Rules and standards for the use of plum coupling

The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to determine sufficient mechanical strength, there is another type of claw plate on the market that is a casting, which can be mass-produced without processing loss.So the price is much lower than machining.But the performance of the casting is not very good.It is better not to use it in some important occasions.And the claws of the casting are prone to tooth punching (claws falling off) at high speed or high load.In the high-speed and heavy-duty power transmission, some plum couplings also have the function of buffering, damping and improving the dynamic performance of the shafting.Moreover, the elastic body in the plum blossom coupling has the function of protecting the machine when the machine is running. When the machine is told to run, its torque reaches the range that the coupling cannot bear. The elastic body in the plum blossom coupling There will be a problem first, which will remind you of the problem of the machine and reduce the phenomenon of machine damage for you.

XNUMX. Rules and standards for the use of plum coupling

1. The plum blossom coupling has a good balance performance and is suitable for high-speed applications (high-speed up to 30000 rpm), but it cannot handle large deviations, especially axial deviations.Larger eccentricity and deflection angle will produce a larger bearing load than other servo couplings.Another value of concern is the failure of the plum blossom coupling.

2. Not suitable for low-speed, heavy-duty and limited axial dimensions where it is difficult to align the two shafts after replacing the elastic element.The plum blossom coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment to determine sufficient strength.

3. Once the quincunx elastic spacer is damaged or fails, the torque transmission will not be interrupted. At the same time, the metal claws of the two shaft sleeves mesh together to continue to transmit the torque, which is likely to cause problems in the system.

4. The elastic element of the plum blossom coupling is similar to the plum blossom shape. The coupling has the characteristics of compensating for the relative deviation of the two shafts, damping and buffering, small diameter, simple structure without lubrication, high load capacity and easy maintenance, and replacement of elastic elements is required. Axial movement, suitable for connecting coaxial lines, frequent starting, forward and reverse changes, medium speed, medium torque and other transmission shaft systems and working parts that require high workability.

5. Choosing the appropriate plum blossom elastic spacer material according to the actual application is a major advantage of this coupling. The different hardness and temperature tolerance allow customers to choose the appropriate material to meet the performance standards of the actual application.

The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to determine sufficient mechanical strength, there is another type of claw plate on the market that is a casting, which can be mass-produced without processing loss.Couplings are also called couplings.A mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque.Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.).It is often composed of two halves, which are connected by keys or tight fits, respectively, and fastened to the ends of the two shafts, and then the two halves are connected in some way.The coupling can also compensate for the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to deformation or thermal expansion when manufacturing and installation are not working; and Alleviate impact and absorb vibration.Most of the commonly used couplings have been standardized or standardized. Under normal circumstances, it is only necessary to correctly select the type of coupling and determine the type and size of the coupling.When necessary, the load capacity of the vulnerable links can be checked and calculated; when the speed is high, the centrifugal force of the outer edge and the deformation of the elastic element need to be checked, and the balance check and so on are required.
