The cardan shaft is connected with the flanges at both ends by other high-strength bolts and self-locking nuts, and the transfer torque is transmitted through the frictional force between the flange end face key and the flange.
The bolt can only be placed from the side of the flange that matches the coupling. The nut is tightened from the flange side of the cardan shaft. The mechanical properties of the bolt and the nut should meet the specified requirements, so that well connected to the coupling.
The cardan shaft is used to couple two shafts in different mechanisms to rotate together to transmit torque mechanical parts. In high-speed and heavy-duty power transmissions, some couplings also have the function of damping, damping and improving the dynamic performance of the shafting.
The coupling consists of two halves, which are respectively coupled to the drive shaft and the driven shaft. Most of the general power machines are connected to the working machine by means of a coupling.
The height of the inner ring gear of the coupling can not be changed arbitrarily, mainly because the stroke of the gear shaping machine is limited, and the height of the inner ring gear is too high, which will cause the bed to dry, and the machining of the large gear shaping machine.
