What are the reasons for the failure of the coupling?

2019-9-11 21: 31: 16 Views

Couplings are widely used in the shaft transmission of various mechanical devices. During the course of use, sometimes there will be some problems, so everyone knows that it causesCouplingWhat are the reasons for the failure? Let's follow the coupling editor to find out. :

  1. When using couplings, the equipment in the shafting system, such as diesel engines, gearboxes, shafting and high-elastic couplings, must complement each other in design and use, and the level of design and manufacturing is relatively high. , The quality of the ship designed in this way is also very high.


  2. The main reason is that the vibration damper of the main engine has sunk, which makes the shafting of the coupling appear asymmetry, thereby increasing the additional torque, which makes the highly elastic coupling in use When there is a breakage accident due to fever.


  3. Because the use range of couplings is relatively wide, they are widely used in many industries.It may be improperly used in specific situations, or it may be used without consideration, which will also cause the coupling to be damaged during use.


XNUMX. Check:
1. Check the coupling body for cracks.


2. Check whether the coupling connection is tight and firm.

3. Check whether the key connection of the coupling is loose and roll the key.


4. Check if there is any when the coupling is rotatingRadial runoutAnd the end face beating.


5. Check whether the lubrication condition of the coupling is good.


6. Check the complete condition, wear condition of the coupling gear and the meshing condition of the internal and external gears.
three,maintenance:

1. Partially disassemble and inspect the equipment, clean the specified parts, and dredge the pipes and valves;


2. Replace or clean the packing, observe whether the sealing part is leaking, adjust the matching gap of each part of the equipment, and fasten each part of the equipment;


3. Carry out lubrication and anti-rust treatment on the bolts of the motor and the water pump;


4. Check the pressure gauges,Control cabinetWhether it is normal, repair or replace if damaged;


5. CheckControl cabinetOperating conditions, whether the internal components are normal
