Problems solved by technology

The disadvantage of this technical solution is that it cannot reduce the relative axial displacement and vibration of the inner ring and outer ring of the flange. If the axial displacement and vibration are too large, it is easy to make the flexible pad separate from the flange.
On the other hand, the flange is connected to the drive axle through the fixed screw hole of the outer ring, and connected to the powertrain of the car through the seat cover on the inner ring of the flange. Since the connection between the seat cover and the power train of the car is usually a spline connection Therefore, the manufacturing process cost is high, and the installation cost is also high

Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] In order to solve the above technical problems, the present invention provides a flange, which can reduce radial and axial displacement, reduce torsional and axial vibration, cut off the noise transmission path, and reduce the noise amplitude. Moreover, the cost of the manufacturing process of the flange is lower than that of the prior art, and the installation procedure is simpler when the flange is used for component installation.

[0034] In the following description, in order to clearly show the structure and working method of the present invention, many directional words will be used to describe, but "front", "rear", "left", "right", "outer", "inner" should be used Words such as ", "outward", "inward", "upper" and "lower" are to be understood as convenient terms, and should not be understood as restrictive terms. In addition, the ...

Abstract

The invention discloses a flange. The flange comprises a flange plate and a first connecting unit, wherein the flange plate comprises a flange hole formed in the center of a circle and at least one connecting groove, the first connecting unit is positioned in the connecting groove and is used for connecting a first element to one side surface of the flange plate, the first connecting unit comprises a bolt and a shock absorber which is positioned on the outer side of the bolt, the shock absorber is used for reducing axial displacement and axial vibration, and additionally, a noise transmission path can be cut off, so that the noise amplitude is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a flange that can reduce torsional and axial vibrations, cut off the noise transmission path, and reduce the noise amplitude. Background technique [0002] A flange is a mechanical part that connects two parts together with bolts. It is the most commonly used pipe connection part in industry, and it is also often used in machinery and equipment, such as in the transmission system of an automobile. [0003] The prior art 201320470721.X discloses a vibration-damping flange used in an automobile transmission system. The vibration-damping flange consists of a rigid flange inner ring and a rigid flange outer ring that are nested with each other and bonded to a rigid flange. It consists of a flexible pad between the flange inner ring and the rigid flange outer ring. The technical scheme realizes the soft connection between the inner ring and the outer ring o...
