Abstract
This practicality is related to a kind of technical field of bearings, more specifically to a kind of sand bank vehicle wheel hub bearing.Sandy beach bearing need to work under conditions of having water, sand, stone etc., and external mud, sand, water etc. easily enter Bearing inner, and so as to cause bearing wear, short life, use cost is high.This practicality is a kind of sand bank vehicle wheel hub bearing, and including outer ring, inner ring, steel ball and retainer, retainer one end is equipped with tapered protrusion, opposite with the rectangular preiection of inner ring, is positioned；The both ends of bearing are equipped with guard circle；Guard circle is made of the first baffle ring, labyrinth ring and the second baffle ring; labyrinth ring is embedded at the second baffle ring both ends; labyrinth ring axially sets two slanting sealing strips in the first baffle ring; one of sealing strip is radially set in the first baffle ring, and the magnetic circle being embedded on the outside of the first baffle ring is additionally provided in guard circle at one end.This practicality improves the sealing performance of bearing significantly, effectively prevents external water and sundries from entering Bearing inner, substantially increases the service life of bearing.
Description
Technical field
This practicality is related to a kind of technical field of bearings, more specifically to a kind of sand bank vehicle wheel hub bearing.
Background technology
Sandy beach bearing need to work under conditions of having water, sand, stone etc., and working load is high, resistance is big, working environment
In, external mud, sand, water etc. easily enter Bearing inner, so as to cause bearing wear, short life, need to often replace bearing, take
When it is laborious, use cost is high.
Utility model content
The purpose of the present invention provides a kind of multi-layer sealed sand bank vehicle wheel hub bearing aiming at the deficiency of the prior art.
A kind of sand bank vehicle wheel hub bearing, including outer ring, inner ring, steel ball and retainer, retainer one end is equipped with tapered protrusion,
It is opposite with the rectangular preiection of inner ring, it is positioned；The both ends of bearing are equipped with guard circle；The guard circle is by the first baffle ring, fan
Palace is enclosed and the second baffle ring composition, and labyrinth ring is embedded at the second baffle ring both ends, and axially setting two is oblique in the first baffle ring for labyrinth ring
Sealing strip, one of sealing strip is radially set in the first baffle ring, and is additionally provided with and is embedded in the first baffle ring in guard circle at one end
The magnetic circle in outside.
As further improving and supplementing to said program, this practicality further includes following additional technical feature：
The material of the retainer is PA66+GF25, and tensile strength is good, enough hard, and wear-resisting, impact resistance is strong and resistance to height
Temperature.
The outer circle of the outer ring and the bore circular arc transition of inner ring.
The material of the labyrinth ring is NBR, and service life is long.
First baffle ring and the material of the second baffle ring are 08F, plasticity and good toughness.
It can reach following advantageous effect using the utility model：It in Bearing outer by increasing magnetic protection cover, greatly
The big sealing performance for improving bearing, effectively prevents external water and sundries from entering Bearing inner, substantially increases the use of bearing
Service life.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is a kind of sand bank vehicle wheel hub bearing.
Sand bank vehicle wheel hub bearing described in the present embodiment, including outer ring 1, inner ring 2, steel ball 4 and retainer 5, retainer 5 one
End is equipped with tapered protrusion, opposite with the rectangular preiection of inner ring 2, is positioned；The both ends of bearing are equipped with guard circle 3；The guarantor
Guard ring 3 is made of the first baffle ring 31,33 and second baffle ring 34 of labyrinth ring, and the first baffle ring 31 and the second baffle ring 34 are the two of " frame " shape
Half structure, labyrinth ring 33 are embedded at 34 both ends of the second baffle ring, and axially setting two is slanting close in the first baffle ring 31 for labyrinth ring 33
Strip of paper used for sealing radially sets one of sealing strip in the first baffle ring 31, and is additionally provided with and is embedded in the first baffle ring 31 in guard circle 3 at one end
The magnetic circle 32 in outside stops that water, silt particle etc. enter in bearing together by the first baffle ring 31,33 and second baffle ring 34 of labyrinth ring
Portion.Magnetic circle 32 is set, can be sensed, carries out coherent detection.
Further, the material of the retainer 5 is PA66+GF25, and tensile strength is good, enough hard, wear-resisting, impact resistance
Strong and high temperature resistant, ensure that the fixation of steel ball 4.
Further, the bore circular arc transition of the outer circle of the outer ring 1 and inner ring 2, it is easy for installation.
Further, the material of the labyrinth ring 33 is NBR, and the scope of resistance to temperature is big, and service life is long.
Further, the material of first baffle ring 31 and the second baffle ring 34 is 08F, plasticity and good toughness, is made
Use long lifespan.
In the present embodiment, refer to the improvement of structure, assembling between each part and it is fixed can be realized using the prior art,
Therefore no longer illustrate.
It is the preferred embodiment of the utility model above, the scope of protection of the utility model is not limited, for ability
The deformation and improvement that field technique personnel mentality of designing according to the present utility model is made, should all be considered as the protection of the utility model
Within the scope of.
