Precautions for use of coil spring coupling

The coil spring coupling has good elasticity. The flexible effect of the spring can greatly reduce the vibration generated during operation. The service time of the serpentine spring coupling is related to its production data. For example, when selecting materials, alloy steel products with high strength are used, and some processing is also carried out to make it effective, such as heating treatment, which makes it flexible. In addition, the serpentine spring coupling is flexible because the springs on the coupling have undergone strict sandblasting, In this way, the molecular structure on the surface of the serpentine spring coupling can be compressed. These operations make it last for a long time.

The coupling is simple in structure and convenient for maintenance. There are few parts for the serpentine spring coupling, so it is light in weight and small in size, which will make it convenient for the device and maintenance. Usually, it does not need too much maintenance. The most important maintenance is to apply grease on the corresponding shaft when the device is used for a long time, which not only makes the operation smooth, There is still some noise.

The tooth shape of the serpentine spring coupling is curved: when the load is small, the straight part of the serpentine spring is basically parallel to the axis connected; When the load increases, the deformation of the serpentine spring increases, the contact camber with the tooth also increases, and the distance between the serpentine spring and the tooth contact point becomes shorter and shorter. When the stiffness increases, the relationship between the relative rotation angle of the two coupling halves and the transmitted torque is nonlinear, which belongs to the variable stiffness serpentine spring coupling.

The serpentine spring coupling is a structural metallic coupling, which transmits torque by the serpentine spring. It has good damping performance, good service life and large load variation; Good transmission speed, low noise, good lubrication, simple structure, easy assembly and disassembly, and large installation deviation is allowed.

Pay attention to the following aspects in use. Serpentine spring

1、 Installation alignment and control of correct deviation:

Although large installation deviation is allowed for the serpentine spring coupling, it should also be within the specified value during installation.

(1) For the alignment of the clearance and angular deviation between the two disc couplings, the clearance between the two disc couplings shall be measured every 90 ° during installation, and the difference between the large value and the small value shall not exceed 0.38mm.

(2) Radial deviation alignment. Place a ruler on the two lobe coupling, measure every 90 °, and check with a feeler gauge. The radial deviation shall not exceed 0.38mm.

2、 Select appropriate grease:

The temperature of oil injection point is ≥ 150 ℃, which can resist centrifugal force, has good separation stability, no impurities, and does not corrode carbon steel and nitrile rubber.

3、 Fill sufficient grease:

Sufficient lubricating grease is important for the work of the coupling, and it is recommended to check it once a year. Fill the grease with a grease dryer until excessive grease overflows from the hole.

Serpentine spring coupling has many excellent performances, such as excellent shock absorption performance and long service time of equipment; The utility model can withstand a wide range of variable loads, and can be started in work; In addition, the transmission speed is good, the working state is stable and running; The noise generated in the use process is small, and the lubrication is strong; Simple structure and convenient assembly and disassembly. The internal components of the equipment are few, so its own weight is light, and its volume is small for storage and carrying; In the process of installation, even if large errors occur, the performance of the equipment will not be affected; Simple operation and compact structure.

The serpentine spring coupling is a structural metallic coupling, which transmits torque by the serpentine spring. It has good shock absorption, good service life and large load variation; Good transmission speed, running; Low noise and good lubrication; Simple structure, easy assembly and disassembly, and large installation deviation is allowed. Although the serpentine spring coupling has so many characteristics and advantages, many brother units have changed it into an elastic pin coupling. As the user of the coil spring coupling, our company did not imitate it, but used it, and received good results.

1、 Fill sufficient grease:

Adequate lubrication is important for the work of the coupling, and it is recommended to check it once a year. Fill the grease with a grease dryer until excessive grease overflows from the hole.

2、 The working environment temperature of the coupling shall be well controlled, generally at - 18~80 ℃.

3、 Installation alignment and control of correct deviation:

4、 Select appropriate grease:

The temperature of oil injection point is ≥ 150 ℃, which can resist centrifugal force, has good separation stability, no impurities, and does not corrode carbon steel and butadiene rubber.
