Main propeller hub and propeller shell assembly dismounting tool and method

Abstract

The invention belongs to a tool designing technology, particularly relating to a main propeller hub and propeller shell assembly dismounting tool and method. The repairing technological level of helicopter dynamic components directly affects the quality of heavy repairing of helicopters in factories, and meanwhile, along with continuous improvement of the capacity of a company, repairing and maintaining operations of main propeller hub products are increasingly complicated and overloaded. A dismounting method and tool for disassembling a main propeller hub and propeller shell assembly of a helicopter and preventing parts from being damaged are required to be researched urgently so as to provide a convenient and effective working means for disassembling the main propeller hub and propeller shell assembly of the helicopter. At present, ready-made methods and tools do not exist, problems of deformation of upper and lower star plates, pulling damage of bearings, scratching damage of inner holes of the star plates and cross axles and the like are always caused in a disassembling process, parts are quite easily discarded as useless, and repairing quality and progress of products are affected. The invention provides the brand-new main propeller hub and propeller shell assembly dismounting tool and method. The tool is simple in structure and convenient to operate, and can meet requirements of dismounting of a main propeller hub, in a disassembling process, the bearings, the inner holes of the star plates and the cross axles cannot be damaged, the upper and lower star plates do not deform, and improvement of dismounting quality and dismounting efficiency of the propeller shell assembly during disassembling is facilitated.

Description

technical field [0001] The invention belongs to tooling design technology, and in particular relates to a dismantling tool and method for a main propeller hub propeller shell assembly. Background technique [0002] The repair technology level of helicopter moving parts directly affects the quality of helicopter overhaul when returning to the factory. At the same time, with the continuous expansion of the company's production capacity, the repair and maintenance of the main rotor hub products are becoming more and more complicated. There is an urgent need to develop a disassembly method and tool for the disassembly of the Z8 series helicopter main rotor hub rotor shell assembly and to prevent parts from being damaged, so as to provide convenient and effective working means for the disassembly of the helicopter main rotor hub rotor shell assembly. At present, there are no ready-made methods and tools. During the decomposition process, the upper and lower star plates are often ...

AI Technical Summary

Problems solved by technology

At present, there are no ready-made methods and tools. During the decomposition process, the upper and lower star plates are often deformed, the bearings are strained, the inner holes of the star plates and the cross shaft are scratched, etc., which can easily cause parts to be scrapped and affect the quality and progress of product repairs.
