Abstract
Apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a cracking plane. The apparatus has (a) a fixture assembly for holding one internal side of the bearing stationary, and (b) structure for fracturingly pulling a second internal side of the bearing away from the one internal side along a track in a direction substantially perpendicular to the cracking plane.
Claims2
An apparatus for fracturing a powder metal bearing support having stress risers to initiate cracking along a predetermined cracking plane, comprising:
- (a) a fixture assembly for holding one internal side of said bearing stationary, said one internal side being on one side of said cracking plane;
- and
- (b) means for fracturingly pulling a second internal side of said bearing away from said one internal side along a track in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
An apparatus for fracturing an annular bearing support, fracturable at room temperature, said support having stress risers to initiate cracking along a predetermined cracking plane, comprising:
- (a) a fixture assembly for holding one internal side of said bearing support substantially stationary, said one internal side being on one side of said cracking plane;
- and
- (b) means for fracturing by pulling a second internal side of said bearing support away from said one internal side along essentially a straight path in a direction substantially perpendicular to said cracking plane and without reacting against said one internal side.
