Working principle and the advantage of this programme are: during concrete this coupling of use, be connected to by actuating cylinder on driving shaft, driven cylinder is arranged on driven shaft.Driving shaft rotates and drives actuating cylinder to rotate, and then the active blade on actuating cylinder is rotated.Active blade rotates and the fluid in main chamber is moved, because main chamber and secondary cavity pass through channel connection, fluid motion as can be seen here in main chamber causes the fluid in secondary cavity to move, fluid in secondary cavity moves and then drives passive blade to rotate, passive blade rotates and driven cylinder is rotated, and then realizes driven shaft rotation.
When driven shaft because of overload cannot rotate time, because actuating cylinder and driven cylinder are linked as media implementation by fluid, so time driving shaft be rotated further.This coupling on the one hand, overcomes traditional coupling when driven shaft can not rotate because of overload, and driving shaft is rotated further and causes driven shaft to be distorted the situation of distortion or fracture; Protect power system on the other hand, power system can not be caused danger because of driven shaft overload.
The ingenious fluid that utilizes of this programme is as intermediate medium, and when overload occurs driven shaft, driving shaft and driven shaft generation relative movement, overcome the danger of driven shaft because of overload generation fracture.
Preferred version one: based on the preferred version of scheme, described active blade and passive blade are curved vane.In identical space, the area of contact of curved vane and fluid is larger, and when curved vane stir fluid, it is larger that fluid is subject to mixing power.
Preferred version two: the preferably preferred version of: described movement rod is screw rod, and this screw rod is threaded with fluid cylinder, baffle plate and fluid cylinder one-body molded.Screw rod is convenient when regulating the throughput of passage, and screw rod can realize driven shaft and driving shaft asynchronous rotary by the throughput of control channel, also can reach the object of deceleration.
Preferred version three: the preferably preferred version of two: described fluid cylinder is provided with safety valve.When the fluid in fluid cylinder generates heat because of the rotation of active blade and passive blade, cause pressure to increase, when this pressure reaches the parameter of safety valve setting, safety valve is opened, and plays the effect of off-load, avoids the situation occurring that coupling explodes.
Preferred version four: the preferably preferred version of three: the structure of described active blade and passive blade and measure-alike, reduces difficulty of processing, improves make efficiency, additionally improves interchangeability of parts.
