Abstract
The invention provides a high-speed angular contact ball bearing retainer. A ring-shaped groove is opened on a guide surface 6 of a retainer 1, as shown in the figure 5. The performance of the original structure is not affected by the ring-shaped groove of the retainer; however, space is left around a bearing roller steel ball 3 so as to better the lubricating performance. Oil or oil mist has better lubricating and cooling performance, for the flow of the oil or the oil mist is smoother when in use for lubricating. When grease is used for lubricating, space for storing the grease is increased, after rotating and running-in of the bearing, the grease storage is even more when a grease channel is formed, and the lubricating life of the bearing is prolonged, thereby prolonging service life of the bearing. After the ring-shaped groove is opened on the outer diameter of the retainer, the weight is lessened, the moment of inertia is reduced and the rotation of the bearing is more flexible.
Description
Affiliated technical field
The present invention relates to technical field of bearings, especially a kind of high-speed angular contact ball bearing cage.
Background technique
At present, the retainer of general high-speed angular contact ball bearing is to make with phenolic aldehyde lamination stringing or bronze, and its structure is a ring, radially has the pocket hole of several dress steel balls, between bearing outer ring internal diameter and the retainer external diameter guide clearance is arranged, and makes retainer and bearing concentric.This structure has its advantage, but owing to be the outer ring guiding, the less shortcoming that produced again of guide clearance, new structure retainer of the present invention keeps the advantage of original structure, can overcome the shortcoming of original structure again.
Summary of the invention
After general high-speed angular contact ball bearing adopted the outer ring guide structure, guide performance improved, and when bearing adopts oil lubrication or oil mist lubrication, helped oiling agent and flowed into, and is favourable to bearing lubrication, cooling.But,, can make the interior grease of bearing extrude the reduction bearing lubrication life-span during bearing high speed rotating because retainer 1 is very little with guide clearance 4 numerical value between the outer ring 2 if when use grease lubrication.The present invention proposes the advantage of the existing original structure of retainer of new structure, and the greasy property in the time of can improving grease lubrication again improves bearing life.
Technological scheme provided by the invention is, the structural feature of new structure retainer is to have a circular groove on the guide surface 6 of retainer 1, shown among the figure 5, retainer has the performance that does not influence original structure behind this circular groove, but around bearing roller steel ball 3, reserved the space, made the greasy property of bearing better.During with oil or oil mist lubrication, oil or mist of oil flow, and Chang is logical more, and is lubricated, cooling performance is better.Increased the space of storage grease during with grease lubrication, the grease of storing when forming the grease channel after the bearing rotation running-in is more, prolongs the lubricating life of bearing, thereby prolongs the working life of bearing.Have weight saving behind the circular groove on the retainer external diameter, rotary inertia reduces, and makes the bearing rotation more flexible.

Embodiment
Specific embodiments of the present invention is to have oil storage tank on the external diameter guide surface of retainer.Groove width should be greater than steel ball size, but can not influence the guide performance of guide surface.Groove depth should be greater than 1mm, otherwise influences improvement effect.Added the intensity that to check retainer behind the oil storage tank,, can increase the wall thickness of retainer according to the material therefor difference.The retainer of this band oil storage tank can be used in the high speed angle contacting ball-joint and high speed deep groove ball bearing of other structural type of what.
