Abstract

The invention relates to a helicopter automatic inclinator spherical hinge bearing comprehensive fatigue testing machine which comprises a support, a base, an inner ring parallel mechanism, an outer ring parallel mechanism, a power transmission mechanism and a control system. The helicopter automatic inclinator spherical hinge bearing comprehensive fatigue testing machine is characterized in that the base is fixed on the support, stand columns are arranged on the same circumference of the base at intervals, an upper cover is arranged on top ends of the stand columns, a main shaft is arranged between the base and the upper cover, the inner ring parallel mechanism is composed of an inner ring upper platform, a joint bearing, a first twist preventing arm, and an electric power booster, the outer ring parallel mechanism is composed of an outer ring lower platform, a first bearing, a first gear, an outer ring upper platform, an adjustable pressure controller, and a second twist preventing arm, the power transmission mechanism comprises a motor and a second gear fixed on a motor shaft, the motor is fixed on the base, and the second gear is meshed with the first gear. The helicopter automatic inclinator spherical hinge bearing comprehensive fatigue testing machine has the advantages of being capable of realizing fatigue experimental tests on a ball hinge bearing, a joint bearing, a double-row contact bearing, and the like in a helicopter rotor system.

Description

technical field [0001] The invention belongs to the field of fatigue test devices for spherical hinge bearings, and relates to a comprehensive fatigue testing machine for spherical hinge bearings of helicopter automatic tilters. Background technique [0002] At present, the spherical hinge bearings used in the helicopter rotor system of our country are mainly imported. The localization of the spherical hinge bearings of the rotor system is a hot issue to be solved urgently for high-performance aircraft in my country, and the high-efficiency and high-performance fatigue testing machine is one of its key technologies. Yanshan University successfully developed the first domestic spherical joint bearing fatigue testing machine in 2007. This testing machine adopts the traditional fixed-type hybrid connection of the upper and lower mechanisms. The mechanism has a large volume, energy consumption, structure, and stability. improve. Contents of the invention [0003] The object o...
