The utility model discloses an increase a rubber lip on the magnetic encoder of non-drive wheel hub unit, rubber lip and end cover internal diameter interference fit can prevent that the grease in the raceway from flowing into end cover and ring flange die cavity from the clearance between end cover and the magnetic encoder to prevent that the grease in the raceway from reducing, effectively avoid the grease to flow into the reading that the end cover influences sensor signal.
Description
Technical Field
The utility model relates to a field of wheel hub bearing, concretely relates to take magnetic encoder's of seal lip wheel hub bearing unit.
Background
The existing non-driving hub bearing unit is provided with an end cover structure, a sealing lip is not arranged between a magnetic encoder and the end cover, and grease in a raceway easily flows into the end cover and a flange plate cavity from a gap between the end cover and the magnetic encoder, so that the grease in the raceway is reduced; and grease flowing into the end cap can affect the reading of the sensor signal.
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 lip's magnetic encoder's wheel hub bearing unit.
The purpose of the utility model is accomplished through following technical scheme: the hub bearing unit of the magnetic encoder with the sealing lip mainly comprises a hub unit end cover, an inner ring, the magnetic encoder, a rolling body, an outer ring, a retainer, an outer sealing element, a bolt, a flange, a concave cavity A, a concave cavity B and the sealing lip, wherein the flange is internally divided into the concave cavity A and the concave cavity B in front and at the back, the inner ring is installed outside the flange, the outer ring is installed outside the inner ring and the flange together through the rolling body held by the retainer, the bolt is installed at one end of the flange, the hub unit end cover is arranged at the other end of the flange, the hub unit 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.
The sealing lip is in interference fit with the end cover of the hub unit.
The interference magnitude between the sealing lip and the end cover of the hub unit is 0.3mm to 0.5 mm.
The rolling bodies are selected from steel balls and tapered rollers.
The utility model has the advantages that: the utility model adds a rubber lip on the magnetic encoder of the non-driving wheel hub unit, the rubber lip is in interference fit with the inner diameter of the end cover, and the grease in the raceway can be prevented from flowing into the end cover and the flange concave cavity from the gap between the end cover and the magnetic encoder, thereby preventing the grease in the raceway from reducing and effectively avoiding the grease from flowing into the end cover to influence the reading of the sensor signal; the interference magnitude of the sealing lip is optimally designed, so that a good sealing effect is achieved.

Description of reference numerals: the hub unit comprises a hub unit end cover 1, an inner ring 2, a magnetic encoder 3, a rolling body 4, an outer ring 5, a retainer 6, an outer sealing piece 7, a bolt 8, a flange 9, a concave cavity A10, a concave cavity B11 and a sealing lip 12.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the hub bearing unit of the magnetic encoder with the sealing lip mainly comprises a hub unit end cover 1, an inner ring 2, a magnetic encoder 3, a rolling body 4, an outer ring 5, a retainer 6, an outer sealing piece 7, a bolt 8, a flange 9, a concave cavity A10, a concave cavity B11 and the sealing lip 12, wherein the flange 9 is internally divided into a concave cavity A10 and a concave cavity B11 in front and back, the inner ring 2 is installed on the outer side of the flange 9, the outer ring 5 is installed on the inner ring 2 and the outer side of the flange 9 through the rolling body 4 retained by the retainer 6, and the rolling body 4 selectively comprises a steel ball and a tapered roller. 9 one end construction bolt 8 of flange, the flange 9 other end is provided with wheel hub unit end cover 1, and 5 internal diameter one sides in outer lane are installed in the cooperation of wheel hub unit end cover 1, and 5 opposite side internal diameters in outer lane and flange 9 are provided with external seal 7 within a definite time and are sealed, and 2 outer installation magnetic encoder 3 of the inboard inner circle of wheel hub unit end cover 1, and the design of the 3 external diameter outside of magnetic encoder has seal lip 12, seal lip 12 and 1 internal diameter cooperation contact of wheel hub unit end cover. The sealing lip 12 is in interference fit with the hub unit end cover 1, so that grease in the raceway is effectively prevented from flowing into the hub unit end cover 1 and the concave cavity a10 of the flange 9 from a gap between the magnetic encoder 3 and the hub unit end cover 1 during operation. The interference magnitude between the sealing lip 12 and the end cover 1 of the hub unit is 0.3mm to 0.5mm, so that the grease in the raceway is prevented from being reduced, the reading of sensor signals is prevented from being influenced, and the sealing effect is achieved.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
