Background technique
Rolling bearing retainer in other words portion's section of rolling bearing retainer is used to be kept by rolling element in rolling bearing or guide between an inner ring and an outer shroud.Usually a kind of lubriation material or lubricating grease are loaded the inner space of bearing in other words between inner ring and outer shroud to carry out bearing lubricating.But this consequence caused is, lubriation material or lubricating grease grease are present in some region of bearing (and these regions do not need lubricated) in whole life cycle, and importantly can not participate in rolling element lubrication when bearing working.Such as untapped lubriation material is gathered in a region of bearing interior space usually, and this region does not need lubricated.Such as be used on the many rows bearing on LKW wheel bearing unit, such region is such as positioned at the centre of the first and second raceways and Sealing in other words before guide lip (TRB guide lip).
In addition lubriation material is positioned on the working surface of inner ring or outer shroud or rolling element or rolling surface or the component contact of lubricating grease and relative movement, the result that such as may cause with the contact of rolling element is, require that lubriation material is subject to stress mechanically, such as, be extruded and/or kneading.Thus can such as in lubriation material itself and/or the increase or the heating that cause friction in rolling bearing.This such as may cause lubriation material and/or rolling bearing to be heated.
Possibility Change Example is as damaged or reducing the greasy property of lubriation material and/or the working life of bearing thus.
In traditional embodiment, need to tolerate that the lubriation material of some or grease are not used usually used as the drawback that must exist, they are inoperative is received in bearing.Be in bearing motion use in other words in or the oil quantity that carrying out lubricating in traditional embodiment, enough realize needed for bearing and/or desired working life.But may load within the bearing than actual required more lubriation material for this reason.
Therefore need to improve rolling bearing.
Summary of the invention
This demand meets by a kind of rolling bearing retainer or for portion's section of rolling bearing or a kind of rolling bearing.
Some embodiments relate to a kind of rolling bearing retainer or the portion's section for rolling bearing retainer, it is designed at least one rolling element of rolling bearing to remain in rolling element region, wherein, rolling bearing retainer or portion's section have lubriation material storage area.Lubriation material storage area is designed to the lubriation material holding paste, thus the rolling element region of lubriation material and rolling bearing retainer and/or the working surface of rolling element are kept at intervals when rolling bearing rotates.Lubriation material storage area has at least one opening, and the Lubricants of discharging from lubriation material under the effect of power and/or temperature variation can be flowed out towards rolling element region by described opening.
The lubriation material of paste can be any one lubriation material or the material under common bearing operating temperatures with very large viscosity, thus lubriation material has the shape of the viscous of paste and keeps sticking or adhering to, be i.e. such as non-liquid in lubriation material storage area.An example of the lubriation material of this paste is lubricating grease.Lubricating grease can such as comprise lubricant oil and condensed matter, such as salt, bentonite clay, polyurea materials, light metal, alkali metal soap and/or PTFE.Lubricating grease can have the condensed matter of lubricant oil, the approximately 5-10% of about 80% and the affix of about 10-15%.Concentrate can such as form spongiform lattice, and it surrounds the oil droplet of lubricant oil.By such as friction and extruding lubricating grease or the lubriation material of paste between the parts moved relative to one another, can such as gradually make lubricant oil in other words oil droplet be discharged on surface to be lubricated.This process is such as also referred to as " dialysis ".
The working surface of the lubriation material of paste and the rolling element region of rolling bearing retainer and/or rolling element keeps interval such as can mean, under the installment state of roller holder, the solid constituent element of lubriation material does not produce with rolling element to contact and do not arrive in rolling element region in other words.So such as can avoid the contact of the working surface of lubriation material and rolling bearing, rolling bearing retainer can be arranged in rolling bearing.
Lubriation material discharges Lubricants under force, and this power can be that each is suitable for realizing the power of above-mentioned " dialysis ", and such as centrifugation power or centrifugal force, they act on lubriation material when bearing working.Lubriation material can discharge Lubricants under the effect of temperature variation, and temperature variation here can be the temperature variation that each is suitable for realizing discharging Lubricants.Such as temperature variation is that temperature raises.
The opening of lubriation material storage area can be that any one is positioned at the opening on any direction and has arbitrary shape on any side of lubriation material storage area.Such as lubriation material storage area can be opened at least one direction completely.Can realize thus easily for lubriation material is filled in lubriation material storage area.The opening that such as Lubricants therefrom flows out is the same opening for lubriation material storage area filling lubriation material.This outward opening such as can not have closure member.Such as opening has clear width, its at least corresponding ratio of 0.1,0.2,0.5,0.8 or the whole width of lubriation material storage area and/or clear width.Opening can not be such as a part for paste structure or pore.This outward opening is designed to lubriation material directly and is not detoured in certain embodiments, namely flows out to rolling element region with the shortest path.
