Abstract
The present invention relates to the processing technology fields on retainer surface, more particularly to the processing method on bearing stamping retainer surface, leaching modeling processing is carried out to wind power bearing retainer surface with nylon material, improve the wearability of retainer, the present invention can reach the wearability of bearing retainer surface nitrocarburizing, while reduce the big harm easy to crack of retainer brittleness caused by nitrocarburizing.
Description
Technical field
The present invention relates to the processing technology fields on retainer surface, and in particular to the processing side on bearing stamping retainer surface
Method.
Background technique
It is all made of nitrogen-carbon cocementing process both at home and abroad before wind power bearing retainer, improves the wearability of retainer.The bearing
In use discovery often occur retainer due to nitrocarburizing brittleness cause greatly bearing retainer crack this harm with
Hidden danger.It needs to develop a kind of new method thus and replaces nitrogen-carbon cocementing process.For this purpose, invention is with a kind of leaching modeling of nylon material in wind
Electric bearing retainer surface method.
Summary of the invention
In view of the defect of the prior art, the present invention proposes the processing method on bearing stamping retainer surface, improves retainer
Wearability, the wearability of bearing retainer surface nitrocarburizing can be reached, while reducing guarantor caused by nitrocarburizing
Hold the big harm easy to crack of frame brittleness.
In order to achieve the above objectives, the technical scheme is that the processing method on bearing stamping retainer surface, uses Buddhist nun
Imperial material carries out leaching modeling processing to wind power bearing retainer surface.
Further, it the treating method comprises retainer before handling leaching modeling and carry out pretreatment and the pre-heat treatment, use Buddhist nun
Imperial material carries out leaching modeling, cooling, obtains retainer after leaching modeling processing.The retainer that leaching modeling will preheat is immersed in nylon material
In.
Preferably, nylon material is nylon material PA66.
Preferably, the pretreatment is Shot Blasting.
Preferably, the pretreatment temperature is 350 DEG C.
Preferably, it is described with nylon material carry out leaching modeling the time be 20 ~ 22 seconds.
Preferably, retainer cooling time is 10 ~ 12 minutes after leaching modeling.
To further explanation of the invention, with a kind of nylon material PA66 (France produces) leaching modeling in wind power bearing retainer
The wearability of retainer is improved on surface, can reach the wearability of bearing retainer surface nitrocarburizing, while reducing nitrogen carbon
The big harm easy to crack of retainer brittleness caused by permeation.
Beneficial effects of the present invention: improving the wearability of retainer, can reach bearing retainer surface nitrocarburizing
Wearability, while reducing the big harm easy to crack of retainer brittleness caused by nitrocarburizing.
Detailed description of the invention
Fig. 1 is nitrocarburizing retainer sample macroscopic view wear morphology；
Fig. 2 is that retainer sample macroscopic view wear morphology is moulded in present invention leaching；
Fig. 3 is nitrocarburizing retainer appearance after test；
Fig. 4 is leaching modeling retainer appearance after test.
Specific embodiment
Embodiment 1
The processing method on bearing stamping retainer surface carries out leaching modeling to wind power bearing retainer surface with nylon material PA66
Processing.
Further, it the treating method comprises retainer before handling leaching modeling and carry out pretreatment and the pre-heat treatment, use Buddhist nun
Imperial material PA66 carries out leaching modeling, cooling, obtains retainer after leaching modeling processing.
Preferably, the pretreatment is Shot Blasting.
Preferably, the pretreatment temperature is 350 DEG C.
Preferably, it is described with nylon material PA66 carry out leaching modeling the time be 20 ~ 22 seconds.
Preferably, retainer cooling time is 10 ~ 12 minutes after leaching modeling.
Implement performance:
1, leaching of the invention modeling retainer sample and nitrocarburizing retainer sample wear resistance comparative test:
1 experimental condition of table
2 check for wear result (mm) of table
Brief summary: as shown in figures 1 and 2, the wearing depth and width and nitrocarburizing retainer sample of leaching modeling retainer sample
Quite.
Specification leaching modeling retainer and nitrocarburizing retainer of the same race are chosen in a set of bearing respectively to load in bearing tester
Comparative test, with identical experimental condition come the accuracy of guarantee test.
Experimental condition: load operating 48 hours, drive manner are ± 20 ° and swing that swing speed is 1.5 revs/min
Clock.
Brief summary: the comparative test of this leaching modeling retainer and nitrocarburizing retainer is in 1 set of FL-HSB2421DFT bearing
Upper while progress, test has carried out 48 hours.It tears set after examination open to check, leaching modeling retainer pocket hole is without apparent abrasion, deformation, rolling
Road, steel ball surface no marking are pressed and are owed, and leaching modeling retainer moulds the polishing scratch light (good) of retainer in nitrogen carbon to abrasion, the leaching of steel ball
Permeation retainer, as shown in figures 3 and 4.
Conclusion: a kind of method of the nylon material leaching modeling on wind power bearing retainer surface reaches nitrocarburizing in wind power bearing
The performance requirement on retainer surface can soak method of the modeling on wind power bearing welding retainer surface with a kind of nylon material and replace
Nitrocarburizing welds retainer surface in wind power bearing.This method has been supplied in wind power bearing retainer production at present.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, this
Field technical staff makes a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all falls within this hair
In bright protection scope.
