Description
Technical field
The utility model is related to technical field of bearings, and in particular to a kind of 4 angular contact ball bearings of biserial.
Background technology
At present, the structure of two-row ball bearing is as shown in Figure 1, generally comprised inner ring 1, outer ring 2 and steel ball 3, the steel ball 3
Be arranged between inner ring 1 and outer ring 2, be correspondingly arranged on the inner ring 1 and outer ring 2 with 3 matched raceway of steel ball, it is but existing
Raceway to be arc-shaped, each raceway is actual after coordinating with steel ball 3 only to abut there are one 4 formation of point are tangent, so as to cause existing
The radial direction bearing capacity of two-row ball bearing is poor.In addition, there is also rooms for improvement for the sealing performance of existing two-row ball bearing.
The content of the invention
In view of the deficiencies of the prior art, the utility model provides that a kind of radial direction bearing capacity is more preferable and sealing performance is more preferable
4 angular contact ball bearings of biserial.
To achieve the above object, the utility model provides a kind of 4 angular contact ball bearings of biserial, includes inner ring, outer
Circle and steel ball, the steel ball are arranged between inner ring and outer ring, are correspondingly arranged on the inner ring and outer ring and are engaged with steel ball
Raceway, each raceway is made of two and half raceways, and two and half raceways are symmetrical set, and every section of half raceway is and steel ball shape
Into tangent abutting, sealing device is additionally provided between the inner ring and outer ring, and the sealing device is corresponded to and is located on the outside of steel ball,
The sealing device includes sealing ring and metal outer frame frame, and the section of the metal outer frame frame is closed for radial outer end and radial direction
The Jiong word shape structure of interior end opening is correspondingly provided with the slot of the radial outer end insertion for metal outer frame frame, metal outer frame on outer ring
Radially-inwardly concave groove is additionally provided in the middle part of the radial outer end of frame, the rolling being in contact with outer ring is equiped in the groove
Ball, sealing ring are installed in metal outer frame frame, and the radial inner end of sealing ring is contacted with inner ring formation, the radial outer end of sealing ring with
Spring is provided between the radial outer end of metal outer frame frame.
The beneficial effects of the utility model are：Using the above structure, due in the utility model each raceway be by two
Half raceway of section is formed, and every section of half raceway formed with steel ball it is tangent abut, therefore actual there are two points for each raceway after coordinating
It is contacted with steel ball formation, while raceway is both provided on inside and outside circle, therefore each is really 4 points between steel ball and inside and outside circle
Contact, so compared with prior art, the radial direction bearing capacity of bearing will be substantially improved.In addition, since the sealing device uses
Sealing ring and metal outer frame frame are formed, and metal outer frame frame is wrapped in outside sealing ring, so as to greatly promote the entirety of sealing device
Rigid；And spring is provided between the radial outer end of sealing ring and the radial outer end of metal outer frame frame, then it can be in spring
Under effect, sealing wear face is supplemented well, so as to greatly promote the sealing performance of bearing；In addition, in the footpath of metal outer frame frame
Middle part is additionally provided with radially-inwardly concave groove outward, and the steel ball being in contact with outer ring is equiped in the groove,
Outer ring is then contributed to preferably to be rotated relative to inner ring, so that bearing operation is more smooth.
The utility model can be further arranged to the spring positioning and clamp on the surface of the recesses.In this way, existing
Good stationary positioned is formed in some structures to spring.
The utility model may further be provided as the radial outer end of the metal outer frame frame and be plugged with it outer
It is swallowtail-shaped structure to enclose slot.It is assembled in this way, metal outer frame frame can be enable to form more reliably positioning with outer ring.
