Description
Technical Field
The utility model relates to the technical field of mechanical transmission, in particular to a fastening structure of a transmission part.
Background
For a transmission component consisting of two parts, namely a stator and a rotor, the rotation angle of the rotor relative to the stator will be converted into an output signal of the transmission component. The accuracy of the relative rotation angle between the rotor and the stator will directly affect the accuracy of the output signal of the transmission component. The stator is firmly fixed, and on the premise that the transmission part can work normally, the phenomenon that the transmission part is out of tolerance, has no output, even has structural damage and the like caused by loosening in the fixation of the stator, so that the transmission part cannot work normally. The manner in which the transmission components are fastened thus has an important influence on their performance.
There are many reasons for loosening the fixation of the stator, such as vibration, impact, etc. At present, the stator is mainly fixed in an axial direction in a fixing mode, so that the stator can bear axial load within a certain range. In a practical working environment, the stator may be subjected to a circumferential load in addition to an axial load. Therefore, it is desirable to design a fastener that satisfies both circumferential and axial securement of the stator.
Disclosure of Invention
