Extruded bearing housing
View Patent ↗An extruded bearing housing is provided. The extruded bearing housing includes a radially inner ring, and a radially outer ring located concentric with the radially inner ring. The extruded bearing housing includes webs that connect the radially inner ring and the radially outer ring, and the webs are arranged at an acute angle to a circumferential direction. Openings axially extend through the bearing housing and are defined between the webs, the radially inner ring, and the radially outer ring. Adjacent ones of the webs extend in opposite directions from each other.
1. An extruded bearing housing, comprising:
a radially inner ring;
a radially outer ring located concentric with the radially inner ring;
webs that connect the radially inner ring and the radially outer ring, the webs being arranged at an acute angle to a circumferential direction; and
openings axially extend through the bearing housing and are defined between the webs, the radially inner ring, and the radially outer ring, and adjacent ones of the webs extend in opposite directions from each other.
2. The extruded bearing housing of claim 1 , wherein an inner surface of the radially inner ring includes at least one peripheral groove for supporting a radially outer bearing ring.
3. The extruded bearing housing of claim 1 , wherein an outer surface of the radially outer ring includes a plurality of radially extending tabs or a plurality of grooves for engaging an outer plastic housing.
4. The extruded bearing housing of claim 1 , wherein the bearing housing is made of aluminum.
5. The extruded bearing housing of claim 1 , wherein at least some of the openings define crush zones for deflection of at least one of the radially outer ring and the webs.
6. The extruded bearing housing of claim 1 , wherein the webs extend non-linearly between the radially inner ring and the radially outer ring.
7. The extruded bearing housing of claim 1 , wherein an axial depth of the extruded bearing housing is greater than an inner diameter of the radially inner ring.
8. An injection molded assembly, comprising:
an extruded bearing housing including:
a radially inner ring,
a radially outer ring located concentric with the radially inner ring,
webs that connect the radially inner ring and the radially outer ring, and arranged at an acute angle to a circumferential direction, and
openings that axially extend through the bearing housing and are defined between the webs, the radially inner ring, and the radially outer ring, adjacent ones of the webs extend in opposite directions from each other, and at least some of the openings define crush zones for deflection of at least one of the radially outer ring and the webs; and
an injection molded housing positioned around the extruded bearing housing, wherein pressure from forming the injection molded housing causes deflection of the at least one of the radially outer ring and the webs into the crush zones.
9. The injection molded assembly of claim 8 , wherein the acute angle is between 10-20°.
10. The injection molded assembly of claim 8 , wherein adjacent ones of the openings are different sizes.
11. An extruded bearing housing, comprising:
a radially inner ring including a radially inner surface having a peripheral groove at an axial end of the radially inner ring;
a radially outer ring located concentric with the radially inner ring;
webs that connect the radially inner ring and the radially outer ring, the webs being arranged at an acute angle to a circumferential direction; and
openings axially extend through the bearing housing and are defined between the webs, the radially inner ring, and the radially outer ring, and adjacent ones of the webs extend in opposite directions from each other.
