrication oil film and when being in boundary lubrication even dry friction, adhesive wear will take place between friction pair, and bearing very easily damages;
Complex structure, volume weight big, trouble, cost height be installed.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, provide a kind of simple in structure, install easily, cost is low, can avoid unbalance loading and can bear bigger multidirectional load, wind-powered electricity generation set main shaft three-dimensional safe and reliable, long service life makes up self-lubricating plain bearing.
Technical solution of the present utility model is: a kind of wind-powered electricity generation set main shaft three-dimensional combination self-lubricating plain bearing, outer ring and inner ring are arranged, between outer ring and inner ring, there is polylith equally distributed radially watt, axially be connected to inside left thrust ring in the left side with described outer ring, be connected to inside right thrust ring with axial right side, described outer ring, between a left side thrust ring and the inner ring and be equipped with end thrust that polylith evenly arranges watt between right thrust ring and the inner ring, described radially watt watt have the lubrication channel that is communicated with end thrust, and described lubrication channel communicates with oil hole.
Described oil hole is the endoporus of right thrust ring, the endoporus of described left thrust ring and inner ring slide and join, there is Sealing the slip connecting part, the spacing of described polylith between radially watt is 5～100mm, spacing between the described polylith end thrust watt is 5～100mm, is provided with oil retaining edge at a watt spacing place and end thrust watt spacing place radially.
