The allowable axis deviation of the coupling includes radial, angular and axial deviation.When installing, please adjust the axis deviation within the allowable value range of the corresponding product catalog.
When the coupling works stably, the reason for its failure is not due to excessive load and average stress, but due to excessive alternating stress, which exceeds the allowable fatigue limit and causes fatigue cracks or fractures on the compression rod near the compression ring. Then spread to the side of the tie rod, and then the coupling fails.
The selection of the diaphragm coupling should be based on the machine type provided by the complete set or the host manufacturer and the shaft power under normal conditions, and should not be over-coded.
The elastic coupling relies on the elastic deformation of the elastic element to compensate the relative displacement of the two axes, and can also buffer and reduce vibration to avoid resonance.
The high-elastic coupling is formed by clamping a metal connecting piece and an elastic element under the pretension of a bolt group, and the elastic element is formed by vulcanizing and tightly combining rubber and a cord.
Water pump couplings are small in size, light in weight, simple in structure, easy to install, and inexpensive, and are often used in small power applications.
The plum blossom coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.To determine sufficient mechanical strength.
The elastic pin coupling has a relatively large structure, simple and reasonable, easy maintenance, symmetrical and interchangeable on both sides, long life, and allows greater axial movement.
