Description
Technical field
The utility model relates to a kind of roller bearing, and specifically relate to a kind of high rotating speed lightweight roller bearing, it belongs to design bearing field.
Background technique
Current, in various equipment use field of bearings, common demands bearing reaches low noise, high rate performance, and especially in important precision instrument and equipment, low noise, high rotating speed become the most important thing of bearing quality requirement.The accurate pipe machine that twists adopts deep groove ball bearing structure originally always, but level of noise and turn up are less than client's usage requirement, become bearing technology blank spot, improve bearing structure, and raising bearing rotating speed and reduction noise are important technical tasks.
Summary of the invention
In view of the defect that prior art exists, the purpose of this utility model to provide a kind of high rotating speed lightweight roller bearing, it coordinates quantity mounting point to improve to the structure of bearing and rolling element, realize bearing lightweight requirements at work, improved the limit speed of bearing by the reduction of rolling element assembly rotary inertia, reduce bearing noise.
For achieving the above object, the technological scheme that the utility model adopts is a kind of high rotating speed lightweight roller bearing, and it comprises: outer ring, inner ring, retainer and rolling element; Retainer is placed between inner ring and outer ring; Described retainer comprises: retainer base, retainer upper cover and rivet, and retainer base and retainer upper cover are fixed as one by rivet; Described rolling element number is the half of retainer pocket hole number, and rolling element is evenly installed in retainer half pocket hole.
The pocket hole that described retainer does not install rolling element is oil storage pocket hole.
Bearing lubrication grease or vacant is provided with in described oil storage pocket hole.
Described retainer base is made up of pedestal and crossbeam, and pedestal and the contacting point, outer ring in oil storage pocket hole are provided with outer arc b, and itself and inner ring contacting point are provided with inner arc b, and inner arc b does not contact with bearing enclose with outer arc b; Crossbeam is provided with some through holes.
Described retainer base inner diameter is provided with 45 degree of groovings.
Described retainer upper cover oil storage pocket hole and contacting point, outer ring are provided with outer arc a, and itself and inner ring contacting point are provided with inner arc a, and inner arc a does not contact with bearing enclose with outer arc a.
Described inner arc a is equal with inner arc b radian, and the radian of described outer arc a and outer arc b is equal.
After adopting such scheme, compared with prior art there is following beneficial effect: bearing roller only needs the half of normal rolling element quantity, alleviates bearing weight, improve bearing limit speed, retainer internal diameter is provided with grooving structure, weight reduction, reduce frictional force, also make bearing rotating speed improve; In retainer pocket hole, be provided with oil storage pocket hole, ensure to obtain more excellent lubrication effect in rolling element running, not only improve bearing rotating speed, bearing working life can also be improved.Be proven, the cylinder rolling body bearing limit speed after improvement improves 50%, and working life improves 20%, meets the needs of customers.

Embodiment
For understanding this high rotating speed lightweight roller bearing further, be described as follows below in conjunction with accompanying drawing.
It comprises: outer ring, inner ring, rolling element, retainer base, retainer upper cover and rivet; Described rolling element number is the half of retainer pocket hole number, and rolling element is uniformly loaded in retainer pocket hole, namely fills a rolling element every a pocket hole, and second half pocket hole of retainer is vacant or take up bearing lubrication grease; Retainer base is connected together by rivet and retainer top cap, and rolling element and retainer being linked together becomes retainer assembly, and retainer assembly is put between bearing inner race and bearing outer ring.
Retainer has can fill the retainer pocket hole that rolling element again can be vacant, and half rolling element is contained in retainer half pocket hole respectively, and the retainer other half pocket hole that dress rolling element is adjacent is vacant or hold bearing dress lubricant grease.
Described retainer base base is provided with oil storage pocket hole outer arc and oil storage pocket hole inner arc, inner arc does not contact with bearing enclose with outer arc, reduce frictional force, be convenient to grease in bearing operation, enter interior raceway and outer raceway, remaining on can constantly to the rolling element oiling in retainer pocket hole in bearing operation; Retainer base inner diameter is provided with 45 degree of groovings, weight reduction and friction, reduces noise, improves rotating speed, improves bearing life.
Described retainer upper cover oil storage pocket hole and contacting point, outer ring are provided with outer arc a, and itself and inner ring contacting point are provided with inner arc a, and inner arc a does not contact with bearing enclose with outer arc a.
