Abstract
Interior astragal sealing washer formula bearing belongs to the bearing technology field. The utility model discloses axle contracting draws together outer lane and at least one inner circle, all is provided with the rolling element that is supported by the holder between every inner circle and the outer lane, the inner wall both ends of every inner circle are equipped with the chamfer, are equipped with the sealing washer with the shaft fit in every chamfer. The utility model discloses a chamfer is seted up at inner wall both ends at single -row bearing or double bearing's inner circle, has alleviateed the product weight of bearing, also can improve product sealing performance. The utility model discloses a sealing washer and shaft fit have improved the life of bearing, the condition that current relatively bearing can not appear intaking because of machining error to the requirement to the machining precision of inner circle has also been reduced.
Description
Technical field
The utility model belongs to technical field of bearings, especially relevant with a kind of inner wrap strip sealing ring type bearing.
Background technology
In prior art, bearing products inner ring is typically directly directly coordinated with axle, coordinates or processes and does not with great difficulty intake, long
Time may lead to product failure after using.
Utility model content
The problem existing for above-mentioned background technology, the utility model aims to provide a kind of good seal performance, life of product
Inner wrap strip sealing ring type bearing high, that difficulty of processing is little.
For this reason, the utility model employs the following technical solutions：Inner wrap strip sealing ring type bearing, is characterized in that, including outer ring
With at least one inner ring, between each inner ring and outer ring, it is both provided with the rolling element being supported by retainer；The inwall of each inner ring
Two ends are provided with chamfering, and each chamfering is provided with the sealing ring with axle cooperation.
As to the supplement of technique scheme and perfect, the utility model also includes following technical characteristic.
Described inner ring quantity is two, and outside inner ring, table forms the raceway accommodating rolling element, and two inner ring settings are in phase
Mutual symmetrical expression and mutually conflict are drawn close.
Following beneficial effect can be reached using the utility model：The utility model passes through in single-row bearing or double-row bearing
The inwall two ends of inner ring open up chamfering, alleviate the product weight of bearing it is also possible to improve product hermeticity energy.This practicality is new
Type passes through the service life that the cooperation of sealing ring and axle improves bearing, relatively existing bearing will not because of mismachining tolerance occur into
The situation of water, thus also reduce the requirement of the machining accuracy to inner ring.
