Abstract
The utility model relates to a wind power generation bearing cage structure, which comprises a cage ring, and is characterized in that an arc-shaped pocket is formed radially along the circumference of the cage ring, a cylindrical roller is formed in the arc-shaped pocket, a plug corresponding to the cylindrical roller is arranged inside an outer diameter of the arc-shaped pocket, arc-shaped plates are arranged on the two end surfaces of the arc-shaped pocket, a rivet passes through the plug and a rivet hole and is fixedly connected with the cage ring, and small lug bosses are formed on both the contact surface of the arc-shaped pocket and the side surface of the cylindrical roller and the contact surface of the plug and the side surface of the cylindrical roller. The utility model has the advantage that a cage serves great effect for guiding the roller to run stably.
Description
Technical field
The utility model relates to a kind of retainer, particularly a kind of wind-power electricity generation bearing cage structure.
Background technique
Wind-power electricity generation is a kind of new energy form, because wind power plant work mistress is aerial outward, bearing complex operating environment, transforming to MW class owing to wind-power electricity generation simultaneously, the volume of wind power plant is also increasing, the supporting bearing size of using wind power plant is used in the large slewing bearing on the wind-power electricity generation spindle also increasing, and bearing outside diameter is about 1.7 meters.This wind-power electricity generation main shaft bearing is for connecting the important transmission part of fan blade rotary head and generator, be responsible for the generating of main engine power generation machine is passed in the rotation of wind energy, since bearing bear complicated radially, axially, heavy load such as tilting moment, since bearing bear complicated radially, axially, heavy load such as tilting moment, the bearing internal structure of wind-power electricity generation is the structure of three-row cylinder roller, therefore the retainer of existing ordinary construction can't be competent at, demands inventing a kind of retainer that can meet the requirement of wind-power electricity generation bearing urgently.
Summary of the invention
The purpose of this utility model be solve retainer of the prior art can't satisfy the on-stream suffered complexity of large diameter wind-power electricity generation bearing radially, axially, the problem of heavy load such as tilting moment, a kind of wind-power electricity generation bearing cage structure is provided.The utility model designs a kind of wind-power electricity generation bearing cage structure, comprise the maintenance bobbin, it is characterized in that: keeping bobbin to be processed with circular arc pocket hole diametrically along circumference, in circular arc pocket hole, cylindrical roller is arranged, there is plug relative in external diameter inboard, circular arc pocket hole with cylindrical roller, arc plate is respectively arranged on the both ends of the surface of plug, pass plug and keep the rivet hole on the bobbin to fixedly connected with keeping bobbin by rivet.Be processed with small boss on the contact plane of the surface of contact of circular arc pocket hole and cylindrical roller avris end face and plug and cylindrical roller avris end face.The utility model has the advantages that retainer to guide rolls smooth operation play very large effect.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Below in conjunction with accompanying drawing the utility model is elaborated
Embodiment
Comprise among the figure and keep bobbin 1, it is characterized in that: keeping bobbin 1 to be processed with circular arc pocket hole 2 diametrically along circumference, in circular arc pocket hole 2, cylindrical roller 3 is arranged, there is plug 4 relative in 2 external diameter inboards, circular arc pocket hole with cylindrical roller 3, arc plate 5 is respectively arranged on the both ends of the surface of plug 4, pass plug 4 and keep the rivet hole on the bobbin 1 to fixedly connected with keeping bobbin 1 by rivet 6.Be processed with small boss 7 on the contact plane of the surface of contact of circular arc pocket hole 2 and cylindrical roller 3 avris end faces and plug 4 and cylindrical roller 3 avris end faces.
Concrete used bearing is three organ timbering bearings, and radially load cylindrical roller is arranged in bearing inside, and the cylindrical roller of the axial load of two row is arranged, and retainer structure of the present utility model is axial load cylindrical roller retainer.Roller is evenly separated in acting as at circumferencial direction of this retainer, and guide rolls turns round according to raceway, because this bearing belongs to the huge revolving turntable bearing, end thrust roller cage outside dimension is greater than 1.5 meters, and belonging to the speed range of high speed rotating during bearing working, very large effect is played in the smooth operation of retainer guide rolls.
The cylindrical pocket hole that keeps bobbin along circumference in radially five equilibrium processing, cylindrical pocket depth is greater than cylindrical roller length, the plug of after cylindrical roller is packed cylindrical pocket hole into, in the pocket hole, packing into, rivet hole is arranged on the plug, on the corresponding with it retainer rivet hole is arranged also, using the arc lower plate then is fixed on plug in the cylindrical pocket hole with rivet, the contact plane of cylindrical pocket hole and cylindrical roller end face contact plane and plug is processed with small boss, cooperate with the cylindrical roller end face is intact, play the effect of reducing friction with the aimming circle cylinder roller.
Claims (2)
1, a kind of wind-power electricity generation bearing cage structure, comprise the maintenance bobbin, it is characterized in that: keeping bobbin to be processed with circular arc pocket hole diametrically along circumference, in circular arc pocket hole, cylindrical roller is arranged, there is plug relative in external diameter inboard, circular arc pocket hole with cylindrical roller, arc plate is respectively arranged on the both ends of the surface of plug, pass plug and keep the rivet hole on the bobbin to fixedly connected with keeping bobbin by rivet.
2, by the described a kind of wind-power electricity generation bearing cage structure of claim 1, it is characterized in that: be processed with small boss on the contact plane of the surface of contact of circular arc pocket hole and cylindrical roller avris end face and plug and cylindrical roller avris end face.
