Abstract

The invention relates to a mechanical flexible connection structure and a transmission shaft device by using the flexible connection structure. The flexible connection structure comprises an inner rotating shaft and an outer shaft sleeve, wherein the inner rotating shaft penetrates through the outer shaft sleeve; a pit is formed in the peripheral surface of the inner rotating shaft; an elastic hose, which is arranged on the inner rotating shaft in a sleeving manner and covers the pit, is arranged between the inner rotating shaft and the outer shaft sleeve; a mounting hole extending in the radial direction is formed in the sleeve wall of the outer shaft sleeve; a pressing column used for pressing the tube wall of the elastic hose in the radial direction so as to press the tube wall of the elastic tube at a corresponding position into the pit is assembled in the mounting hole; a tube wall positioned between the pressing column and the pit on the elastic hose in the peripheral direction of the inner rotating shaft is a deformable tube wall capable of elastically deforming in the peripheral direction of the inner rotating shaft. Because the elastic hose is small in elastic modulus, the inner rotating shaft can adapt to the position and rotating precision of the outer shaft sleeve; therefore, flexible connection between a driving part and a driven part is realized.

Description

technical field [0001] The invention relates to a mechanical soft connection structure and a transmission shaft device using the soft connection structure. Background technique [0002] In mechanical transmissions that only transmit torque and speed, soft connection structures are often used to achieve mechanical transmission. Commonly used mechanical soft connection methods mainly include the following: 1. Use standard elastic couplings to realize soft connection; 2. Use bellows to realize soft connection; 3. Use soft rope to connect two flanges to realize soft connection. connect. [0003] However, the above-mentioned several soft connection methods have their own advantages and disadvantages. For example, the structure of using elastic couplings to realize soft connections in method 1 is relatively simple, but additional couplings are required. For micro-mechanical connections, due to the connection strength And the size of the structure, the size of the elastic couplin...
