Description

Highly reliable leakproofness is usherd to seat self-aligning bearing

Technical field

The utility model belongs to field of bearings, and in particular to a kind of highly reliable leakproofness is usherd to seat self-aligning bearing.

Background technique

Self-aligning bearing refers to that outer ring raceway is spheric, adapts to have angular displacement fortune between inside and outside two raceway axial lines Dynamic bearing, is primarily subjected to radial load, can also bear a small amount of bi-directional axial load.The self-aligning bearing of the prior art is being adjusted Gap can be generated during the heart between sealing ring and inner ring, causes oil leakage and foreign matter to enter Bearing inner, influences bearing Normal use, shorten the service life of bearing.

Utility model content

Utility model aims to solve prior art self-aligning bearings due to fault of construction, and there are lacking for leakproofness difference It falls into, a kind of highly reliable leakproofness is provided and is usherd to seat self-aligning bearing, good seal performance can effectively extend the service life of bearing.

The utility model is achieved by the following technical solution:

I.e. a kind of highly reliable leakproofness is usherd to seat self-aligning bearing, including inner ring and outer ring, is equipped with and is rolled between inner ring and outer ring Body and sealing ring, which is characterized in that inner ring is spherical surface with sealing ring contact site.

The key of the utility model is the design of sealing pair, and the position that inner ring outer diameter is contacted with sealing ring is spherical surface (ball Shape), when inner ring is rotated with the increasing of the amount of deflection of axis, the sealing condition of sealing pair does not have any variation, is always maintained at Ideal sealing state prevents lubricating grease leakage, improves lubricating life.

Further, the lower end of the sealing ring of the utility model is equipped with Y shape lips, and Y shape lips press against the spherical surface of inner ring On.

The Y shape lips of the utility model are rubber material, its own presses against the ball of inner ring with good toughness, lip On face and certain deformation occurs, sealing effect is more preferable.

Further, the bearing of the utility model is mounted in bearing block, and outer ring is equipped with spacer pin.

The spacer pin of the utility model can effectively prevent outer ring and rotate.

Further, the rolling element of the utility model is ball or roller.

Further, the rolling element of the utility model is at least 1 column.

The utility model has the advantages that structurally reasonable, stable and reliable in work, sealing effect is good, long service life.It uses Lubricating grease leakage can be effectively prevented in the utility model, improves lubricating life.

Specific embodiment

It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation Novel protection scope.It should be noted that unless otherwise indicated, technical term or scientific term used in this application should The ordinary meaning understood by the utility model one of ordinary skill in the art.

As shown in figure 1, figure 2, figure 3, figure 4 and figure 5: self-aligning bearing 2 is mounted on bearing base, the outer ring 3 of self-aligning bearing 2 It is equipped with spacer pin 8, two column rolling elements 4 are equipped between outer ring 3 and inner ring 6, rolling element 4 is ball, the fixed peace in 5 upper end of sealing ring On outer ring, the Y shape lips of lower end press against on inner ring 6 and occur certain deformation, inner ring 6 and 5 contact site of sealing ring For spherical surface.

When the utility model is used, when inner ring 6 is rotated with the increasing of the amount of deflection of axis, the sealing condition of sealing pair is not Any variation is had, ideal sealing state is always maintained at, prevents lubricating grease leakage, improves lubricating life.

The above various embodiments is only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned The utility model is described in detail in each embodiment, those skilled in the art should understand that: it still can be with It modifies the technical solutions described in the foregoing embodiments, or some or all of the technical features is equal Replacement；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution various embodiments of the utility model technical side The range of case should all cover in the claim of the utility model and the range of specification.
