Abstract

The invention discloses a buffer connection mechanism of a transmission shaft. The buffer connection mechanism comprises a driving shaft, a driving helical gear, a driven helical gear, an intermediateshaft, an intermediate shaft sleeve, a cylindrical spring, a screw, a driven shaft spline sleeve and a driven shaft. According to the buffer connection mechanism, the cylindrical spring is pre-compressed at the original position and is used for balancing the limit transmission moment of the mechanism; when the action of the impact moment is born, the cylindrical spring is further compressed to generate axial displacement corresponding to the circumferential rotation motion, so that the rotational speed difference is generated between the driven shaft and the driving shaft, the transmission time of the impact moment is prolonged, the peak value of the impact moment is reduced, and the safety of each component in the transmission shaft and the transmission system is effectively protected.

Description

technical field [0001] The invention relates to a buffer connection mechanism of a transmission shaft, which belongs to the technical field of machinery. Background technique [0002] Most of the existing transmission shaft buffer connection mechanisms are rigid couplings. When the driving shaft is started, due to the action of the inertial load of the driven shaft, an impact load is generated and a large impact moment is formed. When the driven shaft is subjected to the impact load , The rigid connection between the driving shaft and the driven shaft forms a large impact moment. As a result, the shaft coupling wears a lot and has a short life. At the same time, the power of the drive motor and the drive shaft of the protector cannot be completely transmitted, resulting in large work loss and low efficiency. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a buffer connection mechanism for transmission shafts,...
