　　Diaphragm couplings are widely used for shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical engineering Machinery, mining machinery, metallurgical machinery...

　　This type of coupling is equipped with elastic elements, which can not only compensate the relative displacement between the two shafts, but also have the ability to buffer and reduce vibration.The more energy the elastic element can store, the stronger the cushioning capacity of the coupling; the elastic hysteresis and elastic change of the elastic element...

　　The earliest known Mother's Day originated in ancient Greece.On this day, the ancient Greeks paid tribute to Hera, the mother of the Greek gods.Later in the middle of the 17th century, the festival spread to England.On this day, young people who are away from home will return home and give their mothers some small gifts. ...

　　Membrane stress caused by the torque of the diaphragm coupling.Suppose the transmitted torque is T (Nm), and the total number of pieces is m. For 8-hole bolts, the simplified conditions know: the torque of a single diaphragm is T1=T/m, and the force on each main bolt is F =T/4mR. ...

　　The characteristics of the drum gear coupling (compared with the straight gear coupling) are as follows: 1. The angular displacement compensation is large. When the radial displacement is equal to zero, the straight gear coupling is The allowable angular displacement is 1º; the allowable angular position of the drum gear coupling...

　　Among the wide variety of couplings, the drum-shaped gear coupling has a small size, large transmission torque, strong ability to absorb coupling errors, and excellent durability. Its function is to connect the driving shaft and the driven shaft to transmit rotation. The moment makes the two shafts rotate together, which is medium and...

　　1. Before installation, first check whether the prime mover and the working machine are concentric, whether there are wrapping paper and bumps on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the plum coupling, and whether the edges of the inner holes are There are bruises, if any, the shaft and half coupling should be cleaned up,...

　　Key points for coupling selection: ①Allowable rated torque-is the allowable value of the torque that the coupling bears in actual use; ②Allowable maximum torque-is the maximum critical value for damage to the coupling during use; ③Allowable maximum speed-need to be selected Make sure that the speed of the motor is...

　　After the coupling has been used for a period of time, it should be inspected and maintained regularly to reduce unnecessary damage. 1. Check whether the coupling body is cracked; 2. Check whether the key connection of the coupling is loose or rolling; ...
