Embodiment 2

[0025] Embodiment 2, the difference from Embodiment 1 is that the metal outer sleeve 11 is provided with a positioning notch 1 66, and the metal inner sleeve 22 is provided with a positioning notch 2 77, which is used for mold positioning to ensure that the sawtooth and sawtooth are aligned during the vulcanization process. The correct positional relationship can be maintained to achieve the required clockwise and counterclockwise torsional stiffness.

Embodiment 3

[0026] Embodiment 3 is different from Embodiments 1 and 2 in that the number of internal spline serrations 5 is three, and the number of external spline serrations 4 is three.

Embodiment 4

[0027] Embodiment 4 is different from the above embodiments in that the number of internal spline saw teeth 5 is eight, and the number of external spline saw teeth 4 is eight.

Abstract

The invention discloses a splined metal-rubber composite spherical hinge which comprises three layers, including a metal outer casing, a metal inner casing and an elastic rubber, wherein the internal surface of the metal outer casing and the external surface of the metal inner casing are respectively provided with splined sawteeth in the axial direction according to performance demands; the sawteeth on the metal outer casing and the metal inner casing mesh with each other and are vulcanized with the elastic rubber to form an integral body; and the shape, size and quantity of the sawteeth can be regulated according to the demands of the product performance. The shape, size, quantity and interval of the sawteeth between the metal outer casing and the metal inner casing can be regulated according to the demands of product performance to satisfy different performance requirements of different application occasions; and the interval of the sawteeth between the outer casing and the metal inner casing can be regulated to change the clockwise and counterclockwise torsional rigidity of the product so as to satisfy different rigidity requirements. The invention has the capacity for buffering instantaneous shock load and torsional load of mechanical vibrations.

Description

technical field [0001] The invention relates to a vibration damping component, in particular to a ball joint rubber elastic component suitable for various locomotives and vehicles, and belongs to the technical field of vibration damping components or components. Background technique [0002] The ball hinge rubber elastic element is a commonly used rubber-metal composite damping element, which can be widely used in various vibration damping places, especially in the bogies of rolling stock. The most common application is the three Type (metal jacket + rubber + mandrel) structure, its performance basically meets the use of various working conditions. [0003] After searching, it was found that the application number is 2007100355278, and the invention patent titled "a zigzag combined ball joint and its production and assembly method" discloses a ball joint type rubber elastic element, including a metal jacket, a mandrel and elastic rubber parts , characterized in that: there ...
