Connecting structure for motor output shaft and rotary shaft

Abstract

The invention discloses a connecting structure for a motor output shaft and a rotary shaft. The connecting structure comprises a motor output shaft and a rotary shaft. The rotary shaft is embedded inthe motor output shaft and is provided with a plurality of bumps distributed in a radial shape along the axis of the rotary shaft. The motor output shaft is provided with a circumferential stopping slot that cooperates with the bumps. A first stopping assembly is disposed on the motor output shaft. A first groove is arranged on the rotary shaft and cooperates with the first stopping assembly. A second stopping assembly is arranged on the rotary shaft. The motor output shaft is provided with a wavy second groove arranged in the axial direction and matching the second stopping assembly. The connecting structure does not require an external connector, can directly realize the clamping connection between the motor output shaft and the rotary shaft of mechanical equipment. The axial and circumferential dual restrictions guarantee the concentricity during the assembly of the motor output shaft and the rotary shaft. The connecting structure is good in stability and avoids shaft loosening.

Description

technical field [0001] The invention relates to the technical field of connecting structures, in particular to a connecting structure used for a motor output shaft and a rotating shaft. Background technique [0002] Motors are widely used as driving power in industrial production. Motors are often connected to the rotating shaft of mechanical equipment and drive the rotating shaft to rotate, driving the operation of the entire mechanical equipment. When in use, it is very important to ensure that the concentricity of the motor output shaft and the rotating shaft is consistent. [0003] When the assembly concentricity between the output shaft of the motor and the rotating shaft is guaranteed to be good, the output shaft of the motor bears only the rotational force, and the operation will be very smooth without pulsation. When it is not concentric, the output shaft of the motor also bears the radial force from the rotating shaft. The action of this radial force will force th...

Problems solved by technology

[0005] In the prior art, the clamping device is generally used to connect the output shaft of the driving motor and the rotating shaft of the mechanical equipment, and then bolts are used to lock the connecting flange; there are also some connection methods that are mostly traditional keyway fit; there are also some special Local governments will adopt the connection method of key and tight double insurance. The above connection methods need to use external connectors to realize the connection between the motor output shaft and the rotating shaft, so there is a problem of loose connection between the motor output shaft and the rotating shaft , resulting in a connection gap between the two, causing the shaft to jump during transmission and easily broken
