Diaphragm coupling several common forms of connection to the shaft
Axial fixation method:
In general, the diaphragm coupling is connected with the shaft in the process of using the more common key drive, and the key is the need to use the national standard. In fact, we all know that the motor shaft and the coupling can be selected with transition or tight fitting cooperation axial fixation. Axial fixation can be the coupling to the shoulder of the motor shaft or the choice of fixing screw fixed, simply said: there are two methods, some in the half coupling hole tapping, plus positioning screw; And some of them are located by interference fit, especially large rotating equipment, which requires relatively high interference quantity control.
Next, the small edition of the Thai Sheng manufacturer will list a diaphragm coupling to provide you with the relevant knowledge for reference:
1. Keyway type fixed diaphragm coupling: the key width and key way depth are specified by GB/T1095-2003. At the same time, there are three different tolerance ranges of looser key connection, general key connection and tighter key connection. 2, D word hole fixed: Usually, if the motor shaft is into a D font, if the positioning screw can not be fixed, the coupling hole can be processed into the corresponding size of the motor shaft D hole, with the positioning screw fixed, there is no need to worry about slipping 3, clamping screw fixed: the use of hexagon bolt tightening force, the slit contraction, and the shaft tightly clamping. This way is easy to fix and disassemble, and will not cause damage to the axis, is a very common fixed way. 4, expansion sleeve fixed (ZJM expansion sleeve with single diaphragm coupling) : by tightening the coupling end of the four positioning screws to compress the tent sleeve way expansion fixed, suitable for some large torque stepper motor and servo motor connection fixed, such as expansion diaphragm coupling, expansion sleeve blossom coupling, expansion bellows coupling, etc. 5. Fixing the positioning screws: The fixed shaft is locked with a 90º gap between the two positioning screws. The traditional fixing method may cause damage to the shaft of the coupling or be difficult to remove due to the contact between the front end of the screw and the shaft.
To sum up:
The manufacturer explains the relevant knowledge about the diaphragm coupling for you, _ brief talk to this, if you do not understand the place can feel free to consult our manufacturer, our customer service staff will be ready to explain for you. The purpose of the manufacturer: as long as the user in the process of using the coupling, easy to disassemble, safe use, is our manufacturer's good achievement.
