SYSTEM AND METHOD FOR CRACKING A CONNECTING ROD - A simplified explanation of the abstract

This abstract first appeared for US patent application 17876003 titled 'SYSTEM AND METHOD FOR CRACKING A CONNECTING ROD

Simplified Explanation

The abstract describes a method for creating a cracking line in a connecting rod by etching a groove in the inner surface of the rod using a laser. The groove can be discontinuous and have multiple holes of varying depths. The method involves using a second pass of the laser to increase the depths of the holes, thereby increasing the stress concentration factor of the groove.

  • The method involves etching a groove in the inner surface of a connecting rod using a laser.
  • The groove can be discontinuous and may include multiple holes.
  • The holes are spaced apart and have different depths.
  • A second pass of the laser is used to remove more material from the groove and increase the depths of the holes.
  • This increases the stress concentration factor of the groove.

Potential Applications:

  • This technology can be used in the manufacturing of connecting rods for internal combustion engines.
  • It can improve the strength and durability of connecting rods, reducing the risk of failure.

Problems Solved:

  • The method allows for the creation of a cracking line in the connecting rod, which can help prevent catastrophic failure.
  • By increasing the stress concentration factor of the groove, the method enhances the ability of the connecting rod to withstand high loads and stresses.

Benefits:

  • The method improves the overall strength and durability of connecting rods.
  • It can increase the safety and reliability of internal combustion engines.
  • The increased stress concentration factor of the groove helps prevent sudden failures and extends the lifespan of the connecting rod.


Original Abstract Submitted

A method for creating a cracking line in a connecting rod includes etching, using a first pass of a laser, a groove in an inner surface of a larger bore of a connecting rod by removing material from the inner surface. The groove may be discontinuous and include a plurality of holes that are spaced apart and have different depths. The method further includes removing more material from the groove using a second pass of the laser to increase the depths of the holes, thereby increasing the stress concentration factor of the groove.
