Abstract
The utility model provides a multiseriate does not have full ball self -aligning bearing of holder, includes the outer lane, and inner circle and ball ring, ball ring are arranged by a plurality of ball and are constituteed, and the ball ring is located between outer lane and the inner circle, is provided with ring groove on the outer peripheral face of inner circle, and the ball encircles and is located ring groove, ball ring have two at least, the quantity of ball ring the same with ring groove's quantity, the ball completely adorn in ring groove, the ball be spherical or cylindrical, the utility model discloses can satisfy the different demands of all kinds of host computers of working under the various different work condition conditions, on the other hand, compact structure, bearing force are big, satisfy high rotational speed requirement, are applicable to on all kinds of heavy machinery devices.
Description
Technical field
This utility model is related to high revolution heavy bearing technical field and in particular to a kind of full ball of multiple row no retainer is adjusted
Heart bearing.
Background technology
At present, existing bearing is typically by outer ring, inner ring, retainer and ball composition.Retainer effect within the bearing
Mainly guiding ball rolls on correct position, prevents ball from misplacing, but this structure is held when ball moves axially
Easily causing retainer breakage leads to bearing stuck, and retainer and rolling element sliding friction surface easily cause greatly bearing heating and mill
Damage, especially under the conditions of running up, the effect of centrifugal inertial force exacerbates friction, abrasion and heating, can cause to protect when serious
Hold frame burn or rupture, cause bearing cannot be continuing with, decrease the service life of bearing.And bearing is all by single-row
Ball ring is constituted and ball ring is made up of individual ball less it is impossible to bear larger heavy load, and anti-wear performance and intensity are all deposited
In certain defect, (internal diameter 80cm and more than) structure can not meet (2000 revs/min) weights of high revolution so existing big bearing
The use requirement carrying.
Content of the invention
In order to solve the above problems, this utility model provides a kind of full ball self-aligning bearing of multiple row no retainer.
The purpose of this utility model is achieved in that a kind of full ball self-aligning bearing of multiple row no retainer, including outer ring,
Inner ring and ball ring, ball ring is rearranged by several balls, and ball ring is located between outer ring and inner ring, the outer peripheral face of inner ring
On be provided with annular recess, ball ring be located at annular recess in.
This utility model also has a following technical characteristic:
1st, at least two, ball ring as above.
2nd, the quantity of ball ring as above is identical with the quantity of annular recess.
3rd, ball as above is completely loaded in annular recess.
4th, ball as above is spherical or cylindrical.
Effect of the present utility model and benefit are: have annular recess on inner ring outer peripheral face and fill ball, do not keep
The drawbacks of frame brings, makes ball not only can roll, on correct position, the load capacity simultaneously increasing bearing, and avoids
Stuck phenomenon when moving axially of the ball that retainer breakage causes, makes the frictional force of ball diminish, and rotation is convenient, increases
Plus bearing service life；Multiple row ball ring and the design of full ball, allow bearing can bear bigger heavy load, high revolution.Strengthen
Wearability and intensity, also increase the service life of bearing simultaneously, strengthen bearing accuracy, realize requirement and the fall of high revolution
The concentricity requirement of low axle.The different demands of all kinds of main frames working under various difference working conditions can be met it is adaptable to each
On class high revolution heavy-duty machinery device.
Brief description
Fig. 1 is bearing generalized section of the present utility model.
Fig. 2 is bearing section partial schematic diagram of the present utility model.
Specific embodiment
Below according to Figure of description citing, this utility model is further explained:
Embodiment 1
In conjunction with shown in Fig. 1-2, a kind of multiple row no retainer expires ball self-aligning bearing, including outer ring 1, inner ring 2 and ball ring,
Ball ring is rearranged by several balls 3, and ball ring is located between outer ring 1 and inner ring 2, and the outer peripheral face of inner ring 2 is provided with
Annular recess 4, ball ring is located in annular recess 4.
Ball ring described in the present embodiment is five row.
The quantity of ball ring described in the present embodiment is identical with the quantity of annular recess 4.
Ball 3 described in the present embodiment is completely loaded in annular recess 4.
Ball 3 described in the present embodiment is spherical.
This utility model is operationally: ball 3 moves direction along axle in annular recess 4 and rotates, and annular recess 4 ensures rolling
Pearl 3 rolls on correct position, prevents ball 3 from misplacing, five row ball rings and completely ball 3, allows bearing can bear bigger weight
Load, enhances wearability and intensity, realizes the high-revolving concentricity requirement requiring and reducing axle.Dynamic balancing can be met poor
The high rotating speed heavy duty machine of concentricity difference, for example, pulverize arbor, glass sand blasting machine axle etc..It is suitable for work under various difference working conditions
The different demands of all kinds of main frames made.
