Description

Ultrasonic strengthening cylinder sleeve

Technical Field

The utility model belongs to the technical field of the engine subassembly, concretely relates to cylinder jacket is reinforceed to ultrasonic wave.

Background

The engine is used as an energy conversion device and is a core component of an energy consumption mechanism, the cylinder sleeve is a core part of the engine, once the engine fails, the whole engine is scrapped, and the energy consumption mechanism cannot work normally, however, the falling-off event of the bearing shoulder of the cylinder sleeve still happens frequently; the cylinder sleeve is a cylindrical part and is arranged in a cylinder body hole of the machine body, and the cylinder sleeve is tightly pressed and fixed by a cylinder cover. The piston reciprocates in its bore and is cooled by cooling water located externally thereof. The inner surface of the cylinder sleeve is directly acted by high-temperature and high-pressure fuel gas and always generates high-speed sliding friction with the piston ring and the piston skirt. The surface of the steel pipe is contacted with cooling water, and severe thermal stress is generated under a large temperature difference and is corroded by the cooling water. The side thrust of the piston against the cylinder liner not only exacerbates its internal surface friction, but also causes it to bend. The piston also impacts the cylinder liner as the side thrust changes direction. In addition, the device is subjected to large installation pretightening force.

However, the existing cylinder sleeve still has some unreasonable factors in the using process, and when the existing cylinder sleeve is used: the outer surface of the cylinder sleeve is contacted with cooling water, severe thermal stress is generated under large temperature difference, the cylinder sleeve is corroded by the cooling water, and the service life is short; meanwhile, the sealing between the cylinder sleeve and the cylinder body hole is not enough, and cooling water outside the cylinder sleeve easily permeates into the cylinder sleeve; the rolling effect cannot be guaranteed, if a large rolling force is adopted, microcracks are easy to appear on the rolled part, so that the bearing shoulder of the cylinder sleeve falls off in the using process, and the bearing shoulder can directly fall off due to the overlarge rolling force in the rolling process.
