Embodiment 1

[0021] Such as figure 1 , figure 2 As shown, a new type of elastic coupling includes an active hub body and a driven hub body, and the active hub body is uniformly arranged with a spiral elastic body 3 and a fixed connection mechanism 4 in the circumferential direction; the spiral elastic body 3 is multi-strand stainless steel The twisted wire is symmetrically wound with an equal-pitch helical structure; the fixed connection mechanism 4 is a single stainless steel wire wound on the helical elastic body 3, and the fixed connection mechanism 4 enables sufficient space between the master and slave hubs of the coupling. The ring-shaped free deformation space makes the coupling have different rigidity in the axial, radial and torsional directions, realizes the elastic connection between the driving shaft and the driven shaft, and automatically compensates the shafting under installation and operating conditions The position offset; the helical elastic body 3 produces bending hys...

Abstract

The invention discloses a novel elastic coupler. Spiral elastic bodies and fixed connection mechanisms are evenly arranged in the circumferential direction of a drive hub body; the spiral elastic bodies are of a spiral structure formed by winding multiple strands of stainless steel stranded wires in a symmetrical mode at equal pitches; the fixed connection mechanisms are single stainless steel wires and wind the spiral elastic bodies; a flange plate and an anti-torsion base plate are arranged at the end of the drive hub body; the anti-torsion base plate is fixed between the flange plate and the drive hub body; through holes are formed in the middle of the flange plate and the middle of the anti-torsion base plate; the axes of the flange plate and the anti-torsion base plate coincide with the axis of the drive hub body; the diameter of the through hole in the middle of the anti-torsion base plate is smaller than that of the through hole of the flange plate and the middle of the drive hub body; a conical circular truncated cone is arranged at the end of a driven hub body; a circular hole is formed in the middle of the conical circular truncated cone; a cross through groove is formed in the circumferential wall of the conical circular truncated cone. The novel elastic coupler can automatically compensate for the position offset of a shaft system under the installation and operation conditions, can improve the stability of system operation, and is easy to assemble and convenient to operate.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a novel elastic coupling. Background technique [0002] Couplings are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. [0003] The existing elastic couplings are mainly used to change the stiffness and damping characteristics of the shaft system to improve the vibration characteristics of the shaft system. According to the material of the elastic body, they can be divided into two types: metal type and rubber type. As the industry pays more and more attention to the vibration and impact control requirements of power devices, and the situation is getting higher and higher, the existing types of couplings have certain limitations in...
