Technical Field

Background
The porous oil-containing retainer is widely applied to extreme working condition support bearings such as aerospace and the like, is not only a key moving part of the bearing, but also a carrier of lubricating oil, and determines the lubricating performance of the bearing under the working conditions of high speed, oil lacking and the like. The oil content of the oil-containing retainer is difficult to regulate in real time, and is mainly reflected in that when the porosity of the retainer is high, the strength and the antifriction property of the retainer material are reduced, and the oil retention rate is low; when the porosity is low, there are problems of low oil content, poor lubricating effect and the like. In addition, the lubricating oil in the pores of the porous retainer has the problems of insufficient amount and easy loss. For example, in 2002, a control force anti-gyro is seriously worn due to lubrication failure of a high-speed rotor, and finally, a bearing is blocked.
With the continuous expansion of the application condition of the rolling bearing, the problem of lubrication failure of the bearing retainer is paid more and more attention. For example, in chinese patent CN106050932A, "a bearing retainer", circular mounting holes and guide grooves are formed on the inner and outer sides of the retainer to guide lubricating oil for lubrication, and a micro humidity detector is disposed in the mounting holes to detect the degree of lubrication inside the bearing. Chinese patent CN100570165C 'manufacturing method of porous phenolic adhesive tape laminated retainer material for rolling bearing', uses foaming agent to form holes in resin curing to manufacture porous phenolic adhesive tape laminated retainer material with high porosity and oil content.
The lubricating effect of the bearing retainer is greatly improved, the reliability of the bearing is improved, but the problem that the oil content is difficult to regulate and control in real time along with the working condition still exists for the oil-containing retainer, the lubricating oil in the retainer is insufficient, the lubricating oil is lost and is high in speed, the oil content and the oil retention rate in the retainer are difficult to achieve the two-fold defect, and the like. How to achieve high oil content, high oil retention rate, good mechanical property and good processing manufacturability becomes a bottleneck problem restricting the development of the ultra-high speed shaft bearing.

and thirdly, when the excessive lubricating oil of the bearing retainer 1 is detected, the current in the coil 2 is reduced, the magnetic field generated by the coil is reduced, the axial direction of the bearing retainer 1 is reduced, the excessive lubricating oil is sucked, and the utilization rate of the lubricating oil in the retainer is improved.
The magnetostrictive porous material has certain pores, and the porosity is more than 20%.
Compared with the prior art, the invention firstly utilizes the magnetostrictive effect to regulate and control the oil yield of the porous oil-containing retainer of the bearing, and can solve the problem that the porosity and the oil retention rate of the porous retainer at home and abroad are difficult to be both complete at present; firstly, the axial size of the bearing porous retainer can be controlled by controlling the magnetic field intensity through current; secondly, the oil yield of the porous retainer of the bearing is controlled by the deformation of the magnetostrictive material; the problems of insufficient lubricating oil of the bearing and failure of the retainer are solved, the utilization rate of the lubricating oil is improved, and the service life of the bearing is prolonged.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 2, a method for regulating and controlling the lubricating performance of a porous retainer of a bearing by utilizing a magnetostrictive effect comprises the following steps:
referring to fig. 1, fig. 1 is a schematic view of installation of equipment used in the present invention, and includes a bearing outer ring 3, balls 4 and a bearing inner ring 5 of a bearing, a plurality of groups of coils 2 are arranged on a bearing seat, and a bearing retainer 1 is made of magnetostrictive porous material;
referring to fig. 1, when the content of the lubricating oil in the bearing retainer 1 is detected to be low, the current in the coil is increased, a stable axial magnetic field is formed around the bearing retainer 1 at the moment, the magnetic field intensity is increased, referring to fig. 3, the bearing retainer 1 is axially extended, the porous structure of the bearing retainer 1 is deformed, and the lubricating oil in the bearing retainer 1 is squeezed out like water in a wrung sponge, so that the lubricating effect of the bearing retainer 1 is improved;
thirdly, when the excessive lubricating oil of the bearing retainer 1 is detected, if the excessive lubricating oil is not recycled, the lubricating oil is wasted and polluted. At the moment, the current in the coil is reduced, the magnetic field generated by the coil is reduced, the axial direction of the bearing retainer 1 is reduced, the bearing retainer 1 sucks redundant lubricating oil like a sponge water absorption principle, and the utilization rate of the lubricating oil in the retainer is improved.
The magnetostrictive porous material has certain porosity which is more than 20 percent and is described in the literature, "preparation and performance research of Tb-Dy-Fe magnetostrictive material", and the main preparation method comprises the following steps:

(2) casting the alloy liquid into a mould to obtain a TbDyFe alloy ingot;
(3) crushing and ball-milling the alloy ingot to obtain alloy powder;
(4) uniformly mixing the alloy powder with a pore-forming agent (pore-forming agent M2 of Tianjin chemical reagent Co., Ltd.), wherein the content of the pore-forming agent is 5% of the total mass, orienting in a magnetic field and pressing for molding;
(5) and sintering the sample, and removing the pore-forming agent to obtain the magnetostrictive porous material.
According to the invention, through the bearing retainer 1 with the magnetostrictive positive effect, under the effect of the magnetostrictive positive effect caused by an external magnetic field, axial telescopic deformation can occur, so that the porosity and the retainer oil output are changed, namely under the high-speed heavy-load working condition, the bearing is not lubricated enough, the friction heat of the bearing retainer 1 and the balls 4 is increased, and at the moment, the porosity is regulated and controlled by the magnetic field intensity of the bearing retainer 1 by changing the current intensity of a plurality of groups of coils 2, so that the bearing retainer 1 made of magnetostrictive materials produces more oil; under the working conditions of low speed, light load and the like, the magnetostrictive material bearing retainer 1 produces less oil by changing the magnetic field.
