Coupling mechanism of shafts

Abstract

The invention discloses a coupling mechanism of shafts. The coupling mechanism comprises the driving shaft (10) and the driven shaft (12), wherein the end portion of the driven shaft (12) is provided with a containing groove (13) for containing the end portion of the driving shaft (10). The coupling mechanism is characterized in that the side wall of the containing groove (13) is provided with at least two open grooves (14) at intervals in the length direction of the containing groove (13), and a locking sleeve (16) is sleeved at one end, provided with the containing groove (13), of the driven shaft (12). The coupling mechanism has the advantages of being safe, reliable, long in service life, and convenient to install, maintain and dismount.

Description

technical field [0001] The invention relates to a coupling mechanism, in particular to a shaft-to-shaft coupling structure. Background technique [0002] In mechanical transmission, power transmission between shafts is often required. For example, power transmission is required between the main shaft of a centrifugal pump or self-priming pump and the main shaft of the motor. To achieve the above power transmission, it is first necessary to connect the main shaft of the motor to the pump. The main shaft is connected so that the two shafts rotate together to transmit motion or torque. The existing two-axis online mechanism is usually composed of a driving shaft, a driven shaft and a coupling element, specifically as figure 1 As shown, the end of the driving shaft 3 extends into the driven shaft 2, the driving shaft 3 and the driven shaft 2 are provided with key grooves respectively, and the coupling key 1 is arranged in the key grooves, and the sides are locked and fixed by he...

It is difficult to meet the requirements, so that the installation, maintenance and disassembly process of the coupling mechanism is relatively difficult, and it will also lead to unstable operation and seriously affect the service life
