Elastic coupling based on woven spiral spring net surface

Abstract

The invention discloses an elastic coupling based on a woven spiral spring net surface. The elastic coupling comprises a half coupling A and a half coupling B which are detachably mounted on two shaft rods respectively, the half coupling A and the half coupling B are elastically connected through the woven spiral spring net surface, and the woven spiral spring net surface is of a cylindrical structure. The woven spring net surface has the variable stiffness characteristic and can bear large load variables, transmission impact force is absorbed after deformation of the woven spring net surface, torsional vibration is reduced, and stability of power transmission is guaranteed. The elastic coupling has good damping and buffering performance in the axial direction and can bear large axial vibration impact; good inter-axis radial, axial and angular offset compensation performance is achieved, inter-axis power transmission with a certain intersection angle is achieved, and a universal coupling is replaced; and the elastic coupling is simple in structure, low in cost, convenient and reliable to install, free of lubrication and maintenance, resistant to high and low temperatures and good in extreme environment adaptability. The elastic coupling based on the woven spiral spring net surface is suitable for the technical field of couplings.

Description

technical field [0001] The invention belongs to the technical field of shaft couplings, and in particular relates to an elastic shaft coupling based on a woven helical spring mesh surface. Background technique [0002] Couplings, also known as shaft couplings, usually refer to a device used to connect two shafts or shafts and rotating parts, which rotate together during the process of transmitting motion and power, and do not disengage under normal conditions; sometimes they are also used as a This kind of safety device is used to prevent the connected parts from bearing excessive impact load and play the role of overload protection. Universal couplings are usually used when the coupling connects two shafts or shafts and rotating parts that are at an angle to each other. However, at present, the traditional universal coupling moderates the impact load and has a weak effect on absorbing torsional vibration; while the traditional elastic coupling compensates for the occurrenc...

AI Technical Summary

Problems solved by technology

However, at present, the traditional universal coupling moderates the impact load and has a weak effect on absorbing torsional vibration; while the traditional elastic coupling compensates for the occurrence of inaccurate manufacturing and installation, deformation or thermal expansion between the two shafts, etc. The offset (including radial offset, axial offset, angular offset or comprehensive offset) function is weak, which limits the application of traditional couplings in some working conditions and has a low service life
