　　The disadvantages of Hydraulic cam and groove coupling:

　　A. always have a slip, slip power loss, rated efficiency of yox approximately equal to 0.96, the mechanical hydraulic cam and groove coupling and centrifugal speed type matching the relative efficiency between 0.85~0.97.

　　B, the output speed is always lower than the input speed, and the output speed can not be like the gear that exactly the same.

　　C, this cam and groove coupling needs additional cooling system, increase the investment cost and operation cost.

　　D, cover an large area, need to occupy a certain space between the power machine and working machine.

　　E, speed range is relatively narrow, and the matching speed of the centrifugal machine is in the range of 1~1/5, and the constant torque mechanical matching speed range for the 1~1/3.

　　F, no torque function.

　　G, The ability of the transmission power and input speed is proportional to the cube, input speed is too low, coupling specification increases, the ratio of performance to price is lower than the functions and the advantages of cam and groove coupling.
