Abstract

The invention discloses laminated rubber. The laminated rubber is provided with a cylindrical part and a spherical part, the cylindrical part can bear a larger torsion angle and lower torsion strain,the spherical part has the characteristics of good radial, torsion, bending and axial bearing capacity, and the laminated rubber has high torsion capacity through the combination mode of the cylindrical part and the spherical part, so that the torsion fatigue performance of the laminated rubber is improved. An elastic bearing comprises an inner joint, an outer joint and the laminated rubber arranged between the inner joint and the outer joint. Due to the fact that the laminated rubber formed by combining the cylindrical part and the spherical part is adopted, the elastic bearing has good torsion capacity and torsion fatigue performance, can adapt to large radial loads, and meanwhile has good bending and axial bearing capacity, so that the requirement of a helicopter for the torsion fatigueperformance of the elastic bearing is met, and flight safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of elastic bearings for helicopters, in particular to a laminated rubber and metal elastic bearing. Background technique [0002] Helicopters are an important force in national economic construction, especially in earthquake relief and emergency rescue, which play an irreplaceable role. The rotor is the key moving part of the helicopter, which provides the lift and control force required for the flight of the helicopter. Rotor technology directly affects the performance of the helicopter, represents the advanced degree of the helicopter, and is also an important symbol of the generation of the helicopter. In the fully articulated rotor configuration, there are a large number of various metal bearings in the propeller hub due to the existence of flapping hinges, shimmy hinges and variable pitch hinges, resulting in a complex structure of the propeller hub, a large number of parts, and high manufacturing cost...
