Precautions for serpentine spring coupling

The two tooth surfaces of the serpentine spring coupling are composed of a plurality of curved surfaces, which can determine the contact area of the tooth surface according to the change of the load, and then can bear the load impact and change the load more, so that it is safer when the starting or load is uneven. The serpentine spring coupling can absorb a lot of vibration force through the flexible transmission of the spring. For the coupling device disassembly is difficult, even if there is a large error in the installation process will not affect the performance of the equipment, simple operation, compact structure, good transmission, reduce vibration, buffer load.

In order to reduce the fracture of the reed of the snake-shaped spring coupling, we should strive to pay attention to adjusting the concentricity error and Angle error between the connecting two axes, and try to reduce the value as much as possible than the design requirements, so as to improve the quality of the spring sheet. Special attention should be paid to the material, hardness, heat treatment quality, etc., there should be no cracks and other defects after heat treatment, and pay attention to the sharp corners and sharp edges of the reed and tooth angles. To improve the processing quality of curved tooth surface, reasonable selection of grease, can not use thinner lubricating oil, and the use of larger viscosity of aluminum disulfide grease.

The bearing vibration of the fan driving end is greater than that of the non-driving end, the bearing vibration of the fan driving end is close in size and opposite in phase to the bearing of the motor driving end, the horizontal, vertical and axial vibration of each bearing are larger, and the frequency doubling component is obvious in the spectrum, indicating that there may be misalignment between the fan rotor and the motor rotor in both fans. Fault confirmation and treatment process Fault confirmation after discussion and decision, review the alignment of fan rotor and motor rotor.

The equipment is suitable for medium and high-power transmission shafting connection of two coaxial axes, with standard compensation for the relative offset of the two axes, and buffer performance, and the working ambient temperature can be between minus 30 degrees Celsius and 150 degrees Celsius; In the installation of the equipment also need to pay attention to the control deviation, although it can allow a larger error value, but in the installation process should also ensure that in the specified value, if the error is too large, it will affect the normal operation of the machine, choose the ideal grease, to lubricate the machine, can effectively extend the use of the equipment.
