Problems solved by technology

The existing coupling rigidly connects the two, but when the driving shaft starts, due to the inertial load of the driven part connected to the driven shaft, the driving shaft will generate an impact load and form a large impact moment. When the driven part connected to the driving shaft is subjected to an impact load, the rigid connection between the driving shaft and the driven shaft will also form a large impact moment
It is easy to cause damage to the coupling or related transmission parts

Abstract

The invention discloses a buffer coupling. The buffer coupling comprises a driving shaft, an intermediate shaft sleeve, a porous metal pipe fitting, a screw, a driven shaft spline sleeve and a drivenshaft. The porous metal pipe fitting is pre-compressed at an original position and used for balancing the limit transmission torque of a mechanism, when the porous metal pipe fitting is subjected to the action of impact torque, the porous metal pipe fitting is further compressed to generate axial displacement, and the axial displacement corresponds to circumferential rotational motion, so that a rotating speed difference is generated between the driven shaft and the driving shaft, the transmission time of the impact torque is prolonged, the peak value of the impact torque is reduced, and the safety of a transmission shaft and parts in a transmission system is effectively protected.

Description

technical field [0001] The invention relates to a buffer coupling and belongs to the technical field of machinery. Background technique [0002] Couplings are mechanical general parts, which are mechanical parts used to connect the driving shaft and driven shaft in different mechanisms and make them rotate together to transmit torque. The existing coupling rigidly connects the two, but when the driving shaft starts, due to the inertial load of the driven part connected to the driven shaft, the driving shaft will generate an impact load and form a large impact moment. When the driven part connected to the driving shaft is subjected to an impact load, the rigid connection between the driving shaft and the driven shaft will also form a large impact moment. It is easy to cause damage to the coupling or related transmission parts. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the present invention provides a buffer coupling, the tec...
