CALCULATION AND EXPERIMENTAL JUSTIFICATION OF DESIGN AND TECHNOLOGICAL SO-LUTIONS OF POWER HYDRAULIC CYLINDER ELEMENTS

The paper describes studies of the stress-strain state power hydraulic cylinders elements. Geometric dimensions casing and properties materials are chosen as varied parameters. controlled values levels stresses displacements. criteria weight, strength rigidity. These characteristics determine technical cylinders. Dependences criterion on parameters established. On this basis, recommendations for substantiation design technological solutions elements developed. This made it possible to develop a project technology manufacture with low material consumption. In addition, increased efficiency is provided due use antifriction coating inner surface cylinder. stress level in main cylinder body limited. area brazed joint plastic lining layer also ensured. A special configuration sealing ring used reduce losses movable connection piston body. At same time radial displacements provide acceptable contact moving fixed parts general, balanced substantiated. They high It increases their production reduces total cost. Power reasonable systems.
