Abstract
A crimping automobile hub bearing unit belongs to auto parts. The traditional automobile hub bearing unit has no tight axial positioning inside a bearing seat and can easily cause axial movement. The utility model comprises a bearing seat and a bearing; the bearing seat comprises a flange and a tube-shaped base body which are integrally connected; a bearing mounting cavity and a shaft hole are respectively arranged at both sides inside the base body; the bearing mounting cavity and the shaft hole are connected and are coaxial with the flange; the internal diameter of the bearing mounting cavity is greater than that of the shaft hole, so that a positioning end face for axially positioning the bearing is formed; the bearing is arranged inside the bearing mounting cavity; one end face of the bearing supports against the positioning end face; a crimping ring integrally connected with the base body is arranged on the end part of one side of the bearing mounting cavity; the end face of the crimping ring is closely attached to the end face of the bearing; and the internal diameter of the crimping ring is greater than the external diameter of an inner ferrule of the bearing. The utility model has tight axial positioning, and the bearing can not cause axial movement so as to meet the requirements of high stability and high reliability of auto parts.
Description
Technical field
The utility model belongs to the auto parts and components field, and is especially relevant with a kind of curling automobile hub bearing unit.
Background technology
Automobile hub bearing mainly is made up of bearing seat and bearing, the bearing seat of orthodox car hub-bearing unit is made up of flange that is connected as a single entity and tubular pedestal, both sides are respectively arranged with and connect and all coaxial with flange bearing installation chamber and axis hole in the pedestal, bearing installation chamber internal diameter is formed for the location end face of bearing axial location greater than shaft hole diameter, bearing installation carries out axial location with jump ring and aforementioned positioning end in the face of bearing in the bearing installation chamber.The such axial location of automobile hub bearing bearing in bearing seat is not tight, is easy to generate to move axially the high stability that the out of reach auto parts and components require and the requirement of high reliability.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is exactly to overcome the easy axially movable defective of bearing that existing automobile hub bearing exists, and the curling automobile hub bearing unit of a kind of high stability and high reliability is provided.For this reason, the utility model is by the following technical solutions:
Curling automobile hub bearing unit, comprise bearing seat and bearing, bearing seat is made up of flange that is connected as a single entity and tubular pedestal, both sides are respectively arranged with bearing installation chamber and axis hole in the pedestal, the bearing installation chamber is connected with axis hole and is all coaxial with flange, bearing installation chamber internal diameter is formed for the location end face of bearing axial location greater than shaft hole diameter, bearing installation is in the bearing installation chamber, bearing one end end face is resisted against described location end face, it is characterized in that: the end of described pedestal bearing installation chamber one side is provided with the crimping circle that is connected as a single entity with pedestal, crimping circle end face is close to bearing face, bearing is carried out axial location, the internal diameter of crimping circle is greater than the external diameter of bearing inner ring, and is convenient to bearing filling lubricating oil.
Crimping circle described in the utility model uses the riveter spreading to be processed into, before riveter spreading processing, described crimping circle is arranged on and the crimping ring that be connected as a single entity coaxial with pedestal on the bearing seat pedestal end, this crimping ring internal diameter is slightly larger than bearing installation chamber internal diameter, and the crimping ring length is less than 1/2nd of outside race external diameter and inner ring external diameter difference; Bearing installation with the described crimping ring of riveter spreading, forms the crimping circle with crimping ring bending 90 degree behind the bearing installation chamber, the internal circular surfaces of crimping ring is close to bearing face as the end face of crimping circle, and bearing is made axial restraint.
The utility model can reach following beneficial effect: the utility model adopts the crimping circle that is connected as a single entity with the bearing seat pedestal to replace jump ring that bearing is made axial location, make that the axial location of bearing is very tight, bearing can not produce and move axially, and has satisfied the high stability and the high reliability of auto parts and components requirements.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is that the utility model A-A is to rotation profile.
Fig. 3 is that the preceding A-A of the utility model bottom bracket crimping circle bending is to rotation profile.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises bearing seat 1 and bearing 2, bearing seat 1 is made up of flange 5 that is connected as a single entity and tubular pedestal 4, be provided with the axis hole 7 coaxial in the pedestal 4 with flange 5, a side processes a bearing installation chamber 8 in the pedestal 4, bearing installation chamber 8 is connected with axis hole 7 and is coaxial, bearing installation chamber 8 internal diameters are formed for the location end face 6 of bearing 2 axial location greater than axis hole 7 internal diameters, the width of the length in bearing installation chamber 8 and bearing 2 is suitable, pedestal 4 ends of bearing installation chamber 8 one sides are provided with crimping ring 9 coaxial with pedestal 4 and that be connected as a single entity, crimping ring 9 internal diameters are slightly larger than the internal diameter in bearing installation chamber 8, crimping ring 9 length are less than 1/2nd of outside race external diameter and inner ring external diameter difference, bearing 2 is installed in the bearing installation chamber 8, bearing 2 one end end faces are resisted against location end face 6, with riveter crimping ring 9 is carried out crimping processing, with crimping ring 9 spreadings bending 90 degree, crimping ring 9 internal circular surfaces are close to the crimping circle 3 that bearing face is formed for bearing is carried out axial location, because described crimping ring length is less than 1/2nd of outside race external diameter and inner ring external diameter difference, then the internal diameter of the crimping circle 3 of crimping ring 9 bending back formation is less than the external diameter of bearing inner ring, conveniently to bearing filling lubricating oil.
