1. the protective cover adopts a sectional type structure, and the outer circle of the integral end is provided with the O-shaped sealing ring, so that on one hand, the error between the length of the protective cover and the distance between the compressor and the power driving equipment, which is caused by machining errors, can be compensated, the problem of incapability of assembling is prevented, the vibration of the equipment can be eliminated, and the noise is reduced.

2. The middle open end structure can ensure that the power driving equipment does not need to be moved when the coupler is damaged and needs to be maintained, and the coupler can be maintained after being opened.

3. The middle split surface is provided with trapezoidal teeth matched with the concave-convex parts, and when lubricating oil flows to the middle split surface opened along the top, the protruding trapezoidal teeth can prevent the lubricating oil from leaking and flow the lubricating oil back to the coupling cover, so that the lubricating oil is guaranteed not to leak.

4. Be equipped with the fender oil board near well minute face department in the guard shield, keep off the oil board and still can reduce because of the rotatory blast air effect that produces of shaft coupling except that stopping lubricating oil and getting into well minute face, can prevent that blast air effect from making gas friction themogenesis, reduce the risk of lubricating oil burning.
