Embodiment Construction

[0053] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0054] Such as Figures 1 to 5 As shown: the metal joint bearing includes: mandrel 1, dust cover 2, dustproof lining 3, housing 4, outer ring 5, retaining ring 6, ball bowl 7, spring 8 and end cover 9.

[0055] Housing 4 as Figures 6 to 9 As shown: the housing 4 is cylindrical, and a cylindrical housing shaft hole 41 is provided at one end, and a step for installing the outer ring 5 and the retaining ring 6 is provided in the housing shaft hole 41 . The step height H1 of the retaining ring is smaller than the height H2 of the retaining ring, so that the end cover 9 can press the outer ring 5 through the retaining ring 6 to prevent the outer ring 5 from moving in the shaft hole 41 of the housing. One end of the shaft hole 41 of the housing has a large opening, and the wall thickness of the end is relatively thin. After the outer ring 5, the ret...

Abstract

The invention relates to a metal joint bearing damping and noise reduction method and a metal joint bearing. The metal joint bearing is composed of a mandrel, a dustproof cover, a dustproof lining, a shell, an outer ring, a check ring, a ball bowl, a spring and an end cover. By means of the manner that a ball head of the metal joint bearing generates axial displacement along the mandrel relative to the outer ring, the fit clearance increased due to abrasion of the ball head and the portion, bearing the largest force, of the outer ring is reduced, and therefore the impact force and abrasion between the ball head and the outer ring are reduced, damping and noise reduction of the metal joint bearing are achieved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a metal joint bearing vibration and noise reduction method and the metal joint bearing. Background technique [0002] The anti-roll torsion bar system, referred to as the torsion bar system, is used in rail transit vehicles, such as urban rail subway vehicles, high-speed EMU vehicles, trunk line railway vehicles, and trams. The anti-roll torsion bar system is a key component of a rail transit vehicle, which plays a role in improving the anti-roll stiffness of the vehicle during operation, and is used to suppress the roll of the car body under the conditions of vehicle turning and crosswind. The torsion bar system mainly consists of a vertical connecting rod assembly (referred to as the connecting rod assembly), a support seat assembly, a torsion bar assembly (composed of a torsion arm and a torsion bar shaft) or a bent torsion bar and other connecting components. With the ...
