The precision shaft is fastened and fastened by fastening bolts between the hollow shaft body and the transmission disc.

The characteristics of the straight optical axis have been very clear, but do you know about its classification? There are three main types of linear optical axis, namely, crankshaft, straight axis and flexible axis, in which the straight axis can be further subdivided, and mainly according to different purposes to be distinguished. Precision axis
The left tooth disc and the transmission hollow shaft shaft body are connected as one, the right tooth disc and the transmission disc are connected as one, and the teeth of the left tooth disc and the right tooth disc are matching each other. In this way, the teeth of the left and right teeth of the disc distribute radially and evenly on the end face of the hollow shaft body and the drive disc. In order to ensure the normal engagement of the disc, the fastening bolt is used to stop the fastening combination between the shaft body of the hollow shaft and the drive disc.
The accuracy of their mutual position is mainly determined by the position and function of the shaft in the machine. Usually the coaxiality of the Journal of the assembly transmission should be guaranteed, otherwise the transmission accuracy of the transmission will be affected. In this case, the position accuracy of the high-precision shaft is usually 0.001~0.005mm.
Straight shaft can be divided into three types: rotating shaft, mandrel shaft and transmission shaft. When rotating shaft works, it bears both bending moment and torque. It is a common shaft in machinery. And the mandrel can be used to support rotating parts, it only bears bending moment without transferring torque; and some mandrel can be rotated, such as the axle of railway vehicles, and some mandrel can not rotate, such as supporting pulley shaft.
