Description
Technical field
The utility model is related to field of bearings, and in particular to a kind of high-speed angular contact ball bearing.
Background technology
The angular contact ball bearing of high-speed sealing grease lubrication is widely used in various electro spindles, grease lubrication angular contact ball axis
It holds compared with the bearing of traditional fog lubrication, pollution of the grease lubrication angular contact ball bearing without mist of oil to electro spindle use environment,
The pressure gas source for eliminating mist of oil simultaneously, has saved the energy.The bearing of grease lubrication can just make always after being packed into lubricating grease
With certain with fat amount.The bearing of fog lubrication is very big to the consumption of oil.Existing angular contact ball bearing is architectural limitation, storage
Fat amount is few, restricts the service life of angular contact ball bearing, to affect the service life of electro spindle.
Utility model content
The purpose of this utility model is to provide a kind of high-speed angular contact ball bearing, is led less with the bearing depot fat amount for solving present
The technical issues of causing with short life.
To achieve the above object, the utility model high-speed angular contact ball bearing adopts the following technical scheme that：High speed Angular Contact Ceramic
Retainer, steel ball are equipped between ball bearing, including outer ring, inner ring, inner ring and outer ring, retainer is equipped with to be equal with steel ball number
Pocket hole, interior raceway groove is equipped on the outside of inner ring, outer raceway groove is equipped on the inside of outer ring, slope, slope and outer raceway groove mistake are equipped on the inside of outer ring
Cross connection, slope is equipped with grease storage groove, and grease storage groove is circular layout along outer ring inner peripheral surface, grease storage groove be arranged with outer raceway groove interval so that
It obtains and forms protection anchor ring between the two, sealing ring is also embedded between outer ring and inner ring, outer ring inside and inner ring outside are equipped with phase
The sealing card slot for installing the sealing ring answered.
Further, the part at left and right sides of the interior raceway groove of the inner ring is isometrical.
Further, the quantity in the pocket hole is 21.
Further, the retainer is outer guiding.
Further, a diameter of 11.906mm of the steel ball.
Further, the sealing ring includes sealing ring ontology, and sealing ring ontology, which has, to be arranged towards steel ball side
The periphery convex of cavity, sealing ring ontology is equipped with card body, and card body is packed into sealing card slot.
The beneficial effects of the utility model：The utility model is equipped with grease storage groove, grease storage groove on the slope on the inside of outer ring
It can be with storing lubricating grease；Be additionally provided with sealing ring between outer ring and inner ring simultaneously, sealing ring clamps setting, sealing ring and retainer it
Between form a more closed small space, lubricating grease is not easy to leak.In bearing working, lubricating grease can play good lubrication
Effect, extends the service life of angular contact ball bearing.Further, grease storage groove is circular layout along outer ring inner peripheral surface, grease storage groove
It is configured so that form protection anchor ring between the two with outer raceway groove interval, not only reduces difficulty of processing, moreover it is possible to prevent in processing
It forms sharper rib and influences the normal rolling of steel ball.
Description of the drawings
Fig. 1 is the structural schematic diagram (sectional view) of the utility model high-speed angular contact ball bearing；
Fig. 2 is the structural schematic diagram (removal sealing ring) of the utility model high-speed angular contact ball bearing.
Corresponding title is respectively marked in figure：1, inner ring, 2, steel ball, 3, retainer, 4, sealing ring, 5, grease storage groove, 6, outer ring,
