Description
Technical Field
The utility model relates to a field of wheel hub bearing, concretely relates to take wheel hub bearing unit of end cover.
Background
In the application of the existing non-driving wheel hub bearing unit, a sealing end cover is not provided with a sealing lip, grease in a raceway of the hub bearing unit in the operation process can be thrown out of the end cover and a cavity of the hub bearing unit through a gap between the end cover and a magnetic ring, so that lubricating grease in the hub bearing unit is reduced, and under severe conditions, the reading of signals of the magnetic ring or a gear ring can be even influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a take seal end cover's wheel hub bearing unit.
The purpose of the utility model is accomplished through following technical scheme: the wheel hub bearing unit with the sealing end cover mainly comprises an end cover, an inner ring, a magnetic ring, a rolling body, an outer ring, a retainer, an outer sealing element, a flange, an outer sealing lip and an inner sealing lip, wherein the inner ring is installed on the outer side of the flange, the outer ring is installed on the inner ring and the outer side of the flange together through the rolling body held by the retainer, the end cover is arranged at the front end of the flange, the end cover is installed on one side of the inner diameter of the outer ring in a matched mode, the outer sealing element is arranged between the inner diameter of the other side of the outer ring and the flange in a sealed mode, the magnetic ring is installed outside the inner ring on the inner side of the end cover, the outer sealing lip is arranged on the outer.
The rolling bodies are selected from steel balls and tapered rollers.
The end cover and the outer ring are in interference fit.
The inner sealing lip and the magnetic ring are in interference fit, and the interference magnitude is 0.1-0.4 mm.
The outer sealing lip and the inner sealing lip are rubber sealing lips.
The utility model has the advantages that: the utility model discloses an increase radial seal lip and magnetic ring external diameter fit on the end cover, avoid wheel hub bearing unit operation in-process grease through the clearance between end cover and the magnetic ring throw away on the end cover with in the wheel hub bearing unit cavity, prevented that the inside lubricating grease of wheel hub bearing unit from reducing, guarantee the normal reading of magnetic ring or ring gear signal.
