- Abstract
Self-tightening assemblies are made by tightening caused by the elastic deformation of the joined parts. It is used for mounting tires, gear crowns, active plates from extrusion dies, for making crankshafts from separate elements, for making two-piece flywheels, etc. An increase in the strength of the tube can be achieved with the help of shrinkage. It consists of a radial compression of the tube under the load of an internal pressure, by which the maximum normal circumferential stress 'σa' is reduced. Pre-tightened assemblies are frequently used in machine building due to their advantages, such as: - High transmission capacity, both for static and variable loads; - Simple execution; - Low assembly costs etc. - As disadvantages can be cited: - Possibility of loosening the tightening during operation; - Deterioration of surfaces during disassembly; - Execution in tight tolerance fields etc. Due to the complexity of the technological system of assembling parts by shrinking, experimental research is the only way to obtain satisfactory results necessary for the use and continuous improvement of technologies and equipment for performing shrinking-on joints.
