发明名称 Counterbored joint
摘要 Past applications have found that a joint becomes damaged due to the high loading and vibration loads in which it encounters during operation. The counterbored joint utilizes the flexible shim that is larger than the body receiving bore. A undercut is machined into the body receiving bore which allows for the flexible shim to be placed within the body receiving bore between the first and second step surfaces. The first step surface is parallel to the second step surface which distributes stresses uniformly and helps in sealing. The principal use is for a cylinder liner joint, however any joint that is highly loaded or encounters vibrational loads will benefit from this invention. For example, a hydraulic joint that utilizes a piston in operation may be remanufactured with this invention.
