Abstract
A self-aligning bearing comprises a bearing inner ring, a bearing outer ring, a plurality of rolling bodies and a retaining frame, wherein the plurality of rolling bodies are evenly distributed in the retaining frame, the retaining frame is located between the bearing inner ring and the bearing outer ring, and the periphery of the cross section of the bearing outer ring is arc-shaped. The self-aligning bearing has the advantages that after the structure is adopted, due to the fact that the periphery of the cross section of the bearing outer ring is arc-shaped, the bearing has a self-aligning function, the axis of the bearing can be automatically adjusted within a certain range to be aligned with the axis of a bearing block, the bearing is protected from damage, the service life of the bearing is prolonged, and the bearing is convenient to install.
Description
Technical field
The utility model relates to a kind of expansion mandrel and holds.
Background technique
Existing bearing; Comprise bearing inner race, bearing outer ring, a plurality of rolling element and retainer; Said a plurality of rolling element is distributed in the said retainer, and said retainer is between said bearing inner race and said bearing outer ring, and the profile of said bearing outer ring is a cylindrical body.Bearing is generally paired use, is installed in the two ends of an axle respectively, and axle is respectively installed on two bearing supports through two bearings then; Because there is certain deviation in the axle center of two bearing supports; And the profile of bearing outer ring is a cylindrical body, and the aligning performance of bearing is bad like this, is difficult to the off-axis bearing at the installation process middle (center) bearing and axially relatively rotates; Thereby cause damage of bearings, install inconvenient.
Summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provides a kind of simple in structure, long service life, expansion mandrel easy for installation to hold.
The technological scheme that the utility model solves its technical problem is: a kind of expansion mandrel holds; Comprise bearing inner race, bearing outer ring, a plurality of rolling element and retainer; Said a plurality of rolling element is distributed in the said retainer; Said retainer is between said bearing inner race and said bearing outer ring, and the periphery of the cross section of said bearing outer ring is circular arc.
Further; One side of said retainer is provided with the dust cover between said bearing inner race and said bearing outer ring; The opposite side of said retainer is provided with the sealing configuration between said bearing inner race and said bearing outer ring, and the sealing structure comprises seal ring and is located at the outer skeleton of sealing circle.
The utility model is identical with the mounting type of bearing of the prior art, just, the utlity model has certain aligning effect; When mounted, bearing outer ring is the bearing support rotating certain angle relatively, and bearing can not be damaged; Thereby prolonged working life, and, install also very convenient.Because the both sides of retainer are respectively equipped with dust cover and sealing configuration, make dustproof better with sealing effect.
The beneficial effect of the utility model is: adopt said structure; Because the periphery of the cross section of bearing outer ring is circular arc, makes bearing have the aligning effect, therefore can be in certain amplitude the axis centering of adjustable axle line and bearing support; Keep bearing not to be damaged; Thereby prolonged working life, and, easier for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1; A kind of expansion mandrel holds; Comprise bearing inner race 1, bearing outer ring 2, a plurality of rolling element 3 and retainer 4; Said a plurality of rolling element 3 is distributed in the said retainer 4, and said retainer 4 is between said bearing inner race 1 and said bearing outer ring 2, and the periphery of the cross section of said bearing outer ring 2 is circular arc.
One side of said retainer 4 is provided with the dust cover 5 between said bearing inner race 1 and said bearing outer ring 2; The opposite side of said retainer 4 is provided with the sealing configuration between said bearing inner race 1 and said bearing outer ring 2, and the sealing structure comprises seal ring 6 and is located at the skeleton 7 outside the sealing circle 6.Dust cover 5 and sealing configuration setting make dustproof better with sealing effect.
The utility model is identical with the mounting type of bearing of the prior art, and just, the periphery of the cross section of the bearing outer ring 2 of the utility model is circular arc; Make bearing have certain aligning effect, when mounted, bearing outer ring 2 is the bearing support rotating certain angle relatively; Bearing can not be damaged; Thereby prolonged working life, and, install also very convenient.
Claims (2)
