Description
Technical field
The utility model is related to lubricating arrangement under a kind of bearer ring, and bearing mistake is lubricated under specifically a kind of staged ring
Cross set and its fuel feeding disk.
Background technology
Large-diameter high-speed bearings D N values are high, bear load greatly, itself produces amount of heat in operation process, for being operated in
Service life will be had a strong impact on for bearing in high-temperature service environment.The key measure of its high temperature problem is solved for bearing
It is exactly that bearing is carried out sufficiently to lubricate and cool down.In the past, high-speed bearing was generally using injection thin oil lubricant method, this lubrication
Method is lubricating oil to be injected into retainer at a certain angle from bearing face and lasso gap is lubricated to bearing.In high speed bar
Under part, influenceed by factors such as bearing arrangements, its lubricating efficiency is relatively low, it is impossible to sufficient lubrication and cooling.Occur because high-speed bearing loses
Caused by effect failure be often because high-speed bearing fuel feeding is not enough, lubricate and cool down it is insufficient cause, show high-speed bearing
One of whole equipment most weak link has been constituted, the service life of equipment has been had a strong impact on.
By contrast, lubricating method is using inertia is centrifuged, directly by lubricating oil via many being opened on inner ring under ring
Radial hole and spray to raceway face, the part of lubricating oil makees axially flowing along below inner ring and reaches the mesh of cooling inner ring
's.Lubricating oil into raceway is divided into left and right two passes and flowed outwardly, and in passing rushes the abrasive dust fallen from parts such as retainers
Brush off.This lubricating method with oil mass than oil jet lubrication much less, the power loss caused by the power stirring of oil
Few, the heat condition of bearing is also greatly improved, or even inner ring temperature is likely lower than outer ring and reduces bearing fault rate.But
Lack a kind of dismounting always in the prior art flexible, handling can be completed in the case where not damaging axle, and can effectively control
The splashing direction of lubricating oil, realizes lubricating arrangement under the bearing ring fully reclaimed to lubricating oil.
