The roller shape can also be a ball or top post, and can also be set to other shapes that restrict itself from falling off the bushing. When the Curved-tooth Gear Couplings is used, the user only needs to buckle the bowl-shaped end face with the driven shaft structure onto the bushing on the driving shaft. At the moment of starting the motor, the roller bushing, etc., will remain stationary under the inertial action, while the driving shaft has turned a certain angle, and then because the wedge contacts the roller, it will be arranged, so that the roller restricted by the bushing through hole can only move radially, lift outward, and contact the side wall of the driven shaft cup buckle. If the resistance of the material is too large, resulting in slippage, it will also be due to the action of the wedge.
The rollers will also be more and more tight, which will balance the static friction and resistance again, and drive the driven shaft. When the driven shaft and the driving shaft are not concentric, the mechanism will also automatically adjust the friction between the rollers under eccentric load due to the uneven pressure on the wedge surface, so as to achieve the purpose of automatic centering. The driving shaft assembly is composed of the driving shaft, upper and lower bushings, top post, etc. The driving shaft is connected with the motor shaft through thread, and the driven shaft is connected with the blade to be driven. When in use, it can be easily buckled and used. At the same time, the mechanism should have the function of automatic adjustment and centering.
After the Curved-tooth Gear Couplings is heated in the drying room, it will be transported to the motor assembly position, and it will be assembled in place by the secondary stroke of the jacking device. This operation process must be compact. If the conveying device and the jacking device are equipped with a device to transfer the Curved-tooth Gear Couplings from the operating device to the jacking device, it is not conducive to the package of the Curved-tooth Gear Couplings. The transportation and jacking process shall be completed on the transport device. In the production and manufacturing process, the welding accuracy requirements were met and the expected results were achieved; The welding effect is even, so that the sealing between the shield sleeve and the shell flange and the inner wall of the stator meet the process requirements.
For the vertical motor with Curved-tooth Gear Couplings installed at the shaft extension end, when the motor cannot be horizontally installed to suit the Curved-tooth Gear Couplings due to the limited conditions, the existing process method is to heat the Curved-tooth Gear Couplings and place it at the designated position, and lift the motor with a crane; Since the whole operation is carried out inside the stator, it is required that the tools should not be rusted and painted to prevent rust or paint peeling due to welding and assembly, which will affect the internal structure. The Curved-tooth Gear Couplings has a simple and reliable structure, and the requirements for coaxiality of the two half Curved-tooth Gear Couplingss are not high. When the cutting force is too large, the key will be cut and damaged to protect the components at both ends of the Curved-tooth Gear Couplings from damage.
