Description

Rotary phase modulation coupling and method of use

Technical Field

The invention belongs to the technical field of mechanical transmission, and particularly relates to a rotary phase modulation coupling and a using method thereof.

Background

Couplings, also known as couplings, securely connect parts of different mechanisms for rotation together and transfer of motion and torque. The couplings are classified into two major types, namely rigid couplings and flexible couplings according to whether the couplings have cushioning properties and the capability of compensating relative displacement of two axes, and are widely applied to the fields of machinery, buildings and the like. The coupling now serves as a standardized or standardized mechanical component, and the correct model can usually be determined by knowing the type and dimensions of the coupling required. However, for some applications with special requirements, the conventional coupling is not sufficient.

The rigid coupling requires strict centering of two axes, has the advantages of simple structure, low cost, reliable connection and the like, and is most widely applied. The flexible couplings can be further divided into inelastic element flexible couplings, which have the ability to compensate only the relative displacement between the two axes, and elastic element flexible couplings, which have the ability to absorb shock and cushion on the basis of this. The flexible couplings with elastic elements are limited by the strength of the elastic elements contained, and have much lower capability of transmitting motion and torque than rigid couplings and flexible couplings without elastic elements, so the application scene is limited.

In the installation process of the coupler, the input end and the output end are often installed in place in advance, and because of certain initial load, the input end and the output end are difficult to axially adjust through manual operation, so that alignment is difficult during the assembly of the coupler, and the initial phases of the input end and the output end need to be repeatedly adjusted. In addition, in some special application scenarios, the original phase difference exists between the two connected shafts or rotating parts, and even the phase difference needs to be adjustable, and at the moment, the rigid coupling or the flexible coupling cannot be effectively realized.

In order to adjust the phase difference between the input end and the output end connected to the coupling, patent document CN107642554A proposes a coupling with a fast phase adjustment. The method mainly has two defects, on one hand, the coupler is complex in structure, the input end and the output end are connected by adopting a spline pair, and the coupler also comprises auxiliary mechanisms such as a supporting mechanism and a shearing mechanism, so that the design and manufacturing process is time-consuming and labor-consuming; on the other hand, when the coupler is used for adjusting the phase, a high-pressure oil delivery pipe needs to be connected externally, which undoubtedly brings inconvenience to the use process.

Patent document CN106715941B proposes a coupling mechanism and a corresponding coupling method in which two shafts have a mechanically preset coupling phase angle, and a ratchet mechanism is used to couple two shafts with a certain phase difference. However, the ratchet mechanism is difficult to manufacture and can only be adjusted in one direction, so that the invention has very limited practicability, and an economical and practical phase modulation coupling is yet to be developed.
